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:
As with video encoding, this sort of test greatly benefits from more CPU cores. The 661 places just below the Q9400 while the i3 parts place at or below the level of an old Q6600. All the new parts are faster than the Core 2 Duo CPUs, but that's as good as it gets.
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.
Clarkdale's saving grace is its single threaded performance. The 661 can run at up to 3.60GHz when only a single thread is active, giving it better single threaded performance than anything else on the chart here. The majority of desktop performance is still bound by the performance of a single thread. That's where Clarkdale will shine.
Even the turbo-less i3s do very well here despite their "low" clock speed. The i3 530 is almost as fast as a 3.33GHz Wolfdale and slightly faster than a Phenom II 965. The low latency L2 helps Clarkdale a lot here.
There's no substitution for more cores. Run four CPU intensive threads and Clarkdale loses its edge.
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.
POV-Ray is the worst for Clarkdale. Even the Athlon II X4 630 can outperform the i5 661. The i3s are pretty close in performance to the 661 though, they at least offer a better value.
Blender 2.48a
Blender is an open source 3D modeling application. Our benchmark here simply times how long it takes to render a character that comes with the application.
Blender is the opposite of POV-Ray, showing more of a best-case for 3D rendering on Clarkdale. The 661 still doesn't make sense based on price, but the i3 parts surpass everything except the Q9400 in this test.

The Intel G9650 doesn't exist, what You're referring is Intel G6950http://ark.intel.com/Product.aspx?id=43230">http://ark.intel.com/Product.aspx?id=43230

I've been building systems since the late 90's, mostly for others, and I'm always the last to get a decent system so I decided it was about time for me. I'm running an e6600 on a 3 yr old Intel board w/ 2g of DDR2 RAM and was wondering about the differences between C 2 quad, i3-540, i5-750 or i7-820. I priced out 3 different setups with Gigabyte boards (EP45, H57 & P55 - USB3 ver.) combined with Q8400/9300/9400 on EP45, i3-540,i5-750 and i7-820 on the H57 & P55 and 4 Gb DDR3 RAM (Crucial, Geil, Kingston)so , basically, I had 9 combinations. Excluding the i7, the price range for these builds was about $429 - $487, and I could probably do better if I tried but I was amazed that they were that close (the i7 adds another $100 but not that much improvement in performance that I can see).Looking at your charts, I think I can justify going with the i5-750. I have a decent video card for the occassional gaming that works pretty good for me now (I'll apply the $100 from above to a better card later) but I do a lot of spreadsheets and some photoshop and autocad so I think I'll see a better improvement there.
Thanks again for all your articles. Very well written, understandable and thorough.

I too am puzzled by the i7 870 scoring so low on the World of Warcraft chart -- it stood out to me immediately when I first read the article. I was a little surprised to not see it mentioned.It was suggested in another comment that this was due to the game having an issue with hyperthreading, but if that was the case shouldn't the i7 920 also have scored significantly lower than it did?

It should be noted that this new intel system does not workat 1080p/24 correct. The nvidia 9400 chipset works at 1080p/24.
So i've traded audio for skipping.
HTPC is no better off. Sad.

Previous Intel IGPs managed achieve less terrible numbers in game by cheating- they didn't render all the polygons and textures. So for good measure i require side by side screenshots of the "new, better, faster and cheaper" Intel IGP.The idea of an Intel IGP that simply isn't horrible is SOO strange that a true review would have to go the race: benchmarks, screenshots, minimum playable settings for various games and screenshots. Something the articles on HardOCP.

Why isn't the i7-860 tested in the section "Windows 7 Application Performance"?Without the i7-860 in the Windows 7 test section, this review is pointless.

I was hoping to build a new always-on home server around one of these. Power miserly IGP and idle operation (for when it's only firewalling and routing) but plenty of grunt in reserve for occasional video encoding, compiling and running virtual machines.Looks like they missed the mark for this application, and I couldn't even adopt now and wait for the real deal CPU later, as the socket is a dead end.
IMHO only the HTPC crowd have a reason to be excited here, but there are lots of other (cheaper) ways to get low power 1080p too.

Let's wait and see - There are products coming which will do gpu assisted transcoding that might shift things in Clarkdale's favor.bongbong - Tuesday, January 5, 2010 - link
I know for a fact that the athlon II x3s and x4s have to overclock like crazy in games to reach the same performance delta as their phenom II x3 and x4 brethren(coz of the 6mb cache and many games are dependent on cache)
Ive seen gaming benchmarks on anandtech where the x3 720 matched the x4 965 when they are both overclocked to 3.8ghz.
I was able to buy an x3 720 for only a 110 usd recently.
So why isnt it in the benchmark comparisons?

$150 from microcenter.
