Click to EnlargeThe 13-inch MacBook Pro with Retina Display is remarkably thin and light for a notebook with a full-voltage Core i5 processor under the hood.

It crashed when we tried to get the in-game resolution up to 2,880x1,800 pixels, but ran at 75.4 frames per second at 1,440x900 pixels and 70.8 frames per second at 1,680x1,050 pixels.

Its 5.18 million pixels is quadruple the resolution of last-generation’s baseline 1440 x 900 MacBook Pro, and even a huge leap over the previous "high-res" option at 1680 x 1050.

While this is still a very high resolution for a 15in panel, it’s nothing outstanding and content is still being scaled, albeit superbly.

It's not an Ultrabook, but the 13-inch Toshiba Portege Z935 (2.5-GHz Intel Core i5-3210M processor, 6GB RAM, 5,400-rpm 640GB hard drive) outpaced the new 13-inch MacBook Pro with a score of 7,040.

Stepping up to the $2,799 model will get you a faster 2.6-GHz CPU and a whopping 512GB of storage.

It does notch the resolution down just a tad, to a still awesome 2,560 x 1,600, which is more than professional 27-inch monitors like the ViewSonic VP2770-LED offer, and you can’t go quad-core for the CPU – but for many, neither of these will be issues.

Specs-wise you get a choice of Ivy Bridge Core i7 processors, 8GB of RAM as standard, up to 768GB of SSD storage and Nvidia GeForce GT 650M dedicated graphics.

Either way, it’s backed by 8GB of RAM, which we feel is an excellent base-line for a laptop this powerful – and one that’s not upgradeable.
