I expect Zen 4 with 3D cache to continue to trounce alderlake just like zen 3 5800x3D does in workloads that the ultra high speed cache takes advantage of.
Zen 5 is likely to keep intel on their hind legs, but by that time, intel might actually have proper chiplet/parted designs incoming to consumer level systems.
I just can't see a Zen4 32 core 64 thread chip even coming close falling so far short of absolutely decimating 13th gen intel offerings
Here's how intel improved ipc on their last gen cpus:
1: ipc gains.. specially since their prior chips have been basically minimal in improvements at all. Much of the performance can be attributed to the fact that they are pushing clocks as high as possible at their disadvantage
2: big little is In my opinion not a great idea for desktop systems, the concept had been around for ages, but intel frankly had no hope of building a proper high performance core count since they were already eating power and spitting fire. Basically 10 year old non SMT cores utilizing the high density node paired with proper newer architecture cores. Still basically a monolithic design
3: True 10nm.... but grossly inefficient.
4: Much of their performance is leverages through specialized supported instructions, cases like matlab for example are quite common still.
Intel has made endless promises and fail to keep to them. I'll believe it when i see it.
In the meantime, Zen 4 is only IO and underlying node changes for the most part with the socket change. It's basically Zen 3+... with ddr5, PCI-E v5.0 and the I/O die being an apu basically. Oh and the REAL possibility of a 24 and 32 core cpu only solution on consumer desktop. Considering the tdp increase options.
The 5800x3D is absolutely destroying intel in everything though right now. I expect Zen5 to utterly ruin intel... Just like Epyc 2 has been ruining intel since it's launch.
