AMD demonstrates Ryzen 7000 Zen4 CPU reaching 5.5 GHz while gaming - VideoCardz.com

I'm not too surprised, although I'm a bit confused why AMD isn't going into the added detail that would alleviate some of the confusion. That same slide advertises vaguely that we are getting an unknown number of new instructions. So you might see a ~15% single threaded performance improvement for the AVX vector math workloads every CPU made in the last decade is capable of but you then also have whole new categories of math the core is now natively capable of that isn't easy to compare against the previous generation. Due to not being able to easily communicate what was improved or added and why it matters, you have end users all freaking out a bit trying to figure out why there is all this extra silicon being used but not the performance uplift they expected to be announced.

Because it's labeled "AI instructions" we can assume it's not just referencing the AVX512 support everyone is expecting but something similar to matrix, bfloat16, or int4/8 instructions. The industry hypes these types of improvements with buzz terms like "AI acceleration" but really it's just the ability to do new types of math natively on the hardware.

Intel has also be running into this problem in communicating these types of improvements to the average user because it is normal a new type of performance that doesn't easily compare to previous generations because the feature didn't exist in previous generations. Even though these new instructions normally result in a major performance uplift for certain workloads you can't just say "x% performance improvement over previous generations" because the previous generation lacked the new type of hardware acceleration. This has resulted in Intel containing outlets like ServeTheHome asking them to figure out then publish benchmarks showcasing how all these new instructions (aka acceleration) offer performance uplifts in typical computing activities.
