Right now, consoles have 16 GB unified memory. Some of that is allocated for the CPU, some for OS resources. Most of it can be used as video memory at around 448 GB/s bandwidth.
Using simple math: the factor 0,75 of the total RAM in the current gen console RAM is the VRAM you need on the PC side to have a great experience, while the factor 0,5 is the bare minimum.
On the PC side, 12 GB VRAM is plently for current gen games, while 8 GB VRAM is the minimum.
You can tell this formular works by applying it to the older console generation:
PS4: 8 GB RAM. 8 GB x 0,75 = 6 GB VRAM on the PC side. 6 GB VRAM was more than enough, while 4 GB VRAM was the minimum in many late gen titles.
Now, let's use the same calculation on a hypothetical PS6 with 40 GB RAM... And that is 20 GB at minimum, 30 GB VRAM for smooth sailing.
This means, any GPU besides the 5090 will not be able to run true next gen games at comparable visual quality settings to the PS6, simply because Nvidia has been very stingy with VRAM.
Even if we take the handhelds into account, 36 GB RAM x 0,5 -> you would need 18 GB VRAM to run true next gen games decently. These handhelds still have vastly more memory bandwidth than your usual DDR5 setup (80 GBs vs 200 GB/s).
Now, there's a possibility the rumors are BS and consoles are just going to have 24 GB RAM. In that case, 16 GB VRAM would be plenty. But what about all the 8 GB GPUs Nvidia released? And what about expensive 12 GB VRAM becoming the bare minimum of next gen games then?
I think Nvidia really fucked up badly here. Sadly though I almost suspect when cutting edge next gen games release and games won't run well on these GPUs, people will just blame bad optimization instead of recognizing it is Nvidia who sold them insufficient GPUs.
Edit: since many people only read the OP, listen carefully:
I'm not talking about PC gaming as a whole here. Obviously the PC platform is going to evolve, obviously the PC GPU that releases after the PS6 launch is going to beat the hell out of PS6.
I'm talking about PC gamers who bought a RTX 5070 or RTX 5080 right now and expect it to do well for next gen games. THOSE PC gamers MIGHT be in trouble IF, and only IF, the PS6 is going to have more than 24 GB unified memory! For cross gen games, on max settings, for next gen games at lower settings, even.
I'm not talking about PC as a whole, this is no console people vs PC people war bullshit. Sorry for the misleading thread title.
