14nm Broadwell-EP with up to 22 cores
As expected and rumored earlier, Intel has now officially launched its new 14nm Broadwell-EP family of CPUs that will be sold as Xeon E5-2600 v4 series and feature up to 22 cores (44 threads) as well as bring several performance improvements and optimizations compared to the earlier available Haswell-EP Xeon E5-2600 v3 lineup.
Build on 14nm manufacturing process, the Broadwell-EP Xeon E5-2600 v4 will bring plenty of improvements compared to earlier available 22nm Haswell-EP Xeon E5-2600 v3 series, including up to 22 cores and 44 threads, up to 55MB of Last-Level Cache (LLC) support for up to 1536GB of eight-channel DDR4-2400 memory in 24 DIMM slots and featuring 40 PCIe lanes.
With 14nm manufacturing process, Intel should manage to lower the cost of manufacturing if it manage to maintain the yields similar to Haswell. While 22nm Haswell-EP had a 661mm2 die with 5.56 billion transistors, the 14nm Broadwell-EP pulls that down to 478mm2 but slightly higher 5.62 billion transistors.
The Broadwell architecture also brings plenty of other improvements include floating point instruction performance improvements, Translation Buffer (TLB) improvements, TSX- HLE/RTM + performance improvements as well as as various AVX instruction optimizations. All of these should give Broadwell-EP lineup a gain of up to 1.23x compared to earlier available Haswell-EP lineup, while maintaining the same 145W TDP.
The top part in the Broadwell-EP lineup is the Xeon E5-2699 v4, a 22 core chip with 44 threads, 55MB of LLC, base clock of 2.2GHz and the same 145W TDP. It ahs a price of US $4115, which is not a big surprise considering that this is a workstation Xeon part.
Intel's new Broadwell-EP can be considered as a minor update compared to the Haswell-EP chips, which could put off some server/workstation IT managers but also brings significant update compared to the Sandy Bridge-EP servers and workstation, which is probably the main target. Of course, higher number of cores, better performance and various optimizations could push some to upgrade the Haswell-EP server/workstations as well.
