According to leaks from the Chiphell forum, the PCB photo of the NVIDIA GeForce RTX 5090 graphics card has been exposed. PCB, short for Printed Circuit Board, is one of the core components of a graphics card. It is an insulating board covered with electronic components and wires such as GPU, memory, power supply, and interfaces, which are connected together through soldering to form the circuit system of the graphics card.
This PCB photo shows that the RTX 5090 will use a large number of GDDR7 memory points and a huge BGA package designed for the next-generation Blackwell GB202 GPU. The GB202 GPU is the flagship chip in the Blackwell architecture, which will power the RTX 5090 and potentially future high-end graphics cards such as RTX 5090 Ti/RTX 5080 Ti. It is reported that the RTX 5090 will be equipped with a GB202-300 GPU, featuring 21,760 CUDA cores and 170 stream processors. The factory frequency of this graphics card is expected to approach 3 GHz. In terms of memory, there are 16 GDDR7 memory points on the PCB, confirming support for up to 32GB of memory. The arrangement of these GDDR7 modules is consistent with previous leaks, with speeds reaching 28 Gbps, providing up to 1792 GB/s bandwidth through a 512-bit bus interface, significantly increasing the 1008 GB/s bandwidth of the existing RTX 4090. The GPU and memory are expected to be equipped with about 30 VRM phases and more than 60 capacitors on the main PCB. Such powerful performance requires a large amount of power supply, and this compact PCB seems to be powered only by a 16-pin power interface, conforming to the latest 12V-2×6 standard. A single 16-pin interface can provide up to 600W of power, matching the maximum TBP of the RTX 5090 GPU. Further magnification of the PCB reveals the model number “PNT5090 v1.0” and “100-10145-DFAA-A02”. The RTX 5090 will feature two baseboard designs, PG144 and PG145 SKU30. The former is the reference design for the Founders Edition graphics card, while the latter is the reference design for AIB models. Despite the shorter PCB size, NVIDIA seems to have adopted a more standard design approach, differing from previous rumors.NVIDIA GeForce RTX 5090 is anticipated to be launched at the end of January or the beginning of February.
The RTX 5080 is scheduled for release in mid-January.
