Data can be made to say anything you want it to be just altering how it's presented. Plus most people, including reviewers, do not understand how VRAM works in the first place and end up jumping to wrong conclusions. Watchers, also not understanding, eat up those conclusions and thus internet memes and myths get born.
Going to compare the 4060 Ti 8 vs 16GB because it's a perfect sample case. Both cards have identical GPUs with identical compute, power, everything. The only difference is the 8GB has the four VRAM chips operating in full node, while the 16GB has the eight VRAM chips operating in clamshell half mode.
Here is Stalking 2 at 1080p ultra/epic
Same game at 2160p ultra/epic/whatever
That is what a VRAM failure look like. Those 8GB cards are having to flush their VRAM resource cache to load new resources from system RAM mid-frame resulting in performance falling off a cliff. Of course we're looking at sub 30FPS play here on these cards so it doesn't really matter.
Toms take on The Last of Us, 1440p ulta/whatever
Same average but notice the 8GB has a slightly lower "lows", that's because it has to occasionally flush VRAM resource cache, not often but enough to effect the chart.
Same game but at 2160p
Now we are starting to see VRAM matter, performance isn't crashing hard but the game is having to flush resources often enough to actually make a difference. Of course I wouldn't call low 20's FPS "enjoyable" anyway, the 5060 TI 16GB isn't looking much better at sub 30FPS. Like Stalker 2 the 16GB cards aren't playable either at this setting.
And just for reference, Jarred was kind enough to do a 1080p medium on all these games.
Wow actually playable on a 60 class card. This tells me that we could of likely gone to 1440p high and been ok on both the 8 and 16GB cards.
This type of analysis is what all the outrage farming reviewers are missing. There are very few times when a card on a 128-bit memory bus is going to be "good" at 16GB but "bad" at 8GB. The same situations that are playable on that 128-bit memory card are ones where having extra VRAM isn't going to make much difference in the first place. The situations that you need more then 8GB aren't playable on that 128-bit card to begin with. The only two choices are changing the situation (reducing settings) or upgrading to a proper 192-bit and above card.
Seriously, my Nvidia Geforce 4200 TI AGP I used in my retro gaming rig has a 128-bit memory bus. Anytime you see a 128bit memory bus, immediately assume that card is bottom tier and should be avoided if at all possible.
Here are all the charts Jarred did, it paints a very good picture.
