CPUs based mostly on AMD’s new Zen 4 structure will not arrive till this fall, however the firm is already dropping hints about what comes subsequent. As reported by AnandTech, AMD is planning a brand new Zen 5 structure, which is scheduled to return to desktop and laptop computer PCs in 2024. The corporate can be planning to deliver the Zen 4 structure to laptops in 2023, whereas the desktop CPUs stay on monitor to launch in 2022.
AMD additionally offered extra details about Zen 4’s efficiency. The corporate mentioned at Computex that the Ryzen 7000-series chips would sport roughly 15 % quicker single-threaded efficiency than Ryzen 5000. The corporate mentioned Friday that Zen 4 was between 8 and 10 % quicker than Zen 3 on the identical clock speeds, accounting for many of the velocity enchancment, whereas the remaining 5 to 7 % will come from increased clock speeds for Ryzen 7000 CPUs. Zen 4 can even ship roughly 25 % increased performance-per-watt than Zen 3.
The corporate will deliver again its 3D V-Cache know-how for some Zen 4 CPUs as effectively. This enables AMD to stack further L3 cache on high of the CPU die, offering a giant increase to the quantity of cache with out growing the footprint of the CPU die or the CPU bundle. As we noticed in our assessment of the Ryzen 7 5800X3D, the know-how helps with sport efficiency specifically, although the chip additionally ran a bit hotter than Zen 3 CPUs with out 3D V-Cache, and its considerably decrease clock speeds made it carry out a bit worse in non-gaming workloads.
We did not know whether or not 3D V-Cache could be a function of all Zen 4 CPUs, however AMD’s slide makes it clear that there might be Zen 4 CPUs out there with and with out the additional cache. As with the 5800X3D, the chips with 3D V-Cache will presumably be focused primarily at avid gamers since these are the apps that profit probably the most immediately.
As for the Zen 4-based laptop computer chips coming subsequent 12 months, AMD’s laptop computer processors have at all times been a bit completely different from their desktop CPUs, with monolithic chip designs as an alternative of chiplet-based designs and high-performance built-in GPUs included throughout the board. However their laptop computer and desktop CPU traces have diverged extra lately—Ryzen 6000 laptop computer CPUs mix a 6 nm revision of Zen 3 known as “Zen 3+” and an built-in GPU based mostly on the RDNA2 structure. That may proceed for the Zen 4 laptop computer CPUs, which might be manufactured on a 4 nm course of as an alternative of the desktop chips’ 5 nm course of and can embody an RDNA3-based GPU.
Swapping Ryzen 6000’s RDNA2 GPU for an RDNA3 GPU so shortly reveals that AMD is dedicated to bettering its built-in graphics efficiency. AMD’s Ryzen laptop computer CPUs had been paired with some model of the corporate’s growing old Vega GPU structure for years, and it is good to see that we can’t be saddled with RDNA2-integrated GPUs lengthy after AMD’s devoted GPUs have moved previous it.
AMD additionally shared a handful of GPU-related particulars, confirming a chiplet-based design for at the least a few of its next-gen 5 nm RDNA3 GPUs and scheduling RDNA4 for 2024 (on an as-yet-undisclosed “superior node”). The corporate says that RDNA3 GPUs will present 50 % extra efficiency per watt than RDNA2, due to a mix of the brand new 5 nm manufacturing course of and architectural enhancements.
