Single Threaded Performance vs Multi Threaded Performance; Which is more important in 2023? (alien.top)

For much of the 2010s, we were stuck with mainly dual-core and quad-core CPUs in PCs. However the arrival of Ryzen shook the PC industry, causing a rapid increase in core counts. At the time, there was fervent discussion on this matter, with many questioning if more cores were worth it, and how many cores are more than enough?

So how do things stand today? The latest Intel and AMD consumer processors top out at 24 and 16 cores respectively. What extent of modern software can take advantage of all those cores? What modern workloads are still bottlenecked by single threaded performance?

Gaming still heavily prefers single threaded performance.

People keep saying this, but does it tho? I've seen multiple benchmarks where 8 slower cores are faster than 6 high speed cores. I would say cache is more important that single threaded performance in 2023.

That just isn't true. I don't know what benchmarks are you watching but you won't find a single game where Ryzen 7 3700X is faster than Ryzen 5 5600(X).

Same goes for 5800X vs 7600X. On intel's side it's harder to compare because higher core count CPUs have more cache.
