Older SP vs. Dual Core - Browser/Plugin Performance

Hi Gang
Have been down the block here many times. I'm very familiar with issues regarding the discontinued support of Flash Players and the frustration trying to keep your perfectly good running older G5's up to date.
Have question why I can't get the browsers in my older G5 SP 1.8 to work as satisfactorily with my two Dual Core G5's?
Details: I have 3 G5's #2 Dual Core 2.0's and #1 older SP 1.8. The Dual Core machines have #2 Browsers installed; TenFourFox ver 4, & Safari 4.1.3 with Flash Player ver 10.0 r45. Most videos in BOTH machines play just fine including UTube.
However my older 1.8 SP machine, (with browsers Safari 4.1.3, & TenFourFox ver 9), trying ALL archived versions of Flash DO NOT function properly. Each time I've used the Adobe uninstaller, then tried several/all archived players, always followed by 'Disk Permissions'. NONE will yield the same satisfactory results as with the Dual Core machines.
I'm wondering now if this situation could be related to the older 1.8 SP? Or perhaps have something to do with the Video Card in the SP machine? It's the only machine with an ATI, rather than Nvidia?
BTW, I also just tried a 'home-made altered' version of Flash, which was created by a skilled-creative person who's efforts are directed to us G5 users with NON-Intel machines. Anyway, it also failed ...
Any ideas?
Thanx
Mike

Mike-
Your video plays fairly well on Leopard in Safari (Flash 10.1) in my 2.0 GHz SP G4 w/Geforce 6800 GT.
With scaling on and full screen, the video is jerky. With scaling off, the video smooths and the video is enjoyable to watch.
HOWEVER, comparing the playback of the video on an Intel processor machine with much stronger CPU/GPU and Flash 11.1, the playback quality difference is marked; cinema-like as opposed to "web video"....
It's the only machine with an ATI, rather than Nvidia?
In your case, you have adequate GPU but inadequate CPU.
The 1.8 GHz machine wasn't good for more than 20-25 fps with HD at 480i.
128 MB VRAM and a mid grade GPU (9800 and better) are all that are needed in the graphics department.
One needs 30 fps and better to "see" smooth video.
If you were complaining about video with a FX 5200 or a Radeon 9600 I would say "get a better card".
In this case, No.
Video in OS X has ALWAYS been far more CPU bound than GPU bound... some comparisons to Windows put the diference at 5x more CPU.
BTW, Radeon drivers have, historically, almost always been better than Geforce drivers in OS X.
This is especially true in Tiger and Leopard.
I'm wondering now if this situation could be related to the older 1.8 SP?
Yes.
You are simply experiencing the limitations of the SP 1.8....... NO comparison AT ALL to either of your dual core machines, regardless of the graphics card.

Quad core i7 vs. dual core i7 if limited to 2 cores

this is kind of a limited-audience question. I work with StataMP software, which purposely limits to 2 the number of cores that a machine can use. This is very computationally intensive statistical software. I am looking to upgrade, and cannot find info on whether a top of the line i7 sandy bridge dual core machine would perform better or worse than a top of the line quad core machine that is limited by software to 2 cores.
Any ideas???
thanks!

If you don't run anything else when you run the program (just let the computer sit and run calculations) then the dual core would be the most cost effective for performance. The nice thing about having a quad core machine is that your program would be able to take full advantadge of two cores leaving the other cores free to handle any other processing the computer needs to do (operating system, other programs running at the same time). If you plan on using this program mostly when you have access to power then the quad core i7 2820QM actually can achive the same turboboost speed as the dual core (3.4ghz, the 2920XM can achive 3.5ghz) making it the faster option. One more thing to consider is how long you plan on having this laptop and if the program will eventually end up supporting a quad core system within the time you plan on having this laptop. Is this an older version of the program becuase according to this page http://www.stata.com/statamp/ it supports quad cores.

