The Sandy Bridge Review: Intel Core i7-2600K, i5-2500K and Core i3-2100 Tested
by Anand Lal Shimpi on January 3, 2011 12:01 AM EST3D Rendering Performance
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.
At the risk of sounding like a broken record, we have a new champ once more. The 2600K is slightly ahead of the 980X here, while the 2500K matches the performance of the i7 975 without Hyper Threading enabled. You really can't beat the performance Intel is offering here.
The i3 2100 is 11% faster than last year's i3 540, and the same performance as the Athlon II X4 645.
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 sees a huge improvement with Sandy Bridge. Even the Core i3 2100 is faster than the 980X in this test. Regardless of workload, light or heavy, Sandy Bridge is the chip to get.
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.

Looking at the results of Quick Sync transcoding, the results are very interesting.But which h264 encoder is ArcSoft using, im guessing its Mainconcept, would like to compare QS with x264 to be sure of the results.
In future, be nice to see the original frame to compare with too. Without the original, comparing just the encoded frames means little.

Looking at cbscores.com (using the actual Cinebench 11.5) the 2600K is not THAT glorious at rendring-speed ... Why did you use Cinebench 10?pshen7 - Tuesday, February 22, 2011 - link
Who in the world named it Sandy Bridge? And Cougar Point is no better. They need a better marketing department. Seriously.Peter Shen, Koowie.com

does that mean I can't install windows XP/DOS on UEFI motherboards?dwade123 - Tuesday, March 8, 2011 - link
Intel i3 2100 is so underrated. It beats AMD's fastest's 6 core and older i7 Quadcores in many games and is only a little slower in other areas.Wouggie - Tuesday, March 15, 2011 - link
With an even improved i7990 Extreme now out, with a base speed of 3.46 GHz, which would be the better choice, considering I am going to using a dedicated graphics card Nvidia Quadro 4000.Also. what do you see on the horizon for three channel motherboards with more than 2 SATA lll 6 Gb/s connectors?

The benchmarks against the AMD processors are useless. All the compare is core-to-core performance (4 core to 4 core). You should be comparing is comparably priced processors/systems. For example, the 6-core AMD 1090T costs a hundred dollars less than the i7 2600 at newegg.com, yet your benchmarks fail to provide any comparative benchmarks. It's quite possible that for some applications, that the 6-core AMD may perform better than the more expensive i4-core 7 processors in your benchmarks.scurrier - Friday, April 1, 2011 - link
Anand says, "frequency domain (how often pixels of a certain color appear)," but this definition of the frequency domain is incorrect. Frequency domain in the case of video is a 2 dimensional discrete cosine transform of the frame. It is not a count of pixels like a histogram (binning) or anything.aka_Warlock - Saturday, April 30, 2011 - link
Would be nice to see som test of how much of a performance difference lacking VT-d has on th CPU?AbdurRauf - Monday, May 2, 2011 - link
Does the QuickSync handle uprezing or only transcoding? Have you looked at the new WinFast HPVC1111 SpursEnginex4 and compared it to Quicksync, Cuda and Stream encoding and uprezing?
