Leak suggests AMD Zen 5 CPUs to pack impressive IPC performance gains and hugely increased core counts
AMD’s next-gen Zen 4 “Raphael” CPUs are slated to launch in the second half of 2022. But this hasn’t stopped leakers from revealing details about Zen 5, the CPU architecture that will succeed AMD Zen 4 processors. Confirming a previous leak by Moore’s Law Is Dead, RedGamingTech has suggested that “AMD are actually more excited about Zen 5.”
According to RedGamingTech, Zen 5 chips are expected to adopt a hybrid architecture just like Intel Alder Lake CPUs with a mixture of power-saving Zen 4 cores and speedy Zen 5 cores. However, AMD’s top-of-the-line Zen 5 desktop SKUs like the Ryzen 9 processors won’t pack any Zen 4 cores and will only have performant Zen 5 cores. Reportedly, Zen 5 APUs that will be used in laptops and low to mid-end systems may have Zen 4 cores.
For performance, RedGamingTech reports that Zen 5’s IPC gains are bigger than Zen 3 to Zen 4. The leaker puts the number at 30% for single-threaded workloads. Furthermore, core counts for AMD Ryzen 8000 chips are reportedly going to double. Flagship parts, for example, will have up to 32 cores.
AMD is also looking to introduce some big changes to the cache in Zen 5 processors. Per RedGamingTech, due to architectural changes L1 cache will be significantly increased. L2 cache will also allegedly see a big change and will be unified across the CCX.
Finally, the L3 cache will see a huge change as it will be stacked so all the core clusters can access it, resulting in reduced die size and lower latency.
As with all the leaks, none of the information presented here came from official sources, so take it with a huge grain of salt.
