Noticeable difference between 2.6ghz and 2.7ghz Retina MacBook Pro?

I see its $250 extra to top-off the CPU for a 100mhz boost. Does anything else change like cache? I find the upgrade price unreasonable.

The 2.7 GHz processor includes 8 MB L3 cache compared to the 6 MB L3 cache on the 2.6 GHz processor. That certainly will help performance, so you may need to wait a while for the benchmarks that will compare both options. Barefeats does useful benchmarks but I don't know when they'll publish results of course. How you plan to use the laptop may determine if the faster processor and large L3 cache is important. If it will be doing heavy lifting such as video processing, Final Cut Pro X video renders or other high-end software, then you want as much power as you are comfortable buying.
This machine is not user-serviceable in any way, so you'll never have a second chance to upgrade any of the typical components. It's unusual in a laptop to design this way but it does allow for the thinnest Pro laptop on the planet. You really should consider AppleCare since any 'repair' will be very costly if done outside the warranty period.
Given you can't upgrade it later, I'd tend to max it out if you can afford it. As mentioned, the memory upgrade to 16 GB may be the best purchase upgrade you can do. The SSD upgrade to 768 GB may or may not be important depending upon how you will use the laptop. If it's your main computer but you have very large files such as video, you may eventually want an external drive using hard disks to store that kind of data. As long as you consider that, then you may be quite happy with only the 512 GB SSD option.
This machine will be so beautiful and quite an impressive performer. Good luck with your purchase.

Heat and Fan on Retina MacBook Pro

Hi Guys,
This is my first post in the forums and I just wanted some advice on an issue. I know there are existing discussions - but I've read conflicting answers in each. I'd like to know if the fan and heat I'm experience on my brand new 15 inch mid-2014 Retina MacBook Pro is normal.
I use Adobe Premiere Pro CC to edit 1080p video for a YouTube channel. I've noticed that after I begin exporting the fans kick in within seconds and the heat jumps up substantially. Idle, the temperature I've measured with SMC fan control is roughly 35-40 degrees, but within a minute of exporting - this jumps up to around 98/99 degrees. I understand that the fans would start after a certain amount of time and that the temperature would rise. But is it normal to rise to 99 degrees????
I've not noticed this with games, but just when exporting.
Thanks for any help.

That screen shot is very helpful. You have a four core CPU and each core can handle two threads so the %CPU can be over 100%. In your case, it's over 700% total usage with 800% being all there is available, so your rMBP is working very hard indeed. While I start cranking up the fan speed using smcFanControl just as you are, there's just so much the fans can do given that load. And we don't know how hard the graphics coprocessor is working, and that just adds more heat. I suspect the lower temperature may be because the intake ports may have been partially blocked on your lap; it really doesn't take much given their location. It looks like your laptop is doing the best it can.
There's a reason why five large fans were used in the Mac Pro towers (not counting the graphics card fan).

Is there a noticeable difference between 1.3 and 1.7 processor speed

Is the 8gb worth it compared to the 4gb? Is there a noticeable difference between a i5 and i7 core processor?

I am looking to buy a 13 inch mac book pro. I know that there is a 4gb version with a i5 core processor and also a 8gb with a i7 core processor. I am wondering if buying the upgraded one is worth the money. I play World of Warcraft so I am also wondering if the upgraded one will play the game better. Thanks.

Welcome to Apple Support Communities
The 13-inch MacBook Pro won't work correctly with the game. Go for a 15-inch MacBook Pro or an iMac. That's caused because of the GPU. The 13-inch MacBook Pro has only got an integrated GPU that isn't designed for games.
Apart from that, if you are decided to buy the 13-inch MacBook Pro, get it with 4 GB of RAM. You can upgrade it to 8 GB yourself and you will save money without voiding your warranty. Also, for games, you will note the difference with an Intel Core i7, even if the Intel Core i7 that has got the 13-inch MacBook Pro isn't the best i7

Differences between the Mac and PC versions of Premiere Pro CS5

Hello. I am considering to buy the Educational version of Adobe CS5 Production Premium (mainly using Illustrator but once in a while photoshop and Premiere). For Premiere CS5, how is the Mac version compared with the Windows version? Is it better or the same? Thanks

> I'd add that it looks as if some of the Mac documentation is just...missing?
That may very well be the case. I was only in charge of the Premiere Pro documentation for a few weeks (part of June and part of July), and that wasn't enough time to get it into the "I will stake my reputation on it being complete and correct" state that I took years to get the After Effects documentation into.
If you see a gap or error, please leave a comment on the relevant page(s) of the document so that the people who are now in charge will see them. These comments are the most direct line of communication that you have with the documentation team.
Now that I'm in Technical Support, I'll do what I can to advocate for more comprehensive documentation in Help and such.

