AMD's upcoming Zen 5 CPUs predicted to be the biggest upgrade since the original Zen chips

pcgamer.com:

AMD's next-gen Zen 5 CPU is shaping up very nicely. Well, it is according to the latest rumours which indicate the new CPU design will crank out roughly 30 percent more performance than AMD's existing Zen 4 architecture, as used in Ryzen 7000 Series chips like the Ryzen 9 7950X. That would make Zen 5 the biggest ever upgrade since the original Zen CPUs arrived back in 2017.

The latest purported data dump comes from YouTube channel RedGamingTech. A number of rough performance estimates for multiple core configurations are provided. 

According to the channel, the 16-core variant of Zen 5 will knock out around 49,000 points in the multi-threaded run of Cinebench R23. That compares with the 38,000 points that the Ryzen 9 7950X achieves. Similar uplifts are claimed for 12, eight, and six-core configurations. 

So, yeah, explicit in there is that the core counts aren't expected to change for Zen 5. As for single-threaded performance, results in the mid to high 2,000s are predicted. Existing Ryzen 7000 chips can return just over 2,000 points at factory clockspeeds. So, those numbers are in line with the 20 to 25 percent IPC or instructions per clock increase predicted for Zen 5.

Overall, then, Zen 5 is being mooted as an even bigger step over Zen 4 than Zen 3 was over Zen 2, the latter being the biggest generation-on-generation leap AMD has managed with its Zen chips thus far.

Speaking of IPC, that's where pretty much all the performance is coming from with Zen 5. RedGamingTech says that there will be very little by way of clock frequency gains, perhaps an additional 200MHz.

What's more, all of this very much aligns with previous indications of Zen 5's performance. Back in April, we reported on a presentation from Tenstorrent's
