NVIDIA GeForce RTX 4090 & RTX 4080 Specs
Just now, Nvidia made public the first three graphics cards in its new GeForce RTX 4000 series. In the coming two months, Nvidia will release three top-tier graphics cards: the GeForce RTX 4090, the GeForce RTX 4080 16 GB, and the GeForce RTX 4080 12 GB.

NVIDIA RTX 4080 Founders Edition: 12 and 16 GB Models
Be wary that the differences between the two RTX 4080 variants go beyond just the amount of memory they support. Let’s begin with the more robust 16 GB model, which is also available in 12 GB. Here we have the AD103-300 GPU, which has 76 SM and 9,728 CUDA cores.
The clock rate of the GPU is 2505 MHz. Therefore, we have 16 GB of GDDR6X memory, but it runs at a speed of 22.5 Gbps. A total of 720 GB/s of data transfer can be handled by the 256-bit bus. Power dissipation is specified at 340W.
The AD104-400 is the GPU used in the 12GB version of the RTX 4080. Our SM count drops from 76 to 60, and we’re down to 7680.0 CUDA cores. However, there is a minor increase in frequency, and we now operate at 2610 MHz. The 12GB of GDDR6X memory runs at 21 Gbps, not 23 Gbps. When added to the 192-bit bus, our bandwidth increases to 504 GB/s.
NVIDIA GeForce RTX 4090 & RTX 4080 Price And Release Date
On October 12, 2022, you may get the Nvidia GeForce RTX 4090 for $1,599 at the recommended retail price. Both the GeForce RTX 4080 with 12GB and the GeForce RTX 4080 with 16GB of graphics memory will be available on the market in November 2022 with prices of $899 and $1,199, respectively.
