Intel plans to deliberately limit Sandy Bridge overclocking

[Hornet331]

Half a megabyte per each core's cache block is reserved for a GPU,so QC SB has 6(8)MB and SB-E has 15MB of usable cache(or following the previous math,actually 3x6=18MB of total cache).

SB-E has no gpu...

edit: ok that part with the gpu makes sense, so we have 2mb cache for the gpu alone, not bad.
