If i was to buy a new CPU, for me would be 8/16 version of Thread Ripper. A perfect CPU from Price/Performance point of view. What i like about it is 64 PCIe. AMD really did great here when Intel said that extra PCIe is not worth it, AMD went Opposite. 64 PCIe --> so many possibilities.
Really? Because those 64 are shared beyond just the x16 PCIe slots. In fact the board Toms has is only setup to do x16/x8/x16/x8 unless you plan to use the U.2 slot which shares PCIe with the PCIe_x8/X4_4. If you use that slot U.2 is disabled. If you use U.2 then that slot is disabled.
In all you get 48 total PCIe lanes from the CPU just to GPU if you plan to, for some reason, do Quad SLI/CFX. Most boards will probably be built in this same manner since this is geared towards tackling Intels HEDT market and not the mainstream market.
I am not sure where the other 16 from the CPU go, possibly storage and the NIC but wont know until more specs are released. However you can go to Asus website and read the manual for that board right now. I wouldn't be surprised if those other 16 are being used for other means.
This actually brings it closer to being similar to X299, especially if you consider that the CPU and Chipset have their own PCIe 3.0 lanes.
I am more interested in power, temps and clock speeds. It is after all a 180W TDP CPU.
