In an interview with Dr. Ian Cutress of Anandtech, AMD's CEO, Dr. Lisa Su, told that their CPU teams are fully focused on their next-generation Zen 4 and Zen 5 core architectures while the GPU team is currently hard at work on developing the RDNA 3 architecture.

Lisa stated that their CPU division working on Zen cores has done a phenomenal job but the best is yet to come. AMD's next-generation Zen 4 and Zen 5 core architectures are already being prepped & will be extremely competitive.

‘Mark, Mike, and the teams have done a phenomenal job. We are as good as we are with the product today, but with our ambitious roadmaps, we are focusing on Zen 4 and Zen 5 to be extremely competitive.

AMD's Rick Bergman on Next-Gen Zen 4 Cores For Ryzen CPUs

Q- How much of the performance gains delivered by AMD’s Zen 4 CPUs, which are expected to use a 5nm TSMC process and might arrive in early 2022, will come from instructions per clock (IPC) gains as opposed to core count and clock speed increases.

Bergman: “[Given] the maturity of the x86 architecture now, the answer has to be, kind of, all of the above. If you looked at our technical document on Zen 3, it was this long list of things that we did to get that 19% [IPC gain].Zen 4is going to have a similar long list of things, where you look at everything from the caches, to the branch prediction, [to] the number of gates in the execution pipeline. Everything is scrutinized to squeeze more performance out.”

“Certainly [manufacturing] process opens an additional door for us to [obtain] better performance-per-watt and so on, and we'll take advantage of that as well.”

We know little about Zen 4, let alone Zen 5, right now but the architecture promises to be a huge deal for the consumer and server segment. The Zen 4 architecture is positioned to launch in 2021 and Ryzen CPUs based on the architecture would be the first to get support on a brand new AM5 platform which will offer next-generation DDR5 & USB 4.0 support.

In addition to the platform, AMD is also looking into increasing the core counts of each respective CPU lineup. Currently, the AMD CPU family scales up to 64 cores on servers & high-end desktop, 16 cores on mainstream desktop, and 8 cores on mobility platforms. This has been the case since Zen 2 and Zen 3 generations. Going forward, we would get to see more cores, presumably 96 cores for server/HEDT, 32 cores for mainstream desktop, and 12-16 cores for the mobility segment. It will be possible due to the smaller process node and design changes that will allow AMD to feature more CCD/CCX units in their next-generation Zen offerings.

‘There will be more core counts in the future – I would not say those are the limits! It will come as we scale the rest of the system.’
