Part i3, i5 upgrade K0 stepping

Intel today announced a step upgrade of the three boxed processors Core I3-530, Core I3-540, and Core I5-650, all from C2 to K0.

The changes in this step-by-step conversion are:

1. The extended CPUID number changes from 0x00020652 to 0x0020655.

2. Host RevID number changed from 0x12 to 0x18.

3, increase support for processor context ID (PCID). (Processor Context ID: One of the core improvements to the 32nm architecture, mainly for improving performance in multithreading or in a large number of small-scale virtual machine environments.)

4, old and new stepping pins compatible.

5, the new S-Spec, MM number, see figure.

K0's new step-by-step boxed versions of Core I3-530/540 and Core I5-560 will begin shipping on October 16th.

Prior to this, Intel has carried out a similar step upgrade for the bulk versions Core I5-670/661/660/650, Core I3-540/530, and Pentium G6950, which are also part of the 32nm Clarkdale processor family. Exactly the same.
