The new 10th gen Comet Lake U and Y-series processors succeed Whiskey Lake and will co-exist alongside the 10nm Ice Lake SKUs. Comet Lake continues to build upon the well-refined 14nm process and will offer 6 cores and 12 threads in a 15W TDP envelope (Core i7-10710U), increased boost clocks, better sustained performance, and improved battery life. While Intel claims a fairly significant performance gain from the previous generation, our preliminary benchmarks show that may not really be the case.
