It's that last product family that is the focus of our attention today. Canard PC Hardware, a French website with a pretty good track record when it comes to leaks, claims to have obtained specifications for AMD's second generation EPYC processors (we’ll simply call it EPYC 2 for brevity). At first glance, things don't appear to be too out of the ordinary. The processors are rumored to still support up to 128 PCIe lanes and 8-channel DDR4 memory (although the memory spec has been bumped from 2666MHz to 3200MHz speeds).
Where things really get interesting is with the revelation that the maximum core count has increased from 32 cores to 64 cores. That means that the top-spec EPYC 2 part will be capable of executing a staggering 128 threads.
The final piece to the puzzle comes with respect to L3 cache, and this marks another significant upgrade. Current EPYC processors feature 2MB of L3 cache per core, with the current 32-core EPYC 7551P featuring 64MB of total L3 cache. The leak from Canard PC Hardware suggests that this figure will quadruple, with 64-core processors serving as home to 256MB of L3 cache.
If AMD can manage to move its 12nm LP process technology and eventually 7nm, it's not out of the realm of possibility that 64 cores and 256MB of L3 cache could be crammed into future EPYC processors. In a follow-up tweet, the publication says that base TDP for the new processor will be 225W and will max out at 240W.
Back in March, the website managed to leak some news about an upcoming HEDT processor family from AMD. At the time, we didn't know that it had revealed specifications for what was to be known as Ryzen Threadripper. Will the publication's sources ring true again when it comes to these EPYC 2 specs? We definitely hope so.

When it comes to server processors with tons of cores, Intel’s Xeon Phi line takes the crown, but just as AMD’s Zen could be a rival to Intel’s Core series chips in the consumer market, AMD has now been discovered to be working on a rather impressive server chip codenamed Naples. With 32 cores (64-threads) on a 14nm die, it’s definitely a competitor outside of the super-high-performance server market, but now AMD has been discovered to have something far more exciting up their sleeve, a 7nm server chip currently codenamed Starship set to arrive shortly after Naples’ 2017 release.
It seems that in an aggressive bid at the server CPU market, AMD has skipped straight from 14nm to 7nm for Starship. Whether the name was chosen after the famous 80s band is unknown, but what is known is that the chip will have 48 cores running 96 threads for high-performance servers. On top of that, Starship will also cover versions of the chip with fewer cores aimed at mainstream servers and desktop applications.
Of course, right now it is just a concept, so there is little we can infer about true specifications or release of Starship, but it has a projected release date of 2018, most likely towards the end of the year. A 2018 release also means that GlobalFoundries will be ready and able to manufacture 7nm around that time and with the follow-up to Zen expected to be with GlobalFoundries, it may also be a 7nm chip. This is a highly exciting prospect as if Starship remains on track, we could be less than 24 months away from 7nm desktop CPUs.
