The Dark Knight: Intel's Core i7

3D Rendering Performance
Our first 3D rendering test is POV-Ray 37 beta 29 and its SMP benchmark, the performance is measured in ray traced pixels per second:
As we've already seen, Nehalem's multi-threaded 3D rendering performance is absolutely insane - the $284 Core i7-920 is faster than the $1400 Core 2 Extreme QX9770.
Next up we have Cinebench with both its single and multi-threaded rendering tests:
Nehalem's single-threaded performance is still improved over Penryn, here we're seeing a 13.7% increase in performance at 3.2GHz.
Toss more threads at the i7 and the performance boost jumps to 34%, once again the i7-920 is faster than the QX9770.
Our final 3D rendering benchmark is the SPECapc 3dsmax 8 CPU rendering test run on 3dsmax 9:
That's another 30%+ advantage for Nehalem. If you do a lot of 3D rendering on your system, Intel is going to give you $1400 worth of performance for $284. Merry Christmas.

Umm, seems the guru3d gains are probably explained by them using a dual core core2dou versus quad core i7...Quad core's run multi-gpu quiet a bit better I believe.tynopik - Monday, November 3, 2008 - link
what about those multi-threading tests you used to run with 20 tabs open in firefox while running av scan while compressing some files while converting something else while etc etc?this might be more important for daily performance than the standard desktop benchmarks

So the low end i7s are OC'able?
what the hell is toms hardware talking about lol

Concerning x264, Nehalem-specific improvements are coming as soon as the developers are free from their NDA.See http://x264dev.multimedia.cx/?p=40">http://x264dev.multimedia.cx/?p=40.

can they do some CUDA optimizations?. im guessing that video hardware has more processors than quad core intel :PIf all this i7 is new news and does stuff xx faster with 4 core's. how does 100+ core video hardware compare?.
Yes im messing but giant Intel want $1k for best i7 cpu. when likes of nvid make bigger transistor count silicon using a lesser process and others manufacture rest of vid card for $400-500 ?
Where is the Value for money in that. Chukkle.

The x264 team has specifically said they will not be working on CUDA development as it is too time intensive to basically start over from scratch in a more complex development environment.npp - Monday, November 3, 2008 - link
CUDA Optimizations? I bet you don't understand completely what you're talking about. You can't just optimize a piece of software for CUDA, you MUST write it from scratch for CUDA. That's the reason why you don't see too much software for nVidia GPUs, even though the CUDA concept was introduced at least two years ago. You have the BadaBOOM stuff, but it's far for mature, and the reason is that writing a sensible application for CUDA isn't exactly an easy task. Take your time to look at how it works and you'll understand why.You can't compare the 100+ cores of your typical GPU with a quad core directly, they are fundamentaly different in nature, with your GPU "cores" being rather limited in functionality. GPGPU is a nice hype, but you simply can't offload everything on a GPU.
As a side note, top-notch hardware always carries price premium, and Intel has had this tradition with high-end CPUs for quite a while now. There are plenty of people who need absolutely the fastest harware around and won't hesitate paying it.

Some of us want more info.A) How does the integrated Thermal sensor work with -50+c temps.
B) Can you Circumvent the 130W max load sensor
C) what are all those connection points on the top of the processor for?.
lol. Where do i put the 2B pencil to. to join that sht up so i dont have to worry about multiply settings or temp sensors or wattage sensors.
Hey dont shoot the messenger. but those top side chip contacts seem very curious and obviously must serve a purpose :P
Spectator - Monday, November 3, 2008 - link
Wait NO. i have thought about it..The contacts on top side could be for programming the chips default settings.
You know it makes sence.Perhaps its adjustable sram style, rather than burning connections.
yes some technical peeps can look at that. but still I want the fame for suggesting it first. lmao.
Have fun. but that does seem logical to build in some scope for alteration. alot easier to manufacture 1 solid item then mod your stock to suit market when you feel its neccessary.
