ATI RX480: Measuring Performance

The ATI Bullhead has shown itself to be an outstanding performer in overclocking performance, easily matching or surpassing the best Athlon 64 boards that we have tested. But the best overclocking that we have seen doesn't mean much unless the ATI RX480 also shows stock performance that is competitive with the best Athlon 64 boards.

To determine how the ATI RX480 Bullhead compared to other Socket 939 boards, several different areas were compared.
  1. First, the ATI RX480 Bullhead was compared to performance of the Gold Editors Choice MSI K8N Neo2, which is based on the nVidia nForce3 Ultra chipset. We ran a brief series of game benchmarks on both boards to see if the ATI measured up in performance at stock speed. The ATI is PCI Express and the MSI is AGP, so the ATI Bullhead was equipped with an ATI X800 XT PCIe, and tests on the MSI K8N Neo2 were with an ATI X800 XT AGP video card. Both systems used the same 3800+ and the same 2-2-2-10 memory. Results are on page 9.
  2. Next, the performance of the PCI Express ATI RX480 was compared to the PCI Express nForce4 using the same ATI X800 PCI Express video card. A brief series of benchmarks on both boards were performed using the same FX55 CPU and memory. Results are on page 10.
  3. The performance of the ATI RX480 and nForce4 were then compared using the same nVidia 6800 Ultra PCI Express video card. The FX55 and memory were the same on both test boards. Results are on page 11.
  4. Full motherboard benchmarks were run with the ATI RX480 Bullhead using both the ATI X800 XT PCIe video card and the nVidia 6800 Ultra PCIe. These results are to establish baselines for both video cards on the ATI RX480 that can be compared to past benchmarks and to future motherboard testing. The purpose was not to compare video cards, although we suspect that the results will be used by some for comparing nVidia and ATI PCIe performance. Results begin on page 12.
Anand also did an extensive evaluation of the integrated DirectX 9 video available on the RS480 ATI chipset. He takes a closer look at the features related to ATI's integrated video. The ATI RS480 video performance is also compared to Intel i915G and the discrete ATI X300 video card. These results begin on page 16.

    I'm really excited to see another performance player in the AMD chipset market. Ironically, despite the fact that Intel is considered to have the best quality chipsets, the AMD segment has the most players and the most options. This chipset looks very good to me, especially as an overclocker, but I'm kind of left hanging in the feature set, which traditionally has been the determinant in the A64 market. Sure, 6 SATA ports is nice...etc. etc. but where's my dual integrated GigE LAN? I will take a long hard look at this chipset if SB450 comes out in time, but I think I will likely be going nForce one more generation.

    #6, of course you use an FX with the best gfx card available, he's trying to highlight small differences between chipsets. If you want P4 vs A64 look at a recent cpu review.

    However one large set of differences were the specviewperf benches? Huge differences when using ati/ati (some good and some bad) but no comments as to wtf is going on. Are those differences related to DX vs opengl, other driver issues, anybody know??

    Onboard graphics use to be not good but changed since ATi comes out with RS350...and with this RS480 DX9 VGA will be definitely good

    Currently using my RS350 playing Doom3 and still looks good :)

    I will spend my money for more HDD :)

    With DX9 included, the integrated graphics (IG) of RS480 is good. First of all, with guaranteed future OS compatibility, it's very good for the OEM - for both business machines and home-office PCs. Secondly, as stated it the review, it is good enough for high-end 2D users because of the Surround View option. Third, it is a reasonable option for gamers too, as it could serve in emergency cases, when your high-end overclocked graphic card is tired ;-(

    The IG could be even more interesting for occasional gamers and even business users if, in a thinkable upcoming chipset, the IG is involved in a SLI scheme with one graphic card. In that case the IG will add it's modest 10% to 20% to the overall gaming performance (small, but from heart). This 10%-20% could be interesting for the real gamers too, if the IG is involved in a triple SLI scheme with two additional graphic cards.

    My questions to this great article are:
    1. What about the Cool 'N Quiet operation - does it work properly on the reference board with all (DIMM etc.) configurations used?
    2. What is ATI suggesting about the SidePort - why it is limited to 32 bit and 16MB only?

    It's very impressive. But I have one minor question about the benchmarking. Why didn't you test Nforce4 + X800XT in Winstone and other benchmarks? I see, that you DID test RX480 + GF6800U and RX480 + X800XT. Maybe the margins are very small, but I'd like to see them, I think other people would like that too.

    ATI might be right in the thick of it based on performance..however...from a marketing standpoint I think they will have a tough road to plow.

    Onboard graphics makes perfect sense for non-gamers.
    If they can cram in something that works for normal desktop use, *and* can claim to support DirectX 9 as well, then it's a pretty good deal. It'll serve your needs under normal use, and it'll at least be able to run games, even if they might get an unplayable framerate.

    I'm surprised that any of you are wondering why they are producing an integrated graphics versio. Haven't you taken a walk through any of the computer superstores lately? Entry level machines from HP etc. are using integrated graphics to hold prices down yet allow users to beef up their machines when they ahve some coin later on.

    -1st of all, why does anandtech keep benchmarking AMD FX chips, sure they are the fastest hands down, but none of us are buying they. I.e. they are comparing apples to oranges, (FX vs. P4). They need to bench regular A64s!!!!

    -2nd, Onboard video still really sucks for gaming, but atleast they are making an effort, they should relize that $30 gaming cards are better quality than their onboard video and stop integrating it into their full size atx boards!!! Unless this was just a "show" board of ati's capability, then i could understand....