Windows Vista 64 bit w/older 2 dual core 3.0ghz Mac Pro with NVIDIA 7300

I have read a variety of the posts that have appeared here on the use of Windows Vista 64 bits on a Mac Pro. I remain confused, and but want to do this. I have a Mac Pro purchased in the Spring of '07 with dual 3.0Ghz dual core Xeon cpus and 10gb of ram, using the NVIDIA GeForce 7300 GT and running 10.5.1, with multiple drives. I want to run the 64 bit version of Vista Ultimate to use my ram, and to gain the performance this box should offer. It appears that I have three options:
1. Boot Camp: I don't know if the drivers are available, seems like the new Mac Pro drivers probably would not work, even if I could find them, since I have an older Mac Pro with a pair of the dual core Xeon CPUs. Don't know if there is an alternate source than Apple for the drivers, or a way to get around the problem in boot camp.
2. Parallels: I do not believe that 64 bit apps are supported by Parallels
3. Fusion: Their web site says they support Win Vista 64 bit, but it is not clear to me on the web site where the drivers are obtained, or perhaps they are built in to Fusion. Will I get the performance and memory benefits in fusion? Or is the OSX virtual overhead so high that this is a fools errand?
I do a lot of video editing, and fully 95% of my life is in the Mac world, but I have individuals who send files for editing, and occasionally they require Windows tools, much to my chagrin. I also have a small number of programs that need Windows 64. I occasionally am required to do some development work, and would like to use this machine for that purpose if it can indeed run Win Vista 64bit. I have XP loaded on a more modest box andit is running fine when I need it, which isn't very often.
Any help, or successful experience in running Windows Ultimate 64 bit on this hardware, utilizing its resources would be greatly appreciated.

Here are my results after further digging online and from my own experience.
Here is the procedure:
1. Check whether your Mac has the 32-bit EFI or 64-bit EFI
http://www.ihackintosh.com/2009/08/snow-leopard-106-and-64-bit-what-you-need-to- know/
2. Create a Boot Camp (BC) partition for Windows 7 x64. Resize the partition size using the slider in the BC app. Follow the instruction, insert the Windows 7 disk and reboot.
3. This will load the PC partition which is FAT formatted for now. Choose the Boot Camp partition on which to install Win 7, but choose in the option to format that partition. It will automatically format it in NTFS. Otherwise, it will not install on that partition.
Note : A "OEM System Builder" Windows 7 64-bit Professional UPGRADE install without any issues what so ever. The upgrade disk is a full install. Read this for further information:
http://www.pcworld.com/article/174288/windows7_upgrade_madecheaper.html
4. Run windows, then insert the Snow Leopard disk. It will tell you your hardware cannot support x64 version. Do the following procedure to manually install the driver:

5. Then update Boot camp using Apple Software Update in Windows.
6. All hardware works fine except the sound. The sound only comes out of the internal speaker, even when headphone or speakers are plugged in the jack. Installing the Realtek High Definition Audio Codecs driver in order to fixe the problem. Shutdown and reboot to make it applicable. Try a second time if it still does not work:

LE 9.0 performance on Mac Mini (dual core) Vs. iMac (quad core)

I am in the process of evaluating options to replace my 2007 MBP with a faster DAW. I am on a budget so while I am looking for performance improvements over what I have, I don't need overkill either. I am considering the 2011 Mac Mini (2.5 GHz, dual core) and the 2011 iMac (2.5 GHz quad - core). Whichever configuration I choose, I will bump up RAM to 8 GB.
I use LE 9.0 and a Presonus Firestudio Project and would like to know whether what kind of performance improvements I will see between the two options I am considering. I use a lot of plugins, and an external Firewire 800 drive for recording. Obviously with the Mini, I will have to buy an optical drive as well. I already have two monitors, keyboard and mouse.
The only thing that worries me about the Mac Mini is the slower 5400 rpm hard drive. While I plan on using an external drive for recording, I am concerned because of the number of plugins and sample files that need to load during recording / playback.

IS THE SITUATION HOPELESS
I used Target mode to transfer files to a new i7 iMac running Snow Leopard 10.6.8 from an older Dual core Intel machine (EMC 2105) also on 10.6.8. but originally Tiger 10.4. The operation was successful and I ejected the disk icon from the new machine and powered down the old machine. When this was restarted the next day there was a grey screen with flashing Mac symbol alternating with a 'no entry' sign and occasionally a question mark.Keyboard and mouse were unusable so k inserted the original instal disc (No.1 for 10.4. with installer 1.0.4) which came with the machine in 2006 in an attempt to boot from this. The ensuing window said this was not possible and now it cannot be ejected.I have tried everything ! It offers Disk Utility and other options like Terminal but that doesn't work either.I 'repaired disk' and that was pronounced o.k. None of the various keystrokes at start up will work, and the computer will only offer the installer disc continually.The only option would seem to be is to erase the hard drive completely from the disc in the machine.I don't want to do this as there is still material which I need to recover. I think the drive has in some way been corrupted by using it in target mode, and I don't know if there are any other options to try.
Please tell me how to get this disc to eject !

