More details about the upcoming 22nm Intel Xeon E5-2600 series
processors (aka Ivy Bridge-EP) are starting to leak out.
Initially, we will see the single-socket Xeon E5-1600 v2 series
and the two-socket Xeon E5-2600 v2 series processors, that share
the 22nm Ivy Bridge microarchitecture. They use the same LGA2011
socket as the current 32nm E5-1600 and E5-2600 series (Sandy
Bridge-EP), so that should mean that they will show up quickly
in existing server models, such as the Dell PowerEdge R720 and
the HP ProLiant DL380p Gen 8.  The chart that TechPowerUp found
does not show the physical core count for each processor model,
but we can infer that based on the total L3 cache size, since
Intel has been using 2.5MB of shared L3 cache for each physical
core in the Sandy Bridge and Ivy Bridge microarchitectures. That
means you can divide the L3 cache size (in MB) by 2.5 to get the
physical core count. Based on this calculation, it looks like
the Intel Xeon E5-2600 v2 processors will have from eight to
twelve physical
