Just a quick question

Hello,

so I was wondering about the specifications of graphics cards, specifically the Core and Memory clock versus the VRAM capacity.

I mean what do you exactly gain by having more VRAM, Core Clock or Memory clock? Where can you apply those parameters.

Well first of all, you can't compare different GPU's with only those numbers, you should consult benchmarks for that..

 

Assuming we are talking about the same GPU:

VRAM: the higher the VRAM, the more texture data a GPU can store and use. More VRAM (3GB+) is especially helpful on resolutions higher than 1080p.

Core clock: how 'fast' the GPU is. Generally, higher is better on the same GPU.

Memory clock: A little bit of both other factors. Faster is better, it is for the VRAM, the faster it is the more data can be read.

Which card would be better for CF/SLI the one with more VRAM or the faster one, this is just an assumption, no specific card.

 

And thanks for the clarification

This again doesnt really work. It depends on Resolution and how much vRAM and the tier of the card. IE the r9 390 has 8gb of vRAM where as the 980ti has 6gb (2gb less) but the 980ti is much faster than the 390 and would be better in SLI compared to 390 CF. It doesnt work hear because realisitcally 6gb and 8gb are more than enough vRAM for pretty much everything besides 4k extreme texture packs / surround. And because the Cards themselves are in different tiers with the 390 being ~$330 and the 980ti being $650+

 

I would generalize as best I could to if your playing at 1440p or 1080p then if it has 3gb or more then pick based on speed. If it doesnt have 3gb then pick based on vRAM as you'll likely run into vRAM walls. But again this varies so greatly card to card you could find countless examples that go against this generalization

I know you said not card specific, buuuut...

 

You do want over 2GB of VRAM for Crossfire/SLI, because with 2GB it's IMO not worth it (it will bottleneck you). If on higher resolution, maybe even more than 4GB.

If you keep that one in mind, I guess the faster one after that.

Well I kinda had in mind the whole 970 and 390 dilemma that populates every second post up in here
