AMD Zen 5 Storms into Gaming Desktops with Ryzen 9000 "Granite Ridge" Processors
AMD today announced its much awaited Ryzen 9000 series desktop processors. Built in the Socket AM5 package, and drop-in compatible with all current AM5 motherboards with a BIOS update, the processors are based on the new "Zen 5" CPU microarchitecture. The operational part of the processor, the CPU complex dies (CCDs), are built on the 4 nm process, wired to a 6 nm I/O die. AMD didn't get down into the nuts and bolts of the microarchitecture, but briefly mentioned an impressive 16% IPC increase over "Zen 4." Coupled with the fact that the first wave of processors lack 3D V-cache and can sustain higher boost frequencies and TDP, processors in the series should beat the Ryzen 7 7800X3D in gaming performance, which also means that AMD has beaten the 14th Gen Core "Raptor Lake Refresh" processor series by a significant margin.
The 16% IPC increase over "Zen 4" is backed by branch prediction improvements, wider pipelines and vectors, and deeper window sizes across the core design, for more parallelism. The core also features doubling in instruction bandwidth for front-end instructions, FPU to L1, and L1 to L2 data bandwidth, and a redesigned FPU to double AI performance and AVX512 throughput. The company hasn't put out a block design for "Zen 5," and we'll learn more about it in the run-up to the market availability of these chips some time in July 2024.
