GeForce RTX 4080 may be equipped with 9728 CUDA cores
Recently, Twitter user @kopite7kimi revealed that the GeForce RTX 4080 is equipped with AD103-300-A1, has 9728 CUDA cores, the corresponding number of SMs is 76 and has 16GB of GDDR6X memory with a rate of 21Gbps. The PCB design is PG136/139-SKU360, the power consumption of the entire graphics card is about 420W, and the 3DMark Time Spy Extreme score is about 15,000 points, which is about 35% higher than the GeForce RTX 3090 Ti.
Compared to the rumored 10,240 CUDA cores or 80 SMs in the past, the specs are down. Considering that Nvidia switched from Samsung to TSMC this time, coupled with the advanced process, the core frequency may be greatly improved. Samsung’s 8nm is strictly an optimized version of 10nm, which lags behind TSMC’s 7nm process node, while Nvidia skips the latter this time and advances to the 5nm process node, which theoretically will have a qualitative leap.
