Notes on 9 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 7700 XT, Base clock: AMD publishes only Game (2171 MHz) and Boost clocks; no base clock appears on AMD's page.
  4. 4AMD Radeon RX 7700 XT, Memory bandwidth: AMD also lists 1995 GB/s 'effective' bandwidth including Infinity Cache; 432 GB/s is the raw VRAM figure.
  5. 5AMD Radeon RX 7700 XT, Recommended PSU: AMD bases this rating on a Ryzen 9 7950X system; your needs may differ.
  6. 6AMD Radeon RX 9070 XT, Power connectors: Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.
  7. 7AMD Radeon RX 7700 XT, Power connectors: Reference card uses two 8-pin PCIe power connectors.
  8. 8AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.
  9. 9AMD Radeon RX 7700 XT, DisplayPort version: Notebookcheck specifies the DP 2.1 output at UHBR13.5 link rate.

Performance and Compute

The newer Rdna 4 architecture delivers substantial gains over Rdna 3. The 9070 XT reaches 48.7 TFLOPS of FP32 compute alongside 4,096 shader cores and a 2,970 MHz boost clock, outclassing the 7700 XT at 35.2 TFLOPS.

This raw capability translates into smoother frame rates and faster rendering in heavy workloads. Buyers prioritizing maximum graphics horsepower will find the newer architecture a significant upgrade.

Memory and Interface

Equipped with 16 GB of Gddr6 memory on a 256-bit bus, the 9070 XT moves data much faster than its rival. It also introduces PCIe 5.0 support for higher bandwidth across the motherboard slot.

The 7700 XT relies on 12 GB of Gddr6 across a 192-bit bus and PCIe 4.0. Opting for the 9070 XT secures longer-term headroom for high-resolution textures and modern display standards like DisplayPort 2.1a.

Power and System Requirements

Higher performance demands more energy. The 9070 XT draws 304 W and requires a 750 W power supply unit, utilizing standard 8-pin connectors.

In contrast, the 7700 XT pulls 245 W and asks for a 700 W recommended PSU. Buyers must ensure their current power supply and cooling setups can handle the increased thermal output of the faster card.
