2018 MacBook Pro 15" 2.6GHz I7 6 core, 512GB SSD, 16GB DDR4, 560x graphics, Space GreyApple hit it out of the park this year with the inclusion of the 6 core 8th gen Intel processors. Speedier DDR4 memory and insane SSD speeds  help as this is 1 of the fastest Mac's you can get, all in a nice portable size with a great screen. The discrete Radeon 560x graphics with 4GB helps with video editing and other tasks. Battery is better than last years models as well.I originally purchased the 13" 2018 MacBook Pro with i5/512GB SSD/8GB LPDDR3, but quickly found that the screen size was not for me. Its a pound lighter and little smaller, but I don't find carrying the 15" to be bothersome. Apple has done a great job at getting the build quality of these MacBook's down. While the 13" was fast and fluid, the smaller screen size is what ultimately made me switch. Of course the 15" feels snappier and smoother thanks to the 2 extra cores, faster DDR4 memory, and the discrete graphics. Both machines for 2018 are great upgrades over last years model.
