Samsung Series 7 Ultra NP740U3E - Performance, Heat & Noise, Battery Life

By Alan Martin



Our Score:


Samsung Series 7 Ultra NP740U3E – Performance

With an Intel Core i5 1.8Ghz processor backed up by 6GB RAM and a 128GB SSD, the Samsung Series 7 Ultrabook flies in regular tasks. Switching between different browser windows and applications is smooth and snappy. Boot up and restart times are impressive as well, at under 10 seconds from cold, and less than 15 seconds from a restart. Its 4,399 PC Mark 7 score is marginally lower than the Microsoft Surface Pro, but not noticeably so.

The Series 7 cleared the lower level Ice Storm 3DMark gaming tests with no problems, getting into triple figure FPS on the easier tests as you’d expect with a 1GB AMD Radeon 8750M graphics card inside. On the mid-range Cloudgate tests, it fared less well with tests aimed at notebooks and home PCs, but still managed 20FPS for the most part and an overall score of 3,740

Samsung Series 7 Ultra NP740U3E 13

Of course, 3DMark is designed to push graphics cards, and often real world examples give a better idea of performance, so we installed Steam to see how it would deal with a couple of recent hits. We’re pleased to report that both LA Noire and Batman Arkham City were just about playable at 1,920 x 1,080 - although in the larger outdoor sections you would want to drop the detail and resolution for it to be completely smooth. We also installed Fallout New Vegas for an older game, and found exploring the expansive desert landscape smooth even with high detail.

In short, while it’s not aimed at gamers, the Samsung Series 7 Ultra NP740U3E is fast enough to play quite a few games new games at medium detail settings, and older ones at high quality settings. That's far more than you can say of most ultrabooks.

Samsung Series 7 Ultra NP740U3E – Heat & Noise

Because the base of the Series 7 is pretty thin, unsurprisingly it gets warm, even on simple activities. It’s not uncomfortable, and the underside takes most of the heat, so there’s no chance of burning your fingers while typing.

Noise wise, though, the fans are impressively quiet, and you’ll only really notice any noise at all if you’re in a completely silent environment. Impressively, even when running intensive 3D games, the heat doesn’t step up too much, and the fans don’t make much more noise either.

Samsung Series 7 Ultra NP740U3E – Battery Life

In the Powermark battery benchmark with the screen set to its default 40% level, the Samsung Series 7 Ultra NP740U3E lasted five hours and 53 minutes. That’s a decent result, but quite a long way from the very best ultrabooks.

Unfortunately, it’s not the quickest to refuel. Switched off and plugged in, the Series 7 regained just 20% of its juice with a half hour charge, around an hour and 10 minutes real world usage. It’s not the worst we’ve seen, but it’s significantly less than the 13-inch MacBook Air, which gained 40% of capacity – enough for nearly four hours of use – in the same test.

Indeed, the battery tests show that, though the price is similar, this is quite a different laptop to a MacBook Air or similar slim ultrabook. It just quite doesn’t last long enough for all day use, though for most people it’s more than good enough.

No reviews seem to pick up on the fact that only Apple designs their laptops with a smooth underside, so they are suitable using in bed etc.. Everyone else puts their laptop's vents there, making them unusable on a duvet or other soft surface. It's the sort of detail that doesn't occur when comparing specs on the web, but makes a potentially big difference to usability (and laptop life).

I agree. Although I'm not an Apple fan, I am surprised nobody else in putting their cooling vents in the screen hinge like Apple.


June 25, 2013, 5:02 pm

So is this an Ivy Bridge or a Haswell machine?


June 25, 2013, 6:50 pm

No mention of Haswell, I was nearly sold until the screen size, why is it that every manufacturer is obsessed with 13 inch screens !

I understand the necessity for portability , but what about those of us that want the portability but would actually like a screen you can do proper work on at journeys end, I am not an Apple fan but with every machine that is produced lately, under powered, over priced, Apple is becoming more of a viable option.


June 25, 2013, 8:30 pm

I cannot find the 8750m version anywhere - they all seem to be 8570m - quite a step down


June 26, 2013, 9:34 am

I don't understand your problem: this is an ultraportable machine, and 13" is the sweet spot for most people. That doesn't take away the fact that there are both 15 and 17" solutions available all over at less than apple's crazy £1500 minimum asked price (for a 5400rpm equipped machine even).


June 26, 2013, 12:31 pm

Thanks for the comment, I understand that there re both 15 and 17 inch variants available, my point was pointing to the fact I like this machine but would love it in either one of the aforementioned guise's, if you have a product number for the featured model in either 15 or 17 inch I would appreciate your forwarding me the details, I have just purchased a Chronos 7 Notebook1TB NP7705ZE i7 15.6", I am not sure if this is a top machine but it is one that stood out for me, but I would also like to purchase a second machine and the model that appeals is the one featured here, but as I have said, not with a 13" screen.
Many Thanks.

Actually, the Series 7 Ultra DOES have cooling vents in its hinge :)


June 26, 2013, 2:38 pm

Might this be what you're after: http://www.trustedreviews.c... ?


June 27, 2013, 3:43 pm

Yes, and all over the bottom too, which was my point.


June 27, 2013, 5:15 pm

In fact Samsung's own website only seems to list the 8570m which appears to be only half as fast in terms of FPS - so this is a very different proposition - is there actually a version with 8750m or is this a typo?


June 27, 2013, 7:19 pm

Looking at the photos, I'd hardly call that an ultrabook, it's way too thick.


July 1, 2013, 3:09 pm

There are a few exceptions, such as my Lenovo U300s, which has a flat bottom and vents through the keyboard (It runs cooler and quiter than my 2013 MBA too), but other than that I totally agree.

makes it unusable?? are you having a laugh?


July 3, 2013, 1:06 pm

Try using it on a soft surface, and let me know how you get on.

I don't know about anyone else but I'm confused. The review states repeatedly that the dedicated graphics is a Radeon 8750M however the specs here http://www.samsung.com/uk/c... state a 8570M.

The processor is stated as an i5 3337U - this is a third generation core and so NOT Haswell. This is fine it's just it was asked and it would be good to point out in the review for the technically minded.

The price? I can see costs as low as £699 (John Lewis) all the way up to £1000+ (Amazon) This seems odd to me for a laptop that is a standard spec and so can't be configured. By the way all these devices say 8570M for the dedicated graphics.
So either I've missed something or maybe Samsung is bringing out a revision with the 8750M.

Feedback from you guys would really help as I love the site and use your reviews to decide what gadgets to buy but in this case you've left me very confused.

My dream laptop


July 30, 2013, 7:11 pm

The Sony Vaio Pro also have the fans on the hinges...


July 31, 2013, 2:25 pm

The just-released 11"/13" ones? Fair enough, though even they still have a side vent, which is almost as easy to block with a duvet.

Does anyone know if the Samsung series 7 has a built in surge protector?

WHAT?! Apple designs laptops suitable for using in bed? Only if you live in Siberia!!!

This had the right combination of graphics performance, form factor, etc - but seems to have been dropped by Samsung just a few months since this review, and I can't fond it anywhere. Any similar products/suggestions?
