AMD will turn all marketing to focus on mobile chips (around 80% of marketing expenses). AMD will restrict features for entry level and mid level chipset very similar to Intel offerings.Motherboard prices will jump 25-45% due to components inflation and chipset price.CPU prices will jump around 30-50% for same positioned model in lineup.AMD now has severe thermal issues, test chips can't reach even 3.5Ghz without thermal damage.TSMC have major issues with performance version of 5nm process (now only low power version is offered).AMD can restrict usage of external USB controllers and can ask for special license payment for such use.Chip will offer dual channel DDR5 support, AMD still having issues with memory controller.Cache size can increase by around 50-75%.Core counts per chiplet won't increase and will stay at 8 cores.Performance per core increase will be below 4% and can be even negative.While all of these, individually, would be impressive, taken together they could end up producing a massive performance improvement over AMD Zen 3 and whatever Intel has planned for its Raptor Lake processors, which are expected to be released around the same time. There's also talk of core frequencies of 5.0GHz for all cores, regardless of how many AMD ends up using in its next-gen processors. We may see as much as a 25% boost in AMD Zen 4's IPC performance and, if AMD sticks with PCIe 4.0 for Zen 4, four additional lanes, 28 from the current 24. More recently, this jump in power has started to come into better focus, with performance gains as large as 40% over its current gen processors being batted about online. 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.
