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
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.
