In Blackwell GPUs for GeForce RTX 50-series video cards, Nvidia will significantly increase not only the number of computing units, but also the clock speeds. New details about the flagship GeForce RTX 5090 have come from unofficial sources. It is reported that the base frequency of this model will be almost 2.9 GHz. For comparison, the current flagship GeForce RTX 4090 has this parameter of 2235 MHz.
It is quite possible that Nvidia has made changes to the mechanism of dynamic overclocking of Blackwell graphics processors, foreign colleagues note. Because of this, the difference between the nominal and boost frequency of the GPU may be smaller than in the current generation. However, the new Nvidia Blackwell graphics processors will certainly overcome the 3 GHz mark. By the way, in 2016, the “green” video cards required extreme cooling for this.
According to available information, the GeForce RTX 5090 will be based on the Nvidia GB202 graphics processor. Its maximum configuration contains 192 SM (Streaming Multiprocessor) blocks, which corresponds to 24,576 CUDA cores, and a 512-bit memory bus. In the case of the GeForce RTX 5090, a slightly cut-down version of the GPU will be used. The number of computing units in its composition has not yet been specified, but the memory bus width should be 448 bits.
The official presentation of the first Nvidia Blackwell gaming video cards is expected to take place at the end of this year.
