Datasheet Volume One
Overview
46-bit physical addressing and 48-bit virtual addressing
1 GB large page support for server applications
A 32-KB instruction and 32-KB data first-level cache (L1) for each core
A 256-KB shared instruction/data mid-level (L2) cache for each core
Up to 20 MB last level cache (LLC): up to 2.5 MB per core instruction/data last level
cache (LLC), shared among all cores
The Intel® Xeon® processor E5-4600 product family supports Directory Mode,
Route Through, and Node IDs to reduce unnecessary Intel QuickPath Interconnect
traffic by tracking cache lines present in remote sockets.
