NVIDIA RTX 4080 + 4090 Founders Edition Cards

Recently we finally received the GeForce RTX 4080 and RTX 4090 graphics cards for Linux testing from NVIDIA. For those that have been eager to see how the RTX 40 series hardware performs under Linux, here are my initial Linux gaming benchmarks featuring a variety of Linux native titles as well as with Steam Play for running Windows games on Linux atop Proton + DXVK/VKD3D-Proton. The GeForce RTX 4080/4090 Linux performance is compared against a variety of other graphics cards including the new Radeon RX 7900 XTX with its open-source upstream Linux driver support.

The GeForce RTX 4080 requires a 450W or greater PCIe Gen 5 cable otherwise with the included adapter can be powered off three PCIe 8-pin cables when using a 750 Watt or greater power supply.


Meanwhile the GeForce RTX 4090 is the current top-end Ada Lovelace consumer graphics card. The GeForce RTX 4090 pricing starts out at $1,599 USD for this graphics card that features 16,384 CUDA cores, a 2.23GHz base clock with 2.52GHz boost clock, and 24GB of GDDR6X video memory.


The GeForce RTX 4090 is an absolute beast but does have a Total Graphics Power rating of 450 Watts and requires using 4x PCIe 8-pin power cables with the included adapter otherwise a 450 Watt or greater PCIe Gen 5 power cable. NVIDIA recommends a system power supply of at least 850 Watts for running the power hungry but immensely powerful GeForce RTX 4090.
