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.

3dsmax r9 - SPECapc 3dsmax 8 CPU Test

The 1075T comes close to its competitors in the 3dsmax test, while the Phenom II X4 970 definitely falls short.

The quad-core Athlon II X4 645 does much better than the dual-core i3 530 (and by extension the 540). The same holds true for the Athlon II X3 450 vs. the Pentium G6950.

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.

Cinebench R10 - Single Threaded

Single threaded performance is AMD's weakest point. Even at 3.5GHz the Phenom II X4 970 can't keep up with a turboed Core i5 750. If you run a predominantly single threaded workload, Intel will typically offer you better performance than AMD.

Cinebench R10 - Multithreaded

Turn up the thread count however and the value proposition shifts to AMD. The Phenom II X6 1075T gives you more for your money in a heavily threaded app than the Core i7 860, and the Phenom II X4 970 is a smidge ahead of the i5 750. The Athlon II X4 645 and Athlon II X3 450 both do very well.

I've started running Cinebench 11.5 in preparation for an update to Bench, some of the initial results are below:

The default benchmark is heavily threaded. As a result the scores echo what we just saw.

    I would really like to see a "Bang for your Buck" graph. In many test, AMD comes close to the i7, but the i7 cost more. So when you do a performance per dollar ratio, AMD may come out on par, or maybe even ahead in some cases.

    I also find it interesting that some of the Phenom II x4's have a lower power consumption at idle than the X2's. I realize the X2's use the same silicon, but with the cores turned off, shouldn't they use less?

    Great over all article as always though :)

    Anand, as always great work,

    You write "Bulldozer is out of the question however, AM3+ chips aren’t backwards compatible with AM3 motherboards (although the opposite is true, you will be able to use your 970 in an AM3+ motherboard)."

    Is this the definitive truth? :-)

    I have read a lot of people guessing whether AMD will have AM3 compatibile Bulldozer modes available, or only AM3+ (AM3Rev...).

  • Anand Lal Shimpi - Tuesday, September 21, 2010 - link

    This information came directly from AMD :) Not saying it's 100%, just saying it's the source.

    You'll see AM3+ motherboards in advance of the Bulldozer client launch so you'll be able to buy a new board for your CPU and then later drop in a Bulldozer.

    Take care,
  • stmok - Tuesday, September 21, 2010 - link

    Yeah, its true.

    Bulldozer isn't backward compatible with current Socket AM3 motherboards.

    But Socket AM3+ motherboards will be backward compatible with existing AM3 processors.

    Mentioned on a number of sites...

    => http://www.extremetech.com/article2/0,2845,2368186...

    "AMD also told us that it will introduce a new AM3+ socket for consumer versions of Bulldozer CPUs. AM2 and AM3 processors will work in the AM3+ socket, but Bulldozer chips will not work in non-AM3+ motherboards."

    => http://www.rage3d.com/articles/amd_heat_vision_hot...

    "For the desktop, the Zambezi processor is good news and bad news. The good news is it's an 8 core product, the bad news is it needs a new socket - AM3r, or AM3+. This is an electrical upgrade of the AM3 platform, to provide the power phases and planes/states required by the power gating features of Zambezi. As you might have guessed from the name, this socket is backwards compatible with existing AM3 processors, so you'll be able to piecemeal your upgrade - motherboard for your birthday, CPU for Christmas, or however your upgrade cycle works."

    => http://www.xtremesystems.org/forums/showpost.php?p...

    "When we initially set out on the path to Bulldozer we were hoping for AM3 compatibility, but further along the process we realized that we had a choice to make based on some of the features that we wanted to bring with Bulldozer. We could either provide AM3 support and lose some of the capabilities of the new Bulldozer architecture or, we could choose the AM3+ socket which would allow the Bulldozer-base Zambezi to have greater performance and capability.

    The majority of the computer buying public will not upgrade their processors, but enthusiasts do. When we did the analysis it was clear that the customers who were most likely to upgrade an AM3 motherboard to a Bulldozer would want the features and capability that would only be delivered in the new AM3+ sockets. A classic Catch-22.

    Why not do both you ask? Just make a second model that only works in AM3? First, because that would greatly increase the cost and infrastructure of bringing the product to market, which would drive up the cost of the product (for both AMD and its partners). Secondly, adding an additional product would double the time involved in many of the development steps.

    So in the end, delivering an AM3 capability would bring you a less featured product that was more expensive and later to market. Instead we chose the path of the AM3+ socket, which is a path that we hope will bring you a better priced product, with greater performance and more features - on time.

    When we looked at the market for AM3 upgrades, it was clear that the folks most interested in an AM3-based product were the enthusiasts. This is one set of customers that we know are not willing to settle for second best when it comes to performance, so we definitely needed to ensure that our new architecture would meet their demanding needs, for both high performance and overclockability. We believe they will see that in AM3+."

    <i>But Socket AM3+ motherboards will be backward compatible with existing AM3 processors.</i>

    This was not true from AM2+ to AM3, and I don't believe for a second this is true across the board from AM3 to AM3+. Many motherboard manufacturers (even top tier ones) will not bother with BIOS updates to older boards that went EOL some time ago.

    If your board has a 7xx or Nvidia chipset and has been EOL for a year, I wouldn't count on anything. Better safe than sorry.

    "This was not true from AM2+ to AM3, and I don't believe for a second this is true across the board from AM3 to AM3+. Many motherboard manufacturers (even top tier ones) will not bother with BIOS updates to older boards that went EOL some time ago."

    From what I read, it is not the same situation before: Most AM2+ boards can run AM3 cpus, pending on BIOS support, AM2+ cpus will not work on AM3 boards, because they do not have a DDR3 memory controller. AM3+ (AM3r2) cpus will not work on AM3 boards, because the power gating logic on Bulldozer based cpus is not compatible with the power plane setup on AM3.

    Basically, AM3 cpus are both backwards and forwards compatible with previous and upcoming sockets in their line.
  • Dark_Archonis - Tuesday, September 21, 2010 - link

    Yes, for AMD owners, the party is over. Bulldozer is not compatible with AM3 motherboards, so anyone who wants Bulldozer will need a new motherboard.
  • Madmanden - Wednesday, September 22, 2010 - link

    The party's over for both AMD and Intel users. They both have to get a new board for upcoming CPUs.
  • mike23 - Thursday, September 23, 2010 - link

    this is a very good point.

    Benchmarks that cover something more than common tasks (that low and mid range processors do adequately every day) would be helpful.

    With regard to the competition issue...It's blatantly obvious where Intel sees AMD as competition. All the way up to the 4 core I7 series. Beyond that, no competition and ridiculous prices.

    If not for AMD's efforts, you wouldn't have the I5's and I7s in the 200-300+ range right now. So, yes, they are providing strong competition in certain market segments.
  • DMisner - Tuesday, September 21, 2010 - link

    Would you consider doing something of a Folding@Home benchmark, possibly running the SMP client for a day or something and seeing what kind of PPD figures you would get with these processors?
    Seems like F@H is really what I do most with my computers.
