CPUs based on AMD's new Zen 4 architecture won't arrive until this fall, but the company is already dropping hints about what comes next. As reported by AnandTech, AMD is planning a new Zen 5 architecture, which is currently scheduled to come to both desktop and laptop PCs sometime in 2024. The company is also planning to bring the Zen 4 architecture to laptops in 2023, while the desktop CPUs remain on track to launch in 2022.
AMD also provided more information about Zen 4's performance. The company said at Computex that the Ryzen 7000-series chips would sport roughly 15 percent faster single-threaded performance than Ryzen 5000. The company said today that Zen 4 was between 8 and 10 percent faster than Zen 3 at the same clock speeds, accounting for most of the speed improvement, while the remaining 5 to 7 percent will come from higher clock speeds for Ryzen 7000 CPUs. Zen 4 can also deliver roughly 25 percent higher performance-per-watt than Zen 3.
3D V-Cache will make a return in some Zen 4 chips, though it won't be available in all of them. (credit: AMD)
The company will bring back its 3D V-Cache technology for some Zen 4 CPUs as well. This allows AMD to stack additional L3 cache on top of the CPU die, providing a big boost to the amount of cache without increasing the footprint of the CPU die or the CPU package. As we saw in our review of the Ryzen 7 5800X3D, the technology does help with game performance in particular, though the chip also ran a bit hotter than Zen 3 CPUs without 3D V-Cache, and its somewhat lower clock speeds made it perform a bit worse in non-gaming workloads.
