AMD provides new Zen 4 details and touts a greater than 25% performance-per-watt gain
AMD's latest financial analyst presentation took place today, and in it we got some juicy information about the company’s upcoming Ryzen 7000 Zen 4 CPUs and RDNA 3 GPUs. I’ll go over the GPU announcements in another post, and focus on Zen 4 CPUs and AMD’s roadmap in this one. AMD disclosed its performance expectations for Zen 4 and bullishly laid out its plans for the next several years.
AMD, for obvious reasons, isn't revealing all of its secrets yet. That will have to wait for the actual launch, but we now know that 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 fleshed out the somewhat vague, though exciting performance claims it made at Computex(opens in new tab). We now know that AMD expects an 8-10% instructions per clock (IPC) increase over Zen 3. The same slide says we can expect greater than 15% single thread performance gain. The latter claim is interesting as it includes expected significant clock speed increases along with advantages of moving to DDR5 memory. It's possible that AMD is keeping its cards close to its chest as a 15% increase doesn’t sound all that impressive when everything is considered. It’s important to note that >15% is a “greater than” value, so there’s room for surprises yet. We’ll have to wait and see how the chips perform in the real world.
AMD likes to tout its performance per watt leadership, and so it should. The company expects its 16C/32T model, likely to be named the
