Only tagging this because it didn't age well
It didn't? Do we need 32GB or 8k? I don't think so. Not for gaming. Maybe for Deepseek/LLM.
The most I seen with my 4090 ,is 22GB , that was Harry Potter , but since then more and more of games are up there .
There are MANY games this is the case...I get the impression it's what needed for 1440p textures at 4k. I would in-fact say that 22 is a good way to think of the future we're headed towards:
~22GB for games (at high-end settings)
~22T for a CPUs (because this is an efficient use of a cpu). A topic for a different day.
You'll understand why it's ~20-23GB and not 24GB in a second.
Like I keep saying:
24GB: 4090; kinda the standard for 4k or 1440pRT 'high'->4k upscaling.
18GB: Kinda gonna be the standard for 1440p or 1080pRT 'high'->1440p/4k upscaling
16GB: Kinda the baseline for the future. Probably the base for many standard RT games and/or 1080pRT 'low' settings->1440p/4k upscaling; may or may not survive 1440p (in all instances).
You can calculate this out to roughly 'up to ~90TF', ~60-68TF, ~45-60TF. The scale is important because the bottom is for base resolution, the top-end for up-scaling (and/or RT).
PS6 will probably be on the threshold of 16/18GB, and have instances where both could be needed. Figure the average system ram usage is ~14GB (for a high-end game), which I'm sure many have seen in games.
Obviously some games could use less system ram and more for the inherent textures (say ~6/22 give or take), especially if the 'core' is based on this generation of consoles (a la a HD/RT remaster).
I'll give you another way to think of it:
Say a (typical) high-end game with everything turned up uses 45TF; add another ~20-25% for RT for ~53-56TF, which is not completely unusual.
Now apply DLSS3/FSR4 for a (around ~8%) perf hit. DLSS4 requires ~15%. This output would require ~60TF, or the approximate limitation of 16GB.
(Obviously not all games use all things, sometimes 45TF is the threshold for certain things, etc, and that 16GB could be used solely for pure rasterization and/or you don't need to use those features.)
This is my estimate for the PS6....perhaps something like 11264 @ 2700mhz (give or take?)...Because it fits the trend we're seeing perfectly.
This perf hit from up-scaling is also the difference between the usage of ~20+ - 22+GB from 24GB bc not all compute is being used for the game scenario (it's the difference from upscaling overhead).
This is why you see this very common theme, I think.
Numbers are not
exact, but hopefully you catch what I'm putting down. Like I said, it's pretty apparent in games already (45TF/>12GB and will soon want 60TF/16GB+ for the common desirable scenario).
It's also how you can calculate how N48 (unless it overclocks pretty high in terms of clock/memory) may not age well for upscaling/RT, while 4070ti/5070 (<45TF/12GB) are living on borrowed time.
This is why 9070/9070xt should be cheap, why 12GB cards well...
they just are.
Really hoping AMD explains this stuff with (explaining the segmentation of) N48, because I think all the variables confuse a lot of people. Base resolution, upscaling types, RT, FG, WTFBBQSAUCE.
Point is, I don't expect anything below a overclocked 9070xt and/or 9070xtx to live very long in the way most people want to use them (1440p, 1080pRT->1440p/4k 'low/standard' RT upscaling).
IOW, anything below a 4080/5070ti from nVIDIA...but even those don't exceed 60TF and could be limited by 16GB buffer. You can see how they're on the cusp (this is how planned obsolesence works).
For high-end gaming, that is, and not factoring in FG (because I wouldn't suggest using it below 60fps). Obviously people can enjoy whatever games and any game however they see fit and/or can afford.
Again, this is why I hope the LOW-END on 3nm is 16GB/45-60TF, Lower-mid 60-~70TF/18GB, higher-end up to 90TF/24, and halo whatever they want because ain't nobody probably going to buy it.

Which brings me full circle. Do we need 32GB? I don't think so. Will they make 32/36/48GB over the next few to several years? Probably; native 4kRT. Do I think most people will want/need them? No; upscale.
