Nvidia's new GPU generation, named after Ada Lovelace, is launched with three GeForce models. The RTX 4090 and the RTX 4080, with the 4080 being available in two very different variants. The new Founders Edition cooler design from Nvidia is shared by two of them and one is only available in the custom design of the partners.
RTX 4090 24 GB and RTX 4080 16GB with identical cooler
Even if Nvidia has mainly illustrated the flagship RTX 4090, there are indications that the RTX 4080 in the large version with 16 GB and more computing power as the so-called Founders Edition will also get the same cooler. Because Nvidia states a length of 30.4 cm, a width of 13.7 cm and a height and depth of 6.1 cm for both graphics cards. The cooler thus occupies three PCIe slots in the system.

It cannot be ruled out that the cooler is under the hood differs, even in the past supposedly identical coolers at Nvidia had not turned out to be completely identical – keyword vapor chamber instead of classic base plate.

For the RTX 4080 with 12 GB and the least computing power, Nvidia does not make any binding statements about the dimensions and instead writes that these “vary depending on the manufacturer”. This makes it clear that no Founders Edition is provided here. Instead, this version will only be available in the individual designs of the numerous graphics card manufacturers.

For both, Nvidia has provided the modern 12+4-pin socket (12VHPWR according to PCIe 5.0) for up to 450 watts – the plug theoretically allows up to 600 watts. Alternatively, three standard 8-pin connectors can be used with the supplied adapter. With the RTX 4080 12 GB, however, two 8-pin connectors are sufficient.

Like the predecessors, the RTX 4090 also offer three DisplayPort 1.4 and one HDMI 2.1. The new DisplayPort 2.0 is not yet available. This also applies to the PCIe connector, which stays with PCIe 4.0.
