There is an Intel slide surfacing in forums, and that slide definitely seems to be legit. It indicates a new Xeon processor to be launching on March 31st. The interesting part here is that it is a based on Broadwell-EP architecture. The chip would be launching as Xeon E5-2600 V4 series.

As the Intel slide indicates the "Broadwell-EP" CPU is to offer at least "20% more cores and last-level cache" compared towards "Haswell-EP." Perhaps 10 cores over 8 at the same price ? Or even 8 cores at the price of a 6 core version ? Who will know. 

The slide on average 18% more performance opposed to Haswell-EP." Also interesting to see is native support for DDR4-2400 MHz, which to date always has been DDR4-2133 MHz.

Intel Xeon Broadwell-EP Could Launch at the end of the Month ?
