Notebook-bound Core 2 Extreme tested

— 2:19 PM on July 10, 2007

The folks at Belgium-based hardware site Matbe have put together a short review of an upcoming high-end Intel processor called the Core 2 Extreme X7800. This chip is unique because it's the first Core 2 Extreme model aimed at notebooks. It's based on the same Merom core as mobile Core 2 Duo T7000-series processors, and it runs at 2.6GHz—200MHz faster than the top-of-the-line Core 2 Duo T7700. This higher clock speed gives the X7800 a power envelope that's 9W higher than that of the T7700, although both chips have the same 800MHz front-side bus and 4MB of shared L2 cache.

Beyond the extra MHz, one of the most interesting aspects of the Core 2 Extreme X7800 is its unlocked multiplier. Matbe says the BIOS on their prototype X7800-powered notebook allows users to choose between speeds of 2.6GHz, 2.8GHz, and 3GHz. Battery life at 3GHz probably isn't great, but Matbe found that the machine lasted anywhere between 46 minutes and 142 minutes at 2.6GHz depending on the load level and power profile. 142 minutes translates to nearly two and a half hours, which doesn't seem too bad for a high-end notebook.
