Notes on 6 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. 4AMD Radeon RX 7800 XT, HDMI version: AMD's spec page lists HDMI 2.1; its own press release and Notebookcheck state HDMI 2.1a.
  5. 5AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.
  6. 6AMD Radeon RX 7800 XT, DisplayPort version: Notebookcheck lists the DisplayPort 2.1 link rate as UHBR13.5; AMD notes DP 2.1 support depends on AIB designs.

Performance and Architecture

The newer Rdna 4 architecture on the 9070 XT drives higher shader counts and compute power to handle demanding games with greater ease. It reaches 4,096 shader cores and 48.7 TFLOPS of FP32 compute, outperforming the 7800 XT and its 3,840 cores.

Boost clocks also favor the newer card significantly, pushing up to 2,970 MHz [TechSpot's 2400 MHz figure is AMD's 'game' clock; the boost rating is 2970 MHz.] compared to 2,430 MHz on the 7800 XT. Gamers looking for maximum frame rates will find the raw processing advantages yield smoother gameplay in heavy titles.

Memory and Interface Speed

While both cards share 16 GB of GDDR6 video memory and a 64 MB last-level cache, the 9070 XT achieves faster memory speeds at 20 Gbps and a higher memory bandwidth of 640 GB/s.

Connection standards are also more modern on the 9070 XT, utilizing PCIe 5.0 for data transfer compared to PCIe 4.0 on the 7800 XT. This ensures better compatibility with next-generation motherboards and faster communication with the rest of the system.

Power and System Requirements

Higher performance demands more electrical current, meaning the 9070 XT requires a more robust power supply and draws more power under load. It carries a board power of 304 W and requires a 750 W recommended PSU, using 8-pin connectors [Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.].

In contrast, the 7800 XT is lighter on the electrical grid with a board power of 263 W and a 700 W recommended PSU. Buyers must ensure their current power setup can handle the heavier energy demands before upgrading.

Display Outputs and Pricing

Display connectivity is slightly more advanced on the newer flagship, featuring HDMI 2.1b and DisplayPort 2.1a [TechPowerUp specifies the DisplayPort outputs as UHBR13.5.] with three ports. The 7800 XT relies on HDMI 2.1a [AMD's spec page lists HDMI 2.1; its own press release and Notebookcheck state HDMI 2.1a.] and DisplayPort 2.1 [Notebookcheck lists the DisplayPort 2.1 link rate as UHBR13.5; AMD notes DP 2.1 support depends on AIB designs.], while also supporting up to 4 displays.

At launch, the 7800 XT costs $499, making it cheaper than the 599 USD [TechSpot reports AMD subsidizes this MSRP with a $50 retailer rebate, so street prices often run higher.] launch price of the 9070 XT.
