Dunno guys. With what i hear it means to me this thing is less power efficient than Skylake.
So, it's an okay HEDT chip, but something tells me AMD are not going to recapture any visible portion of server market.
Based on what exactly?
More cores per socket, more memory per socket, ball park power consumption, ball park ipc, ball park clocks.
Just to given an example current client I work at is running 2x8 core Xeon's with 384gb memory for VM farm SKU and we are still running out of memory.
Zen will be able to pack in more memory without going to larger dim's which can be a significant cost reduction in hardware ( especially the 32-64gb dimm transition).
Also remember that ZEN has a full NB/SB integrated with multiple 10gb NIC's so Zen has some extra base load as well in that TDP.
Most people fail to understand what matters in the server market. AMD's hardest market to compete in will be against high clock 4 cores in the consumer market. HEDT AMD looks not to bad and unless intel want to massively reduce prices AMD can find sweet spot, remember Zen looks to be smaller then Polaris (anywhere from 160mmsq to 220 mm sq is a possibility right now) and in laptop space Zen APU should do much better then CON core and with the superior GPU hopefully will be able to get good gains in market share.
Hopefully between now and release AMD can get the base clock upto 3.5ghz. that would be a 10% clock improvement from what AMD Polaris listed hopefully can push boost 1 core boost 10% higher as well as that would be 4ghz...... time will tell. Hopefully the 10gb NIC wont be disabled in the consumer "HEDT" variant as that could be a pretty nice bonus.
