Which should you buy?
Both GPUs have 16GB of VRAM on a 256-bit bus (GDDR7 on the RTX 5080, GDDR6X on the RTX 4080 SUPER), so they hold similar model sizes; compare price, condition and rated power. In this catalog, the RTX 5080 has the lower median recorded price ($1,864.00 against $1,899.00). The lowest recorded price per GB of VRAM is $87.50 for the RTX 4080 SUPER. Memory capacity does not measure speed, and these are recorded Amazon US quotes rather than live checkout prices, so confirm the current offer, condition, exact board and your power supply before buying.
Use the LLM VRAM estimator to check how much memory your model needs, then compare listings on the RTX 5080 page and the RTX 4080 SUPER page.
