One of the more interesting consequences of GPUs being built on TSMC’s 28nm process for an extended period of time is that it has forced both vendors to compensate and compromise in order to have product lines that cover the nearly 5 year span. Traditional upgrade cycles got thrown out of the window, and instead we saw a number of refreshes and updates, culminating in both AMD and NVIDIA taking their top GPUs right to the 28nm reticle limit of ~600mm2. Such large GPUs have typically been the crossover point between graphics and compute parts, incorporating high-end features such as ECC memory and faster double precision (FP64) compute capabilities. However for the reticle riders, AMD and NVIDIA went another route, building what is arguably the ultimate graphics GPUs with the highest FP32 performance possible.
