AMD's upcoming Ryzen 4000 series processors will be based on the company's Zen 3 design, which will feature a deeply revised architecture aiming to offer increased performance (surprising no-one). AMD themselves have already said that Zen 3 will offer performance increases in line with the reelase of new architectures - and we all remember the around 15% increase achieved with the release of Zen 2 Ryzen 3000 series, which surprised even AMD on its performance capabilities. Several sources around the web are quoting an around 17% increase in performance, taking into account increased operating frequencies of Zen 3 (100 to 200 MHz at least for the enterprise solutions, which could pave the way for even higher increases in consumer-geared products) and increased IPC of its core design. The utilization of EUV in the 7 nm process shouldn't have much to do with the increased frequencies of the CPUs, and will mostly be used to reduce the number of masks that are required for production of AMD's Zen 3 CPUs (which in turn will lead to increased yields).

Sources are claiming an increase of up to 50% in Zen 3's Floating Point Units (FPU) compared to Zen 2, while integer operations should make do with a 10-12% increase. Cores should remain stable across the board - and with that increase in performance, I'd say an upper limit of 16 physical and 32 logic cores in a consumer-geared CPU is more than enough. Increased IPCs and frequencies will definitely make AMD an even better proposition for all markets - gaming in particular, where Intel still has a (slightly virtual) hold in consumer's minds.
