been lucky enough to get its hands on the first Core 2 Extreme X7800 based notebook, an Asus G2S and they've put it through its paces. The CPU is clocked at a default speed of 2.6GHz at an 800MHz bus, but it overclocks to 3GHz.
The Asus G2S notebook features the Intel 965PM chipset, 2GB of DDR2 667MHz memory, a GeForce Go 8600M GT with 256MB of GDDR3 and a 200GB Toshiba 4,200rpm SATA hard drive.
Matbe has run a a fairly complete set of benchmarks on the system and although they've compared it to a Core 2 Duo T7300 at 2GHz, it doesn't seem like the X7800 is that much faster at default clock speeds compared to the T7300, especially in some of the game tests.
