NVIDIA announced the 16nm Pascal GTX 1080 and GTX 1070 GPUs. The $599 GTX 1080 will be more powerful than Titan X, GTX 980 Ti, or two GTX 980s. Neither card uses High Bandwidth Memory like the top Pascal GPU, Tesla P100.
Intel's Broadwell-E flagship enthusiast CPU, the Core i7-6950X, is expected to have 10 cores.
AMD Zen mainstream desktop CPUs could have 6-8 cores. The architecture has moved from Bulldozer's Clustered Multithreading to Simultaneous Multithreading, which is closer to Intel's design and has two threads per core. Zen desktop CPUs will be released before laptop CPUs. There could be a 16 core APU in 2017.
AMD's 14 or 16nm Polaris GPUs will apparently be cheaper and cooler, rather than trying to compete with the GTX 1080's performance. The Radeon R9 490 could cost $300. The Polaris GPUs will not have High Bandwidth Memory, which will instead be added to 2017 Vega GPUs as successors to the Fury series.
Sony could launch a "PS4K" console using an AMD Polaris GPU and faster Jaguar CPU capable of playing the current PS4 games in 2160p instead of 1080p. It could also boost frame rates for the PSVR.
