Matbe.com has 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.

You can read the full test here, although it's in French, but the benchmarks are quite universal.
