RTX 4070 Super vs RX 7800 XT — used value, 12GB vs 16GB and software

RTX 4070 Super vs RX 7800 XT: used value, 12GB vs 16GB and software

Hardware advice reviewed 2026-10-20 · asking-price samples checked for freshness · Methodology

A previous-generation NVIDIA/AMD shortlist for used buyers, with 12GB on the GeForce and 16GB on the Radeon.

Verdict: Choose the RTX 4070 Super when CUDA support is required and 12GB is enough. Consider the RX 7800 XT for a supported workload that benefits from 16GB. Use current listings to judge value; this comparison does not assume AMD is always cheaper.

Verify model fit before buying

Memory capacity alone cannot tell you which models run. Check the artifact, runtime, context and concurrency, including cache and working buffers. Mac memory is shared with the operating system. See our memory sizing guide.

We have not benchmarked these configurations. Hardware advice reviewed 2026-10-20. Check the sources below for supported hardware and software requirements.

Buying for games and occasional AI

Write down which workload matters most. For games, compare the titles and settings you actually use. For AI, a 12GB limit or an unsupported extension can settle the decision even if a gaming comparison favors the other card.

How to compare gaming results

Use results for the same game, resolution, settings and test system. Separate native rendering from upscaling and frame generation, and look at frame-time consistency as well as average FPS. We have not run matched gaming benchmarks for these cards.

FAQ

Is the RX 7800 XT supported in Ollama?

Ollama lists the RX 7800 XT in its Linux and Windows ROCm tables. Follow the requirements for your installed version; that listing does not certify unrelated training or image-generation software.

Which price should I use for this comparison?

Use the dated eBay sample medians as a starting point, then compare shipping, tax, condition and returns. A missing sample means insufficient fresh data, not that the card is unavailable. Historical editorial estimates are not checkout offers.