Have you seen this type of problem before? I think it could be a serious issue for anyone in a similar position.
No; but then, I've not had occasion to use TDM. I've been using firerwire drives for over 10 years, both FW400 and FW800, with no issues except a bit of instability using a B&W G3 machine.
TDM should be safe. Using cautious, manual copying of files from the Target machine to the Host machine should not result in unexpected loss of files or damage to the Target drive's directories. It should behave exactly the same as if it were an external (to the Host) firewire drive.
• I don't suppose there is anything I can do to 'put back' lost items from a separate Time Machine drive which has an up to date backup on it.
There is probably a way to do that - seems to me that's one of the reasons for a Time Machine volume.
On the other hand, if the Time Machine volume is rigidly linked to the now-absent OS on the original drive, there may be no way to effectively access the files in the TM archive.
I know that using a cloned drive would work well in this instance.
I have no experience with Time Machine, so perhaps someone who has will chime in with suggestions.
With the machine in TDM with the other machine, have you tried running Disk Utility to see if you can effect repairs to the drive?

Jdeveloper dual core processor performance problem

I have a dual core 2.4 ghz processor and 2 gig of ram and Im running Jdevloper 9.0.5.2 and my performace is terrible. Other developers in the company have non-dual core processors and they can start up in debug mode using the Jdeveloper embedded oc4j our application in 10 seconds where it takes me 4 min!!!!! It is a struts,ejb web application. Is there anything I can do to help in debug mode??? cheers.

Hi Bernard,
Which version of McAfee are you using?
On my (personal) laptop, I'm using McAfee VirusScan 9.0.10. I don't frequently run JDeveloper on this laptop, but when I do, it's not experiencing signficant startup delays (it's a very low power machine: PIII 650 512Mb)
McAfee VirusScan seems to have very few configuration options (noticably different from Norton, which I use on my corporate desktop machine). I specifically remember changing the "File Types to Scan" option to "Program files and documents only". You can get to this by right clicking the "M" notification area icon, VirusScan->Options menu, Advanced button on the ActiveShield page.
In Norton, I think I have it configured so that it only scans files on write rather than on read. I also exclude directories which contain jdeveloper installs or other large Java apps (although scanning only on write elliminates most of the performance problems anyway and still leaves your system reasonably secure).
The easiest way to convince your MIS dept that the virus checker is the source of your problems might be if you ask them to allow you to turn it off in order to test the difference it makes to performance. It's a reasonable request to make if you're trying to elliminate possible causes for the slowdown (from the description you gave, it does sound like the AV upgrade is the first place I'd start looking).
If the virus checker is the source of your problems, you'll probably be seeing massive slowness in most large Java applications that have a large number of JARs on their classpath.
Thanks,
Brian

Can older dual core iMac be external monitor to new (lion) imac

If yes, how do they need to be connected and configured?

Thanks, classic II for the reply. You are right--I should consider configuring my old Mac to be a wireless device if/when I get a new iMac, however I still would need my flash drive to have embroidery designs on it in order to get the designs into xp under bootcamp.
It was painful for me to get my dual core iMac upgraded to 1 meg for snow leopard. I could drive 50 miles to an authorized apple person, leave my iMac and he would order and install the 2 gig memory and in addition charge me $300 to fix the cd drive that was barely off warranty or do what I did. Local apple store would install a half Meg of memory but couldn't do the ordering. So I ordered 500 meg memory from on line apple store, had it shipped to my house, and then had apple store install it--to get me to 1 Gig, so I could install snow leopard--I think the apple store installed it for no charge since I ordered the memory from on line apple store, and didn't have to drive 50 miles, one way--twice.
What I have is working for me, so I guess I'll just watch what happens with lion and icloudI and apple tv (and bernina v6 software which only runs under windows7 on macs) and move on to new iMac when things are settled.

Old macbook air dual core 1.4 or 1.6 VS Mac Os X Lion performance

what are your experience using Mac os X Lion with old mac book air ( dual core 1.4 or 1.6 )

thanks for that info guys. I will download the 10.7.2 update and see if that fixes it.
regarding booting into safe mode: I haven't tried that but I am able to boot the computer up normally after the crash. It's just annoying that I have to reboot it at all.

