Meet AMD Zen 5

AMD Ryzen 9000 And Ryzen AI 300

TechPowerUp have posted details on the design of Granite Ridge, Strix Point and Turin, all running on the new AMD Zen 5 architecture.  As with previous generations of Zen AMD has chosen to refine their architecture instead of making sweeping changes as Intel has been doing.  This makes the launch a little less exciting, but means AMD should avoid the problems Intel has been facing with Raptor Lake and it’s rather aggressive motherboards.  AMD has moved to 4nm for this generation and have focused on power efficiency as opposed to huge leaps in core counts or performance.  That’s not to say Zen 5 won’t be better at some tasks, choices such as moving from a 6-wide dispatch retire queue to 8-wide and giving AVX-512 a full 512-bit data path will improve productivity up to 16% according to AMD.

The on-chip graphics will now be RDNA 3.5, reportedly offering significant improvements on power efficiency which is partnered with a 50 TOPS NPU powered by XDNA 2.  This means both desktop and laptop processors will meet or exceed the requirements for Microsoft Copilot.  The socket remains unchanged, and current AMD motherboards will support AMD Zen 5 after a BIOS update.  We will see an 800 series chipset, however little will have changed from the precious generation apart from USB4 and the possibility of adding PCIe 5.0 slots on lower end models.

We will see notebooks with AMD Ryzen AI 300 chips announced this week, Ryzen 9000 desktop chips by July 31, 2024 and Turin based server chips not long after.  One thing we will have to wait for is a Ryzen 9000X3D chip; V-Cache is still going to be a thing with AMD Zen 5 but we don’t know when we might see a release.

TechPowerUp dives much further into the architecture in their article, check it out for the full details.
