3dsmax 9 - SPECapc 3dsmax CPU Rendering Test
Today's desktop processors are more than fast enough to do professional level 3D rendering at home. To look at performance under 3dsmax we ran the SPECapc 3dsmax 8 benchmark (only the CPU rendering tests) under 3dsmax 9 SP1. The results reported are the rendering composite scores:
Our 3dsmax test shows an improvement, but it also shows that we're not totally CPU core bound - the performance advantage over the 975 is only 11%.
Cinebench R10
Created by the Cinema 4D folks we have Cinebench, a popular 3D rendering benchmark that gives us both single and multi-threaded 3D rendering results.
Single threaded performance of the Core i7 980X is among the best Intel has to offer today, you no longer have to choose between more cores or more frequency thanks to turbo.
Spawn enough threads and the Core i7 980X can't be touched. Performance here is 32.5% better than the Core i7 975, which itself is significantly faster than anything else on the chart.
POV-Ray 3.73 beta 23 Ray Tracing Performance
POV-Ray is a popular, open-source raytracing application that also doubles as a great tool to measure CPU floating point performance.
I ran the SMP benchmark in beta 23 of POV-Ray 3.73. The numbers reported are the final score in pixels per second.
Oh that? That's just a 47% peformance boost over the Core i7 975. This is nearly perfect scaling with core count, showing us that we're not limited by memory bandwidth or anything else. The 980X is a beast.

This wont be the only i7 6 core desktop CPU. Intel are being sneaky to milk the market. There will be another one or possibly 2 at mainstream prices. The cheapest Xeon gulftown is only $400 (2.26Ghz) so why would Intel ignore desktop when X58 boards will happily run a Xeon?GourdFreeMan - Thursday, March 11, 2010 - link
That strategy could just as well backfire on Intel. If you have to wait six months for the other hexacore desktop Gulftowns, you might as well forgo Gulftown entirely and wait a year to fifteen months for hexa/octocore Sandy Bridge. The new AVX instructions in Sandy Bridge are likely to have a far broader impact on performance in terms of software anyway...Triple Omega - Thursday, March 11, 2010 - link
Well I hope you're right. As right now it looks like even Sandy Bridge releasing at least 26 months after the 920 will still have only 4 cores maximum. Not much of a replacement.Also, did anyone notice they broke their own Moore's-Law rule? The 980X only has 1,6 times the transistors of it's predecessor.

"Also, did anyone notice they broke their own Moore's-Law rule? The 980X only has 1,6 times the transistors of it's predecessor. "You have a fundamental misunderstanding of Moore's Law, this is not unexpected because it is often misquoted or misrepresented in the less technically oriented press. The proper way to state Moore's law is the transistor count will double roughly every two years for the same die size, or for the same transistor count the die size will half. Yet the best way is to simply say the transistor density (transistor/unit area) will double.
You can check the 32 nm adherence to Moore's law by following up on the technical presentations that float around the web, Intel published their IEDM 2009 32 nm stuff:

See the scaling for gate pitch or SRAM cell size slides 5 and 6, they are clearly falling right on the Moore's law path.
This is not by accident, a linear scaling factor of 0.7 when squared is 0.49 or roughly 0.5 i.e. half the area, this factor is chosen to get double the transistor density each technology node.

"Moore's Law" refers to density, not actual transistor count. Anyone can build a big chip.tterremmotto - Thursday, March 11, 2010 - link
Actually, Moore's law has nothing to do with density nor speed. It was about price.Moore's "observation" simply stated that the price per transistor halves every 18 moths. Wether that is due to density increases or process advancement is not a necessity.
Never an observation has been so misunderstood, and yet have such a fantastic side effect.

Actually, Moore's law is all about transistor density. I know. I see it everyday in the halls, in the elevator, at my desk, in the cleanroom. . .JumpingJack - Thursday, March 11, 2010 - link
He has a small point, Moores Law is just an obseravtion of the rate of shrinkage over time, the phenomena is driven by the economy of scale.Jack

where are you getting your xeon pricing info from?all i can find from any solid source is the current xeon quad core processors which are running about $2000 on newegg at the moment.
xeons have always carried a premium for the intel dual processor support, and imho, a cheaper xeon is going to be more "enterprise" oriented and not be a real upgrade for the home x58 platform.
again, this is pure speculation, but i think we are going to be stuck with our current i7 stuff until intel decides to do a 32 nm refresh on the home line up.
basically, what i'm trying to say is that i think any xeon capable of creaming an i7 930 is going to be WAY more expensive than the 980x gulftown on display here.
