If the PlayStation 5 is going to have an 8-core Ryzen clocked at 3.20 GHz as rumored, and 8-core Ryzens in desktop PCs can hit ~4.25 GHz (33% faster) how do you expect games built for 30 FPS on that hardware to run at high frame rates on a PC?
Maybe an Intel CPU with 8 cores running at 5.00 GHz is ~67% faster rather than ~33% faster. That's still only 50 FPS.
Now PCs will be moving toward having more cores - it's speculated that there will be 16-core Ryzen CPUs released this year. If all else stays the same, that should effectively double performance.
That doesn't necessarily help gaming though, if the games are only built to support 8 cores. We still have games released today which are bottlenecked by most of the game logic running on a single core, not even that they don't scale beyond 4 cores.
Anisotropic filtering hits bandwidth pretty heavily, which is why it's not used as often on consoles.
The performance hit is almost negligible on PC most of the time because they have a lot more bandwidth to spare.
That said, it's not zero, and some newer games -especially at higher resolutions- do actually have a noticeable impact. It's why many games only use 8x in their "ultra" presets now, rather than 16x.
I could see something like 4x being baseline on next-gen consoles though, rather than 16x, as it would still be a big improvement over not using any.
