BIOS Features: ATI Bullhead
It is rare that we would want to show the BIOS options for a chipset in more than basic features, but the options available to the reviewer are unusually complete on the ATI Bullhead.ATI chose the AMI BIOS, which is used by Asus and many other manufacturers on their AMD Athlon 64 motherboards.
Since the ATI RX480 is designed for qualification, you may not see the same range of tweaking options on shipping boards. However, it is worth showing some of the more interesting options from the BIOS, just so readers will know that they can be implemented on an ATI RX480/RS480 board.
Many tweaks can be found in the Advanced Menu. This includes many of the features of interest to overclockers.
As you can see, the AMD Overclocking section has adjustments for Ratios, CPU voltage, clock speed, Hyper Transport Speed, Auto-Tuning, and PCIe clock.
Memory timings and voltage are found in the Chipset, Northbridge menu.
Memory tweaks even include a User Config mode with additional memory adjustments. The Memory controls are among the best that you will ever see in an Athlon 64 BIOS.
The Southbridge controls include a range of options for the integrated peripherals...
...and a Southbridge Debug Configuration menu.
For RS480 chipsets, you will also find an RS480 menu under chipsets. Options in the RS480 allow control of the integrated graphics and graphics related options like SurroundView.
The point, of course, is that ATI supplied the ATI Bullhead loaded with the kinds of options that reviewers need to get the most out of the RX480/RS480 chipset. With a full range of options and wide adjustment ranges, we couldn't wait to see where we could take the Bullhead in overclocking.

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.SLIM - Monday, November 8, 2004 - link
#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 goodCurrently 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.deathwalker - Monday, November 8, 2004 - link
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.bearxor - Monday, November 8, 2004 - link

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.ranger203 - Monday, November 8, 2004 - link
-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....
