Get RTX 5070 if your supported games or required applications favor NVIDIA features. Get RX 9070 if you need 16GB and have confirmed Radeon support; compare the exact board and current listing before buying.
Dimensions, connectors and PSU guidance vary by board

How we chose
Research-based, not lab-tested. This comparison uses NVIDIA and AMD reference specifications, not our own frame-rate measurements. It compares RTX 5070 with RX 9070: neither RTX 5070 Ti nor RX 9070 XT is a substitute. There is no universal performance winner asserted here.
Capacity is a constraint, not a benchmark
The NVIDIA specification lists 12GB for RTX 5070; AMD’s launch specification lists 16GB for RX 9070. Extra capacity can be a useful selection criterion when a workload requires it. It does not establish higher frame rates, better ray tracing or faster creation work by itself.
Before ordering, identify the games, texture settings and applications that matter. Consult current evaluations using those exact workloads. A benchmark at another resolution or with different image reconstruction settings is not a direct answer for your PC.
Compare the same rendering mode
Separate native rendering, upscaling and frame generation. Generated frames can change displayed output, but a frame-generation figure is not interchangeable with native rendered performance or responsiveness. Supported features also vary by game and version.
If your decision rests on DLSS, ray reconstruction or an application-specific NVIDIA feature, verify its availability in that software. If it rests on FSR, do the same for the Radeon path. Neither brand’s feature name proves support across your library. Avoid comparing one card’s generated-frame number with the other’s native number.
Fit the exact board to the system
The reference figures shown above describe different vendors’ power specifications; they are not wall-power measurements. Partner-board limits, coolers and connectors can differ. Read the exact board manufacturer’s dimensions, power-connector requirements and PSU guidance. Include connector clearance in a compact case.
Do not choose a power supply from GPU wattage alone. Account for the rest of the system and use compatible cables according to the PSU and card instructions. A GPU swap should not depend on an unverified adapter or a guessed connector fit.
How to use the Amazon links
The buttons open searches for the named GPU because partner-board listings vary. They are not confirmed exact-SKU offers. Match the chip name, memory, cooler, seller and condition; reject Ti/XT substitutions if you intend this comparison. Check the current total and return terms. No current Amazon price or availability is represented on this page.
No. This guide uses the non-XT chip. Recheck every listing and benchmark label before making a purchase comparison.
Does 16GB automatically make RX 9070 the better buy?
No. Capacity, workload support, relevant measured performance and the exact board’s total all matter. If you do not know which requirement your current GPU fails, keep it until you can identify that gap.
Should I use a chip specification to choose the power cable for a partner board?
No. Use the exact board and PSU manufacturers’ instructions. Chip-level reference power does not identify every partner board’s connector, clearance or cable requirements.
Choose by workload
1440p gaming: compare current evaluations of your games at the same resolution, settings and rendering mode. No universal frame-rate winner is asserted here.
Creation: check the application’s supported GPU features and memory requirements before choosing a brand.
Power and fit: use the exact board manufacturer’s connector, case-clearance and PSU guidance. The two vendors’ reference-power definitions are not an equivalent wall-power measurement.
