NVIDIA’s RTX 4090 will reportedly come in two TGP variants, one topping out at 450W and the other at 600W. Based on the AD102 die, the top-end Lovelace GPU will feature 16,384 FP32 cores alongside 24GB of GDDR6X memory via a 384-bit bus. The 11 GPCs will be paired with up to 96MB of L2 cache with 128 RT Cores (at least) and 512 Tensor Cores. Interestingly, a rumor from Chiphell states that the RTX 4090 will be offered in two different variants: 450W and 600W.

This is unheard of, and we’ve never had a GeForce SKU with such a wide TGP range. Logic dictates that the Founders’ Edition will feature the 450W TGP and overengineered AIB models hitting 600W or more. However, there’s a good chance that NVIDIA might limit the board partner models to 450W and the FE cards to 600W. Or of course, we could get both in both flavors.
The RTX 4090 will allegedly be the only next-gen GPU to release this year with the RTX 4080 and 4070 getting pushed to 2023. Furthermore, the flagship Lovelace graphics card will cost less than the RTX 3090 Ti, meaning likely between $1,500 and $2,000. There’s also the RTX 4090 Ti which will feature the (nearly) fully enabled AD102 core. It’ll be an absolute monster with a whopping 48GB of 24Gbps GDDR6X memory. You can read more about it here.
