VRAM - AMD/Nvidia, why does it differ?

[MooMoo444]

Why are AMD always so generous with VRAM and nvidia so conservative?

I mean 3Gb is very borderline for some games at 1080p, and actually not enough for some at 1440p.

those resolutions are no problem for 290/290x with 4Gb, so why are nvidia always holding back in that regard?

If you take another of their "top end" cards, the 580, 1.5gb was arguably not enough at release, let alone shortly afterwards.

I know someone will probably mention how 'generous' they were with the Titan, but that's not exactly a card aimed at everyone and was more of a peen flexing exercise by nvidia than an actual sensible card release.

I already pointed out the Titan is an outlier and shouldn't really be considered. It's completely unrealistic and out of 99.999% of peoples price range.

I am simply comparing what you get for your money at the £350-550 price bracket.

The RAM roughly correlates to the RAM usage of the settings that card can run.

That wouldn't make sense though, otherwise in reality nobody would ever bother with SLI or CF.

What VRAM sizes are we likely to see on the next gens? 6 from Nvidia and 8 from AMD?

doubling each major jump seems to be the norm.

I ran out of VRAM frequently on Skyrim with my 770 2Gb. The game would crawl and stutter very frequently. Pauses of 0.5 sec or so. It was the reasoning behind me getting my first 780.

It's probably similar in other games, but it's difficult to break 3 at 1080p. Might have more of a problem when I get my 1440p monitor.

Extra effects (not textures) will indeed increase GPU load. Skyrim itself isn't really demanding on grunt, just texture storage.

"too high framerate" u wot?

Console gamers are so spoilt with low fps
