Packed AMD Zen 5 leak reveals Ryzen 8000 CPUs could release in Q1 2024 with 20-25% IPC uplift, up to 16 cores, and larger L1/L2 caches
As we move deeper into the Zen 4 Ryzen 7000 CPU generation, more rumors regarding the next-gen AMD Zen 5 processors are making rounds on the internet. This time both RedGamingTech and Moore’s Law Is Dead have shared information about the Zen 5 Ryzen 8000 chips scheduled to be launched next year.
According to MLID and RedGamingTech, Zen 5 has been designed for both TSMC 4 nm and 3 nm processes. The 4 nm process will allegedly be used to manufacture desktop “Granite Ridge” CPUs alongside some APUs, while the smaller 3 nm node could be reserved for “Turin” server processors and the specific APUs.
When it comes to core counts, both MLID and RedGamingTech report that the desktop Granite Ridge Zen 5 chips will be limited to 16 cores and 32 threads. MLID adds to this by stating that AMD could “launch a 32-core Zen 5c model if they want to”. Speaking about the launch, Tom suggests that Zen 5 could release in H1 2024, possibly Q1.
Moving on to the performance improvements, Paul maintains that Zen 5 will have an IPC uplift between 20-25% with one of his sources mentioning “over 25%” for single core. Tom’s report seems to confirm these numbers but adds further nuisance by suggesting Zen 5 “will increase IPC over Zen 4 by at least 15%”. Again, both leakers share the opinion that it is much too early to talk about core clock increases but MLID sees Zen 5 could have a frequency boost of between 2-9%.
So, where does the proposed IPC increase come from? Per MLID, the IPC uplift is the result of “cache increases, a wider front-end that can dispatch more instructions simultaneously, and a back-end with more resources”. Paul shares similar information and expounds that Zen 5’s L1 and L2 caches are both larger than before while the L3 cache “also sees some changes”.
Finally, RedGamingTech and MLID are also on the same page regarding the design of the desktop Granite Ridge and mobile “Strix Point” APUs. The leakers share that Team Red will outfit the Ryzen 8000 desktop chips with only big Zen 5 cores while the Strix Point APUs will see a big.LITTLE design with big Zen 5 and smaller cores.
While RedGamingTech and MLID are prolific leakers, they have been wrong in the past. So, take the information presented here with caution.
