New Intel Sandy Bridge benchmarks and overclocking results! 4.7Ghz!!!

http://www.gamingaccess.com/Hardware/news/26688/New_Intel_Sandy_Bridge_benchmarks_and_overclocking_results!_47Ghz!!!
Intel Sandy Bridge promises to deliver GPU quality graphics included in the CPU. However, these graphics are not going to compete directly with mid-range or high-range GPUs, but they will finally allow Intel (which quite honestly, sucks) to enter the graphic market. Finally, laptop users won't have crappy graphic and everyone should have at least decent graphic out of the box.
After 15 years, finally I can consider this question "Do you have a graphics card?" a thing of the past. CPU should include a decent GPU right out of the box, and gamers will continue to buy their fancy Nvidia or ATI mid-range and high-end products, or even combine them in CrossFireX, SLI, or even Mix+Match using Hydra.
The Chinese website http://www.inpai.com.cn has published a review that shows that there is little to no benefit in Intel Sandy Bridge if you compare the famous Intel Core i7 875k with the new Intel Core i7 2600k
However, they were able to reach 4.7Ghz, so I don't see why they are so disappointed with Intel. Anyway, here is what they had to say about the new Intel Core i7 2600k
Conclusion
As far as overclocking is concerned, the Core i7 2600K processor reached a not so impressive 4.7GHz which is a disappointment amongst overclockers since they were the only one who's gonna pay for this CPU

Do you guys know if MSI will release a motherboard with Lucid HYDRA for the Intel Core i7 2xxx chips?
That will be sweet!

Intel Sandy Bridge Processor error

I just received my dv6tqe and read this morning about Intel replacing faulty Sandy Bridge processors that have a error. What do I need to do to ensure that my current processor isn't one of these? If it is; how do I replace it?

Reducing power consumption on Intel Sandy Bridge architecture

I know this topic has created constant chatter, but the permanence of the internet has caused some confusion with me. It seems most of the "fixes" for power drain on Sandy Bridge architecture concerns Ubuntu and it's depricated, non-vanilla kernel.
So here is what I have, and what I'm seeing:
V131 w/ Core i5 2430M 8G ram 64G SSD
Arch Linux vanilla kernel
KDE
cpufreq utils
boot options currently enabled
i915.915_enable_rc6=1
noatime,dirnoatime in fstab
I ordered my V131 from Dell with Ubuntu 11.04 pre-installed, so I have no idea what kind of power drain this thing would have with Windows installed. Right now powertop says I'm idling at 1W, which seems to be about twice what it should. enabling RC6 has calmed the fan, which ran rather schizophrenically without it.
I've read through the laptop wiki, but I'm confused as to what would work best with KDE's power management stuffs and what would be redundant.
Any further suggestions?

There is a known bug in all kernels since some point at 2.6.3X which won't be fixed in mainline until 3.3 kernel (see the Phoronix web site for more details). In my laptop (Dell E5420) it halved the battery liffe, an kept the fan at high speed, as well as the computer too hot. After some googling, yes I do managed to fix it in the current kernels also by adding these kernel parameters in grub:
pcie_aspm=force i915.i915_enable_rc6=1
Now I run the battery for about 11 hours (up from 5-6), and the fan periodically even stops (zero noise with SSD!). Talking about the battery, I also need another boot options to prevent the mouse to become sometimes veeeeryyyy slow in X window while charging the battery:
drm_kms_helper.poll=N irqpoll
Hope the "standard default" situation will improve in the future.

[SOLVED] Xorg won't start - Intel Sandy Bridge graphics

Did a fresh install of Arch on my laptop last night, looking to use the window manager i3 which I have installed but when i run "exec i3" it logs me out, indicating some sort of failure in the session. Tried "startx" and noticed that didn't work either.
"grep EE /var/log/Xorg.0.log" shows me the following errors in the log:
(EE) Failed to load module "vesa" (module does not exist, 0)
(EE) Failed to load module "modesetting" (module does not exist, 0)
(EE) Failed to load module "fbdev" (module does not exist, 0)
Extensively read the Intel and Xorg pages on the wiki and googled for an hour or two, tried to create some custom configurations for Xorg but nothing has worked so far.
It appears to be some issue with the driver in combination with Xorg. I've tried updating, then uninstalling and reinstalling the packages (the three Xorg packages + Intel driver) and specifying what driver and acceleration mode Xorg should use (intel and sna). No luck so far.
Anyone here who is having the same problem or know the solution?

Well maybe I am asking the wrong question then, because I think that might be exactly whats happening. I think maybe my problem is simply related to the window manager, i3.
Here's a link to my log anyways, if anyone wants to take a look and help me exclude Xorg from the list of potential causes:
https://gist.github.com/anonymous/f85c2a1f2a0319198a09
My original problem was that running "exec i3" gives me a blank screen followed by the login screen. I remember running "startx" at another installation I was troubleshooting and getting the very basic Xorg interface, but I dont have xterm or twm installed right now so thats probably why it's just shutting down when I run "startx".

