    ATI's Radeon X1800 XT Breaks 1 GHz Speed Barrier
    Finnish over-clockers make world GPU history

    PORI, FINLAND/ Munich, Germany - October 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.

    Should we consider the above a hint to expect GDDR4 on R580?

    Just one little comment:
    Why would anybody refer to 1GHz as a barrier?

    For Core?? Why not?? has any other Graphics card hit the 1Ghz barrier?

    But it's totally goofy and arbitrary. I mean, breaking the 1.07231Ghz barrier makes as much sense as that.

    Um, 1 Ghz is a nice round number with another zero. Of course it's a "magic" barrier. Just like 1 Terrabyte will be a "barrier" with hard disk storage, etc.

    More of a milestone than a barrier. :)

    I'd say that the 1GHz barrier is important because it uses base 10, of course - blame evolution for giving us 10 digits on our hands.

    Of course, this doesn't explain why the human race doesn't use base 20 which would seem more logical...

    Well, some civilizations have used base 60 (Greeks, Babylonians).

    Sometimes I wonder why nobody ever used base 2. A finger straight could mean 1 and a bended one could mean 0. We could count till 1024 using all 10 fingers! :grin:

    Um.. I thought we were still at a 256-bit memory interface (32-bit x 8) with ATI (X1800)... was I missing something?

    The 512-bit bus is internal. The interface is still 256-bit.

    Last I recall, history remembers that Chuck Yeager broke the sound barrier. Sounds much more impressive than passing a milestone.

    Well, that actually was a barrier. There were many technical difficulties involved in going faster than the speed of sound (and he was just the pilot....it was more the engineers who are to thank for breaking the sound barrier). To put it simply, the aerodynamics required to go faster than the speed of sound are dramatically different than those required to fly below the speed of sound.

    This is why, for example, aircraft like the concorde and fighter jets have such dramatically different wing structure than airliners. And also consider the F-14, which changes the shape of its wings depending upon how fast it's flying.

    Now, 1GHz, there's nothing special about that. And I thought we all cared about performance over clock speed anyway.

    Not the extreme overclockers who did this! Clock speed is what counts for them.

    I think the bolded part counts as performance.

    Er, stability != performance.

    I mean, sure, that chip will be extremely fast. But so would a 700MHz G70 (with similar memory clocks).
