Latest specifications

GeForce RTX 4090
– GPU: AD102-300, TSMC 4nm, boost clock: 2520 MHz
– CUDA cores: 16384 (128 SMs, 128 cores/SM)
– ROPs: 384
– memory: 24GB GDDR6X, 384-bit
– Power consumption: default TGP: 450W, max TGP: 660W
– Power connector: single 16-pin

The TGP is the Total Graphics Power, the power consumption of the whole graphics card.

In a world with cheap electricity prices, this card could have a sense, but today…
