The highly anticipated Zen 5 architecture from AMD is set to release in 2024, and rumors about its specifications have been making rounds in the tech community. Paul from RedGamingTech has recently leaked updated information about the Zen 5 architecture, which has created a buzz in the tech industry. According to Paul, Zen 5 could bring significant improvements over the current Ryzen 7000 Zen 4 chips, including a double-digit IPC uplift, larger L1 cache, and a possible shared L4 cache for APUs.
Double-Digit IPC Uplift
Paul claims that the Zen 5 architecture could bring IPC gains of up to 30% over the Ryzen 7000 Zen 4 chips. Although he later revised the average target to 25%, he now mentions a range of 22-30% IPC improvement. The actual IPC uplift will be revealed when AMD officially launches the Zen 5 CPUs next year.
Eight Cores per CCX
The Zen 5 architecture is said to have eight cores per core cluster (CCX), which will bring significant performance improvements over the current Ryzen 7000 Zen 4 chips. According to Paul, the Infinity Fabric hasn’t been improved, which is why scaling issues are preventing Zen 5 from having more than eight cores per CCX. This means that the Ryzen 8000 Zen 5 CPUs will have up to 32 cores, spread across four CCXs.
Larger L1 Cache and Unified L2 Cache
The Ryzen 8000 Zen 5 CPUs will reportedly have a much larger L1 cache than the current Ryzen 7000 Zen 4 chips. The L2 cache will also be unified across a CCX, which will bring significant performance improvements. However, Paul now thinks that the L3 cache will either be shared by all core clusters or work as usual. In the second case, there could be an “MCD shared” L4 cache, but it will only be for APUs.
Overall, the information leaked by RedGamingTech about the AMD Zen 5 architecture largely echoes the rumors circulating in the tech community. While we won’t know for certain until AMD officially takes the wraps off Zen 5 CPUs next year, the prospects of a double-digit IPC uplift, larger L1 cache, and a possible shared L4 cache for APUs have generated a lot of excitement among tech enthusiasts. The Zen 5 architecture promises to bring significant performance improvements over the current Ryzen 7000 Zen 4 chips and could give Intel a run for its money.
