To see if this matters we sought out an application that does let you change this properly - SwitchResX, which costs about £17 including VAT. But an issue is that some applications can't fit as much on a screen as they technically could, and OS X's configuration utilities don't allow you to change that properly. The result? Ultra crisp text that looks the same size as it would on a non-Retina model. So what OS X does is render many assets at 1,440x900 pixels and then doubles those pixels to meet the display's native resolution.
Mouse cursors would get lost in a vast ocean of pixels. If the MBP was set to run a display at 2,800x1,800, text would be so tiny it would barely be legible. To understand what that is, it's important to know how Apple has tuned OS X for a high-res (or HiDPI) display. But there's a caveat that may affect a subset of users, or more specifically, applications. Looking at raw numbers, the late-2013 Retina MBP is extremely powerful whether encoding media or pushing it to its limits for 3D gaming. Meaningless without context, but the 2011 non-Retina MBP we have been using for comparison in this review came in at 11,745, an 18 percent difference in favour of Apple's new machine.

GeekBench 2 runs a series of intense computation tasks to determine performance capabilities of computers, and scored the new MBP at 14,275.

The new MBP took precisely two minutes to encode this file a 2011 non-Retina MacBook Pro with a 2.4GHz quad-core Intel Core i7 processor and 16GB of RAM converted the same file to the same output specification in two minutes and 38 seconds, a roughly 31 percent difference.īenchmarking the processor revealed further detail. In terms of raw computing horsepower we took an uncompressed video out of Final Cut Pro X - a 760MB file that contained a 90-second 25fps 1,920x1,080-pixel video clip encoded at 74Mbps - and set Handbrake v0.9.9 to encode it down in a single pass to a 10Mbps H.264 file at 25fps, maintaining the 1,920x1,080-pixel resolution. This is deeply impressive for a laptop, and one with a screen resolution so significantly higher than HD. Dropping down just a few settings from maximum to medium got those rates back up to the 30-60fps mark. At 2,800x1,800 pixels the game remaining playable with settings cranked to max, although frame rates did begin to appear to dip into the 10-20fps range. The same was true of Borderlands 2, which is more graphically demanding even than Portal. The game remained perfectly playable, with frame rates around 20-30fps.ĭropping those settings of course meant frame rates ramped up dramatically even at this high resolution.

This model as reviewed includes Nvidia's GeForce GT 750M discrete graphics chip, which alongside Intel's new Crystalwell architecture inside the 2.3GHz quad-core i7 processor meant we were able to run Valve's Portal 2 game at 2,800x1,800-pixel resolution, with all graphical settings including full anti-aliasing and texture detail, set to maximum. To drive this high-resolution panel Apple has paired some seriously impressive CPU and GPU specifications under the hood of its top-end configuration. But in practice it will make few people frown and it's not a cause for concern. It's like buying a really great pair of headphones and then listening to music downloaded from Napster a decade ago - music once audibly satisfactory suddenly sounds, for want of a better word, crap. Some websites still use lower-resolution imagery and a slight downside of the MBP's stellar screen is that it reveals inadequacies of older media, such as icons.
