Intel has now officially announced their Skylake based Xeon E3-1200 V5 “Greenlow” family of CPUs, with 11 new Skylake Xeon CPUs which will enter the market in 2016.
These new Xeon E3-1200 V5 will feature 20 Gen 3 PCIe lanes, which is a big upgrade over Skylake’s mainstream CPUs, also these new CPUs features Intel’s faster Iris and Iris Pro Graphics and Intel’s eDRAM. But some of these Xeon chips will not have an iGPU, which will be helps to lower power consumption.
This time Intel done a big change, now Xeon CPUs not compatible with mainstream Intel’s 100-series of Skylake ready motherboards. These Xeon E3-1200 V5 can only be used on Intel’s new Greenlow platform, which uses Intel’s C230 Series chipsets which offers DDR4 support and offers 20 lanes of PCIe Gen 3 bandwidth.
Intel this generation must have decided that an enterprise CPU must be paired with an enterprise motherboard, which makes a lot of sense from a compatibility standpoint, especially when it comes to validating mainstream motherboards.
I think Intel just want to stop users, who put $300+ Xeon CPUs to $80 mainstream motherboards.
