TC Mag reports Intel will roll out new QX9650 processors with C1 stepping in March.
Planned to be available from March 3rd on, the C1 stepping CPUs will feature new SSPEC and MM numbers and a new CPUID - 0x00010677.
The rest of the specifications of the C1 stepping remain unchanged from C0 but motherboard makers will still have to release new BIOS versions in order to support it. No biggie.
