Although the AD102 Founder Edition PCB may support up to 28 additional phases, the RTX 4090 graphics card only has 23 of them. This implies that NVIDIA might continue to employ this board layout for even more efficient GPUs, such as the speculated GeForce RTX 4090 Ti.
Overall, the design of the PG136D (board number 4090 PCB) is nearly similar to that of the RTX 3090 Ti Founders Edition (PG136). NVIDIA utilises the same board number, despite the fact that the layout has changed. For starters, the power input section has been upgraded, and larger chokes have been installed. Another noticeable difference is the absence of an NVLink connection since the RTX 40 series no longer supports hardware multi-GPU systems with SLI technology.
In terms of the GPU, we can now compare Ada and Ampere GPUs, which are recognised as the flagship processors for each version of the GeForce RTX series. In comparison to the 8nm GA102, the Lovelace CPU, which was built using 4nm manufacturing technology, possesses 18432 CUDA cores and 2.7 times as many transistors. Despite these improvements, the GPU is 20mm smaller.
However, the RTX 4090 will be made available on the 12th of October. More information will be released tomorrow, along with the first independent reviews highlighting NVIDIA’s own Founders Edition.
