Sapphire Radeon RX 7900 XT 20GB GDDR6
The 20GB GDDR6 frame buffer on a 320-bit bus makes this card a strong value for high-resolution texture work and AI model prototyping where VRAM capacity is the primary bottleneck. Its triple-slot ATX form factor and 185W TDP deliver a rare combination of high memory capacity and moderate power draw for a modern GPU. This card is best for AI researchers and data scientists running large language models locally who need 20GB of VRAM without the cost or power requirements of a flagship workstation card.
