RX 9070 XT vs RTX 5080

NVIDIA lists 10,752 CUDA cores on the RTX 5080, a 2.62 GHz boost clock, a 2.30 GHz base clock, 16 GB of GDDR7, and a 256-bit memory interface. NVIDIA marks ray tracing as supported, and names DLSS 4 with Super Resolution, DLAA, Ray Reconstruction, Frame Generation, and Multi Frame Generation. The memory amount is the same 16 GB. GDDR6 and GDDR7 are not the same memory type.

Power and the power supply

AMD rates the RX 9070 XT at 304 W typical board power, recommends a 750 W minimum power supply, and lists a 2x 8-pin power connector. NVIDIA rates the RTX 5080 at 360 W total graphics power and lists 850 W required system power. NVIDIA says that minimum is based on a PC configured with a Ryzen 9 9950X processor, and that power requirements can differ by system. NVIDIA says a higher power rating may be required depending on the system. Supplementary power on the RTX 5080 is three PCIe 8-pin cables, with an adapter in the box, or one 450 W or greater PCIe Gen 5 cable. NVIDIA says graphics card specifications may vary by add-in-card manufacturer.

Ray tracing and upscaling

NVIDIA lists ray tracing on the RTX 5080, plus DLSS 4 with Super Resolution, DLAA, Ray Reconstruction, Frame Generation, and Multi Frame Generation. That feature set is the reason to pay the higher starting price. It is not a frame-rate result.

AMD calls the machine-learning upscaler FSR Upscaling, formerly FidelityFX Super Resolution 4. AMD says FSR 4 was renamed so it sits apart from the other features in FSR "Redstone": FSR Upscaling, FSR Frame Generation, FSR Ray Regeneration, and FSR Radiance Caching. AMD says ML upscaling is available on Radeon RX 7000 Series and RX 9000 Series graphics cards, with RX 6000 Series support launching in 2027. The RX 9070 XT is an RX 9000 Series card, so it is in that set. Some games have native integration, and the in-game menu may still say FSR 4. Other games that already have FSR 3.1 or higher can be upgraded in AMD Software, which swaps DLLs. AMD publishes the supported games. AMD's supported-games note says Redstone support on RX 9000 Series cards uses AMD Software Adrenalin Edition 25.12.1 or newer.

RTX 5070 vs RX 9070 vs RX 9070 XT

NVIDIA lists the GeForce RTX 5070 with 12 GB of GDDR7 on a 192-bit interface, 250 W total graphics power, 650 W required system power, and a starting price of $549. NVIDIA lists the same DLSS 4 feature names on the RTX 5070 as on the RTX 5080. AMD's press release lists the Radeon RX 9070 at 56 compute units, 16 GB of GDDR6, a 256-bit interface, 64 MB of Infinity Cache, 220 W typical board power, and a $549 suggested price, with a boost clock of up to 2.5 GHz. AMD's RX 9070 product specs list a boost frequency of up to 2520 MHz, a game frequency of 2070 MHz, a 2x 8-pin connector, and a 650 W minimum power supply.

The RTX 5070 has 12 GB. The RX 9070 and the RX 9070 XT each have 16 GB. If later games are the worry, that memory amount is the difference, not a promise about how long either card stays useful. The RX 9070 XT adds 64 compute units and 304 W against 56 compute units and 220 W on the RX 9070, at a $599 suggested price against $549.

Who should buy which

Choose the RX 9070 XT when 16 GB and the $599 suggested price matter more than NVIDIA's DLSS 4 features. Choose the RTX 5080 when you want those features, including Multi Frame Generation and Ray Reconstruction, and the gap from $999 is acceptable. Choose the RTX 5070 over the RX 9070 XT only when you want DLSS 4 and ray tracing and you can accept 12 GB instead of 16 GB. Nvidia vs AMD covers the broader brand choice. Check current prices before you buy, and size the power supply from the recommendation for the card you pick.
