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:
Offline 3D rendering should be another safe haven for the Athlon II X4. Core count matters and that's what AMD delivers. At $25 per core the Athlon II X4 620 is faster than even the X3 720. It's of course faster than any dual-core CPU in its price range, including the more expensive E7500. Intel's Core 2 Quad Q8200 is around 6% faster but costs 60% more.
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 is where the Athlon II X4 suffers the most. It's competitive but still slower than cheaper dual-core CPUs. This is the classic trade off for all pre-Lynnfield quad-core CPUs, you give up single threaded performance for multi-threaded performance. Luckily for AMD, Intel's Core 2 Quads suffer the same fate. While the Athlon IIs find themselves at the bottom of this chart, the Q8200 is the slowest chip here.
Turn up the thread count and the Athlon II shines once more. Again, the 620 is about the same speed as the Q8200, but slower than the Q8400. Just where it needs to be.
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.
At this point I couldn't write a more competitive position for AMD. The Athlon II X4 continues to do very well in our 3D rendering tests.
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.
Our Blender test has traditionally favored Intel architectures, and here we see the first signs of the Athlon II X4 not being able to keep up. The Phenom II X3 720 and Core 2 Quad Q8200 are both faster, but compared to Intel's similarly priced dual-core offerings AMD is still quicker.

remember that the lynnfield core i7 750 has turbo overclocking enabled so is overclocked to 3.2 ghz, which is 600 mhz overclocking, while amd processors are running at stock speedIs unfair to present the results this way, turbo is overclocking.

Sorry but your logic fails. It is a feature of the i7 750, that it runs at slower speeds when idle, as to when the processor is under load.In the same way, fan speed RPM is automatically regulated depending on whether the process is idle or under load.
The maximum clock speed of an i7 750 is 3.2gh. The user doesn't have to change or do anything. This is not overclocking in the sense you purport, and is not unfair. That is the maximum clock speed of the processor out of the box. End of story.

im sorry, but i have to defend thezorro at least this time..overclocking's basic principle is to increase CPU speeds..but if u guys look into it, what u increase is the core clock(GHz,MHz,etc) beyond the factory released specs..voltage increases and other tweaks are only done to make the overclock stable..
now,in this light,i also find it quite unfair to compare the single threaded performance of the i7s with the PII X4s..simply because the i7s can run its single core at a higher clock when the others are idle..therefore,overclocking at least THAT core..w/c of course, the PII X4s are unable to do..
i agree that the Turbo mode is a good feature, and AMD should have something like it on their CPUs..until then, the Turbo mode is kind of an unfair advantage in benchmarking single threaded performance..

Well the PII 965 is an overclocked to 3.4GHz, which is 600MHz overclocking of 920. It's unfair to present the results this way. The 965BE is so obviously OCed because it uses tons more power than the 920.fitten - Wednesday, September 16, 2009 - link
Bzzzt... wrong... when will you fanbois give this up? It's the normal and default behavior of the thing. You can do the academic discussion all you want but normal operation of the chips has Turbo enabled. To test any other way is to test a non-standard, non-default operating mode. You might as well test with the caches disabled or one or more cores disabled since those are all non-standard, non-default operating modes as well.maxxcool - Wednesday, September 16, 2009 - link

I can see both sides of this where Turbo could be considered altering the "normal" operation and also where turbo could be considered just the way it works.Doesnt bother me either way that this is put in the article, still good news from AMD.
However, since the turbo mode could be considered a supplied feature of the chip... couldnt the use of AMD Overdrive be considered a supplied feature of the newer chips? Even if it couldnt, I'd still love to see an article comparing the turbo mode to a well set up AMD Overdrive profile.

So what your saying is that the test are fair because AMD doesn't have this "turbo" mode, so all of the benchmarks are created equal?? So if the benchmarks had set up the 955/965 to 3.2 gHz (with unlocked multiplier) than you would have a favorable review??Lunyone - Wednesday, September 16, 2009 - link
Crap! I meant to say "aren't fair" in a couple of lines in my response :(SlyNine - Wednesday, September 16, 2009 - link
Turbo mode is not overclocking. Overclocking is clocking OVER factor speeds.If the CPU can increase the speed as a factory set speed. THAT IS NOT OVERCLOCKING, so get over it.
On the other hand. Go AMD. I'm still awaiting the big Core I7 killer. comon AMD you can do it.
