Intel Launches Xeon E7 v4 Processors

by Scott Michaud |
www.pcper.com
The E7-8XXX line can be run in an eight-socket motherboard, while the E7-4XXX models are limited to four sockets per system.
With Intel's Xeon naming scheme, the leading number immediately after the E7 in the product name denotes the number of CPUs that can be installed in a multi-socket system.
In an 8 Socket environment, eight of these chips would amount to 120 cores and 240 threads with a 300 MB cache shared via QPI v1.
Last year at IDF13, Intel launched their Xeon E5 ‘Ivy Bridge-EP’ parts enabling 2-socket platform designs in the server market.
