This probably means Skylake is just Haswell with larger buffers and a wider FPU. It may well have only the same capabilities as Haswell (In regards to concurrent execution / ILP extraction).

Has anyone seen this?

Up to 32 physical cores and 8 channel DDR4? Granted, on the server side, but still.

Octo-channel DDR4? Goddamn. Wiring that up is going to be interesting.

And since its likely going to be dual-16c CPUs in a single package, what are the odds AMD will have a high end 16C SKU for the consumer side?

I think Octo channel is ok for high end servers due to the design. Ultra high end servers have RAM slots on a separate circuit board rather than on the mainboard so space isn't an issue. On the other hand, single module 16c quad channel is entirely possible for high end consider. We already have quad channel with Intel so its entirely possible with AMD, only issue is power consumption. MAybe it will be 200W TDP?

A 16c at 200W TDP? I'd be game. It'd mean that a standard 8c would theoretically fit within a 100w TDP. As my own current Xeon is rated for 135W and is on a much older node (32nm planar), I easily see a 100W 8c/16t CPU on 14nm finfet being possible.

Sign me up for any of those thumb.gif

Expect 200W+ for a server 4TF APU.

Assuming it is point-to-point, it would be an insane amount of connections. They may use an intermediate interface, though, so they may only have another ~30 pins or so, though the performance will not be the same if that would be the case.

This is one rumor I don't think has much merit... Unless AMD wants to have two server sockets.

I wouldn't be surprised if we see 16c 4-channel memory on the AM4 socket and then 32c 8-channel memory on a G34 replacement.

AM4 is dual channel DDR4. Eight channels mean four die MCM package.
