PlayStation 5 is faster than some graphics cards
Woah, really?
That article is one of the worst of its kind and I've been seeing them pop up since the 90s, that dude just copy & pasted a bunch of speculation, went to the Era school of understanding Teraflops and barfed out some words to connect all the numbers without bothering to make reasonable arguments.
Also, considering 95% of modern console's innards are basically PC hardware (plus secret sauce which can make a difference, not denying that) and PC gaming is playing a big part in helping to drive that hardware forward inbetween console cycles, especially graphics chips.... is that something anyone should want? Even the most fervent console zealot imaginable must realize the longterm impact on AMD if suddenly no PC gamers would exist anymore to buy their high end consumer CPUs, or Nvidia trying to sell its 3080Ti Superduper to Excel wielding accountants. I know these companies have other avenues and motivations for innovating, cars are a big thing for Nvidia for example, but gaming has specific requirements that need to be catered to. Doubtful Zen 2 would be this good without AMD trying to match Intel's performance in games specifically. So even if you truly, deeply hate everything PC it'd be in your best interest that we stay around and keep paying stupid money for new tech. Other way around too obviously, both markets complement each other nicely.
The question of consoles surpassing PCS keeps coming back.
That's a very different question compared to 'Can PS5 kill the pc gaming industry?" though.
With all the new tech about to be made mainstream (SSDs, hardware raytracing, strong CPUs,etc)
SSDs aren't new tech, not even NVMes, they've been mainstream on PC for easily half a decade now, Windows 10 doesn't even run right if installed on an HDD and lots of people have them. Same for strong CPUs, sure the new stuff is great but a good Intel processor from a few years ago will be able to keep up for sure. Graphics cards are imo really the only component where the mainstream might be forced to upgrade to keep up with new consoles and even there folks could be in for a rude awakening, who knows, like maybe the raytracing implementation turns out to be very basic, inefficient and quickly outdated. Same goes for that superfast storage, who knows how much of that we'll actually get and how it'll work exactly.
In two years, every pc might need an nvme pcie4 to play modern games.
So PCIE3 SSDs will become insufficent for playing games by 2021 because they can only deliver 3,5GB/s instead of 4,5GB/s? No, I don't buy that nextgen will get magical drives that'll max out PCIE4 or that games in development now will not only make use but require that additional speed. I know, new gen, time for pie in the sky dreams and buzzwords while ignoring the realities of tech, game development and cost, but some reason should always be applied.
