Iris Plus Graphics 645 vs UHD Graphics 615
When choosing between Iris Plus Graphics 645 and UHD Graphics 615, it is worth examining the specifications of the models in detail. Do they meet the recommended requirements of modern games and software? Storage capacity, form factor, TDP, available ports, warranty and manufacturer support are all important. For example, the size of a PC case can limit the maximum thickness and length of the card.
