Recently, there has been more and more news about the GeForce RTX 40 series. From September 19th to 22nd, 2022, NVIDIA will hold the "NVIDIA GTC Conference", and it is very likely that the new generation of GPUs with Ada Lovelace architecture will be officially announced.


According to the information leaked in the past, NVIDIA's next-generation GPU based on the Ada Lovelace architecture will have five models, namely AD102, AD103, AD104, AD106 and AD107, of which AD106 and AD107 are for mainstream and entry-level markets.

At present, some media have confirmed some of the upcoming desktop NVIDIA cards.


GeForce RTX 4090 will use AD102-300 GPU, with 128 SMs, that is, 16384 CUDA cores, the acceleration frequency will reach 2520MHz, equipped with 24GB GDDR6X video memory, the video memory bit width is 384 bits, and the video memory rate is 21Gbps, which means the video memory bandwidth will exceed 1TB/s. Its default TGP is 450W, and the maximum TGP that can be set by BIOS is 660W.


GeForce RTX 4080 16GB uses AD103-300 GPU, has 76 SMs, that is, 9728 CUDA cores, the acceleration frequency will reach 2505MHz, is equipped with 16GB GDDR6X video memory, the video memory bit width is 256 bits, and the video memory rate is 23Gbps. It is rumored that GeForce RTX In the 40 series, only this graphics card uses this speed of memory. Its default TGP is 340W, and the maximum TGP that can be set by the BIOS is 516W.

GeForce RTX 4080 12GB adopts AD104-400 GPU, has 60 SMs, that is, 7680 CUDA cores, the acceleration frequency will reach 2610MHz, and is equipped with 12GB of GDDR6X video memory, the video memory bit width is 192 bits, and the video memory rate is 21Gbps. Its default TGP is 285W, and the maximum TGP that can be set by the BIOS is 366W.

The GeForce RTX 4090 is expected to be released in early October, and the 12GB and 16GB versions of the GeForce RTX 4080 should wait until early November, although pricing for these cards is unclear for now.


Although it is not far from NVIDIA's launch of the next-generation Ada Lovelace architecture GPU, the GeForce RTX 30 series will continue to be sold in the mainstream and entry-level markets for some time to come.

Previously, it was reported that Nvidia will continue to release several GeForce RTX 30 series graphics cards, namely the GeForce RTX 3060 8GB, the GeForce RTX 3060 Ti with GDDR6X, and the GeForce RTX 3070 Ti with GA102. These graphics cards are currently planned, but it is unclear when they will be released.
