Notes on 7 values — test conditions and caveats
  1. 1AMD Radeon RX 9070 XT, Launch price: TechSpot reports AMD subsidizes this MSRP with a $50 retailer rebate, so street prices often run higher.
  2. 2AMD Radeon RX 9070 XT, Boost clock: TechSpot's 2400 MHz figure is AMD's 'game' clock; the boost rating is 2970 MHz.
  3. 3NVIDIA GeForce RTX 5080, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; it recommends a PCIe CEM 5.1 compliant PSU.
  4. 4AMD Radeon RX 9070 XT, Power connectors: Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.
  5. 5AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.
  6. 6NVIDIA GeForce RTX 5080, DisplayPort version: DisplayPort 2.1b at UHBR20 on all three DP outputs.
  7. 7NVIDIA GeForce RTX 5080, Slot width: The card is 2-slot (40 mm thick), but NVIDIA's install guide asks for 3-slot (61 mm) case clearance.

Performance and power

The NVIDIA GeForce RTX 5080 relies on the Blackwell architecture to deliver 56.3 TFLOPS of FP32 compute alongside faster memory bandwidth of 960 GB/s using GDDR7 type. It requires an 850 W power supply unit and draws 360 W of board power.

By contrast, the AMD Radeon RX 9070 XT features the Rdna 4 architecture with a higher boost clock of 2,970 MHz. It consumes less energy at 304 W board power and needs only a 750 W power supply unit.

Pricing and value

The AMD Radeon costs $599 at launch, making it much more affordable than the NVIDIA card. However, a $50 retailer rebate subsidizes this MSRP, which can affect real street availability.

The NVIDIA alternative demands a much higher investment at $999. Buyers pay this premium for advanced shader core counts reaching 10,752 cores.

Display outputs and connectivity

Both cards include one HDMI 2.1b port and three DisplayPort outputs. The NVIDIA option supports DisplayPort 2.1b at UHBR20 across all three outputs and manages up to 4 displays.

The AMD card utilizes DisplayPort 2.1a specifications with UHBR13.5 support. For power connection, the AMD model uses an 8-pin setup while the NVIDIA card requires a 12V-2x6 connector.
