Microsoft has refreshed its Surface Laptop line. The new Surface Laptop 4 delivers a number of changes but most of them can be classed as rather minor – for example it looks pretty much identical to last year's model. Perhaps the biggest change is that a choice of Intel and AMD processors are available for both the 13.5- and 15-inch models. Another change is the replacement of the Cobalt Blue finish option with Ice Blue. Considering the new processor choices first, the Surface Laptop 4 can be specced with a choice between either the 11th Gen Intel Core processors, or AMD Ryzen Mobile Processors with Radeon Graphics Microsoft Surface Edition (8 cores). Yes, Microsoft is still using Ryzen 4000 series APUs with Zen 2 cores.
