Notes on 6 values — test conditions and caveats
  1. 1AMD Radeon RX 9070, Launch price: AMD's $549 starting MSRP at launch; AMD sells no reference card, so partner models may cost more.
  2. 2AMD Radeon RX 9070, Boost clock: Peak 'up to' boost; AMD's game clock is 2070 MHz for typical gaming.
  3. 3AMD Radeon RX 9070, Board power: Partner overclocked cards can exceed 220 W; IGN measured 249 W peaks on a factory-OC card.
  4. 4AMD Radeon RX 9070, Power connectors: Two 8-pin PCIe power connectors are required (2x 8-pin per AMD and Sapphire).
  5. 5NVIDIA 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.
  6. 6AMD Radeon RX 9070, DisplayPort version: Club386 lists the DP 2.1a link rate as UHBR13.5; UHBR20 is not supported.

Memory and Performance

The Radeon comes out ahead with 16 GB of video memory and a 256-bit bus width, outstripping the competitor's 12 GB and 192-bit setup. This wider path and larger pool help handle high-resolution textures without stuttering in modern games.

While the GeForce relies on GDDR6X memory running at 21 Gbps for high speed, the AMD card counters with a larger 64 MB last-level cache to keep data moving efficiently.

Power and Connections

Both options draw 220 W of board power, but they require different power cables. The NVIDIA option uses a 12V-2x6 header that needs an adapter for older power supplies, whereas the AMD card uses standard 8-pin connectors.

For motherboard and display connectivity, the AMD alternative supports PCIe 5.0 alongside HDMI 2.1b and DisplayPort 2.1a ports. The competitor stays behind on PCIe 4.0 and older display standards.
