PORI, Finland--(BUSINESS WIRE)--Oct. 26, 2005-- An independent team of Finnish over-clockers has made world
history by over-clocking a graphics processor to engine clock levels
above 1 GHz. The record was set on the recently-announced Radeon
X1800 XT graphics processor from ATI Technologies Inc.
(TSX:ATY)(NASDAQ:ATYT).
Noted Finnish over-clockers Sampsa Kurri and Ville Suvanto
achieved graphics engine clocks of 1.003 GHz and a memory speed of
1.881 GHz (940.50 MHz DDR (dual data-rate) memory clocks) with
maximum system stability and no visual artifacts.
The team, optimistic that higher speeds could ultimately be
achieved with the Radeon X1800 XT, attained the record speeds using a
custom-built liquid nitrogen cooling system that cooled the graphics
processor to minus-80 degrees Celsius. "We're just warming up," joked
Kurri. "But we believe that the Radeon X1800 XT has even more
over-clocking headroom, and in the coming weeks we expect to achieve
higher clock speeds and even greater performance levels."
"It's impressive to see the Radeon X1800 XT architecture achieve
1 GHz core speed and approach 2 GHz memory speed, which far exceeds
the specifications of the memory devices," said Stan Ossias, Sr.
Product Manager, Desktop Products, ATI Technologies Inc. "Once faster
GDDR-4 memory arrives next year, users can expect to see the hidden
potential of ATI's innovative new memory controller design complement
our powerful shader engines with massive additional memory clock
scalability."

Radeon X1800 XT's extreme clock-scaling capabilities are made
possible by a series of key innovations that include use of the
state-of-the-art 90-nanometer semiconductor process technology, an
efficient new Ultra-threaded Shader Model 3.0 architecture, and a
revolutionary new 512-bit ring-bus memory controller.
