Scene 3 damn near pushing 10GB of VRAM.

It's a Zen1-based CPU that was released 2 years before the PS5 and is easily bested by $100 quad-core CPU's now. If you're going to be comparing relative performance between a modern console and even a 'budget' PC you should use a relatively modern budget PC.
The Zen1 line wasn't even really considered a great gaming CPU upon release, it's main draw was that it was at least competitive and offered more cores for less money. Zen2 is when AMD really got going.
Buffers taking up 6.3GB. Resolution is the biggest hit here. Textures are only 1.8GB. Still large however.
I tried to replicate that third scene above at 1080p. It saved about 800MB on render targets and 1GB on buffers.
I also can't help noticing that the index/vertex buffers remain constant in all these captures. I don't have an explanation for that.

Interesting. Well understandably index and vertex will stay the same; I’m not expecting them to change with resolution. I was expecting render targets to drop a lot more however. But it’s possible that most of these targets are not a full 4K until the very end; so possible a lot of in between resolutions on render targets until close to final output.
I meant that all of those captures report the exact same figures and I've never seen that before. Most of the time these numbers change simply by turning the camera and it makes me wonder whether it could be misreported. But the geometry might also be kept memory resident for raytracing reasons, for example. RT is disabled in these tests but still.
But I was also surprised that the numbers didn't go down more. Render targets often show a roughly 3x increase between 1080p and 4k but I expected the buffers to go down by more than that. I've noticed a bit more PCIe traffic in Sony's ports and it makes me wonder if it's a relic of the unified memory system in their consoles. Graphics memory residing in main memory isn't normally represented by tools like MSI Afterburner and they can be somewhat misleading in that regard.
You are being incredibly insincere here, and intentionally dishonest. I spent hours going through reviews and benchmarks and, to be honest, I don't deserve to be responding to bad faith bullshit like this. Every response of yours ignores the entirety of what you were wrong about.Sure I am, if at this point you still dont get why 2700xt is good hw representstio of ps5 cpu Im done with this subjectyour imagination is stronger than any proofs (btw I post also pure cpu benchmarks without pci infouence but then apparently only reason for results was memory type :d)

Dude chilout, its hw talk and you starting some shit talk about insecure lol :d if you spend so much time analyzing you would just acept fact that 2700xt is very close hw representstion of ps5 cpu, yeah, its just 399$ console, its normal to have little underwhelming cpu, still way above last generation
I have repeatedly said that 2700x trades blows with 4700s benches. I was the first person to say that, when you denied it and falsely claimed that the 2700x was greatly ahead of the 4700s based on benches you clearly were unable to understand. I actually provided the benches that showed this.
You repeatedly falsely represent what I said, no matter the references and quotes I provide about what we both said. No matter how many times.
Your dishonesty is clearly intentional at this point, as you have proved many times now.
It would be interesting to run close to PS5 equivalent settings to get a rough idea how much video memory is allocated on the PS5.
Edit: Ah, the program sadly has no RT support. That's a shame.

People don't change their CPU's any where near as much as they do their GPU and having a CPU that's 2+ years old is common, budget PC's use even older CPU.
I'm still on a 4770k (Until Wednesday next week that is)
Thats because CPU's hadnt so much improvements untill recently. Since Zen3 and the newer Intel CPU's, performance has been increasing rather much. DF has been covering that in one of their Directs i believe. The difference between a 10900 to a alder lake was very impressive.
Add to that until now with last gen and cross gen there has been no real need to upgrade your CPU for non extreme framerates. That's starting to change now with these next gen only games that are starting to release on PC.

His videos are primarily about comparing platforms, and his specific bent is to use them to extrapolate (often incorrectly) on the inherent architectural advantages/disadvantages of each. When your target comparison is a new generation of consoles, you should be comparing with something relatively recent on the PC if you're going to bring arguments about efficiency into it.
Here's something interesting. The highest RT setting seems to double the CPU bandwidth used over no RT while running at the same framerate.
Perhaps this could present an advantage for consoles in some conditions, as barring some kind of limit within the console APUs they should have a lot more CPU memory bandwidth available.
The CPU bandwidth used is certainly at the top end of what a typical DDR4 3200mhz setup would give you. It might be interesting to see how performance scales with faster memory.
Yeah, this might be a good game to look at when Zen 4 and DDR5 land, see if performance gains going to that differ particularly from other games.
Do we know if Spiderman is using AVX2? 256-bit operations seem to be pretty demanding in terms of BW on PC, though on PS5 the situation would be a bit difference as it's got half width vector operations.
