AMD Unveils "Zen 2" CPU Architecture and 7 nm Vega Radeon Instinct MI60 at New Horizon

[bug]

Since 7nm has 50% power reduction, adding 50% more cores gets you back to the same power envelope or close to. The other thing you need to consider is ROME has PCIeX 4 and I'm no sure how that will work with the current boards. We know Amd was already working on ROME/ ZEN2 while designing the socket so they could have made it to support 64 cores.

It's also a mix of 7nm cores and 14nm IO core. I know I wouldn't want to be in the team sorting this out

I think that Rome will work at PCI E 3 in current Mobos, if you want PCI E 4 you need a new Mobo. Perhaps 32+ cores CPUs will require a new Mobo too. Could also be that even using same socket there is no compatibility (like 1151, Coffee Lake can't be used in 100 o 200 Mobos).

The number of instructions executed per clock is not a constant for a given processor; it depends on how the particular software being run interacts with the processor, and indeed the entire machine, particularly the memory hierarchy.

Can't wait to build my new rig... I'm still with my i7 860 ^^
I have a i7 3770 still in an empty rig, but I'm tired of reinstalling all of my software and configuration...

Well... you fixed it one place but not everywhere... 128 lanes of pcie 4 not 96

Sry... I clicked reply on the article and it replied on the last post for some reason.
The article has the incorrect amount of pcie lanes. Rome has 128 pcie 4 lanes not 96.

Makes more sense so
