NVIDIA’s impending GeForce RTX 4080 “Ada,” a replacement to the RTX 3080 “Ampere,” supposedly comes in two unmistakable variations in view of memory size, memory transport width, and perhaps even center design. MEGAsizeGPU reports that they have seen two reference plans for the RTX 4080, one with 12 GB of memory and a 10-layer PCB, and the other with 16 GB of memory and a 12-layer PCB. Expanding quantities of PCB layers empower more prominent thickness of wiring around the ASIC. At debut, the lead item from NVIDIA is supposed to be the RTX 4090, with its 24 GB memory size, and 14-layer PCB. Evidently, the 12 GB and 16 GB variations of the RTX 4080 component unfathomably different PCB plans.

We’ve known from past endeavors at memory-based variations, for example, the GTX 1060 (3 GB versus 6 GB), or the later RTX 3080 (10 GB versus 12 GB), that NVIDIA goes to different switches to separate variations, like center arrangement (quantities of accessible CUDA centers), and the equivalent is almost certain with the RTX 4080. The RTX 4080 12 GB, RTX 4080 16 GB, and the RTX 4090, could be NVIDIA’s solutions to AMD’s RDNA3-based replacements of the RX 6800, RX 6800 XT, and RX 6950 XT, separately.
