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.

    Good job Wesley and Anandtech staff, very nice article! Thanks for answering all the questions Wesley...

    Things are really heating up for AMD64 chipsets... I might just have to wait for Q1 2005, but then dual core CPUs will be the rage of rumor and HL2 is right around the corner ARGH!!!!!!

    I might just bite the bullet and pull the trigger on an AMD64 3500+ with a Nforce4 or ATI chipset this holiday season because I really can't run HL2.... I cannot continue to wait for the next best thing. I have been waiting to upgrade since dual DDR was just a rumor... LOL!

    Are these going to be shipping mainly for s754 or s939? I think determining factor will be price, cheaper than nforce 4 ultra? isnt that going to be $150+? I think they need to get closer to $100 for any serious challenges..

    I don't know, I still want Tyan's new dual Opteron with dual SLI board.

    Nice article. But I'm afraid, like the out-standing SiS ref board, these may never see light of day but in budget off brand products like ECS, FOXCONN, MATSONIC etc nVidia just seems to dominate the enthusiast sector.:(

    #29 - A new Sounthbridge, called SB450, is due to debut the first of the year. It will feature High-Definition audio and other updates.

    RAID - Here is the reply from ATI regarding RAID on the Rx480/SB400:
    "Your Raid answers are as follows:

    Our Raid implementation will support up to 8 SATA devices. This is limited by ODM implementing appropriate amount of SATA channels on pcb.

    1) Currently SB400 supports RAID on SATA, not on IDE (PATA).

    2) IDE cannot be combined with SATA in RAID. Limited to SATA only.

    3) We only support RAID 0 and RAID 1.

    4) We do support hot swap for RAID 1. We can replace the failed hard disk and rebuild a new driver in RAID 1"

    The review will be updated.

    Here's a hardware question for you folks. Given that SLI is becoming more and more of an option, I'd like to know if the scenerio I thought up can be possible. Also, a general question is "What can a HyperTransport link be used? Is it specifically a link from CPU to north/south-bridge or is it a general link for general access?"

    The above question will basically determine if the scenerio I thought of is possible. Basically have a HT link big enough for an additional chip where it supports additional PCI Express lanes for 1x, 2x, or 4x slots. I see current chipsets designed with 20 lanes, or in ATi's case 22 lanes, and it got me to wondering if such a scenerio is truly possible that a full dual 16x instead of dual 8x can be a reality. If you can explain or answer this, that'll be great.

    The main problem of the ATI chipset will be the compatibility of south bridge ... Their south bridge sucks and that's why some of the RS350 motherboard use ULI south bridge instead of their solution ...

    http://techreport.com/reviews/2004q4/radeon-xpress...

    You can check with the USB performance ... That can be called the most worst that I have ever seen ... And we still do not know if there is any compatibility issue of the USB interface unless there is a lot of ATI chipset based retail board hit the market …

    And a preview board of chipset vendor is nothing important ... Where is the highly phrased SiS 755/755FX chipset based and good quality motherboard we can buy ? Sometimes there is something inside the chipset that we can reveal from the demo board if all the motherboard maker does not have the solution …

    Anyway , time will tell …

    #27 I doubt ATI is doing that. If the mobo's that ship are noticealbe different (performance wise) from the one's ATI are sending out for review, I know that there will be a huge backlash from the hobbyist community and ATI knows this.
  • blckgrffn - Monday, November 8, 2004 - link

    Is no one else suspicious that ATI shipped out hand picked, thouroughly tested MOBO's that may not be representative of shipping boards? I will wait until I see a review of boards using this chipset in the future before I make up my mind.

    Wow...ATI really stepped it up with their new chipset and integrated graphics solutions. This chipset should really give nVidia's NF4 a run for it's money. Also I agree w/#22...let's see some HDD performance benchies and what about an integrated software firewall or on-board RAID controller (article says similar to NF4's "Any-Drive")...how do these components compare to NF4's or does ATi's chipset even have them.

    I know I was skeptical about ATI coming out with an A64 chipset, but they've really gone above and beyond what I've expected with their "first" board. I am VERY impressed with their OC'ing performance.

    I don't want to say that this new chipset is the best thing since sliced bread (I'm sure nVidia has a response to ATI's chipset in the works), but when it comes time to buy my 90nm A64 rev E0, ATI looks like they might have my business/money/whatever the hell you want to call it ;D.
