Frequently Asked Questions

Why is 20GB VRAM uncommon compared to 16GB or 24GB?

It depends on each manufacturer's specific memory bus and chip design for a given model — 20GB tends to appear on select high-end cards rather than being a standard tier.

Is 20GB worth it over 16GB for gaming alone?

For gaming specifically, the difference is usually marginal — but if the card underneath also offers a genuine performance step up, it can be a strong overall pick regardless of the VRAM gap.

Is 20GB enough for local AI/LLM work?

It handles many mid-sized models comfortably, though the largest local LLMs may still want 24GB+ — check our Workstation GPU rankings if AI/ML work is your primary use case.
