just goes to show how far ahead Cerny really was. this is an even bigger deal than 8GB GDDR5 which also took a while to become standard on mid to high end PC GPUs because the PS4 only had 5 GB of VRAM available for games and some of it was used for system ram which PC games have an abundance of.
This is almost 11 Zen 2 Cores of performance that they will need dedicated hardware for. Anything is possible, but I think cerny deserves a lot of credit for designing something that is years ahead of anything in the PC space and for only $399.
Meanwhile PC owners have to wait for RTX I/O and Direct Storage. But even then it will take some time for the public to adopt the technology. It's not like you can flip a switch and obtain all the I/O benefits that the PS5 has. And even after people start to adopt the technology HDDs will still be used by a lot of gamers on PC. Maybe not you're enthusiast's but certainly many average Joe's will be stuck with HDDs. Might take some time for SSDs to become part of the minimum requirements.
