3D Rendering Performance with 3dsmax 8 & Cinebench

We've updated our benchmark suite a bit and we're now using 3dsmax 8 with the SPECapc 3dsmax 8 rendering test. The composite rendering score is graphed below, which is the geometric mean of the rendering times in the table below normalized to a reference system.

General Performance - 3D Rendering  

The FX-74 system comes within striking distance of Intel's Core 2 Extreme QX6700 and the unreleased Core 2 Quad Q6600, which is good for performance but not so great when you take into account power consumption and cost.

Looking at the lower end FX-70, performance isn't that much better than Intel's top of the line dual-core setup, making the purchase even more difficult.

General Performance - 3D Rendering  

Performance under Cinebench is similar, however the FX-74 actually manages to take the lead away from the QX6700.

    if they decide to do anything with quad G80 chips you can pretty much guarantee that it will be for both platforms

    If they can...
    The 680a chipset has a direct HT link to each MCP, the 680i obviously can't do that and must bridge through the SPP.

    Anyway, this Quad FX is just the same thing as Quad SLI: potentially good marketing, but lackluster final performance and terrible heat and power requirements


    Now if only we could find a review that actually showed that...;)
    Seriously, the one major benefit of Quad FX is that it can run 4 GPUs. While I appreciate all of the conjecture and speculation, it isn't really a test of the facts, is it?

    How that's a benefit? You can have 8 GPUs in a same system (AMD or Intel based, it doesn't matter) with a couple of NVIDIA Quadro Plex 1000 Model II's if money isn't an issue:

    Fact: Quad SLI (7950 GX2) works on 590 SLI and 680i.
    Fact: Quad SLI (8800 GTX) does not exist.

    Until the second item changes, we only have the first to go on, which is that current quad SLI works - at least as much as it works anywhere - on both platforms. And the QSLI drivers are still largely broken - you can run benchmarks, but as soon as you start playing lots of games rather than just benching, problems crop up. Neverwinter Nights 2 for example doesn't even run properly with CrossFire or SLI, so let's not even worry about getting QSLI support for now.

    8800 GTX requies two slots, which means it won't fit in the 4x4 motherboard. Quad-SLI performance has already shown to be poor using two 7950 GX2 cards. Finally, how do you bridge four 8800 cards together?

    Huh?

    This is only when using a single MCP, the 680a uses dual MCPs.
    The 680i uses one MCP and one SPP.

    By having 2 sets of bridges (one bridge per MCP).
  • JarredWalton - Friday, December 1, 2006 - link

    Quad SLI has problems whether or not you have dual MCPs. It's driver and software related - basically the drivers don't do AFR on a lot of titles and so you end up with lower than 7900 GTX SLI performance.

    As for two slots, they're talking the width of the cards. They only plug into one slot, but they fill the adjacent slot. Quad 8800 GTX would require eight expansion slots right now. Given that Vista 8800 drivers aren't even out yet, I think NVIDIA has other things to do before they worry about moving beyond SLI'ed 8800 cards.
  • PrinceGaz - Thursday, November 30, 2006 - link

    I suppose you could replace the HSF with something smaller which would fit in a single-slot, which would have to mean water-cooling.

    Quad-SLI performance (or lack of) is probably a driver-issue.

    Don't 8800 cards have two SLI sockets therefore allowing you to chain together as many as you like (in theory)?

    It appears with win-xp sp2... this quad fx stinks. How about Win 2003 or Vista Ultimate? It might change things drastically.

    I don't think the problems in the benchmarks are not an opperating system issue. Two processors having totally four cores are not the same as a processor having the same number of cores. Additional latencies will slow down the performance.

    Actually, they probably are...Windows XP is not NUMA aware, while Vista is.

    In this case there is no difference...the Kentsfield has exactly the same latency as a 2 socket dual core because the 2 dual cores on-board don't talk directly with each other.