How do I turn off podcast syncing between my iPhone and iTunes on my MacBook Pro?

Hi all.
So yeah... updated my iTunes today (along with the rest of the Mavericks OS X Update Version 10.9.3) and now all the podcasts I subscribe to on my iPhone have shown up in the Podcasts section of iTunes.
Very nice of you, Apple, but I don't want them on my computer. I don't listen to them on my computer. I listen to them on my iPhone. So I'd love to find out how to turn off this mystery syncing if anyone has any insight.
Many thanks in advance!
J

In iTunes on the desktop open the preferences & look in the 'Store tab'.
There is a checkbox for sync podcast subscriptions, disable that & see if it helps.
It isn't clear if this syncing is part of iTunes & iOS syncing (why isnt it under the device section of iTunes?), iCloud or via an app store account.
It looks like it is a feature of the App store - but I don't recollect ever signing into the store in the podcasts app?!
If the above helps submit feedback to Apple since this seems less than clear…

Differences between 2 pass and 1 pass compressing in compressor 2.0

Is there a noticeable difference between 2 pass and 1 pass compression? It seems to me that sometimes 1 pass looks better than 2 passes. Strange...
Thanks,

Hey Girshon
this is more of a compressor forum question, but i can answer it here
theoritically, a 2 pass VBR encode is a MUCH better option if you are limited to space with VERY complex scenes. a cbr encode is optimal for short encodes, or encodes where you have NO space limitation. of course this is how most encoders work.
in compressors case, for SOME reason (unbeknown to me) a 2 pass vbr does not encode to a quality that where i can call acceptable, especially with accepatable bit-rates.
this problem has seemed to come in compressor v2. a lot of people that use this version of compressor seem to recommend a CBR in compressor or a 2 pass vbr IN DVD SP.
compressor v1 seems not to have this problem however. as a matter of fact, a lot of other DVD encoder, software or hardware dont seem to have this problem.
if you do a search for 2 pass vbr in the compressor forums, you will see all the quality problems associated with compressor 2.

Is there a noticable difference between2.3 ghz, 2,6ghz and 2.7ghz. and is it worth paying to upgrade from 2.3ghz to a higher amount of ghz

is there a noticable difference between 2.3ghz, 2.6ghz and 2.7ghz and is it worth the upgrade to a higher amout of ghz

going from 2.3GHz to 2.7GHz you might notice the difference.....
but going from 2.6GHz to 2.7GHz, don't even waste your money....
if you'll be using it for everyday use, then 2.3GHz will do just fine....
however, if there's photoshop and some video editing happening, then 2.6GHz would be better suited for you....
or, go with the 2.3GHz base model then upgrade it to 16GB of RAM and add a SSD to get the best price - performance ratio...
good luck...

Is there a noticeable difference between Dual Core i7 and Quad Core i7?

Hi everyone.
I'm going to be a college freshman this fall. I'm looking at 13" MacBook with Retina Display with dual core i7. I'm also looking at the 15" MacBook Pro with Retina Display with Quad Core i7. I want to major in science and have a concentration in photography, which means that I will run programs like Excel, PowerPoint (or keynote), and Photoshop.
Anyways, will there be a noticeable difference between a Dual Core i7 processor and a Quad i7 processor?
Thanks!

Ceteris Paribus, the quad-core will be twice as fast as the dual-core.

What's the difference between the TVSU and TVUR+TI?

What's the difference between the TVSU and TVUR?
I got 3 critical, 17 recommand and 23 optional updates, when I use TVSU.
But I got 2 critical, 17 recommand and 19 optional updates, when I use TVUR combined with ThinInstaller.
It seens missing 1 critical update and couple optional updates.
Also, my bluetooth led indicator is off all the time, no matter my bluetooth is on or not.
Because the led indicator is off when my bluetooth connected and transmited files to other BT device.
I am 100% sure the led indicator is off when the bluetooth is on.
I got this fixed when I use TVSU. It fixed it automatically.
But now, I can't fix it.

