Intel Nehalem clock speed revealed

At IDF several press-members have been able to see Nehalem (next-generation Intel 45nm processors), actually working at a steady 3.2GHz. On an IDF demo machine the Processors tree lists eight "Genuine Intel CPU" entries with an "@ 3.20GHz" next to each of them. This isn't an eight-core CPU, though-the four extra cores are simply the work of Nehalem's simultaneous multi-threading implementation, which should work similarly to the Hyper-Threading feature of old Pentium 4s and Pentium Extreme Editions.

According to a recent press briefing by Intel's Pat Gelsinger, Nehalem chips will feature 256KB of L2 cache per core, 8MB of L3 cache per chip, and an integrated memory controller with support for up to three DDR3-1333 channels. Nehalem CPUs will also feature a number of architectural enhancements that should make them speedier, clock-for-clock, than current Core 2 offerings. The first Nehalem CPUs are scheduled to ship in the fourth quarter, but the rumor mill suggests the chips won't hit mainstream desktops until 2009.
