Medusa, in fact, is the identify of the youngest of the three gorgon sisters from Greek mythology. She was famously depicted as a girl with snakes for hair, who, if you happen to met her gaze, might flip you to stone. There are quite a lot of totally different metaphors you might draw on for naming a processor “Medusa”, together with a number of cores, and even a number of MCDs. Everest appears to assume that Medusa will use a single IOD and two CCDs similar to extant Zen processors, although.
We say that due to this tweet, the place he highlighted an edited picture that he beforehand shared together with the comment that “Medusa will use 2.5D interconnect with a a lot larger bandwidth.” In different phrases, not less than in accordance with Everest, Zen 6-based client processors might be in-built a way somewhat like high-end RDNA 3 GPUs.
As you may know if you happen to learn our RDNA 3 Architecture Overview, AMD went to nice lengths to develop a high-speed hyperlink for the GCD and its MCDs in Navi 31. Known as “Infinity Links”, they function at practically 10 instances the bandwidth of the hyperlink between a Ryzen or EPYC cIOD and its CCDs. AMD gave the determine of 5.3 TB/second peak bandwidth between GCD and MCDs.
Interconnect efficiency just isn’t often a limitation for desktop Ryzen processors, however for EPYC, in dense multi-threaded workloads, it definitely might be. We doubt something on the order of 5.3 TB/second will present up on a desktop Ryzen processor, however we would not be shocked if the Zen 6 cores in “Medusa” are certainly capable of talk way more rapidly with the I/O die and thus the remainder of the system.
There’s not prone to be any verified leaks of Zen 6 till late this 12 months or early subsequent 12 months, because the components aren’t anticipated to seem till late 2025 on the earliest. Still, it is attention-grabbing to invest about what might come sooner or later. For now, we’re pumped to see AMD’s next-generation components, as Zen 5 is supposedly a full rework of the Zen core design over Zen 4. We’ll see quickly sufficient.
