Pictures of the NVIDIA RTX 4080 PCB have been leaked to the web. There are several missing parts on this PCB. Only 17 of the 27 phases are being used, which shows that this board is ready for even more powerful AD103 graphics cards like the rumored RTX 4080 Ti.
The size, shape, and arrangement of the cooler mounting holes on the asymmetric PCB are all the same as those on the RTX 4090. This implies that if any board partner uses this board, adopting the current cooler will be considerably easier. However, we have yet to see an RTX 4090 with a V-shaped board because NVIDIA also makes a rectangular design that AIBs like better.
8 GDDR6X memory modules surround the AD103 GPU on the PCB. This area has been changed the most compared to the RTX 4090 FE PCB. The RTX 4080 features a 256-bit memory bus; therefore, each module has 2GB of capacity for a total of 16GB VRAM. It is also important to note that this card’s memory clock speed is 22.4 Gbps, not 23 Gbps, as previously claimed before Ada Lovelace GPUs were released. This is the fastest RTX 40 card available.
The card has a 16-pin 12VHPWR power connection positioned in the same location as the RTX 4090. It’s worth noting that virtually all RTX 4080 cards will ship with a 38-pin to 16-pin adapter rather than a 48-pin adapter like RTX 4090 cards. Although some modified variants can reach 380W, this model’s TDP is set to 320W by default.
The RTX 4080 has 9728 CUDA cores, a 5% decrease in core count from the complete AD103 GPU. This is in contrast to the reported RTX 4070 Ti with full AD104-400 GPU, which is expected to ship next year, according to the latest speculations. This SKU is said to be a renamed version of the RTX 4080 12GB, which NVIDIA had to stop making because of constant criticism.
The NVIDIA RTX 4080 16GB will be available on November 16th, with a starting price of USD 1,199.
