Intel Sandy Bridge-E Review - Core i7-3960X and X79 Chipset Tested
Synthetic CPU and Memory Tests
SiSoft Sandra 2011
The latest version of SiSoft Sandra offers up a lot of new features including GPU performance, OpenCL, etc.
The CPU performance of the Core i7-3960X doesn't look like it will/can be challenged from a purely synthetic stand point and the memory performance numbers impress as well. It looks like adding in the quad-channel memory controller at least has a CHANCE of improving performance on software that is is any way memory bound.

Main and only reason for disabling cores in design is that in production process of chips(for example Xeon processors) they may encounter defects that with this mechanism tolerates these situations.
Defects might be the wrong word here. But they usually do it to allow the other cores to clock higher, important on a consumer product. Less important on a server environment.
The main reason i understood what that they wanted to stay within the 130W TDP envelop, plus less cores means less heat, means more OC, means more FPS.
Unless you fall in the small group of users that do programs like video encoding.
They could use this transistors for other matters,for example for cache modules, but they don't use these space for anything.With one difference This architecture is similar to Celeron processors in previous Intel designs. In this arrangement cores are deactivated instead of caches modules.Cores is disabled instead of CPU When any of them defected in production process in the factory.
When will we get some costs and build specs? Also what are the supply lines like will we have to wait awhile before wholesalers have stocks? Great Review well done.
Fell a little flat with the render tests. Could you please include something a little more contemporary eg. Cinebench 11.5 please? After all, this is going to be one of the target demographics for the processor.
Edit: Especially need an overclocked CB score. That's what people will be doing with them.
CB 11.5 scales VERY well, much like POV-Ray, and we provided an overclocked POV-Ray result, so you should be able to use that one.
Awesome review Ryan! The performance per $ still makes the i7 2600K seem like the best choice if on a budget.
Can't wait to see what the leader board looks like in Q1 2012.
;-)
Yeah, I definitely wouldn't consider this a budget part at all, even the Core i7-3930K...
I just feel that if you were to have the workloads that sb-e provides benifits for wouldn't you just get a Xeon based system.
Not if you are a small biz or pro-sumer looking to save money.
I realize that this 3960X is top dog when it comes to desktop CPUs, but I can't help it to feel a bit sad when I know there's two extra cores with an extra 5MB of cache disabled, just sitting there, doing nothing.
And it's not like it's just a certain feature that's disabled, it's two fully hyperthreaded cores! That's like a really good extra dual core CPU that's gone dark, something like an unlocked Sandy Bridge 2100K (non existant, but you get the point). It takes "dark silicon" to the next level.
Is this to preserve a certain clockspeed - power envelope ratio or is this just because there's virtually no competition in this segment anymore? Is it that much cheaper to have just one die for desktop/worstation/server?
Do I get to blame AMD for ruining my life all over again? (hint: it's a joke)
"Is this to preserve a certain clockspeed - power envelope ratio.."
You are correct right here - those two cores aren't doing "nothing"; what they are doing is allowing the Core i7-3960X to clock as high as it is.
I still agree with you though - I wish Intel had released an 8-core version with a lower top speed so we had two options at this insane price point.
Yer right Ryan about the cost when u think about it.
Ryan do you think SB-E will minimize multi-GPU microstutter? because its basically sb+2 I dont think it will but I dont know how the increased system bandwidth will minimize "jitter"
How are the single core on Blender better?? The new sb-e is the fastest single thread on the chart with 76.13 sec. Were you looking at it backwards. You may also look into using the new cycles render instead of the old Blender, as it will be the new standard in Blender 2.62 comming December.

You are correct, I was reading those results backwards. Thanks, fixed!
this CPU is a BIG FAIL!!!
$1000 and its single core performance is slower than 2600K !
Why are Review websites not slamming this CPU?
The same reason we didn't "slam" $1000 CPUs for the decade they have continued to be released. They aren't meant for single core workloads and excel really only in the outlier cases of heavy threaded workloads and the like.
No, this CPU isn't for most, it isn't even likely for MANY people, but the fact that it is there is good for the market to be pushed forward.
I don't remember anyone complaining when the Core i7-980X launched...?
$1000 Intel CPU FAIL
hardocp link
Troll...
Why in the world would anyone praise this cpu. It's a mediocre step forward from the 2600k, and with Ivy on the way in the first half of next year, a complete waste of money.
I am afraid you are going to be more disappointed in the CPU performance of Ivy Bridge than Sandy Bridge-E...
why? ivy bridge will be more cost effective for intel and us.
possibly less power and more cores. god forbid faster cores.
Because the CPU portions of Ivy Bridge compared Sandy Bridge are likely only going to be about 5-10% better.
ya i'd wait for ivy-bridge and ddr4 2012
wrong amd cpu to put against the i7 e3960x,you should be revisiting just the e3960x vs the opteron 6282se,that is the same priced cpu to go against the 3960,price for price the
3820 will be a better counter part to the 8150 or the
If I want a top end gaming pc should I go for the SBE 3960 with the ASUS extreme IV m/b with twin 580 in SLI or am I just wasting my money:(
The twin 580's sound awesome. I'd stick with a Sandy Bridge 2500K and an ASUS P867WS Revolution MoBo. You are sure not going to bottleneck with that (if you are going with just one card then go with the P8P67 PRO. Two 580's are going to draw a lot of power. 850W plus (preferably plus).
I think Ryan did a good job explaining the subtle differences between the SB and SB-E. Moreover, with AMD's lackluster Bulldozer turnout and SB-Original not offering more than 4 cores, this CPU is now the premier CPU on the consumer planet. Look, if you want TOP-end power for a while- you're not going to find it anywhere else ...
... and they're going to charge it- because they can.
Another crappy comparison.
You compare CPU's reaching 1000 euros in price (intel) vs a mere 200 euros of the bulldozer (amd).
Compare two same priced cpu's and its more of a test than this complete waste of time