Difference between 21.5" and 27" iMac (GHz)

I'm looking to buy a new iMac for performance-intensive work on applications like Final Cut and After Effects.
Is there a noticeable difference between the 21.5" iMac (2.8GHz Quad-Core Intel Core i7) and the 27" iMac (3.4GHz Quad-Core Intel Core i7)?
And by that I mean is the $500 or so price difference going to be readily apparent in how fast the the computer is?
Additionally, each computer would have 16GB of RAM, and I suppose I'd get the AMD Radeon HD 6970M 2GB GDDR5 for the 27" vs. the AMD Radeon HD 6770M 512MB GDDR5 for the 21.5" if that would make a difference.
Thanks!

Hello Sam.
The 27" is worth the $500 for the screen real estate alone in my opinion. I just replaced a 3 year old MacPro at work with the 27" i5, iMac for my graphic designer who uses Final Cut Studio as well as several Adobe products to produce HD video. The iMac has 16 GB RAM, 1TB HD, 1GB video RAM and far out performs the MacPro that has 20GB RAM. My designer went from a 20" Apple Cinema monitor on the MacPro to the 27" iMac and absolutely loves it. He tells me that the rendering speed is much faster than the MacPro. I'll assume you will get similar performance with the 21.5", but we made the decision to pay for that 27" display and do not regret it at all.
Hope this is helpful.

X100e RAM Question (difference between PC2-5300 and PC-5300)

Hello,
I am about to upgrade my x100e's empty RAM slot with 2 GB
I already found out here that best RAM for x100e is :"PC2-5300 DDR2 SDRAM 667MHz SO-DIMM-MEMORY"
In my local store they have SO DIMM PC-5300, 2 GB, KINGMAX, DDR2 667 MHz.
So what is difference between PC2-5300 and PC-5300. Can i buy that kingmax pc-5300, is that compatible with my x100e and will it be slower then recomended PC2-5300?
please help

It looks like it's a mislabelling by the store... It should be called PC2-5300. AFAIK, if it's DDR2, it should be PC2.

What is difference between sy-tabix and sy-index.

SAP Seniors,
Can you please let me know what is difference between sy-index and sy-tabix.
I read the SAP help, it is confusing for me. it looks like both are same from help. please help me.
Thank you
Anitha.

HI,
Here is a brief description of difference between SY_TABIX and SY_INDEX and using them with several conditions.
SY-TABIX
Current line of an internal table. SY-TABIX is set by the statements below, but only for index tables. The field is either not set or is set to 0 for hashed tables.
APPEND sets SY-TABIX to the index of the last line of the table, that is, it contains the overall number of entries in the table.
COLLECT sets SY-TABIX to the index of the existing or inserted line in the table. If the table has the type HASHED TABLE, SY-TABIX is set to 0.
LOOP AT sets SY-TABIX to the index of the current line at the beginning of each loop lass. At the end of the loop, SY-TABIX is reset to the value that it had before entering the loop. It is set to 0 if the table has the type HASHED TABLE.
READ TABLE sets SY-TABIX to the index of the table line read. If you use a binary search, and the system does not find a line, SY-TABIX contains the total number of lines, or one more than the total number of lines. SY-INDEX is undefined if a linear search fails to return an entry.
SEARCH <itab> FOR sets SY-TABIX to the index of the table line in which the search string is found.
SY-INDEX
In a DO or WHILE loop, SY-INDEX contains the number of loop passes including the current pass.
Hope this helps.
Thank you,
Pavan.

What is difference between sy-index and sy-tabix and where both are using ?

what is difference between sy-index and sy-tabix and where both are using ?

hi nagaraju
sy-tabix is in Internal table, current line index. So it can only be used while looping at the internal table.
sy-index is in Loops, number of current pass. This you can use in other loop statements also (like do-enddo loop, while-endwhile)
SY-INDEX is a counter for following loops: do...enddo, while..endwhile
SY-TABIX is a counter for LOOP...ENDLOOP, READ TABLE...
Here is an example from which you can understand the difference between sy-tabix and sy-index.
Itab is an internal table with the following data in it.
id Name
198 XYZ
475 ABC
545 PQR.
loop at itab where id > 300.
write :/ itab-id, itab-name , sy-tabix, sy-index.
endloop.
My output will be :
475 ABC 2 1
545 PQR 3 2
Sy-tabix is the index of the record in internal table.
sy-index gives the no of times of loop passes.
So, for the first record in the output (475 ABC), 2 is the index of the record in internal table and as it is first time loop pass occured, sy-index value is 1.