Intel Sandy Bridge i5 2400 Vcore Range

Hi, want to check with you guys what is your i5 2400 Vcore range ? (As reported by CPUZ 1.56)
Mine keep stagnant at 1.19-1.21v between idle and load. I just know that idle vcore should be around 0.9v.
Is this normal ? My CPU frequency did downclock to 1600Mhz (100Mhz x 16) but vcore remained 1.19v.
My setting are :
Mobo - MSI P67A-C45 (Bios version 1.7)
GreenPowerMode - APS / Intel SVID (No effect)
CPU Setting - EIST enabled, CPU vcore auto, Spread spectrum on, Vdroop control high. CIE support on, Intel C state on, Power technology Custom/Energy efficient (No effect)
All other setting on auto
Despite any setting I tweak and even optimised default, the vcore remained 1.19v although clock downed to 1600mhz. Any idea ? TQ !

If your not overclocking, try disabling Vdroop, as far as I know, that should only be enabled when you overclock and put high loads on the psu, to avoid burning out cpu.
But in normal cases, I wouldnt use it.
Also disable spreadspectrum unless the pc is interfering with other signals in your house/pc's neighbourhood.

Sandy Bridge-E potential question

I am looking at a motherboard and CPU upgrade. How much more peformance do you expect from the Sandy Bridge-E series as compared to the i7-2600k? It looks as though the 4-core i7-3820 ($294) has limited overclock. However the 6-core i7-3930K ($583ish) is unlocked. Thoughts?
My system is working ok now, but I want more speed as I am beginning to work with 1080p 3D material. My current system is i7-860, evga p55 micro, 8gb, gtx 460. It performed relatively poorly on the ppbm.
Thanks

Aren't those Sandy Bridge-E chips unobtanium until sometime in late November or are they available now? I didn't think Intel had them ready for release until later this year. Can you wait that long before you rebuild?

Is a Video Card Much Better Than Sandy Bridge Integrated Graphics?

Windows 7 Pro 64bit
Does Photoshop benefit much from an Intel Sandy Bridge I2500K CPU computer having a video card?
The Sandy Bridge CPU, of course, has greatly improved on-board graphics compared to prior incarnations of Intel's CPUs.
If a video card is useful for PS, how powerful ought it be to achieve a good cost/benefit ratio, or which one is recommended? (the so-called sweet spot of price and performance)
Does it matter whether it's an AMD or NVidia type?

Do either of you two (Silent785 or Mylenium) have personal experience with a Sandy Bridge integrated GPU? Just wondering.
I have not evaluated a Sandy Bridge GPU myself.

I've found that you want a video card that scores at least 500 on this benchmark for best Photoshop performance, ideally 1000 or more:
http://www.videocardbenchmark.net/
The specific card I'd recommend right now today is a VisionTek ATI Radeon HD 6670 1 GB GDDR5, because it's a great compromise between quiet/low power operation and high rendering speed.
As an OpenGL developer of 2D graphics software myself, I can tell you that in my experience ATI makes the best structured, most stable display drivers (and are least likely to break something with a new release), followed fairly closely by nVidia. Intel has been a distant third, but one can imagine that if they're integrating GPUs on their processors now that they might better-fund a development team to make their OpenGL implementations more solid.

Intel finds Sandy Brigde chipset design flaw

Hello!
This is my first post at Apple forum, and my first post with new MBP 13''.
I was searching for some news about new MacBook Pro (2011) and I found this:
http://www.engadget.com/2011/01/31/intel-finds-sandy-bridge-chipset-design-flaw- shipments-stopped/
I am a little worried because I bought the new model of macbook pro and I'm searching for some informations about it. I have checked the Intel website and I came across this situation
http://www.intel.com/consumer/products/processors/chipset.htm
Do I have this problem? And if so how can I contact someone to help me solve this?
Should I be worried?
Best regards,
Renato Baptista

You don't have this issue. Even if you did it wouldn't affect the laptops anyway as it only affects SATA ports 3 and upwards.
From the second article:
====
Q: What is the issue?
A: Under normal operation, Intel® 6 Series Express Chipsets have an issue that may impact SATA ports 2-5. Contact your system manufacturer for more information.
====
Your laptop only has 2 ports - 0 and 1.

Intel finds errors in Sandy Bridge chipset

I just saw this announcement that Intel has found design flaws in the new Sandy Bridge chipset and it looks like there will be a recall. I just bought a Satellite A660 with the i7-2630qm which has the Intel 6 series chipset in question. What a disappointment! I guess that's the risk you take when you buy new technology. I hope Toshiba will fix this for those who already have this processor. I was thinking about returning this model anyway and now I really want to get rid of it.
Solved!

