Since AMD announced its core ZenD microarchitecture, we have anticipated the announcement of three product lines: Desktop Ryzen, Mobile Ryzen and Enterprise EPYC. So far, the desktop parts are now rolling out in retail (if you can find them), and the Ryzen mobile processors are part of AMD’s CES releases this week for retail in February. That leaves only Zen 3-based EPYC, which AMD selected as a preview today as part of its CES keynote presentation.
As for the design of the Zen 3 EPYC ‘Milan’ processors, we expect an almost apparent transition from the previous Zen 2 EPYC ‘Rome’ ecosystem with pin-compatible processors with up to 64 cores and 128 PCIe 4.0 lanes. When it comes to the performance of the desktop processors, we should also expect IPC growth of + 19%. The question of frequency and efficiency remains, and when AMD announces the batch of products we’ll see where the solution ranks compared to the competition – should AMD have a significant competitive advantage, prices will undoubtedly rise in line with good. The previous generation EPYC 7742 had a list price of $ 6,950 for comparison.
In today’s keynote, AMD CEO Dr. Lisa Su used the weather forecast simulation code known as WRF with two of Milan’s new 32-core processors against Intel’s popular 28-core Xeon Gold 6258R (We checked this). The demo showed the simulation of a 6-hour weather pattern over the continental US where Milan was 46% faster than Intel with two outlets. This was calculated based on the final frame cut-off from the simulation in the keynote, which showed that AMD was 56% complete at Intel and AMD was 82% complete.
AMD’s own metric then showed a difference of + 68% when comparing a single socket solution. AMD did not provide specific details about the rest of the system used in the tests. It should be clear that we cannot validate AMD’s performance claims as this is a preview.
We expect further details on the portfolio of Milan and AMD later this year. Better sooner than later.
