Using TSMC 5nm

AMD's latest financial analyst presentation spilt the beans on the outfit’s Ryzen 7000 Zen 4 CPUs.

The Zen 4 CPUs will be built on TSMCs 5nm process, will feature an IPC and frequency improvements, and will deliver up to a 125% improvement in memory bandwidth per core. They will require a new socket, and motherboards with new chipsets(opens in new tab) that feature PCIe 5.0 and DDR5 memory support. They will also include AI instructions and AVX-512 support.

AMD expects an 8-10 per cent instructions per clock (IPC) increase over Zen 3 and it looks like there were will be a greater than 15 per cent single thread performance gain. Some of these performance increases along with the advantages of moving to DDR5 memory make the Zen 4 look rather good.

The company expects its 16C/32T model, likely to be named the Ryzen 9 7950X to deliver a greater than 25% performance-per-watt improvement over the Ryzen 9 5950X(opens in new tab). Zen 4’s multithreading performance looks set to take a big jump, with AMD claiming a 35% performance uplift, much higher than the 15 per cent it expects from a single thread.
