AMD Ryzen 8000 CPUs could bring up to Core i9-13900KS-level boost clocks, 25% more L1 cache, and double-digit IPC uplift vs Zen 4

The first batch of Zen 4 AMD Ryzen 7000 CPUs released in September 2022. Since then, a boatload of leaks and rumors have surfaced regarding the upcoming Zen 5 Ryzen 8000 processors. For instance, we reported last month that the Zen 5 CCDs are codenamed “Eldora” while the individual cores inside the CCDs are termed “Nirvana”. Now, a leak from RedGamingTech seems to confirm much of what we have already heard while revealing a few new crucial details.

For starters, the leaker reports that a max core count of 16 and 8 cores per CCD appear final. Zen 5 could also stick to SMT-2 which is in line with the leaker’s previous Ryzen 8000 leak.

Whereas Paul only mentioned “a larger L1 cache” last time, the leaker now shares that Zen 5 could bring a larger 80 KB L1 cache per core vs 64 KB L1 for Zen 4. The 1 MB L2 cache per core and 32 MB of L3 per CCD remain the same as the Ryzen 7000 chips.

Moving on to power consumption, Paul reports that Zen 5 will have a default TDP of 170 W which is the same as the current Zen 4 flagships, the Ryzen 9 7900X and the Ryzen 9 7950X.

Finally, Zen 5 CPUs will supposedly boost up to 5.8-6 GHz which is up to 300 MHz more than the Ryzen 9 7950X which has a boost clock of 5.7 GHz. The leaker also alleges an IPC gain of 19% on average.

As always, take this preliminary information with caution as the final Zen 4 product could be significantly different.
