That's nearly double the density over Zen 3, which would imply some serious performance gains from this improvement alone. This could bring as much as a 1.87x transistor density improvement over the TSMC 7nm process used in AMD Zen 3. The most obvious improvement in performance is going to come from AMD Zen 4's move to a 5nm process. (Image credit: AMD) AMD Zen 4 performance There's also a lot of talk about AMD Zen 4 chips introducing integrated Navi graphics, which would be a major coup for Team Red as it would seriously beef up the graphics capabilities of its Zen 4 APUs, something that is sure to be popular with more budget conscious consumers and builders. This 3D architecture technique isn't just for cache though, and there's little doubt that these kinds of innovations will start being introduced in Zen 4. Recently, AMD debuted a 3D chiplet technology in a prototype Ryzen 5950X chip that greatly expanded the available CPU cache for the processor, which alone provided the kind of performance gains normally seen with leaps in processor generations.

There is a very strong expectation that AMD might be aiming for a higher core count with Zen 4 though, going as high as 24 cores for its consumer processors and even suggestions of a 128-core/256-thread behemoth for its EPYC server CPU. There isn't a lot that we know about AMD Zen 4, at least not officially, beyond the fact that it is using TSMC's 5nm production process. Su gave a pretty strong indication that it will. While DDR5 will be supported in Zen 4, we don't know officially if PCIe 5.0 will be, though Dr. This is especially true since AMD Zen 3 doesn't have DDR5 or PCIe 5.0 support, while Intel Alder Lake will. In 2021, it hit relative desktop market share parity with Intel for the first time in 15 years, so stepping off the field as it were for that long might be the opening Intel needs to get its footing after a few tough years. Still, a whole year without a competing step up in processor generation sure looks like a gamble on AMD's part. The success of Apple's M1 chip hasn't seemed to change that stance, at least not officially. This will puts AMD Zen 4's release nearly a year after the launch of Intel Alder Lake processors, something that should concern AMD – though the company has openly dismissed Intel's turn towards big.LITTLE processors as a technology in search of a purpose outside of mobile devices.

Where to buy AMD Ryzen 5900X and 5950X: who has stock?.Mobile chips will probably be several months after that, and it's not known when EPYC server chips can expect a Zen 4 upgrade. Su said that AMD Zen 4 chips will start rolling out in the second half of 2022, starting with the Ryzen 7000-series desktop chips. During the company's keynote at CES 2022, Dr. We do have a more firm release window now, however.