2 Dual core intel xeon vs quad core. Whats the difference??

I came across someone who's selling his mac pro 1.1 (aprox 2-3 years old machine) which hosts 2 dual core intel xeon processors 2.66 Ghz (4 total cores) with an L2 cache of 4 MB per processor and 3 gb of RAM. He is asking for 1200.00
I wonder:
1. is there a significant difference between the machine described above and the new 2.66GHz Quad-Core Intel Xeon 3500 series processor machines Apple offers?
2. Is 1200 a good deal considering its a 2-3 year old machine? how much would it cost me brand new?
3. I am planning to purchase the machine to use Logic Pro 8 (considering to upgrade to 9) which I currently run on my mac book intel core duo 1.8 GHZ. Which of the two machines will be optimal for it?
Thanks in advance for your time!

Using the scores on the GeekBench site, I show that a Mac Pro 1,1 2.66GHz gets a score of 4544.
http://browse.geekbench.ca/geekbench2/view/218641
The Mac Pro 4,1 Quad Core 2.66GHz with all its Nehalem glory gets a score of 9256.

Benchmark tests versus real-world performance, along with your mileage, may vary. But that should give you an idea of what kind of what you're getting.

Unexpected reboot during simulation using multisim on AMD dual core processor

We are using NI-multisim 10 in a classroom environment and are experiencing sudden reboots during simulation without giving any error or warning. This happens on multiple machines, all being Dell Optiplex 740 with AMD DC 2Ghz as processor. Since these problems happen so frequently, making teaching quite impossible, we have shifted PC-room and are now using older machines. On these machines - Dell GX280 using intell P4HT-2,8 Ghz - we experience no more problems.
Is this reboot problem related to the article : Unexpected Errors with DAQ Device on AMD Dual Core Machine (http://digital.ni.com/public.nsf/allkb/9CE22FE099AFB8BF862572FF007A5D45) and what do we have to do to fix this problem?

Nic
Can you verify your driver versions? Make sure that you are running the latest versions of NI drivers to ensure proper compatibility. If possible, you might try upgrading to multisim 11. If this does not solve the issue, try the single processor workaround in outlined in the following KB:
http://digital.ni.com/public.nsf/allkb/D0FC3BE7D9F331398625731A005D76B8?OpenDocument
Altough it is surely decreasing the performance of the system, certain cases have shown that there is no other possible workaround unfortunately.

Dual 2GHz or Dual Core?

Looking in to getting a refurbed G5 tower. I was wondering if anyone knew of any drastic differences between a Dual 2GHz Powermac G5 and the new Dual Core 2GHz model. Like different PCI slots or something. Also, would there be any performance gain between the two 2GHz processors and the Dual core 2GHz?
And yet another question: Would I need an adapter to hook up an older ADC Studio Display (LCD)?
iMac G5 17" 2GHz | iBook G4 14" 933MHz | eMac 700MHz Mac OS X (10.4.4)

I would same there is a BIG difference
Atleast performance wise i have seen a 10% increase
compared to the dual model.
I would say that the 2x1MB L2 cache is a good thing -
Old model had 2x512kb
Also - The DDR2 seems a nice addition and perhaps
most important is the PCI-E bus.
Also the new machine is way more silent than old Dual
machine.
I notice the same with mine. This unit is super quiet compared to the 3 previous PM G5s I owned. The CPU fans run at a constant 600RPMs and never rev -- no matter what I'm doing. Also, this unit multi-tasks much better. I would go with the newest model.

