NVIDIA's GeForce RTX 4090 is the first consumer graphics card in their GeForce RTX 40-series, which is based on the Ada Lovelace architecture, and includes a host of improvements to both the number and speed of its various cores. In terms of performance, this GPU is up to twice as fast as the previous-gen RTX 3090 - but that comes at the cost of higher power draw, similar to the RTX 3090 Ti. It shares the same 24GB of memory that those cards offered as well, along with a pair of upgraded video encoders with added support for the AV1 codec.

Most versions of the RTX 4090 use a multi-fan cooling layout. That is great for keeping a single card running cool and relatively quiet, but results in most of the heat the card generates being pumped back into the computer. They are also a lot larger than traditional video cards, making these less than ideal for multi-GPU systems. In most chassis only one will be able to fit and be cooled properly, but some larger tower cases may be able to handle two of them. Small form factor and even mini tower cases may not be able to fit it at all.

Finally, in regards to connectivity, there are one HDMI 2.1a and three DisplayPort 1.4a plugs supporting a total of up to four displays at a maximum resolution of 7680x4320 (8K).
