Check out our guide to the best laptops.The 15.4' MacBook Pro Laptop Computer with Retina Display & Force Touch Trackpad from Apple is a powerful notebook computer with an innovative, ultrathin, ultraportable aluminum unibody design. After all, the mid-2015 model can't be considered ot innovative by Apple's standards, but the largest of Apple's notebooks is still a stunning Mac and a total powerhouse in general. It seems like this MacBook hasn't really moved on, but tiny tweaks ensure it's still a great machine. All this adds up to a machine that's been slightly tweaked to eke out every last bit of performance from components that are looking a little aged. As for battery life, we gained an extra hour in our streaming test, which is not to be sniffed at. Write speeds were in the region of 1.2 times faster – still very pleasing.ĬPU performance was also not far from last year's 2.5GHz model, only really losing out on single-core performance.

Blackmagic's Disk Speed Test brings to the fore Apple's claim that the flash storage in this new model is up to 2.5 times faster, delivering sequential read speeds of up to 2.0GBps (we recorded nearly 1.8). For example, frames per second in Unigine Heaven 4.0 were down from 11 to 7.5, but in our Arkham City tests, the frame rate was slightly up from 46 to 49, yet down a fraction at 19 rather than 23 when running at the display's native resolution.Įlsewhere there are some clear wins.
