Today it’s time to see the PCB of the Nvidia GeForce RTX 4090and as we already knew, there are no big surprises, since it is practically identical to the one we can find on the GeForce RTX 3090Tiremembering that this graph served as a preliminary test of what we will see in the new generation of graphics in terms of consumption, power supply (16-pin PCIe connectors), and of course, cooling systems vitaminized to face the increase in temperatures.
Specifically, the image shows us the PCB with all the components and the Nvidia AD102 chipset right in the center. There will be two variants of the PCB: the PG193 maintains the V-design seen on current GeForce RTX 30 Founders Edition GPUs and some custom-designed GeForce RTX 3090 Ti, while the PG136 offers a rectangular design, which should be the most adopted by companies, since it also involves lower production costs and greater wearability of current designs.
For the rest, the PCB diagram shows us all the components that give life to the GPU, but here we are interested to know what it will offer four video outputs: 3x of them are DisplayPort, expecting there to be at least a next-gen DisplayPort 2.0 and an HDMI port. strong points the absence of a USB-C connectorso goodbye the VR craze, you can create a Multi-GPU setup through an NV-Link connectorand is powered by a single 16-pin connector, capable of supplying up to 600W of power.
The Nvidia GeForce RTX 4090 is rumored to be based on the AD102 graphics chip with the new Ada Loveace architecture along with TSMC’s 5nm manufacturing process offering a configuration of up to 18432 CUDA cores.
For reference, the current high-end gaming GPU, the Nvidia GeForce RTX 3090 Ti, offers 10752 CUDA cores, so a GeForce RTX 4090 almost doubles the number of cores. This graphics chip would be accompanied by 24 GB of memory GDDR6X and all of that would result in a TDP of 600W.
