The previous PCI-Express SSDs weren’t exactly slow, easily outstripping the mSATA drives found in most Windows laptops, but Apple has upped the internal PCI-Express interface from two to four lanes for 2015, doubling the available bandwidth.
Last year’s 1.4GHz Haswell CPU has been replaced by the 1.6GHz Intel Core i5-5250U, and along with it comes a new integrated GPU, the HD Graphics 6000, and as ever it’s possible to upgrade to a 2.2GHz Core i7 for a £130 premium.Īs I’ve found on other laptops, performance increases aren’t necessarily the order of the day here: Broadwell’s move to a 14nm process simply means the new CPUs generate a little less heat.Īpple’s decision to bring the supercharged SSD over from the 13-inch MacBook Pro is far more exciting.
