The Core i7 980X Review: Intel's First 6-Core Desktop CPU

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.

[QUOTE]With up to 6 cores running at 3.46GHz, Gulftown is not only the fastest CPU in Intel’s lineup, it’s also the fastest quad-core Intel makes.[/QUOTE]I think you meant to say it's also the fastest "single-core" Intel makes.

And for only one thouuuuusand dollars! What a deal!!
lol yeah, anyone who spent $999 on an X58 CPU can now spend $999 on a new cpu 18 months later. $2000 for two CPUs in the course of 18 months. How you can spin that as being a good thing boggles the mind. What a waste!

Well, maybe you spent the ~$280 or so on a 920 in November 08, which you could now upgrade to the 980X if you wanted. Considering Intel's past history of supporting new processors on older motherboards (see, for example, P965 and Penryn) it is nice that this is supported, even if the upgrade is extremely expensive.BelardA - Thursday, March 11, 2010 - link
Kinda sad and funny... when core 2 came out, it destroyed the P4 line and of course kicked AMD down bad.Even todays $65 intels and $45 AMDs (running about 2ghz) are still faster than those older Pentium EE chips. And what was sadder back then was that even AMD's $200 CPUs were still faster than the $1000 intels... unless your were doing 3D work and encoding video.
*sigh*
Thanks to intel's back-room deals with the major PC companies, the illegal activities has hurt competition. AMD is doing better today, but have little to work with. And we see what the lack of competition does such as ATI vs. Nvidia.

Why they keep the CPU frequency so high? All consumer quad cores go higher than 2.5GHz??? I really like Opterons, low frequency with more cores.Seriously I hope Phenom VI (I made it up, they may call it something else) could have a model of 6 cores with each running 1.2GHz.
My own usage is mostly programming in JEE + documentation, so I need more cores but not that fast, so I could save a few bucks on my electricity bill in a year. :)

You can always underclock/undervolt if you don't need the performance from the extra speed but want the power savings.Note that this is the "Extreme" version, so it makes sense to have the fastest speeds possible. The mainstream versions that are coming will probably have lower clock speeds.

Maybe I missed it - but would this have any predicted implications on the 920 price over this year span?I'm rebuilding a rig a component at a time and Im wondering if there would be much variance if I picked a 920 now or in Q4

"The first Core i7 did not power gate its L3 cache, Lynnfield added it and Gulftown has it as well."THANK YOU ANAND!!
No wonder this is my #1 favored site. :D

I don't know about anyone else, but I would have liked to have seen how this chip fares to overclocks of Intel's other Core i7 series. While I'm sure many people don't bother overclocking, I would wager that most people who visit this site do, and probably bought into the Core i7 920 series and overclocked it to 4 GHz or more. While I'm sure the Core i7 980X is a beast, I'd be more interested in seeing how it fares when overclocked parts are taken into account, because personally I see very little reason to make the jump from the 920 to the 980 after this review. 2 more cores are nice, but not when they are slower.B3an - Thursday, March 11, 2010 - link
Anand, can you please include newer software for some benches. For instance you are still using 3DS Max 9 which was released in 2006.The latest is 3DS MaX 2010 (version 12).
I only ask because i'm sure that anyone who can afford this CPU can ceratinly afford the latest 3D rendering/modelling software. And besides that they might have better support/performance for these type of CPU's.
