The Rest of Clarkdale: Intel's Pentium G6950 & Core i5 650/660/670 Reviewed

3dsmax 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:
For a 3D rendering workstation the choice should almost always be more cores. The Athlon II X3 440 is a bit faster than the Pentium G6950 here and the more expensive Core i5 6xx CPUs are easily trumped by the quad-core 750.
Cinebench R10 Performance
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.
Here we have the one redeeming quality of the dual core i5 lineup: great single threaded performance. Even the Pentium G6950 offers better single threaded performance than other CPUs way above its pay grade.
Crank up the thread count however and things go back to normal. The Pentium G6950 does better than AMD's dual core offerings, but isn't nearly as good as the X3 440.

Anand,Looks like i5-670 was dropped from idle power plot... Care to add it? :)

Yes, i5-670 idle power is missing at http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">page 8.We can find the results as 73.1W at CPU Bench here:

But the results of i5-660 & Atom D510 are really missing at CPU Bench.
Example of Atom D510 vs Athlon II X2 255, which showing no results:

Fixed and fixed :)Intel's Atom D510 is now included in Bench :)
Do you believe there's a need for the i5-660 in Bench even though we have a 661 in there? They provide the same application performance and we have no integrated graphics tests in Bench.
Take care,
Anand

Hi Anand, thanks for all the fixed. :)I agree with you about i5-660 & i5-661 both having same application performance (because no integrated graphics tests), they also having same price too.
Only power consumption will have some different, but i5-660 & i5-661 are using different OS & GPU here:
http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">i5-660 Power Consumption - Windows Vista + GeForce GTX 280
http://www.anandtech.com/cpuchipsets/showdoc.aspx?...">i5-661 Power Consumption - Windows 7 + Radeon HD 5870
If not taking much time, adding i5-660 data will make Bench even more complete & will definitely benefits readers who specifically choose 660 for some reasons.
You have really done a great job by building up this Bench function for all readers, with so much of hard works & efforts in running all the tests! Please help me remove my first reply at above which contain link code error to save the precious comments space here. Thanks & take care. :)

Thanks for adding the i5-670 idle power here!This may be a bit too much to ask, but I would really like to see the i5-6xx series idle powers measured without the high-power graphics card.
Many HTPC rigs use in-package graphics to reduce heat generation and noise, and might get left on for extended periods of time... So idle power with integrated graphics only would be a useful metric.

haha woops! fixed :)Take care,

these cpus has vtd support, diffent from i3a and i5 750, i5 661.as far as i know vtd needs also mobo support. so youll need a Q chipset.
for general use i dont think these cpus are preferable to any 4 core att similar price
gpu on the cpu is bullshit (not the idea, but the gpus are and will be), get a i3 or i5 750 and a standalone cheap card. it is obvious that these cpus are made for companies etc.
