According to a product change notification sent to Intel customers yesterday, Intel will be moving all of its 45nm Xeon DP processors from the C-O to the E-0 stepping. A total of 18 processors will get a new CPUID (0xA005b013): the Quad-Core Intel Xeon X5482, X5460, X5450, X5472, E5450, E5472, E5440, E5462, E5430, E5420, E5410, E5405, L5420, L5410 and dual-core Xeon X5272, X5260, E5205, and Intel Core 2 Duo L5240 processors. The new stepping chips will have the same specs, only the Xeon DP X5482 CPU will have its TDP changed from 150W (C-0) to 130W (E-0). However, a BIOS update will be required in order to run the new stepping CPUs. First E-0 samples are expected to become available on July 3rd. The updated processors are scheduled to begin shipping on October 6th.
