Notes on 8 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. 4NVIDIA GeForce RTX 5090, Recommended PSU: NVIDIA's minimum for a PC with a Ryzen 9 9950X; it recommends a PCIe CEM 5.1 compliant PSU.
  5. 5AMD Radeon RX 9070, Power connectors: Two 8-pin PCIe power connectors are required (2x 8-pin per AMD and Sapphire).
  6. 6AMD Radeon RX 9070, DisplayPort version: Club386 lists the DP 2.1a link rate as UHBR13.5; UHBR20 is not supported.
  7. 7NVIDIA GeForce RTX 5090, DisplayPort version: DisplayPort 2.1b at UHBR20 on all three DP outputs.
  8. 8NVIDIA GeForce RTX 5090, Slot width: The card is 2-slot, but NVIDIA's install guide asks for 3-slot (61 mm) case clearance.

Performance and Architecture

The NVIDIA GeForce RTX 5090 relies on the Blackwell architecture featuring 21,760 shader cores and delivering 104.8 TFLOPS of FP32 compute power. This massive core count enables heavy computational workloads and high frame rates.

By comparison, the AMD Radeon RX 9070 utilizes the RDNA 4 architecture with 3,584 cores and achieves 36.1 TFLOPS of FP32 compute. It counters with a peak boost clock of 2,520 MHz, making it a lighter alternative for standard gaming setups.

Memory and Display Outputs

Equipped with 32 GB of GDDR7 video memory across a 512-bit bus, the GeForce RTX 5090 yields a massive 1,792 GB/s of memory bandwidth and a 96 MB last-level cache. It also features three DisplayPort 2.1b ports running at UHBR20 alongside an HDMI 2.1b port.

The AMD Radeon RX 9070 features 16 GB of GDDR6 memory across a 256-bit bus, delivering 640 GB/s of bandwidth with a 64 MB cache. For displays, it includes a DisplayPort 2.1a link rate supporting UHBR13.5 and an HDMI 2.1b output.

Power and System Requirements

Power requirements differ drastically between these two graphics cards. The GeForce RTX 5090 demands a 575 W board power and requires a 1,000 W power supply using a 12V-2x6 connector.

Operating at a much lower 220 W board power, the Radeon RX 9070 needs only a 650 W power supply and utilizes two standard 8-bit PCIe power connectors. Partner overclocked cards can exceed 220 W, with IGN noting 249 W peaks.
