Intel releases Xeon E7 v2 chipset

by Nick Farrell |
www.fudzilla.com
Beyond two times better performance power, Intel is promising a few other upgrades with the next generation of this data-focused chipset, including triple the memory capacity, four times the I/O bandwidth and the potential to reduce total cost of ownership by up to 80 percent.
There was also talk of 40W, 1.4GHz models at ISSCC but they have not been announced yet.
