According to first partial specifications, Intel's enterprise Xeon E7 v3 Haswell-EX CPUs will have plenty of improvements, including increased number of cores, larger L3 cache, new instructions, support for DDR4 memory and will surely be interesting to see how much performance improvement are we looking at here.

According to a new report from CPU-World.com, we now have a chance to see some details and changes in E7 v3 lineup as well as some specifications which were recently leaked in the X series price list and System x3850 X6 and x3950 X6 Installation and Service Guide from IBM.

In case you missed it earlier, the Haswell-EX CPUs will be based on 22nm manufacturing process, have up to 18 cores, support for HyperThreading, up to 45MB of L3 cache, support for DDR4 memory, new AVX and TSX instructions and much more. The number of SKUs will apparently also be reduced from 19 down to 12, including four E7-4800 v3 SKUs and eight E7-8800 v3 SKUs.

The new Xeon E7 v3 lineup starts with E7-4800 v3 series featuring the E7-4809 v3, E7-4820 v3, E7-4830 v3 and E7-4850 v3 SKUs, which will pack 8, 10, 12 and 14-cores, respectively. Each of these CPUs will have 2.5MB of L3 cache per core, shared between all cores, for up to 20MB on the 8-core to up to 35MB on the 14-core SKU.

The Xeon E7-8800 lineup will be mostly based on 16- and 18 core models, with two exceptions. Intel also plans to include the Xeon E7-8893 v3 which will have 4 CPU cores, 45MB of L3 cache, 3.2 GHz clock rate and 140 Watt TDP as well as the E7-8891 v3 that will have 10 cores, lower 2.8GHz clock, same 45MB of L3 cache but 165W TDP.

The top part in this lineup is the Xeon E7-8890 v3 with 18-cores, 2.5GHz clock, 45MB of L3 cache and 165W TDP.

Of course, bear in mind that these are just first partial specifications and some might change as Intel officially launches these new Haswell-EX Xeon E7 v3 CPUs.
