Notes on 5 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. 3AMD Radeon RX 9070 XT, Power connectors: Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.
  4. 4NVIDIA GeForce RTX 4070 Super, Power connectors: Nvidia's 16-pin header is the 12V-2x6 variant; an adapter cable for non-ATX 3.0 power supplies ships with the card.
  5. 5AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.

Performance and Compute

The AMD Radeon RX 9070 XT surges ahead in raw computation with 48.7 TFLOPS and a 2,970 MHz boost clock, while the NVIDIA GeForce RTX 4070 Super counters with 7,168 shader cores. In practice, higher compute figures help chew through heavy rendering tasks and demanding frame rates without stuttering.

Memory configuration further splits the pair. The Radeon offers 16 GB of video memory on a 256-bit bus yielding 640 GB/s bandwidth, beating the NVIDIA's 12 GB GDDR6X on a 192-bit bus. This extra headroom prevents texture bottlenecks at high resolutions.

Power and System Needs

The NVIDIA card demands far less electricity, drawing 220 W under load compared to the AMD's 304 W board power. This lower consumption lets you run the system on a modest 600 W power supply instead of the 750 W recommended for the Radeon.

Power connections also differ. The NVIDIA relies on a 12V-2x6 header that ships with an adapter, while the AMD variant generally uses dual 8-pin connectors, though partner models vary.

Connectivity and Video

The Radeon supports PCIe 5.0 for faster data transfer rates with modern motherboards, leaving the NVIDIA stuck on PCIe 4.0. Both cards provide identical port layouts with three DisplayPort outputs and one HDMI port.

For displays and video engines, the AMD features HDMI 2.1b and DisplayPort 2.1a outputs. The NVIDIA supports up to four displays simultaneously and encodes AV1 video, whereas the AMD expands encoding to include H.264 and HEVC.

FAQ

What power supply do I need for these graphics cards?

You need a 750 W power supply for the Radeon RX 9070 XT, while the RTX 4070 Super requires only a 600 W unit.

Which card has better video memory specifications?

The Radeon RX 9070 XT wins with 16 GB of GDDR6 memory on a 256-bit bus, compared to the 12 GB GDDR6X on a 192-bit bus found on the RTX 4070 Super.

Do both cards support AV1 video encoding?

Yes, both cards support AV1 hardware encoding, but the Radeon also adds H.264 and HEVC encoding capabilities.

What are the PCIe version differences between them?

The Radeon RX 9070 XT supports PCIe 5.0 for faster host communication, whereas the RTX 4070 Super uses PCIe 4.0.
