GeForce RTX 4080 and 4070 less power hungry than expected?

After the upward revision of the technical specifications of the GeForce RTX 4070, the rumors offer us unexpected good news regarding the energy demands of two of the next flagships of NVIDIA. According to leaker Kopite7kimi, the TGP of the GeForce RTX 4080 and the RTX 4070 would be lower than expected: the figure of the 4080 drops by 100W, going from 420 to 320Wwhile that of the 4070 goes from 320 to 285W.

TGP, or Total Graphics Power, is a term used by NVIDIA to refer to the power a power supply should deliver to the graphics subsystem during a stressful load. AMD uses the term TBP (Total Board Power) instead. The GeForce RTX 4090, according to rumors, should instead be around 450W, similar to the current RTX 3090 Ti.

The value indicated for the RTX 4080 is identical to that of the RTX 3080 10GB, while in the case of the RTX 4070 we observe an increase of 65W from the 220W of the RTX 3070. The RTX 4070, according to previous rumors, should offer similar performance to the RTX 3090 Ti, therefore we should see a big leap forward in terms of the “performance per watt” ratio. The leaker himself states that the RTX 4070 will be accompanied by a base clock of 2310 MHz and a boost clock of 2610 MHzwith the ability to go beyond 2800 MHz in optimal operating conditions – values ​​much higher than the Ampere era.

The rumors report also of the existence, at least in the NVIDIA laboratories, of a possible GeForce RTX 4080 Ti, a card with a GPU equipped with 14848 active CUDA cores and 20GB of GDDR6X memory at 21 Gbps on a 320-bit bus. However, it cannot be excluded that it is a video card for the world of workstations (and whose specifications could be resumed, next year, for an update of the offer).
