Notes on 7 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 4080 Super, Recommended PSU: NVIDIA's 750 W minimum assumes a PC with a Ryzen 9 5900X; needs vary by configuration.
  5. 5AMD Radeon RX 9070, Power connectors: Two 8-pin PCIe power connectors are required (2x 8-pin per AMD and Sapphire).
  6. 6NVIDIA GeForce RTX 4080 Super, Power connectors: Card takes a 16-pin 12V-2x6 connector; a 3x PCIe 8-pin adapter ships in the box for PSUs without a PCIe Gen 5 cable.
  7. 7AMD Radeon RX 9070, DisplayPort version: Club386 lists the DP 2.1a link rate as UHBR13.5; UHBR20 is not supported.

Performance and Architecture

The NVIDIA GeForce RTX 4080 Super utilizes the Ada Lovelace architecture to deliver significantly more shader cores and a higher FP32 compute capability of 52 TFLOPS compared to the AMD Radeon RX 9070. This raw computing advantage translates into faster processing for heavy workloads and demanding graphics.

In contrast, the AMD Radeon RX 9070 relies on the RDNA 4 architecture, offering 3,584 cores and 36.1 TFLOPS of FP32 compute. While it trails in raw shader count, it delivers a peak boost clock of 2,520 MHz [Peak 'up to' boost; AMD's game clock is 2070 MHz for typical gaming.] that keeps it competitive in everyday gaming scenarios.

Memory and Bandwidth

Both cards feature 16 GB of video memory on a 256-bit bus, making them well-equipped for modern high-resolution textures. They also share a 64 MB last-level cache.

The NVIDIA GeForce RTX 4080 Super pulls ahead by using GDDR6X memory type, achieving a memory speed of 23 Gbps and a bandwidth of 736 GB/s. The AMD Radeon RX 9070 uses standard GDDR6 memory, resulting in a lower memory speed of 20 Gbps and a bandwidth of 640 GB/s.

Power and Efficiency

Power consumption heavily favors the AMD Radeon RX 9070, which has a board power of just 220 W ★ [Partner overclocked cards can exceed 220 W; IGN measured 249 W peaks on a factory-OC card.]. It requires an accessible power setup with an 8-pin [Two 8-pin PCIe power connectors are required (2x 8-pin per AMD and Sapphire).] connector and a 650 W ★ recommended PSU.

Meanwhile, the NVIDIA GeForce RTX 4080 Super demands a much higher board power of 320 W and a 750 W [NVIDIA's 750 W minimum assumes a PC with a Ryzen 9 5900X; needs vary by configuration.] minimum PSU. It also requires a modern 12V-2x6 power connector, though a 3x PCIe 8-pin adapter ships in the box for older power supplies.
