AMD Announces Zen 5-based EPYC “Turin” Processors: Up to 192 Cores, Coming in H2’2024

With AMD’s Zen 5 CPU structure solely a month away from its first product releases, the brand new CPU structure was positioned entrance and heart for AMD’s prime Computex 2024 keynote. Outlining how Zen 5 will result in improved merchandise throughout AMD’s whole portfolio, the corporate laid out their product plans for the total triad: cellular, desktop, and servers. And whereas server chips would be the final components to be launched, AMD additionally saved the perfect for final by showcasing a 192 core EPYC “Turin” chip.

Turin is the catch-all codename for AMD’s Zen 5-based EPYC server processors – what is going to presumably be the EPYC 9005 collection. The corporate has beforehand disclosed the identify in earnings calls and different investor capabilities, outlining that the chip was already sampling to clients and that the silicon was “trying nice.”

The Computex reveal, in flip, is the primary time that the silicon has been proven off to the general public. And with it, we’ve acquired the primary official affirmation of the chip’s specs. With SKUs as much as 192 CPU cores, it’s going to be a monster of an x86 CPU.

Although solely a quick tease, AMD’s Turin showcase did affirm a number of, long-suspected particulars concerning the platform. AMD will as soon as once more be utilizing their socket SP5 platform for Turin processors, which implies the chips are drop-in appropriate with EPYC 9004 Genoa (and Bergamo). The reuse of SP5 implies that clients and server distributors can instantly swap out chips with out having to construct/deploy entire new methods. It additionally implies that Turin may have the identical base reminiscence and I/O choices because the EPYC 9004 collection: 12 channels of DDR5 reminiscence, and 128 PCIe 5.0 lanes.

By way of energy consumption, present SP5 processors prime out at 400 Watts, and we’d count on the identical for these new, socket-compatible chips.

As for the Turin chip itself, whereas AMD shouldn’t be going into additional element on its configuration, all indicators level to this being a Zen 5c configuration – that’s, constructed utilizing CCDs designed round AMD’s compact Zen 5 core configuration. This might make the Turin chip on show the successor to Bergamo (EPYC 9704), which was AMD’s first compact core server processor, utilizing Zen 4c cores. AMD’s compact CPU cores usually commerce off per-core efficiency in favor of permitting extra CPU cores total, with decrease clockspeed limits (by design) and fewer cache reminiscence all through the chip.

In response to AMD, the CCDs on this chip had been fabbed on a 3nm course of (undoubtedly TSMC’s), with AMD apparently trying to benefit from the densest course of obtainable with a purpose to maximize the variety of CPU cores the can place on a single chip. Even then, the CCDs featured listed below are fairly sizable, and whereas we’re ready for official die dimension numbers, it might come as no shock if Zen 5’s increased transistor depend greater than offset the area financial savings of transferring to 3nm. Nonetheless, AMD has been in a position to squeeze 12 CCDs on to the chip – 4 greater than Bergamo – which is what’s permitting them to supply 192 CPU cores as a substitute of 128 as within the final technology.

In the meantime, the IOD is confirmed to be produced on 6nm. Judging from that truth, the photographs, and what AMD’s doing with their Zen 5 desktop merchandise, there’s a superb likelihood that AMD is utilizing both the identical or a really comparable IOD as on Genoa/Bergamo. Which matches hand-in-hand with the socket/platform on the different finish of the chip staying the identical.

AMD’s temporary teaser didn’t focus on in any respect some other Turin configurations. So there may be nothing else official to share about Turin chips constructed utilizing full-sized Zen 5 CPU cores. With that mentioned, we all know that the full-fat cores going into the Ryzen 9000 desktop collection pack 8 cores to a CCD and are being fabbed on a 4nm course of – not 3nm – in order that strongly implies that EPYC Zen 5 CCDs would be the identical. Which, if that pans out, implies that Turin chips utilizing excessive efficiency cores will max out at 96 cores, the identical as Genoa.

{Hardware} configurations apart, AMD additionally showcased a few benchmarks, pitting the brand new EPYC chips towards Intel’s Xeons. As you’d count on in a keynote teaser, AMD was profitable handily. Although it’s attention-grabbing to notice that the chips benchmarked had been all 128 core Turins, reasonably than on the 192 core mannequin being proven off right now.

AMD shall be delivery EPYC Turin within the second half of this 12 months. Extra particulars on the chips and configurations will observe as soon as AMD will get nearer to the EPYC launch.
