#2Salient point:

Epyc (formerly Naples) is the server-grade arch with 8 memory channels, 32 cores and 128 PCIe lanes per socket.

#364 lanes would be good for something like 4-6 GPUs @ 8 lanes per, and some high speed storage/networking?
Anxiously awaiting Intel's "I am not left handed either" response.

#4We all benefit when AMD is a player.
And this player is fighting HARD right now. Me gusta.

#5The huge number of PCIe lanes is pretty exciting to me. For consumers, the limiting factor in PCs these days tends to be I/O. With this, you could have 4 PCIe M2 SSDs (that's a bit under 16Gbps bandwidth, assuming RAID0), and still have 44 lanes (the number in the top-end Intel CPU) to spare for GPUs and other peripherals.

#6I was of the opinion that Intel will only face real competition when arm reaches parity with desktop class cpu. Nice to see AMD rise back up again. Hope Intel is not able to strong arm the oems like last time when AMD had design wins but Intel using anti competitive practice stalled its growth till it was able to catch-up and later go ahead.

I don't fully understand. So 1 SSD need 1 lane. How many lanes need something like NVisia 1080Ti? What use of the remaining lanes? If I want to build something like 1 CPU/1 GPU/1 SSD configuration without additional peripherals, 62 lanes will be effectively wasted?

The newer M.2 SSDs suck up 4 lanes. That's 16 lanes for four drives, burning through all available lanes on a Kaby Lake CPU.

Consumers tend to be limited by not having many PCIe SSDs in RAID0?
Who are these people and what do they need galactic disk bandwidth for?
