ATI RD580

ATI's AMD Athlon64 chipsets began with a bang almost a year ago with the "Bullhead" Reference Board. In our review of the first Radeon Xpress 200 Reference board, ATI was clearly aiming for the AMD Enthusiast. This continued with the all-white "Grouper" this past July, and the black "Halibut" which was reviewed as the Crossfire AMD in late September. Despite three generations of capable Enthusiast chipsets based on the Radeon Xpress 200 core, we only began seeing ATI AMD chipsets used in Enthusiast motherboards with the launch of Crossfire. The first ATI enthusiast board was the DFI LANParty UT RDX300 reviewed less than a month ago. Now we are finally seeing Tier 1 manufacturers like Asus, MSI, and Gigabyte with ATI Crossfire AMD boards starting to ship.

The Manta Reference board is a distinctive clear blue with Red slots and peripheral connectors. ATI seems to have no lack of Fish names or unique board color schemes, so Manta carries on a tradition that could soon stock an aquarium. Some love the fish internal development names, some hate them, but they are definitely unique.

When we recently reviewed the nVidia Dual x16 board we saw a dual chip setup with PCIe channels split between two multipurpose chips.

The nVidia dual x16 design provides one x16 PCIe off the "north bridge" or SPP and one x16 PCIe off the "south bridge" or MCP. On the AMD side the North chip is the MCP51 which communicates with the CK8 south chip over 16-bit HTT connections. The Intel dual x16 uses the same CK08 SLI south bridge as the AMD chipset, but the North chip is C19. C19 forces communications between the North and South chips to 8-bits.

The ATI RD580 also uses a North Bridge/South Bridge configuration, but all PCIe channels reside in the North Bridge and both PCIe x16 slots are driven by the North Bridge Chip. The new RD580 north supports 44 lanes and can be combined with any of the south bridges than can be used with the Rx480 chipset. This includes the ATI SB450, the revised pin-out SB460, the upcoming SB600 with SATA2 and revised USB, and the ULi 1573/1575.

ATI SB460

While ATI has used the current SB450 South Bridge in the Manta we evaluated, we expect the shipping Manta Reference Board will use the new SB460. SB460 is identical in function to SB450, with the same fast feature performance, but limited USB and no SATA2 or NCQ. It is important because it is pin-compatible with the upcoming SB600. This means boards designed with SB460 will be able to drop in SB600, with revised USB, SATA2, and NCQ as soon as this new South Bridge is available - possibly as early as January. Manufacturers can also combine the RD580 Dual x16 North Bridge with the ULi M1573, or more likely the ULi M1575, which supports SATA2, NCQ and competitive USB.

HD Audio

ULi was actually the first to annonce HD Audio on the AMD chipset in April of 2004. However, ATI was the first major manufacturer to bring High Quality HD audio to their AMD product line with the introduction of the SB450 South Bridge for the Xpress 200 chipset in the late 2004. HD support continued with the Crossfire AMD chipset. This advantage continues with RD580, which features the Realtek ALC882D HD audio codec on the Reference board.

    I believe I brought this up several times before and I'll say it again - I am personally bothered with AT's previews of reference boards. Why? Well simply because as far back as I can think it's always the same $hit. A hand tuned, tweaked to hell mobo pitted against the competing products, usually months before they go to retail and are actually available. That makes AT preview a pr piece that pretty much serves as a sales stopper against the competition regardless of which manufacturer is being reviewed. It's simply ridiculous to watch how those previewed boards always outshine the competition and show performance that barely translates into something we'll be able to experience, yet it's heralded as the best thing since sliced bread.
    Although I must give props to Wesley for not including any comparison charts in today's preview 'cause that would really tick me off.
    What ever happened to a good old technology preview? What ever happened to the good old "product taken out of the retail box" review?
    I'm not doubting AT's (in this case Wesley's) credibility or competence but the very fact that the reference board is sent specifically for AT preview makes me doubt the results. Why? Well simply because we've seen that exact scenario numerous times. These boards should be clearly marked as "AT preview edition" rather than anything else.
    So to end this little bitch session let me just say that I'll simply stop reading mobo previews at AT. Unless it clearly states it's a new mobo tech preview or has a brand and product name/code in the title of it - I'm not interested. Thank you.

