If you want to make most of your latest gaming PC build or quick GPU upgrade, it’s worth considering how much VRAM is included in the graphics card you choose. So, for the most capable GPUs, we suggest taking a look at the amount of VRAM (memory) on offer. We’ve picked out all the best cards featuring the most VRAM out there right now.

Which GPU to get for most VRAM

Nvidia’s GeForce RTX 3090 Ti features 24GB VRAM and a base clock speed of 1.67GHz. It can also be overclocked up to 1.86GHz using 2nd-generation Ray Tracing Tech and 3rd-generation Tensor Cores. DirectX 12 Ultimate, Nvidia DLSS, and G-Sync VRR are all supported by the card. You can connect two RTX 3090 Ti cards to the Nvidia NVLink for performance and speed that are truly extraordinary.

Ampere-NVIDIA’s 2nd generation RTX architecture powers the GeForce RTX 3090 Ti and 3090. These devices feature 2nd generation RT Cores (and 3rd generation Tensor Cores), streaming multiprocessors, and 24 GB of G6X RAM to provide high-quality performance for creators and gamers.

The 3090 will likely become obsolete as computers advance and move to higher resolutions, such as 8K. Most games that can be run at 8K with the 3090 are already too complex to handle. Many will run at playable framerates using DLSS (which is not 8K). As resolution continues to rise and games use better hardware to create better graphics, there will always come the point when you require a better GPU.

It may seem like the 3090s VRAM is overkill for gaming, but that is always true of top-tier graphics cards when they debut, making them greatly future-proof.

New GPUs with the most VRAM

Although the 3090 and 3090 Ti broke new ground when they released, the newest generation of cards are here to show off their impressive levels of VRAM too. It seems as if 24GB is the limit (for now), but with advancements in other areas helping boost their power even higher.

Take a look at the RTX 4090 and RX 7900 XTX – both featuring 24GB of VRAM. The RX 7900 XT falls just below the mark with 20GB.
