New leak sheds light on a 900W AD102 based graphics card from Nvidia; GeForce RTX 4080 and RTX 4070 VRAM and TGP also revealed

[Redaktion]

Renowned leaker Kopite7kimi has revealed that Nvidia is working on 900W TGP graphics card that has 48 GB of 24 Gbps VRAM and uses a AD102 GPU. Alternatively, the GeForce RTX 3080 and RTX 3070 will feature 16 GB/12 GB of VRAM  and draw 450W/300W of power, respectively.

Typo "GeForce RTX 3080 and RTX 3070 will" -> 4080 / 4070.

4080 with 450 or 400W?! Elsewhere, "like GA102" is interpreted as 350W (of a 3090 FE). Already this would be a shame since 3080 is 320W.

From 3070 with 220W to 4070 with 300W would be a tier higher, i.e., 4070 would replace 3080 on the TDP level. The question is: what is the speed of 4070 relative to 3080? The factors are 0.882x of the CUDA cores, shrinked nm possibly enabling the speed increment 1.6x, increased cache with unknown effect, 1.105x memory bandwidth, clock, possible new core structure etc. The known factors amount to 1.56x but the unknown factors let the final speed improvement be unknown.