    I don't get it.

    AT's preview of the Crossfire referance board was right on- performance was matched almost exactly by the DFI CF-DR. I personally would rather have the review as soon as possible, until waiting for the product to ship x units to y stores before even looking at it.

    It's good to hear that the R580, at least, is still on track. It's taken ages, but I'm glad that AT got the whole R520 delay thing cleared up. It would be interesting to find out which third party screwed ATI up.

    Personally, I'd be more interested in reading/hearing about the R530, as it should fit into my price range better than the supposed ubercard that R580 will likely be. Still good to get an update on that, though.

    On the motherboard side of things, it's nice to read that the competition is stepping up at last.
  • MDme - Wednesday, November 16, 2005 - link

    maybe it was MS that screwed things up for ATI since ATI must have used a lot of R&D for the R500 on the 360. remember that the PS3 is only using a 7800GTX at 90nm (presumably with a higher clock) ;p

    i'm glad though that the r580 is "on time" because competition is good.

    nvidia isn't the king of anything. but this is the pc world, things change and they change fast. crossifre is barely working on last years gpus, and thats just now, a year after nvidia.

    geez u know if i keep waiting for the next round, then i'll have a 10ghz 8 core cpu, with a multi-core gpu, and a multi-core ppu, with a terabyte of ram, and hundreds of tb's of storage...

    all i have to do is wait.
    and wait.
    and wait.
    and wati
    and ati = wait for us.
    don't wait for a company play with the best now, then when the best changes buy that.

    I've been having a ball since January of this year when I bought an AGP x800 xt. Nothing for me to be disappointed about.

    I think some of the comments in this thread are funny...;) I mean, nV sends out some 7800GTX 512 reference cards to review sites--cards that, when available, will cost ~$800, and consist of little more than overvolted, overclocked 7x gpus and ram, requiring a gigantic heatsink--and some people complain that ATi sends out reference boards of its upcoming motherboards to those same websites who preview them.

    Personally, I'm glad to see ATi getting so aggressive in the AMD, enthusiast's mboard markets, and could care less that they don't shove and push their products to market before they are ready. Rome wasn't built in a day, etc.

    I can well understand the angst of people who rushed to market to buy the expensive nV products on the strength of the wrong-headed idea that ATi wasn't interested in competing within this market. If I'd been rash and made the same mistake I'd be pissed, too--but I guess I'd be upset more with myself than with anybody else.

    There's just no substitute for patience, is there? It will be no trouble at all for me to wait until next year to buy a few new things. In the meantime I'll continue to enjoy the more-than-adequate gaming support the x800 xt has given me all year. I have zero complaints with it thus far. In fact, it may well be that I'm not even in a hurry next year to replace my current config.

    quote:

    People complain about ATI "releasing" products with no actual product to buy. Nvidia's so-called "reference" board can be bought in stores for $749 on the day they launched it. Quite a bit of difference there bud.
  • quasarsky - Thursday, November 17, 2005 - link

    well no difference really.

    i can't afford that lol.

    but my recent computer upgrading I WILL tell you what i can afford :) and bought :-D

    $610 =

    2 250 gig seagate sata 7200.8 harddrives $165
    2x 1 gig of patriot red heatspreader ram 2.5-3-3-8 $175
    ati all in wonder x800xt $275 (255 after rebate :-D)

    and someone bought the 7800gtx 512 mb for $749 (a pun i know cause i spent $610 lol), and then lost their job, and couldn't pay their bills and their world fell apart LOL.

    :0D

  • poohbear - Wednesday, November 16, 2005 - link

    well said mate, i love competition and really all this 7800 gtx 512mb doesnt do it for me, give me a card in the same performance group as a 6800GS/7800GS cause that's the stuff me and most ppl can afford.
