NVIDIA GeForce RTX 5090 Founders Edition Video Card Review

Most of us will get by just fine with a 5080 (or less); honestly this makes the 4090 tempting again as an in-between, if you need more than 16GB of VRAM and don't have >US$2000.

But most of us don't need more than 16GB of VRAM. Yet.

Oh, that's right, I could also use an extra 8gb of vram over the 4090 because AI models like more vram
 
Yep, there's always the argument that a game uses what you have, and it's somewhat still very true. Technically I've got cards with 12GB, 16GB, and 24GB. Most things still play nice all the way down to 12 GB (@1440p-Indiana Jones and Veilguard were the only two games I really had to lower settings for 60+ FPS on this card) and 16 GB(4K-some native, mostly DLSS quality and occasional framegen).

I've seen about a half dozen games that will go over, sometimes close to 20GB, for 4K but those games mostly work just fine on a 16GB card if some things are dialed back slightly. I am seeing more games use more, but it's very incremental, say 1 or 2 per year.

What I find more interesting is that ever since frame gen came into the picture, combined with DLSS quality, VRAM usage can go higher but the extra onboard tech usually enables higher framerates. Used to be if you did manage to load up ~20+ GB of VRAM, it was a slideshow.
 
Steve @ GN did PCIe gen testing on the 5090. Basically you'll see 1-4% difference between PCIe 3.0 and 5.0. With 4% being an outlier.

I know someone else brought it up in another thread. I've been saying it for years where GPU's are no where near saturating PCIe bandwidth.
 
I haven't checked back in on it recently but TechPowerUp somewhat regularly tests PCIe version saturation too. I seem to remember that the 3090 Ti was only just barely beginning to really show a difference for 3.0 and it was in very specific circumstances. I still like to be ahead but anyone still on 4.0 probably has years to go anyway.
