ATI's RV530 aka Radeon X1600

Targetting the upper midrange is the Radeon X1600 (RV530), built on the same 90nm process as the Radeon X1800 (R520). All of these RV530 series and lower are single slot products, according to the roadmaps.

ATI RV530 Roadmap
Card Pipes Std Core Clock Std Memory Power Consumption
X1600 XT 12 600MHz 700MHz 60W
X1600 Pro 12 500MHz 400MHz 40W

Radeon X1600 will actually be very similar to X1800LE, but with a smaller internal bus (256-bits) and a smaller memory bus (128-bits). The X1600 cards also have H.264 support like the R520 series.

Like X600, there will be many vendor dependent options for the cards. The configuration roadmap allows for DDR1, DDR2 or GDDR3 in both the XT and Pro cards, with memory sizes ranging anywhere from 128MB to 512MB. In fact, we even have claims from one manufacturer that they will produce 64-bit versions of the card en masse; so potential buyers will need to be wary of buying Radeon X1600 Pro cards with the smaller bus (like with the Radeon 9800SE). Another noteable is the support for HDCP and HDMI on many cards. Also, like with the GeForce 7800 series, vendors are allowed (perhaps even encouraged?) to bin chips for higher clock speeds. We've received reports from AIBs that some RV530 Pro cards will ship with 525MHz clock speeds even though the roadmap indicates 500MHz is the standard configuration.

Perhaps one of the more interesting aspects of RV530 is the low power consumption. Reference 64-bit boards of RV530 using GDDR3 at 500MHz core clock speeds have a power consumption of just 25W. 128-bit boards were estimated at 40W and X1600XT boards with all the goodies were estimated by AIBs to be 55W.

    Actually, you missed a few:
    X850 PRO
    and I think there's also an X850LE/SE somewhere (it's an OEM).

    You mentioned the X800XT twice. :P Reply

    well, see, it just goes to show how many cards there are and most of them didn't come out until after the initial release. It also shows how many cards there really are and how confusing it is regardless if you're informed or Joe Six Pack Reply

    i never heard of the X800LE Reply

    There is a X800LE, friend of mine got one. Cant say I've seen many being sold though. Reply

    Well, you have to realize that at first, the GT, GTO, XL and X850 series didn't exist. So, at the release of the R420, there was the X800, Pro, XT and XT-PE. Cards like the LE, GT, XL, and X850 were released later to fill in gaps in the market. Give it some time ^^ Reply

    the X800SE came out close to launch, the X800 came out at the same time as the XL Reply

    I can't wait to see how these cards stack up to their equivalently priced nvidia parts. The most I've ever spent on a video card was $350 for a geforce 2 ultra 64mb ddr, and I doubt I'd go higher than that ever. I love having the fastest card available, but it seems like that's no longer a possibility for me. Makes me sad, maybe one day ATI and nVIDIA will stop being so greedy and price their cards more sanely. Or maybe they will give me a free one because I'm better than everyone else at everything...... (yeah that includes you a$$hole) Reply

    Bottom of page 1: "R580 is essentailly a clock ramp and pipe ramp of R520, but both of those details have not been disclosed yet (even to AIBs)." So no 24-pipe part? Disappointing....

    So no 24-pipe part?

    I don't think you understood. A pipe and clock ramp insinuates that there will be more pipes in the R580. It'll probably be a 24 pp GPU. Roadmaps disclosed that the R520 would be a four quad (4x4=16) GPU and the R580 would be a 6 quad (6x4=24) GPU.

    Does anyone know how many vertex pipes the R520 has? : ( I can't remember where, but I think I once saw it would have up to 10 vps. Is this true? You'd think 8 VPs working at 600MHz would blow the G70 out of the water in terms of vertex processing power. I need to do more research regarding GPUs. Does anyone have any good references?
