After the Computex Keynote today on stage, where AMD revealed its new Ryzen family of processors coming on 7/7, we had a chance to speak with AMD’s SVP and GM of the Datacenter and Embedded Solutions Group, Forrest Norrod. Specifically, we asked him about the ‘Road to Rome’, which AMD stated will be coming in Q3 this year. We have a full transcription of the interview planned, but a couple of key points came out of our discussion.
First, Forrest revealed/confirmed the name of the Zen 4 based EPYC processor that will go beyond Rome and Milan. That name is Genoa, which is follows the Italian naming pattern. Forrest also said that the Zen 5 product follows that pattern, but failed to elaborate what that name is. I was told that the goal with each generation is to make sure the low hanging fruit for performance on each design is taken, and that there is a continual drive for compute performance. Forrest wouldn’t comment on the timeframe for Genoa, but did state that Milan is a mid-2020 platform, and so Genoa is likely 2021/2022.
|AMD EPYC CPU Codenames|
|1st||2017||Naples||32 x Zen 1|
|2nd||2019||Rome||64 x Zen 2|
|3rd||2020||Milan||? x Zen 3|
|4th||?||Genoa||? x Zen 4|
|5th||?||?||? x Zen 5|
The other snippet of information I wanted to break out from the interview is about the new Frontier supercomputer that was recently announced. This machine, built with AMD CPUs and GPUs, has a goal of being the most powerful supercomputer in 2021, measuring around 1.5 ExaFLOPS, making it a truly exascale machine. It has been largely assumed that this would be a combination of Milan CPUs and Radeon Instinct GPUs, and it would be connected CPU-to-GPU and GPU-to-GPU by Infinity Fabric rather than PCIe or CCIX. Forrest explained that the CPU is not Milan – it is actually a fully custom design CPU specifically for this project.
Forrest clarified that this custom CPU is not in the same way that Intel defines custom – i.e. it’s not simply the same silicon with adjustments in core counts / frequency / cache. The CPU for Frontier will be a fully custom design, built with CPU-to-GPU IF links in mind, without any excess. When asked if IF is going to be a connectivity in other platforms, Forrest would only confirm that it’s the connectivity for Frontier. Though, for what it's worth, AMD announced back at the Frontier unveil that the CPU would ultimately become available for other enterprise customers as well.
As mentioned, I’ll be trying to transcribe this interview ASAP, along with our Lisa Su roundtable. Stay tuned for more of our Computex coverage.

Eastman - Monday, May 27, 2019 - linkYou guys are always late to the party. AdoredTV kinda mentioned all of that already.
Ian Cutress - Monday, May 27, 2019 - linkWe knew it already too, and other stuff besides. But getting it confirmed direct from AMD is worth doing and reporting. Rumors are still rumors until confirmed.
JanW1 - Monday, May 27, 2019 - linkMust. Be. Fast!
Who cares about verified and reliable content?
shabby - Monday, May 27, 2019 - linkAdoredTV also confirmed 16core 5ghz zen2 chips...
haukionkannel - Monday, May 27, 2019 - linkHeh! At year 2030 ;)
Hifihedgehog - Wednesday, May 29, 2019 - linkActually, March 2020. Bits 'n Chips, who has been reliable as a leaker, just got word that 5 GHz parts are on schedule for a release on Athlon's anniversary.
Hifihedgehog - Wednesday, May 29, 2019 - linkSo AdoredTV was right. The quoted dates were just a bit off as we have found is all.
Eris_Floralia - Monday, May 27, 2019 - linkMost of the press already know that.
The stuff press can tell ppl is usually just the tip of the iceburg.
Haawser - Monday, May 27, 2019 - linkThings are getting crazy (or maybe that should be Crayz ?). I remember an article written a few years ago that predicted it would take until ~2030 before we had computers that could match the human brains ~1 exaflop of compute. And yet here we are looking at ~1.5 exaflop by maybe 2022....Amazing.
boeush - Tuesday, May 28, 2019 - linkYou're misremembering, most likely; I bet that article was talking about zettaflops, not exaflops - which is another factor of 1000x beyond Frontier, and 2030 still sounds about right for that...
