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.
- 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.
- 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.
- 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.
- 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.

Soooo.... given the products that are on the horizon, and the holiday season, would a person be best off waiting until Q1 2005 to do a fairly comprehensive upgrade to their system... or is the stiff holiday competition and Black Friday going to be the right time to do a massive upgrade?I know it's slightly off topic, but everytime I start to visualize the right combination of parts and pieces, something new gets announced with a future ship date.... Oh well, at least my expensive hobby is still exciting.

#21I have the ATi320M in my Compaq 900z and it is good for what it is. The only thing ATi has had trouble with till now is the memory controller's performance and A64 takes that out of the mix so that ATi can really show what they can do :-) For instance,They paired a POS ALi with my 320M that makes the bandwidth, even for 2100DDR terrible. Don't know why they couldmn't use ATi's version? Must have been cheaper=par for the course.

"As you can see, the Halo score for nVidia on nVidia is about the same as our past tests of ATI on ATI. nVidia on ATI is about 3% slower than the nVidia on nF4. Far Cry continues the pattern of best performance on an ATI chipset and/or an ATI graphics card. Doom 3 and Aquamark 3 are also very slightly slower on nVidia/ATI than nVidia/nVidia, but the % change of 2% to 3% is hardly significant.The ATI Bullhead is equivalent to slightly slower with an nVidia PCIe card than an nVidia nForce4 chipset running the same nVidia card. nVidia has claimed that nVidia on nVidia is a faster combination than ATI on nVidia, but we can only conclude that these performance differences are so small as to be negligible. ATI/ATI and nVidia/nVidia are the fastest combinations in our comparisons, but the differences are so tiny that they really don't matter. You can run any of these in combination with each other without any concern that you have to match Athlon 64 chipset to Graphics chipset."
WOW! You can say that yet still push ram with tight timings despite similar small performance differences over slightly more conservatively timed but much cheaper ram?

What about sound and IDE performance? It seems you totaly ignored this! What about nVidia firewall and RAID? Does ATI do anything like that?I want ot know because I'll be buying an A64 soon and want the best motherboard.

"The RX480/RS480 is the first ATI chipset for AMD" - this is not true. IGP 320/320M was a chipset for Athlon XP, especially the mobile version was somewhat succesful.jamawass - Monday, November 8, 2004 - link
Motherboards based on this chipset would be ideal for a cheap htpc. It would have been helpful if the reviewer had looked at video decoding performance for dvd and especially hdtv. Both the fusion gold hdtv and HDTV wonder require dx9 graphics.This forces a lot of people in the htpc community to purchase dx9 cards even though they don't game, just to improve hdtv performance.Wesley Fink - Monday, November 8, 2004 - link
#14 and #17 - If you check older reviews you will see that ATI and nVidia perform very differently in Specviewperf 7.1 benches. The performance we see here is nothing unusual.We were trying to establish baselines for both PCIe cards for the future and to compare to the past. Comparing ATI and nVidia performance with Specviewperf doesn't really tell you much. Comparing ATI to ATI in specviewperf or nVidia to nVidia can be useful.
We will also be updating to Version 8 of Specviewperf for motherboard tests in the near future.

#2 - Corrected.#6 - We could have used the $1,020 3.46EE to compare to the $856 FX55, but the 3.6 P4 560 performs better in many benches. The 560 costs about $500 these days. As #14 said our goal was to compare top to top. We included the 560 for Reference. We did price/performance comparisons in our last CPU launch article.
#10 - I agree with you. The mfgs don't think ATI when they think AMD chipset. IF they look at RX480 they will change their minds, but that is a big IF.
#11 - We will do this in an upcoming nF4 retail review.
#12 - Cool'n'Quiet appears to be working properly with 2 or 4 dimms, but we did not focus on that feature. We will ask ATI about question 2.
#15 - ATI claims Gigabit PCI Express LAN is just as fast and just as cheap as on-chip Gigabit LAN. PCIe Gigabit LAN is fine, but PCI LAN can also be used with this chipset - an option the low-cost providers will probably exploit. Then again, some Tier 1 mfgs have been using PCI LAN with nForce3 Ultra to save costs.
#16 - ATI tells us the RX480 will be cheaper than the top Nforce4 Ultra chipset and more expensive than the VIA K8T890 chipset. ATI wants to underscut nVidia prices but still be a premium compared to the cheaper VIA boards.
ALL - some boards are already shipping. I have seen pics from Germany of a retail board exactly like the Bullhead except it is red. When we have more availability data we will post an update.

Anyone know what is up witht the benchmarks on page 15? They look a little strange.knitecrow - Monday, November 8, 2004 - link
what will make or break this product is the price.If mobo's based on the said chipsets are cheaper than nforce3/4 ... it can be a good budget overclocker.
No frills, just performance.
