PCMark8 battery life - 154 minutes
The benchmarks tell all - this is one of the most powerful gaming notebooks we've come across in our reviews to date.
It's not showcasing the cutting-edge of mobile graphics right now - that accolade goes to the GTX780M - but for the price you won't find better. During the benchmarking test for Bioshock Infinite at maximum settings the P25 averaged around 36 frames per second, which is no mean feat.
The Asus G750JX offers almost identical performance, thanks to an almost identical specification, at a very similar price, although it doesn't have the super-responsive SSD to match and the Asus is a much bigger, heavier laptop (part of which is down to the bigger screen).
Although gaming laptops are never really intended to be left untethered from a mains charger, the P25 surprises in the mobile stakes with an entirely commendable 154 minutes of battery life, helped no doubt by its up-to-date Haswell processor.
When the P25 needs a lick of speed, the dual rear fans kick in and you can really feel a rush of air coming from the back vents. It's certainly no church mouse - this thing really makes a lot of noise, so you'll need a good pair of headphones to keep out the noise, otherwise you might get a headache after a while.
Unfortunately, while the speakers are loud enough to smother the fans, they're pretty much devoid of any sort of charm. There are no fancy audio big guns gracing the P25's specification sheet.
The Blu-ray drive - naturally - allows you to watch Blu-rays, which, when combined with the 'movie' setting of the Dolby Home Theatre v4 sound options in the speaker settings gives you a pseudo surround effect. It certainly gives the sound a boost for movies, but, even with the levels fine-tuned in the advanced options, it's hard to improve on the somewhat flat tone of the speakers.
In this day and age we'd expect to find an IPS screen, as is de rigour, but although Gigabyte's less-gaming-focused P35 model includes a more gaming-orientated IPS display, for richer colours and less reflection in most lighting situations, the P25 makes do with a slightly cheaper matte LED display. Some gamers prefer this for gaming, but in general, most manufacturers have moved to IPS, making this an odd choice.
It doesn't quite have the zing of an IPS and we noticed there's a definite gravelly look to it, though the majority of viewing angles on the P25 are absolutely fine, unless you're looking at the screen from the extreme ends of the straight-on spectrum of angles.
