There's also a general industry slow down in terms of progress. We simply aren't really going to be seeing >2x improvements every 18 months (roughly) for the same cost compared to over 10 years ago. This likely will mean PC components won't have the same "pace" to out grow the consoles from a cost perspective compared to the past.
On the GPU side of things, its looking like at launch AMDs own gpus will be more then twice as fast as the consoles (around 25TF vs 10 for ps5), with more memory to play with aswell at 16GB just to vram. Im talking AMD and normal rendering there. That's a rather huge difference.
Taking NV into account, they are atleast in the same performance area regarding raw performance as AMD, probably faster at the highest end of products.
Then we can take ray tracing into account, the biggest and most important graphical difference as compared to previous generations, just about every next gen game seems to be in that. Here the pc is already ahead too, with the consoles said to be being on Turing level (2060 at that) in that regard.
DLSS should not be forgotten imo, as it really does alot to performance if you can enable 4k gaming with 1080/1440p requirements.
That's now, at the very beginning, or even before the consoles even launch.
Zen3 is here and it has a rather large IPC improvement, already a generation ahead there, Intel will answer and AMD will try to compete. Dont forget much higher clocks too, which is still important in special in higher refresh rate gaming.
Regarding storage and IO, consoles might have an advantage, probably the PS5 there. But then, if we believe that MS/NV didnt straight out lie and being corrupt and other conspiracy theories aside (not that the topic for that), they claim 14GB/s, atleast very competitive with whatever the consoles have. The new optimized DMC game loads about as fast on PC, not bad.
I think Optane is more for a latency monster then speeds. Also dont forget PCs usually have something called system ram, which still is faster then any SSD in about every way.
With Xbox being PC basically, as MS sees it, software implementations also seem much better then say ten years ago. VA and DX12/vulkan made their entrance and i assume will improve even more so. Seeing how well old pc hardware from 2012/2013 has held up, much better so then during 6th and 7th generations, i dont see this declining.
A 3060 equiped pc, with matching cpu and other components will tag along just fine. Hence the reason Alex is planning to use a 3060 as his comparison to PS5 setup.
So yeah, gap is already rather big for being the time frame, and things will only evolve over time, in special with AMD and NV competing so much, Intel joining the party and MS seeing the pc as more important then before. Things are moving fast, 2021/2022 and we see even faster RT and improved DLSS solutions, besides increased normal render capabilities.
AMD jumped from 10TF 5700XT to 25TF in one generation. NV went from 16TF 2080ti to 36TF 3090. GDDR6 to GDDR6x and close to 900GB/s BW. Zen3 huge IPC improvements. RT improved what, 200%? Stagnating hardware, nah
Prices will go down obviously, fresh new hardware never has come cheap in the pc space. We have seen NV atleast going the better route atleast with Ampere. That and consoles have gotten more expensive too, even for games itself.
Will texture packs die off for "new console games" henceforth?
Modding on pc will probably never die off. Some games are transformed alot by it, GTA, RTX quake, skyrim, even ray tracing for vice city has been done. Texture packs fall into that same category for the most, they often go hand in hand with modding/improving graphics for games. Its one of the reasons people play on pc, aside from the many other reasons.
