The VideoCardz portal was provided with a photograph in the high resolution of the GéForce RTX 4090 flagship video card in the Foundations Edition. It turned out that the manufacturer had made few changes compared to the previous generation's flagship model.
According to the photograph, the new board allows up to 28 power phases. However, the reference version of the GeForce RTX 4090 accelerator received only 23 power phases for the processor and memory. This may suggest that NVIDIA can produce an even more productive video card model in the future. For example, GeForce RTX 4090 Ti or a new Titan.
In general, the design of the PG136D for the reference version of GeForce RTX 4090 is very similar to that of PG136, which is used by the reference GeForce RTX 3090 Ti. However, some elements have changed their location. For example, NVIDIA has changed the location and generally reworked the set of power elements of the video card, for example by using a larger-sized throttle. Another notable change is the missing NVLink interface. Recall that the GeForce RTX 40 series videos do not support configuration from several GPUs using SLI technology.
As for the AD102 graphic processor itself on the new Ada Lovelace architecture, it uses more advanced 5 nm production process, contains 18432 CUDA cores and 2.7 times more transistors than the GA102 GeForce RTX 3090 Ti chip, which is produced according to the 8 nm process, while the new chip is 20 mm2 smaller.
The official sale start of GeForce RTX 4090 is scheduled for October 12.
