Apparently 45% off, tons of RAM and SSD, i7, and weighs nothing. What's not to like? Personally I'm a massive fan of the colour scheme too. 1080P screen, which at 12 inches makes a lot of sense compared to jamming a 4K display in and using all your battery up.

Apple seem to manage battery consumption and processor temps ok on a very slim case with a quad core. A processors power consumption will be based on the tasks you carry out so doing things that the duo core is compatible of will consume the same power. But a quad is more flexible because it allows more power instense tasks to be carried out. The price of duo cores should be lower but if silly consumers pay the prices they sell at they will never really drop


I understand the point you are trying to make, but your logic and understanding are completely flawed.

The 7700HQ ihas a TDP of 45w, whilst this CPU has a TDP of 15w. The 7700HQ may well consume the same amount of power at idle than this CPU does at its max TDP.

A quad-core is undoubtedly more powerful (and flexible, as you state), but you couldn't put it in a chassis like this (or a Macbook, or XPS13), and be able to cool it sufficiently, or cram in a battery that will power the thing for more than an hour or two, without severely gimping the thing. That's why this CPU exists.

The quad-core does not in itself allow more 'power-intense' task to be carried out, but it will do them quicker, at the expense of heat generated and power consumed.

Apple do indeed have a quad-core I7 in a thin and light body, but that's £2k of engineering, but the fan is on most of the time, and get's pretty intense under load.

Low voltage chips tend to have lower yields, which drives the price up.

For power saving and size... that is my guess.

I wouldn't spend this sort of money on a laptop at the moment, the new AMD Ryzen Raven Ridge APUs launch soon and they look like they are going to stomp all over Intels party - 4 Zen cores with 8 threads and Vega graphics roughly comparable to an RX 530 all at 15w.

u processor for £800? No thanks. Id rather have a quad core + 8gb ram than a dual core +16gb ram.

well at least its got Pentium 4 and 768 resolution

Because it suits your use case? Generality speaking more cores = more heat, louder fans and reduced battery life. you could buy a decent quad-core machine for £800, but it won't be this size or have the same battery life.

This is probably on sale because of the 8th gen quad-core 'U' chips, but if you don't need the extra power, buying this dual-core version wmay well save you a few hundered quid.

It weighs less than a kilo, is super thin, and has a decent battery life. Most tasks you'd want to do on a lightweight ultraportable laptop won't need that much more CPU power. You're far more likely to be limited by RAM anyway, with a bunch of chrome tabs and whatnot open.

I use a Surface Book with dual core i5 as my daily laptop, which is ~20% slower than this and it runs intensive programs like MatLab and Solidworks reasonably well, and only struggles with the fact it only has 8gb ram.

I understand that but less power should mean less money.

It doesn't work like that. The super-low voltage chips are normally the pick of the bunch, and thus, more expensive, relative to performance. If thermals and power constraints were of no concern, we'd see 10-core Broadwell in laptops.

Also, try and find a new ULV quad core laptop for less. currys.co.uk/gbu…tml has half the storage, half the ram, lower build quality, about the same battery life and costs £100 more, for ~10-15% more CPU power that you are unliekly to use most of the time anyway.

Interesting point. I like AMD as a company, but at one can always wait for the next best thing. If you need a new laptop now, waiting a few months for an unknown quantity that may be better may not be the best idea. Ryzen is an excellent effort from AMD, but didn't quite live up to all the hype remember.

The first laptops with the APUs will be released in weeks, in the video I posted there are details of several already announced (go to 4:55). Not sure what you mean about Ryzen, it's been an astounding success for AMD (check their last financial results) and updates have sorted out pretty much all of the teething problems now, it's become the go to chip unless you need extreme performance in games and even then the gap is small.

I agree here. AMD seems to have an excellent APU on their hands so hopefully some good, cheap future laptops. Even if laptop comparable in cpu power, prices will be driven down by simply having some competition in the market. However if you cannot wait, it is a decent price for the specs and build quality. Heat added
