They're both exceptionally quick machines with solid benchmark scores - the Dell's overall score of 90 in our application tests isn't far short of the powerful desktop chip we used as our reference result. There's very little to choose between the two machines in benchmarks: the Dell has a newer processor and slightly better GPU, but the MacBook has Hyper-Threading and better storage. Apple fights back in storage, too: the Precision has a 256GB Toshiba XG3 SSD that delivers speeds of 1.4GB/s and 1.1GB/s, but the MacBook's PCI drive delivered speeds of 3.1GB/s and 1.4GB/s - a blazing pace that we've yet to see anyone come close to matching. ![]() The Dell has 2,400MHz memory, which is faster than Apple, but its 8GB allocation is half as much as the MacBook offers. Those specifications are marginally better than the AMD Radeon Pro 450 inside the MacBook, which has 640 stream processors but a slower 800MHz core and just 2GB of dedicated RAM. It's a mid-range mobile chip tuned to the needs of work software, and it has 640 stream processors alongside a 1,093MHz core - a solid specification that also has 4GB of memory. ![]() ![]() Graphical grunt comes from the Nvidia Quadro M1200.
