Nvidia GeForce RTX 4090 specs: 16128 CUDA cores, twice the performance of the RTX 3090
Earlier news pointed out that the GeForce RTX 4090 will be equipped with AD102-300 GPU, the PCB is PG137/139-SKU330, and the video memory is 24GB GDDR6X, the video memory rate is 21Gbps, and the TDP is 600W. It is said that AD102 will have up to 144 groups of SMs, that is, 18432 CUDA cores, which is a 71% increase in size compared to GA102.
Recently, Twitter user @kopite7kimi further revealed the specifications of the GeForce RTX 4090, saying that the AD102-300 equipped with it has 126 sets of SMs, that is, 16,128 CUDA cores, which is a 50% increase compared to the GeForce RTX 3090 and doubles the performance. The news refers to the GeForce RTX 4090 with a TDP of 450W, which is lower than the 600W that has been rumored in the past. AD102 with full 144 groups of SM will be used for GeForce RTX 4090 Ti, and the memory rate will also be increased to 24Gbps, which is the model with a TDP of 600W or above.
The netizens who leaked the news expressed their disappointment with the RDNA 3 architecture, suggesting that Nvidia is actively lowering the specifications of the GeForce RTX 4090, which may be related to the performance of AMD’s new generation of graphics cards that did not meet expectations. About half a month ago, it was reported that AMD reduced the specifications of the Navi 3x series GPUs, reducing the number of stream processors by 20%, resulting in a decrease in the related expected performance.

In addition, it was previously rumored that Nvidia will release the Ada Lovelace architecture GPU in “early Q3”. This time there is also a more precise time. The first GeForce RTX 40 series will have three products, namely GeForce RTX 4090/RTX 4080/RTX 4070.
