Notes on 6 values — test conditions and caveats
- 1AMD Radeon RX 9070 XT, Launch price: TechSpot reports AMD subsidizes this MSRP with a $50 retailer rebate, so street prices often run higher.
- 2AMD Radeon RX 9070 XT, Boost clock: TechSpot's 2400 MHz figure is AMD's 'game' clock; the boost rating is 2970 MHz.
- 3NVIDIA GeForce RTX 4080 Super, Recommended PSU: NVIDIA's 750 W minimum assumes a PC with a Ryzen 9 5900X; needs vary by configuration.
- 4AMD Radeon RX 9070 XT, Power connectors: Corsair notes a few partner 90-series cards use 12V-2x6; the vast majority use 2x 8-pin.
- 5NVIDIA 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.
- 6AMD Radeon RX 9070 XT, DisplayPort version: TechPowerUp specifies the DisplayPort outputs as UHBR13.5.
Performance and Architecture
The GeForce RTX 4080 Super utilizes the Ada Lovelace architecture with 10,240 shader cores and delivers 52 TFLOPS of FP32 compute performance. This setup provides strong processing power for heavy workloads.
In contrast, the Radeon RX 9070 XT runs on Rdna 4 with 4,096 cores and reaches a 2,970 MHz boost clock, coming out ahead in clock speed and consuming less power at 304 W compared to the competitor's 320 W.
Memory and Interface
While both cards pack 16 GB of video memory, the GeForce RTX 4080 Super uses Gddr6x memory achieving a 736 GB/s bandwidth and 23 Gbps speed. The Radeon RX 9070 XT relies on standard Gddr6 memory operating at 640 GB/s and 20 Gbps.
For motherboard connectivity, the Radeon RX 9070 XT takes the lead with PCIe 5.0 support, whereas the competitor stays on PCIe 4.0.
Display and Video Features
The Radeon RX 9070 XT includes HDMI 2.1b and DisplayPort 2.1a outputs, offering updated connection standards for modern displays. It also expands hardware encode support to include H.264, HEVC, and AV1 formats.
Meanwhile, the GeForce RTX 4080 Super features two video encoders and supports AV1 hardware encoding, handling up to four displays simultaneously.
The Verdict
Buy the AMD Radeon RX 9070 XT if you want modern PCIe 5.0 support, faster boost clocks, and advanced display outputs at a lower launch price. Buy the NVIDIA GeForce RTX 4080 Super if you need higher shader core counts, Gddr6x memory bandwidth, and dual encoders.
