Note that the L1 cache has 4 cycles latency, the L2 cache has about 10
cycles latency, and the L3 cache has about 50 cycles of latency.  If
you use the L3 cache as register file, it will be 8MB large, but you
will have 50 cycles of latency, and it has only one port per 2MB slice
(for four cores), so even if you can circumvent the latency issue, you
will typically only have one instruction every three cycles on every
core (compared to four on a real Sandy Bridge).
