GeForce RTX 4090 with 2520MHz boost clock
According to the leaker, it appears that the NVIDIA RTX 4090 now has a base and increased clocks. The RTX 4090 is revealed to have a base of 2235MHz and 2520MHz with a physical clock of 2750MHz (same as the in-game clock).
Those numbers are impressive at once compared to the current RTX 3090 SKU. The base clock alone is 60% higher (vs. 1395MHz) and the boost clock is 49% higher (vs. 1,695MHz). This is indeed a noticeable upgrade over the Ampere series.
Given that the RTX 4090 is rumored to be configured with a core specification of 16384 CUDA, this means that with the said "actual" clock speed of 2750MHz, the card's arithmetic performance can reach 90 TFLOPS in a single-resolution workload. That's nearly twice the height of the RTX 3090 non-Ti.
Kopite also repeats previously shared specifications on the RTX 4080 and RTX 4070 SKU. Each SKU must feature a different GPU, either the AD103 (RTX 4080) or the AD104 (RTX 4070). It looks like the RTX 4080 will have a 256-bit memory bus and 16GB of GDDR6X memory clocked at the same speed as the RTX 4090. Meanwhile, the RTX 4070, which is supposed to have 7168 CUDA cores according to the latest rumors, will have a 160-bit wide memory bus and 10GB of RAM. of GDDR6 18 Gbps memory.
NVIDIA is now expected to unveil its RTX 40 series in September or October of this year. Initially, these three models will only be launched with the mid-range RTX 4060 which is coming next year around CES 2023.
