The latest AMD ATI roadmaps reveal details of more DirectX 10 graphics cards

DailyTech has just finished its briefing on the upcoming AMD ATI Radeon launches.  The company has three major launches over the next few months: codenamed R600, R610 and R630.

The R600, ATI's ultra-high-end Radeon X1950 successor, has a production date scheduled for February 2007.  The card will launch at or around the Cebit 2007 convention in mid-March.  Shipments will follow shortly after.

Our latest roadmaps indicate R600 will support unified shaders and GDDR4 or GDDR3 memory.  GDDR3 versions of the card running revision "A12" silicon appear to be making rounds in the blogsphere, and select press can even take a sneak peak  of the card under embargo here at CES.  The final silicon for R600 will be "A13."

A GDDR4 version of the card will be the flagship launch product. Clock frequencies on any R600 card have not been set officially yet, and will not appear on marketing material until just a few weeks before the launch.

The company has also added the R610 and R630 GPUs to the roadmap.  In the past, ATI has used lower number codenames to denote entry-level products.  We would suspect R610 would be the entry-level R600 cutdown, and R630 would be the mid-range chipset.  The Radeon roadmap puts both of these products on the shelf before June 2007.

All R600-series GPUs from ATI are compatible with DirectX 10.

Late, maybe, but if the product is good, I don't think it really matters. Worst case scenario for ATI, Nvidia come up with a new product not too long after the R600 release or they lower their price, either ways, we ( the consumers ) win.

As for your Xbox360 comment: A friend of mine is working at EA , in shaders programming on the 360 to be more precise. At home he happens to have a X1900XT because it's at the core, while being less powerful than the 360 GPU, a very similar GPU that he can use to improve or develop new shadders for the game he's working on. So the for the Xbox360 ATI took a similar approach like Nvidia did on the PS3.

Let's see the products that came out to meet the expectations and were late from original date. Hmm... hmm... hmm... I can't think of any.

Prescott... NV30... R520...

Now for software it might be different.

Too bad Prescott was crap due to it's high heat and inability to reach the clock rate that it's extra long pipeline was designed for.

Did you happen to figure out that people like you are annoying?? Did you fail to understand what I was trying to point out??

Can you really not figure out what Prescott/NV30/R520 had in common??

Somehow you have a belief NV30 and R520 was an EXCELLENT product.

The R580 (X1900) is a hybrid of the R300-based and R600 architectures. It does not have programmable pipelines or any of the non-graphics enhancements that the R600 does, but it is not derived from the "Xenos" GPU. The Xenos is, if you want to think of it hierarchically, the "parent" of the R600 architecture. The R300 "architecture" was discarded when the switch was made to Unified Shaders.

Conversely, the "RSX" from the PoS3 is based on the G70, lacking Unified Shaders and the other non-graphics enhancements of the R600/G80 generation. To look at in simplistic terms, the PS3 has an 7950 GPU, and the X360 has an R600 GPU.

This is no fault of nVidia's, Sony had initially planned to have no graphics chip of any kind in the PS3, assuming that Cell's almighty abilities would suffice for such operations - however developers disagreed, and at the last moment Sony approached nVidia (ATI was otherwise engaged) and asked them to hack a graphics chip into the console.

Yes you are right but from what I've been told from this friend of mine that was the closest GPU you could find on the market when he bought the card last spring.

I don't think your "simplistic terms" are accurate.

The PS3's GPU is based on the 7800 GTX. The RSX only has 256 MB of GDDR3 VRAM @ 700 MHz. The 7950 GTX is much more powerful since it is essentially two 7900 GTX cards put together (though it takes two PCIe x16 slots). In theory, even a single 7900 GTX would be faster than the PS3's RSX.

Also to say that the X360 has an R600 GPU is quite a stretch. Its a full generation ahead of the X360 and it supports DX10 (besides the fact that it has faster clock speeds, more VRAM, etc.).

At least thats what I've read...

The PS3 is based on the 7800GTX but it is nothing like the 7950GX2 (the dual GPU card). Nor is the 7950GX2 two 7900GTX cards put together. It is more akin to two 7900GTs put together but with a slightly faster core and slower memory at stock speeds. And there is no 7950GTX, there is the 7950GT which is a version of the 7900GT with faster core and memory speeds and available with 256MB or 512MB of RAM.

And yes a 7900GTX would be faster than RSX since RSX is crippled to save cost. It only has a 128bit memory bus vs. a 7800/7900s 256bit bus and only 8 ROPS instead of 16. Both are huge bottlenecks.

Read harder.
