Intel's Sandy Bridge-EP arrives late this year to take on AMD's Bulldozer in
2 and 4-socket servers. It offers up to 8 cores with a new system
architecture including 20MB L3 cache, 4 DDR3 memory controllers and faster
8GT/s QPI 1.1 links. Sandy Bridge-EP is also the first server CPU to
integrate PCI-E 3.0 on-die, with up to 40 lanes - a significant bandwidth
and power efficiency advantage.
This article compares the system architecture and design to previous
approaches and shows that Sandy Bridge-EP will be a compelling upgrade for
2-socket servers and attractive for certain 4-socket systems, particularly
those with large I/O needs.
