AMD specifies 20 GiB of GDDR6 memory for the RDNA 3 Radeon RX 7900 XT; the entry describes memory capacity, not software compatibility.
LLMGauge uses dedicated VRAM as the conservative GPU-capacity signal. Integrated/shared-memory graphics are not treated as dedicated GPU capacity by the current engine, so those systems may be classified as CPU-only even when the operating system can share RAM with graphics.
