Nvidia’s flagship Ada Lovelace architecture GPU specs: 18176 CUDA, 48GB video memory, power consumption 800W

The recent new version of AIDA 64 has provided support for NVIDIA’s GeForce RTX 4090, indicating that it is likely to be the first released Ada Lovelace architecture GPU. In the past period of time, there have been rumors that Nvidia may only release the GeForce RTX 4090 product in the GeForce RTX 40 series in 2022, and the rest will wait until next year.

Recently, Twitter user @kopite7kimi has brought the latest news, saying that the flagship Ada Lovelace architecture GPU is AD102-450-A1, with 18176 CUDA cores, the corresponding number of SMs is 142, with 48GB of GDDR6X memory, the rate is 24Gbps. The power consumption of the entire graphics card will reach 800W, and it may become the first public graphics card with dual 16Pin external power supply interfaces as standard. To cope with the higher design requirements, it enabled a new PCB design called PG137 instead of the PG139 of the GeForce RTX 4090.

Compared with the GeForce RTX 4090, this graphics card not only has 11% more CUDA cores but also has a higher-speed video memory, which can achieve a maximum memory bandwidth of 1.1 TB/s. It is unclear whether the graphics card equipped with this GPU is a GeForce RTX 4090 Ti or a new TITAN model.

New rumors point to Nvidia launching the GeForce RTX 4090 as early as October.
