AMD Officially Announces Ryzen 9000 “Granite Ridge” Processors

AMD today officially announced its brand new Ryzen 9000 series desktop processors. These chips are built in the socket AM5 package and are drop-in compatible with all current AM5 motherboards with a BIOS update. Ryzen 9000 series processors are based on the new “Zen 5” CPU microarchitecture with the CPU complex dies (CCDs) being 4nm and wired to a 6nm I/O die. AMD states that Zen 5 will have a 16% IPC increase over “Zen 4”.

This 16% IPC increase is thanks to branch prediction improvements, wide pipelines and vectors, and deeper window sizes across the core design for more parallelism. They have also doubled the instruction bandwidth for front-end instructions, FPU to L1, and L1 to L2 data bandwidth. There is also a redesigned FPU to double AI Performance and AVX512 throughput.

These “Granite Ridge” processors will feature a chiplet-based design much like what we saw in Ryzen 7000, 5000, and 3000 processor designs. This series will see CPU core counts that range from 6-core, 12-thread to 16-core, 32-thread. 6 and 8-core models will have a single CCD design, while 12-core and 16-core models will have a dual CCD design. Each CCD will have a single CCX (CPU Core Complex) with 8 “Zen 5” CPU cores. Every one of those cores will have 1MB of dedicated L2 cache and each of the cores will share 32MB of L3 cache. When it comes to the I/O die it looks to be unchanged from the previous generation, so it has a basic iGPU based on the RDNA2 architecture with 2 compute units, a dual-channel DDR5 memory controller, and a 28-lane PCI-Express Gen 5 root complex.

The Ryzen 9000 processor lineup is going to start with four models. First at the top we have the Ryzen 9 9950X which is a 16-core, 32-thread part with a maximum boost frequency of 5.70 GHz and a TDP of 170W. After that is the 12-core, 24-thread Ryzen 9 9900X and has a maximum boost frequency of 5.60 GHz and TDP of 120W. The Ryzen 7 7900X is an 8-core, 16-thread part with maximum boost frequency of 5.50 GHz and 65W TDP. And finally the Ryzen 5 9600X which is a 6-core, 12-thread part that has a maximum boost frequency of 5.40 GHz and TDP of 65W.

AMD only released performance numbers for the top-end Ryzen 9 9950X, which they directly compared to the Intel Core i9-14900K. Looking at the performance we can see AMD taking the lead over Intel with a 7% to 56% better performance productivity and content creation and a 4% to 23% better performance in gaming. For AI acceleration Mistral LLM is shown running 20% faster on the 9950X compared to the i9-14900K. No word yet on pricing, but we should know more as we get closer to the July 2024 launch.

At the same time AMD is also launching the AMD X870E and X870 chipsets. These will bring with them a new wave of AM5 motherboards. Some new changes will be USB 4.0 standard on all boards, PCI-Express 5.0 x16 on all boards (even X870), and the new boards will enable high AMD EXPO memory frequencies as well. These new processors will be compatible with current AMD 600-series chipset motherboards with a simple BIOS update and older Ryzen 7000 and 8000 chips will work on the new AMD 8000 series chipset motherboards.
