AMD may have announced the Radeon RX 7900 series a few weeks ago, but it has taken the company until now to reveal how its latest offerings compare against the RTX 4080, NVIDIA's latest Ada Lovelace architecture card. Unsurprisingly, the Radeon RX 7900 XTX offers better value for money than the RTX 4080 while also usurping the performance of the Radeon RX 6950 XT.

The GeForce RTX 4080 has now arrived, albeit only the 16 GB model following NVIDIA's abrupt 'unlaunch' of the 12 GB model, which the company is rumoured to have repackaged as the RTX 4070 Ti. There is still almost a month's wait before AMD starts selling the Radeon RX 7900 XT and the Radeon RX 7900 XTX too. At launch, AMD decided against revealing too many performance details, with the company confirming essential specifications, pricing and a release date instead.

AMD has now published some gaming benchmarks, as well as several performance metrics just as the RTX 4080 becomes orderable. To recap, the RTX 4080 offers 16 GB of GDDR6X VRAM with a 256-bit bus and 717 GB/s memory bandwidth. By contrast, the Radeon RX 7900 XT has 20 GB of slower GDDR6 VRAM but with an 800 GB/s bandwidth because of its wider 320-bit bus. The Radeon RX 7900 XTX goes even further too, with 24 GB of GDDR6 VRAM on a 384-bit bus to deliver a bandwidth of 960 GB/s.

As the screenshots below show, AMD is marketing both RX 7900 cards as outperforming the Radeon RX 6950 XT when gaming in 4K at maximum settings. Supposedly, the pair manage this feat with FSR off or on, although AMD has left fans in the take about how the RX 7900 XT or RX 7900 XTX stack up against the RTX 4080 in this regard. Instead, the company has sought to highlight that both cards offer higher TFLOPs than the RTX 4080 but at a lower price. Specifically, while the RTX 4080 peaks at a mere 49 TFLOPs, the Radeon RX 7900 XT and Radeon RX 7900 XTX offer 52 TFLOPs and 61 TFLOPS, respectively.

The Radeon RX 7900 series will be available from December 13. At launch, the Radeon RX 7900 XT should retail for US$899, with the Radeon RX 7900 XTX priced US$100 higher. In comparison, the RTX 4080 will arrive sooner, but for US$1,199. Overall, AMD is positioning the Radeon RX 7900 series as providing better value for money than the RTX 4080, with added bonuses like DisplayPort 2.1 compatibility and a USB Type-C port. Presumably, AMD will reveal gaming benchmarks within the next few weeks following the RTX 4080's release.
