RTX 4070 Ti Super vs RX 7900 XT — 16GB CUDA or 20GB Radeon?

RTX 4070 Ti Super vs RX 7900 XT: 16GB CUDA or 20GB Radeon?

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

A higher-memory used-card shortlist: the RTX 4070 Ti Super provides 16GB and the RX 7900 XT provides 20GB.

Verdict: The RX 7900 XT has 4GB more VRAM. Choose it when a supported workload needs that headroom and the total price makes sense. Choose the RTX 4070 Ti Super for required NVIDIA software; 20GB does not compensate for an application that cannot use the card.

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.

Where 20GB can help

A workload just above the 16GB limit may fit on the Radeon, depending on backend overhead. Include context cache and concurrent requests in the estimate. If the workload exceeds 20GB too, neither is the right capacity target.

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 RTX 4070 Ti the same card as the Ti Super?

No. This page compares the RTX 4070 Ti Super with 16GB. Do not use a listing for the non-Super card as a price substitute; verify the complete name and memory configuration.

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.
