This is a little bit biased as the 4770k higher score is mainly from the onboard Integrated graphics scoring getting added on, when any one looking at buying these cpu's will never use the on board graphics, they will fit a much needed GPU for the job, IE gaming or editing/design etc. 4770k had a cheaper price back then, plus it has some more Instruction set's which can be helpful... But if you are going to be doing 3d design, video editing rendering or any graphical work like YouTube video editing the 2011 socket is 100% better with its Quad channel memory! And 3D open word gaming like Far Cry 5 and games like Rust that need loads of ram, 12gb min, 32-64gb recommended when live streaming. If you cant afford or just don't want to spend 3k+ on a brand new video editing PC/Mac... You can build a second hand PC for under a grand that will beat them to bits for editing YouTube videos! or gaming... Here is how: 2011 socket motherboard, I like the GigaByte X79 or X99 UP4 etc, but all the top makes like Asus ASI make great boards... A cpu like Gen 3 or 4, I7 3930k, 4930k, 4960k, 4970x. 64-128GB of ram is very cheap now! The new 2019 16" MacBook Pro use's a AMD Radeon pro 5500m which is rubbish, there are loads of better cards for $100-$200 like GTX 1660TI 6GB, or MSI Radeon RX580 8GB can be had very cheap on Amazon, or even a GTX 1080 TI 11GB! If you bench mark a pc like this agents the new MacBook Pro it will beat it meany times over rendering 4 or 6k
