For the reason that announcement of AMD’s Zen 3 core microarchitecture, we’ve been anticipating three sequence of merchandise to be introduced: desktop Ryzen, cell Ryzen, and enterprise EPYC. Up to now the desktop elements at the moment are launched and at retail (if yow will discover them), and the cell Ryzen processors are a part of AMD’s CES disclosures this week for retail in February. That solely leaves Zen 3-based EPYC, which AMD has determined to preview as a part of its CES keynote presentation at this time.
So far as the design of Zen 3 EPYC ‘Milan’ processors go, we expect an virtually seemless transition from the earlier Zen 2 EPYC ‘Rome’ ecosystem, with pin-compatible processors providing as much as 64 cores and with 128 PCIe 4.0 lanes. For efficiency, if the desktop processors are something to go by, we must always count on to see +19% IPC beneficial properties as nicely. The query stays as to frequencies and effectivity, and when the time comes for AMD to announce the product stack, we’ll see the place the answer lies relative to the competitors – ought to AMD have a major aggressive benefit, little question costs will rise in line as nicely. The earlier technology EPYC 7742 had a ‘checklist worth’ of $6950 for comparability.
In at this time’s keynote presentation, AMD CEO Dr. Lisa Su showcased climate prediction simulation code generally known as WRF, with two of the brand new 32-core Milan processors up towards Intel’s standard 28-core Xeon Gold 6258R (we’ve reviewed these). The demo showcased simulating a 6 hour climate sample over the continental US, to which twin socket Milan was 46% quicker than Intel. This was computed based mostly on the ultimate body cut-away from the simulation within the keynote, which confirmed that the place Intel was 56% full, AMD was 82% full.
+68% for single socket, +46% for twin socket
AMD’s personal metric then confirmed a +68% distinction when evaluating a single socket answer. AMD didn’t present actual particulars on the remainder of the system used of their testing. It must be clear that as a result of this can be a preview, we can not validate AMD’s efficiency claims.
We expect extra particulars about Milan and AMD’s portfolio later this yr. Sooner relatively than later.
