3D Rendering Performance

We've moved on to using 3dsmax 9, which allows us to run a 64-bit version of the program for our tests.  The test scenario is still made up of the CPU rendering tests of the SPECapc 3dsmax benchmark.  We report the rendering composite, which is simply the geometric mean of render times across seven benchmarks normalized to a set of reference scores.  We ran 3dsmax 9 using its Direct3D driver given the poor state of OpenGL performance under Windows Vista. 

3dsmax 9 64-bit  

3D rendering performance under 3dsmax has proven to be one of many strong poitns of the Core 2 lineup, and the trend continues here under 64-bit Vista.  The E6700 outperforms the newly released 6000+ by just over 15%, with the E6600 and E6400 following suit. 

Lightwave 3D 9.0 is available with 64-bit support, giving us another 64-bit 3D rendering test.  We looked at performance under two scenes that ship with the program: Dirty_Building and Record_Player.  We measured the time it took to render the scene in seconds, lower numbers are obviously better.

Lightwave 3D 9.0 64-bit  

Lightwave performance is far closer between the contenders, as the E6700 and 6000+ are basically tied in our first benchmark.  The same is true for the E6600 and the 5600+, while the 5000+ is actually slightly faster than the E6400.

Intel gains a little more of an advantage in our next test scene, but the numbers continue to be quite close.  If Lightwave is where you spend most of your time, AMD seems to be quite competitive with Intel here. 

POV-Ray's ray tracing benchmark has been a popular CPU test for quite some time, and we turn to its 64-bit SMP beta to stress the CPUs here today:

POV-Ray 3.7 64-bit

Performance is extremely close between the Core 2 and Athlon 64 X2 families, there's no clear winner here although once you get down to the E6400 the X2 5000+ becomes a bit better of an option.  

Our final 3D benchmark is the 64-bit version of Cinebench 9.5, a fairly popular 3D rendering benchmark due to its ease of use and quick runtimes.  We ran the multi-threaded CPU rendering test and reported the final score in CBmarks.  Higher numbers are better:

Cinebench 9.5 64-bit  

The Cinebench results are further cause for celebration for AMD, performance is higher on the green side of the fence at each price point we targeted for this review.

    I just changed FSB from 266 to 350, I have a 2.8Ghz C2D.
    Wow, no shit? That IS easy.

    You think that's easy...

    I've got 2.4GHz E6600 on an nForce 680i-based Asus P5N32ESLIWTF board (I forgot the model nubmer, can you tell?).

    Last night as I was disabling the onboard audio, in the BIOS, I was curious so I went to the "extreme tweaker" menu, hit "AI Overclock", selected "20% overclock", and there you go - a 2.88GHz E6600.

    The machine's fast enough to run everything I want at stock speeds, but who's going to complain about spending 15 seconds to bump the clock speed by 20%?

    I would like to point out that overclocking S939 and AM2 chips is equally easy-and probably why C2D overclocking has proven easy for many people-they started on the AMD chips when they were king and very overclockable (50-60% is not uncommon on the low end AMD chips).
    For example, my main rig is still an Opteron 165 (basically an X2 3800+ with twice the cache) clocked at 2.7ghz, no voltage change, stock cooling, raised FSB speed from 200 to 300mhz. Required MAYBE 5 bios boots total, all of which were concerned with ram stability (switched ram to 2x1gb at same time installed processor), which can be a pita with a DFI Ultra-D.

    The difference between AMD and Intel when it comes to overclocking: highest possible speeds. C2D has A LOT of headroom, which means E6300 AND E6400's can usually reach >3ghz, topping out around 3.5ghz; E6600's can be pushed to 3.7ghz. X2 3800's commonly top out at 2.6gh. Stellar chips can be pushed to 3ghz (actually, good Opty's normally reach 2.8-3ghz, very few X2 3800's get there). No AMD cpu I've seen online has been pushed to 3.2ghz or greater on air. This means C2D is king for now, when we are talking about overclocking.

    You are right about Conroe but actually single core AMD CPUs reached 3200 Mhz with air cooling. And some Opty 165-170-175s managed to exceed 3Ghz Barrier with low voltages. Here is an old thread about San Diego:

    The whole time I was seeing how the X2 6000+ stacked up against the E6600, which would be the CPU I bought if I go with Intel. And suddenly I get to Power Consumption and it's mysteriously absent. I suppose I can try to extrapolate based on the other chips, but if you have data for it and accidentally omitted it, can you please add it in, for the sake of my laziness? Thanks!

    i found it interesting the 6700 consumes less power than its younger brothers. But wow, this article made a 6600 really look awesome

  • JarredWalton - Tuesday, February 20, 2007 - link

    Not sure why E6600 is missing on the power charts (perhaps Anand was running a downclocked E6700 for performance testing, which wouldn't be valid in power numbers), but it's pretty safe to say the E6600 would be right around the power draw of the other C2D chips - between the E6700 and E6400. Voltage settings also vary on the C2D CPUs IIRC, so you can get some CPUs that run at 1.1V and others that run at 1.3V, even though they're the same model number.

    Is the author making a hint of 'things to come' when Barcelona arrives?

    A thinly veiled hint that AMD could actually compete? One can only hope. As was said repeatedly in the article, competition is the reason we have these prices and these processors. Without competition I doubt we would be seeing the performance, let alone the price, that we see today
  • hubajube - Tuesday, February 20, 2007 - link

    The X2 5600 does actually compete well with the E6600 and they're very close in price. Although, OCing is another story.
  • goinginstyle - Tuesday, February 20, 2007 - link

    I was expecting to see another "just like me" article on this CPU and was surprised to see benchmarks under Vista and 64bit at that. Thanks for an interesting read and hopefully the motherboard editors will start using Vista in their articles now.

    I still think AMD is close enough in performance that it does not matter that much which platform you use. After all of the troubles I had with my 965 board I wonder why I switched now. Was there any reason why you did not use the nvidia 680i board for testing since the 590 board was used for the AMD system?
