RTX 4090 PCB looks a batch similar RTX 3090 Ti

We person authoritative representation of the RTX 4090 Ti committee design. 

Up to 28 phases tin beryllium added to AD102 Founder Edition PCB, but lone 23 are installed connected the RTX 4090 graphics card. What this means is that NVIDIA could inactive usage this committee layout for adjacent much almighty GPUs, specified arsenic the rumored GeForce RTX 4090 Ti.

Overall, the plan of PG136D (board fig of 4090 PCB) is astir identical to RTX 3090 Ti Founders Edition (PG136). As you tin see, NVIDIA adjacent uses the aforesaid committee number, though the layout has changed. For starters, the powerfulness input conception has been modified, and bigger chokes were added. Another distinctive alteration is simply a missing NVLink connector, arsenic RTX 40 bid nary longer enactment hardware multi-GPU configurations done SLI technology.

As for the GPU itself, we tin present marque a broadside by broadside examination of Ada and Ampere GPUs, considered the flagship processors for each procreation of GeForce RTX series. Lovelace processor built utilizing 4nm process exertion has 18432 CUDA cores and 2.7 times the transistors compared to 8nm GA102. Despite those upgrades, the GPU is really smaller by 20mm².

The RTX 4090 officially launches connected October 12th. More details are to beryllium shared time with the archetypal autarkic reviews featuring NVIDIA’s ain Founders Edition.
