ATI's RV515 aka Radeon X1300
ATI's internal roadmap reveals that the RV515 (X1300) is the follow up to RV370, and will come in three main variations with several HyperMemory options and differing core clocks as well. Our previous roadmaps have revealed that RV515 is exclusively a single quad design, with memory interfaces from 32 to 128bits. Even the low end RV515 cards will utilize some form of H.264 decoding and/or HDCP support, making these cards extremely attractive for DVR machines.

ATI RV515 Roadmap
|
||||
| Card | Pipes | Std Core Clock | Std Memory | Memory Width |
| X1300 Pro | 4 | 550MHz | 500MHz | 128-bit |
| X1300 LE | 4 | 450MHz | 400MHz | 128-bit, 64-bit |
| X1300 LE HyperMemory | 4 | 450MHz | 500MHz | "64-bit" |
HyperMemory versions of RV515 will utilize a 32-bit memory bus, but since they utilize the system memory they use a different system of determining the "Supported Memory" configurations as follows:
|
HyperMemory "Supported Memory"
|
||||
| Card Memory | System Memory | "Supported Memory" | ||
| 32MB | 256MB | 128MB | ||
| 64MB | 256MB | 128MB | ||
| 128MB | 256MB | 256MB | ||
| 32MB | 512MB | 128MB | ||
| 64MB | 512MB | 256MB | ||
| 128MB | 512MB | 256MB | ||
Wrap Up
Among other noteables in the roadmap, some of the more prominent features of R520 included HDMI over Silicon Image's WALDO interface -- all other cards in the roadmap that feature HDCP but not HDMI will use TI's TFP513PAP. On low profile RV530 cards, HDMI connectors are supported directly on the PCB, while analog and DVI connectors are attached via a ribbon cable to a daugther card. For users looking to set up a cheap TV-only DVR, the daughtercard is completely optional - saving money and space.
In the roadmap we also saw some new SKUs from the X550 line and X600 line supporting HyperMemory. With NVIDA's quasi-TurboCache GeForce 6500, an X600 HyperMemory card could put a real advantage of low end video processing back in ATI's court.
X800GTO is also going to be hitting the shelves soon with street prices of $159 for the 128MB version and $179 for the 256MB version. You might want to check our previous roadmap on this particular product, since everyone (including ATI) expects a sub $200 12 pipe R420 to really become the de facto midrange option. A low volume sixteen pipe version will show up for select vendors in select regions.
We go under NDA in the near future for many things ATI, so get ready for AnandTech's upcoming coverage come launch time!

Actually, you missed a few:X800
X800GT
X800GTO
X800PRO
X800SE
X800LE
X800PRO
X800XL
X800XT
X800XT
X850 PRO
X850XT
X850XTPE
and I think there's also an X850LE/SE somewhere (it's an OEM).

You mentioned the X800XT twice. :Pmistersnail - Wednesday, September 14, 2005 - link
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 PackJep4444 - Wednesday, September 14, 2005 - link
i never heard of the X800LEGriswold - Thursday, September 15, 2005 - link
There is a X800LE, friend of mine got one. Cant say I've seen many being sold though.mistersnail - Wednesday, September 14, 2005 - link
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 ^^Jep4444 - Wednesday, September 14, 2005 - link
the X800SE came out close to launch, the X800 came out at the same time as the XLjkostans - Wednesday, September 14, 2005 - link
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)OvErHeAtInG - Wednesday, September 14, 2005 - link
LOLBottom 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....

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?
