Intel is finally getting some 10nm processors in decent volume to the market. Later this year, we can expect the first laptops with Intel's 10nm Ice Lake CPUs. Sites like AnandTech have done preliminary testing and you can read the site's conclusions over here. Overall, the conclusion seems to be that the processor performance isn't really exciting.
Some improvements have been made, but overall the CPU performance isn't really that much better than Whiskey Lake. You do get some new features though, and Ice Lake does excel in terms of graphics:
Of course, the one area where Ice Lake excels in is graphics. Moving from 24 EUs to 64 EUs, plus an increase in memory bandwidth to >50 GB/s, makes for some easy reading. It gets even better in 25W mode, for games that are CPU limited, but still don’t expect to be tackling AAA games at high resolutions. Despite Ice Lake being focused on the ultra-premium >1080p resolution market, you will still be gaming at 720p or 1080p at best here.
