Lenovo Yoga 2 Pro: Performance, Heat and Noise

The Intel Core i5-4200U at the heart of this machine is a Haswell processor, but its two cores are clocked to just 1.6GHz – the hallmarks of a low-power part. Still, it’s got Hyper-Threading, a Turbo Boost top speed of 2.6GHz and 4GB of RAM. That’s enough for PC Mark 7 and GeekBench scores of 4,619 and 4,427: comparable speed to the Samsung and Apple, and enough to ensure that applications load and run smoothly – even if they’re more demanding work tools.

In several other key areas, the Lenovo can’t match the MacBook. Both laptops have 128GB SSDs, but the Lenovo’s drive returned sequential read and write scores of 484MB/s and 129MB/s – a good first result undermined by a dreadful second score. The MacBook, conversely, uses PCI-powered storage to hit 709MB/s and 557MB/s. The Lenovo is faster than a hard disk, but hasn’t got the pace of the MacBook – so it lags behind across the board, from application loading to system booting.

The Lenovo has an Intel HD Graphics 4400 chipset but, again, Apple is better thanks to its HD Graphics 5000 core. The Yoga scored 36,515 in the 3D Mark Ice Storm benchmark and then 574 in the tough Fire Strike test – but the GPU used by Apple has been clocked elsewhere as scoring 39,288 and 745 in the same benchmarks.

Both chips are only good enough for casual gaming and light graphical work, but Apple undoubtedly leads the way in this department.

When idling and running less intensive tasks we had no noise issues, but that’s not the case with more demanding software. During tougher benchmarks and stress-tests the fan was noticeable in our quiet office. It’s not as loud as the Kira, and temperatures never hit hazardous levels, but it’s still obvious noise.

Lenovo Yoga 2 Pro: Battery Life

There’s not much room for a battery inside the Lenovo’s svelte chassis, so it’s no surprise that its benchmark result was mediocre. We loaded Powermark and ran our benchmark – which involves video chat, web browsing and idling – with the screen at 40% brightness and Balanced power mode selected.

The Yoga lasted for six hours and 30 minutes in our test. That’s better than fully-fledged work notebooks and it’s better than many budget hybrids, but it’s 90 minutes less than the Samsung, three hours behind the Toshiba Kira, and almost half the longevity of the MacBook Air and its bespoke test.

That means that the Lenovo will only see its way through a full day of work if you’re careful with battery management. One glimmer of hope is the 41% battery yield after thirty minutes of charging – that’s good for a reasonable 2 hours and forty minutes of use.

Thanks for the review. I have one and think it is great. Agree about the screen resolution and how windows handles it - I run it at 1920 x 1080 because an app I use simply doesn't scale at all and is unusable at full resolution. Other than that it does everything I want. I agree it works best as a laptop and that's how I use it most, but there are times when the tablet (and other hybrid modes) are really useful, thus it was the best device that I found that met my requirements. And it looks cool in orange! lol

A few errors in your review around the specs available though!!. The base i5 model (at £999) has a 256GB SSD (not 128GB as your mention). I don't think the 128GB version is available in the UK. Also there doesn't appear to be an i3 version at all (maybe there was at launch?) The top of the range is actually £1300 and includes a 512GB SSD (not 256GB as you state - there is a 256GB i7 version - but that is £1100).

surface 3 looks to be a better bet

Wow, what a great insight! Depends what you are looking for. And spec for spec the Surface 3 is more expensive. I think if you want more tablet than laptop rather than more laptop than tablet then you are probably right.

Got this laptop for my girlfriend and we are totally in love with it. Connectivity is an issue though, so we plan on getting a USB 3.0 dongle. We have the i5 128Gb version, which is a European model. Wi-Fi speeds seem to be sufficient, but range could be better. Shame about a lack of Ethernet dongle.

Strange thing is that the keyboard layout is different than the one pictured in your review, with the return key actually being double-height. Hence there's no real keyboard layout issues with the European model.

Overall, i'd give it a strong 9/10. It's light, slim, fast and good-looking :)

does text look blurry when you downscale it to 1920x1080?