Quad core vs Dual core, and Inel graphics

Hi all,
I’m trying to decide between a 2012 quad core 2.3GHz i7 and a 2014 dual core 2.6GHz i5. Yes, I wish they had a 2014 quad core Haswell with upgradeable RAM and a second HD bay like the 2012, plus a faster clock speed and Iris Pro graphics, but they don’t.
The main differences I see are listed below. I didn’t list the soldered on RAM in the 2014 because I’d be ordering it maxed out with 16GB of RAM. The same with the 2012; I’d be buying and installing 16GB of RAM. So in that respect, they’re even. And price comes out about the same, $900.
             2012 Quad 2.3 i7              vs        2014 Dual 2.6 i5
2012 Ivy Bridge quad      vs        2014 Haswell dual with slightly faster single core scores
Intel 4000 graphics         vs        Iris (5100)
FireWire                          vs        2nd ThunderBolt 2 port
Mavericks capable           vs        Yosemite
802.11n Wi-Fi                 vs        ac
I’m decided on 3-4-5. My main questions deal with cores and graphics.
Question 1 is about cores. I’ve read from some people on other sites that for my low level use (email, MS Office, browsing, Youtube) I won’t even be accessing the extra cores on the quad, and that the unmaxed dual cores with a faster clock speed and Haswell CPU should actually work faster in my situation. So that’s my question. Is that true? And is that likely to hold true in the future with the trend in apps related to my usage (the quad core should still be “unnecessary” in the next 5 years or so, given my usage)?
Question 2 is about the graphics. I’ve read wildly different estimates as to how much faster Iris is than the 4000 (anywhere from about 10% to 90%). Anyone know how much difference I’m likely to see between the two, given my usage? And is that likely to hold true in the future with the trend in apps related to my usage (higher graphics intensive apps playing that much better on Iris compared to 4000, again, given my usage)?
I’m trying to buy for now, but I tend to keep my Macs for 6-7 years, so I’m also trying to look at the future.
Any benchmarks, facts or educated opinions are welcome.
Thanks!

All other things being equal 4-cores are twice as fast as 2-cores. This is regardless of what you are doing. The only way a 2-core processor would be as fast is if it were run at twice the clock speed. But the 2-core CPU is only clocked around 10% or so faster. Now, for all that you claim you will be doing the relevant question is do you need 4-cores. My answer is that you don't. But the 2-core machine will be slower - all things being equal.
Iris is a far better GPU than HD4 or 5000. But not as fast as a discreet GPU with better performance measures. Again, you don't really need high-power GPU. Iris should meet your needs adequately for now.
But remember you want to keep the computer for 6 or 7 years. No one knows what your needs will be then. You may find whatever you buy today that meets today's needs will be inadequate for tomorrow's.
Your comments on graphics pretty much confirm the majority of what I've been reading on other sites.
The conflict is with cores. About half the people are saying for low CPU intensive tasks 4 cores are totally unnecessary, while the other half says they'll make things faster no what the task (one thing all seem to have in common is they're totally against the 2014s).
So it seems I'm left with the decision between faster performance vs better graphics.
I appreciate your input.

Between the 13-inch and 15-inch Pro, what difference will the Quad make over the Dual Core processor?

I'm browsing through the MacBook Pros and just wondering if the Quad core will make alot of difference over the Dual Core? Would there be any noticable performance differences? Would the 0.2 (if that's the correct number) GHz make a difference in things such as garage band and streaming wireless video?

A difference? Yes, but I doubt you'd be able to tell the difference moving back and forth between the two machines.

Power Mac G5 Dual Core Screen Goes Black Randomly But Seems To Still Be Running. I have to Force Quit

I totally just typed way to much info in the title.
In any event, my G5 Dual Core's(late 2005) screen will randomly go black with out notice. Its happend while designing in illistrator and also while browsing google(primarly the use of my comp is graphic design). The fans stay on and it sounds to still be fully running however the screen will not wake up and if i tap the power button it doesnt wake up either. I reset the "PRAM" while booting up, i toggled my screen saver/power saver also so its "never".
I thought the HD was faulty cause it sounds like a light saber at times... I figured the OS was crashing(im ingorant) so I bought a new one and more ram as well. I've installed the HD and am waiting for 10.3 OS to get here in hopes that the new HD and OS will not crash(again that was my educated guess as to what the issue was).
Is it a video card issue? faulty cable you think(VGA to DVI 17" Samsung)?
Thanks so much in advance for any and all feed back along with the patience of a newbie to the forum/community world.

HT3964 My MacBook Pro i5 Dual Core has a hardtime waking up when the computer is put to sleep and only when it goes to sleep and has been asleep for a while. The indicator light flashes on and off for a while and then freezes. I've done an SMC reset once.

Does any one have the same problem with their MacBook Pro i5 Intel Dual Core? If the computer goes to sleep (not the screen) and is asleep for a while, when I try to wake it up it doesn't respond. I have to power it downn and restart it and sometimes it takes two or three attempts. Otherwise it works fine. I upgraded the memory to 8 GB. That is the only alteration doen to it. I've performed one SMC restart and now it wakes up but it takes a while and a gray screen shows up. When I insert a DVD it won't start automatically I have to start the application in order to see it. Any suggestions?
