Likely to attract the most interest, however, is the top-end X7350 processor, which clocks in at 2.93GHz with 8MB of shared on-chip cache and a thermal design power rating (otherwise known as TDP) of 130 watts.

If that's all a bit too much for you, Intel's also rolled out two dual-core Tigertons, including 2.93GHz E7220 and the 2.4GHz E7210, each of which have a TDP of 80 watts and 8MB of shared on-chip cache.

The Duron also includes a larger on-chip memory cache than the K6-2, and AMD's Enhanced 3DNow instructions, designed to boost multimedia performance.

When the K7's on-chip 128KB L1 cache becomes too small, the K7 will call on the 200-MHz EV6 bus developed for Digital's Alpha processors.
