However, even if it is AD102, Nvidia with superb knife skills should also use the standard RTX 4090 and the “full blood version” RTX 4090 Ti respectively.
It is speculated that the RTX 4090 may enable 128 sets of 144 sets of SM units / a total of 16384 CUDA cores, supplemented by 96MB L2 cache / 384 ROP raster units.
Given that it uses TSMC’s 4N process, we speculate that its GPU frequency will be between 2.0-3.0 GHz. With 21Gbps @ 384-bit wide 24GB video memory, the bandwidth reaches 1TB/s equivalent to the RTX 3090 Ti.
In terms of power consumption, it is said that the nominal value of TBP is 450W (the final TGP power consumption may be slightly lower), and a single 16-pin connector is used for external power supply (the non-public version will obviously have a design that breaks through 500W+).
Second, the RTX 4080 or the slightly stripped down AD103-300 GPU enables 80 of the 84 SM units / has 10240 CUDA cores, with 64MB L2 cache / 224 ROP raster units.
The video memory is said to be 18Gbps @ 256-bit width, which is slightly lower than the 576 GB/s bandwidth of the previous generation RTX 3080.
It is said that the TBP power consumption of the RTX 4080 is close to that of the RTX 4090 (about 420W), but since the memory frequency is not so aggressive, the card may increase the GPU core frequency for higher graphics performance.
Finally, the RTX 4070 or AD104-275 GPU with 7168 CUDA cores is slightly higher than the RTX 3070 Ti with 56 SM units / 6144 CUDA cores, supplemented by 48MB L2 cache / 160 ROP raster units.
It is expected that the card will be equipped with 18Gbps @ 160-bit wide 10GB GDDR6 memory, TBP power consumption is about 300W, and the price may be higher than RTX 3070 / 3070 Ti. As for the truth, please wait patiently for the official announcement in the second half of 2022.
Recent rumors suggest that the RTX 40 series is expected to be released as early as 2022 Q3, but the new schedule may have delayed the release of the first three SKUs to 2022 Q4, and the mainstream RTX 4060 graphics card may not be revealed until early next year during CES 2023.
