Deciding on the right amount of VRAM (video random access memory) for your next graphics card can be confusing. This guide breaks down what you need based on whether you're into gaming or running AI models locally.
For Gaming: The Sweet Spot
For 1080p and even up to 4K gaming, most people find 8GB of VRAM sufficient. Our pick for budget gamers is the GeForce RTX 5060, with its 145W TDP making it run on modest power supplies. However, when you start pushing into titles that require more VRAM or plan to overclock, the Arc B570 offers a 10GB GDDR6 buffer for only $219.
For those who want to future-proof their setup and are willing to spend more, the Radeon RX 7900 XTX is a solid choice. At an MSRP of $999, it gives you 24GB of VRAM at a fraction of the price of used RTX 4090s and the RTX 5090.
For Local AI: The Memory Requirements
When it comes to running AI models locally, the story changes. For smaller models like those with 7B-8B parameters, an 8GB card might suffice if you're not doing intensive inference work. But for anything above that-especially for larger models with 13B-20B parameters or even beyond-the GeForce RTX 5090 is the go-to choice. With its 32GB of VRAM and GDDR7, it comfortably handles the largest models available.
For more moderate needs-such as running 13B-14B models-the Radeon RX 7900 XTX is a competitive option. It offers 24GB of VRAM and excellent 4K raster performance, making it ideal for both gaming and local AI.
The GeForce RTX 4090 (used) is another option if you're looking to save some money. At $1599, it still beats everything except the 5090 in games and runs comfortably with models up to 32B-class.
Conclusion
Choosing the right amount of VRAM depends on your specific needs. For most gaming setups, an 8GB or even 10GB card will serve you well. If you're stepping into AI or require more headroom for future-proofing, go for cards with at least 24GB. With this guide, we hope to help you make a more informed decision.