Thanks for the response, Jim, but I'd like to register my disappointment with Toshiba's decision. I *like* my new Satellite and I'd much prefer to get it fixed. I'd like to point out that a certain competitor (rhymes with 'bell') is offering a refund, replace, or repair three-option solution. Toshiba's one size fits all solution, which really only benefits Toshiba and not their customers, looks pretty poor by comparison. I hope Toshiba reconsiders.

Can I change the processor from a mac mini to a Intel Core i7-3960X Extreme Edition Sandy Bridge-E 3.3GHz (3.9GHz Turbo) LGA 2011 130W Six-Core Desktop Processor BX80619i73960X

can i and how can i change it

Julio, do you have one of the rare Minis with a socket for the CPU?
Is it...

Intel Z68 Sandy Bridge chipset and SSD caching....

For those of us considering a move to the Sandy Bridge/Z68 platform, we will eventually need to sort out whether to take advantage of the chipset's ability to "improve" ONE hard drive with a smallish (64GB or less) SSD.
Results I have seen indicate read speeds considerably slower than an SSD drive alone but acceptably improved performance over a bare hard drive. It seems like a promising situation. Capacity of a TB hard drive with read speeds nicely bumped upwards.
http://www.tomshardware.com/reviews/z68-express-lucidlogix-virtu-ssd-caching,2888.html
Question: If a user followed Harm's and other's suggestions in setting up a basic 3- or 4-drive computer, which drive should take the cheapo SSD?
Thoughts:
1) Assume the Z68 platform is loaded with all 16GB of memory that the four-slot Socket 1155 motherboard can typically accept. Would CS5 or 5.5 load enough program data into RAM to render placing the SSD on the OS drive for editing with Premiere minimally beneficial? Or would it simply make sense to put the SSD on the OS drive for so many other reasons that it's a no-brainer?
2) If it's a close call, which other drive should get the SSD? If I understand correctly, this hybrid drive won't write data all that much better. The improvement will primarily be on reads. And on that, random access reads, not sustained throughput. This is especially the case with cheaper 40GB-ish SSD's. (Some one please verify this.) Most Sandy Bridge users opting for the lower end, 20 PCI-e lanes platform won't be big-time power users. (You guys are waiting for the Socket 2011 platform.) Many of us will be getting our footage from DSLR or other AVCHD sources. AVCHD is so compressed that a single drive can supply more than enough layers for the Joe Blow amateur editor.
Unless we use Cineform NeoScene to lighten the load on the CPU, which will result in a much larger bitstream coming off the media drive for each layer, Would it make sense to help out a single drive in this situation? Or would it be universally better to set up a simple 2-disk RAID 0? Paying $65 for second drive and taking advantage of motherboard RAID 0 would seem to be a better solution if the media drive can't keep up.
For any situation, if the media drive(s) is already fast enough, would caching the media drive offer many benefits? I'm under the impression that feeding Premiere with footage is a sequential read situation, not a random access deal. Isn't the strength of an SSD in random access reads, and wouldn't the best usage be to place it on a disk that primarily is used by Premiere in random access data fetching?
3) Good grief. If it doesn't go on the OS or primary media drive supplying footage, where else? Projects disk? Scratch drive?
4) Might the most useful thing be to avoid setting up a RAID while getting some of the speed benefits a RAID 0 offers? Many casual users can build a straightforward computer but have never set up a RAID array, even a 2-disk RAID 0.
40GB SSD's are under $100 now. I suspect a lot of people will use this feature of the Z68, if the hybrid drive isn't hard to set up and is reliable. I'm curious how the Premiere crowd will make use of this feature, and will it make a palpable difference on a relatively simple editing rig? No Areca RAID cards and only 16GB memory. Nothing more than 3 or 4 single drives.

Frankly I don't see how an inexpensive SSD would help the "caching" for editing with Premiere CS5, since a typical 7200 rpm 1TB drive can perform substained writes at about 2x what a typical small SSD does.
Premiere CS5 continues to beg for lots of drives!

(one of the few "believers" in SSDs on this forum - and my "belief" is for OS and programs, not for input, media, caching, etc.)

HP PAVILION dv7-5000. sandy bridge

I just talking with Intel Technical Support Engineer and they say to me -"Marina, this design flaw with the chipset, will cause its performance (of Sata port 2-5) degrade over time, and not immediately. I would request you to contact HP for support on this. They will assist you in the correct manner, for this chipset" so what say OEM company HP?

There is a problem with the SATA II ports on the motherboards for Sandy Bridge processors. They say that up to 5% of them may have troubles in the future but going to replace all the motherboards (laptops, desktops) anyway. If your laptop has a Sandy Bridge processor, call HP or the seller of the laptop and ask them for a replacement. It's a similar issue like with the Nvidia graphics cards some time ago..
