Intel unveiled plans for a prototype of their discrete GPU at the San Francisco ISSCC (IEEE International Solid State Circuits Conference) late last week. The 14 nm dGPU, which is still in an early prototype stage, features 1.5 billion transistors and is clocked between 50 - 400 MHz, which may hint at a focus on efficiency over raw power.
