More chipsets, more GPUs, more options

DailyTech today reported on ATI's announcement of just how it will offer physics processing in its lineup. Using the latest Xpress 3200 (RD600) chipset, ATI is enabling physics processing by using a 3rd add-in card. Using an X1000 family card, a user can enable dedicated physics processing card after they have installed a CrossFire setup.

Physics however, remains only one of ATI's major announcements at Computex. DailyTech's legal counsel has advised us to stop posting corporate roadmap slides with trademarked logos (some sort of copyright thing), but we can still disseminate information the old fashioned way.  ATI has several new GPUs lined up for the second half of 2006:

  • RV505CE lowest end, 64-bit, 350MHz core / 250MHz memory
  • RV505LE low end, 128-bit 450MHz core
  • RV505 Pro
  • RV515 Pro

We will have more details on the above GPUs as they come.  The majority of ATI's new GPUs are expected to launch this August and September.

The last trick up ATI's sleeve for 2006 is integrated Crossfire.  ATI RV560 and RV570 will use an on-chip Crossfire logic that will allow for any motherboard to use dual GPUs in Crossfire mode.  The composite engine used in the core still does not move all of the data across the PCIe lanes, and manufacturers insist to us that some sort of dongle or bridge will be needed between each card.

ATI's upcoming RV560 is a 128-bit pipeline, 450MHz core, 650MHz memory, 16x32 6 layer PCB. Roadmaps indicate that ATI will introduce both AGP and PCIe versions in August of this year. ATI's RV570 is identical (as far as we know) to RV560 except that it will have a 256-bit pipeline instead of 128-bit. Core frequency will remain the same as well as memory frequency.

At the most high end of ATI's mid-range is the RV570XT ASIC.  RV570XT will feature everything the same as RV570XL, but have significantly higher clock speeds.  The core clock speed should reach more than 600MHz and the memory clock speeds should obtain speeds near 1.1GHz.

By the end of the year, ATI will have at least samples for what the corporate roadmap calls "R580+."  Essentially R580+ is the R580 (Radeon X1900) ASIC with GDDR4 memory.  There is no word yet on clock speeds or release dates.

OEM partners did not have any details on R600.  The ATI roadmap so far carries the company through November. We reported earlier today that ATI's RS600 chipset gets a positive showing at Computex with several board releases from ATI partners.

Is this where we are heading?

Is this it? Being softly "forced" to use dual GPU? Hope they will use dual cores...

There's little point in dual core for graphics.

Dual core allows x86 processors to run multiple threads simultaneously. Graphics processors are already extremely parallel, and have plenty of room for further parallelization at the instruction level. Basically, rather than ever do dual core, they'll just keep making their processors able to handle more pixels in parallel. Or from another perspective, they are already at 16 'cores' and counting.

They don't want to make a single, double wide chip because yeilds would be problematic. So instead, they'll put 2 or more GPUS on a single board.

So I guess going the GeForce 7950GX2 route then? Oh, i can feel my wallet burning...

Indeed, though I'd expect with refinement that they'll get two GPUs onto one PCB intead of 2 pcbs.
