Dell XPS 13 – Performance and Specifications

The Dell XPS comes in a variety of specification options. My review model came equipped with an Intel Core i7-7500U processor, a 256GB PCIE SSD, and 8GB of RAM. There are lower-specified models with an Intel Core i5-6300U processor, and you can also upgrade your storage to 1TB and plump for 16GB of RAM, an addition video editors will likely choose to make.

Performance is snappy thanks in part to the 2.7-3.5GHz dual-core processor, and partly thanks to the speedy SSD. The Core i7 in this machine is a dual-core chip with Hyper-Threading, which enables each core to be treated as two separate threads, allowing for better performance in intensive tasks such as video rendering. It’s a similar setup to that of the 13-inch MacBook Pro, although the base model Pro that costs £150 more than this XPS 13 only gets a Core i5 chip with a lower clock speed.

This showed through in benchmark results, where the XPS powered to GeekBench 3 single and multi-core scores of 3,600 and 7,675 respectively, soundly beating the MacBook, as you’d expect.

I also tasked our in-house video editor, Tom Honeyands, to produce two identical three-minute video reviews on both the Dell XPS 13 and the MacBook Pro, and while both handled the editing process in a very similar fashion, the Dell was over two minutes faster when rendering the video, taking just over five minutes to do so.

Something to consider is that the XPS 13 doesn't get Intel's Iris Graphics, making do with Intel HD Graphics 620. This means it'll be slightly slower than both the MacBook Pro and Lenovo IdeaPad 710S when working with video effects. None of these machines are for gaming, though, so while it will make a difference, all will offer a compromised experience.Dell XPS 13 1

The 256GB PCIE SSD is extremely fast as well, putting in a Crystal DiskMark read speed of 1,316MB/s and a write speed of 626MB/s. This is significantly slower than the MacBook Pro and will make a difference when loading large video files directly from the SSD, but in general use it’s hard to feel a difference between the two.

Dell XPS 13 – Battery Life

With the more power-efficient Intel Kaby Lake processors on board, the XPS 13 is still a machine you can trust to take you through to bedtime. I worked a full eight-hour day that consisted of sending emails and writing documents with the screen at a little over half brightness, and still had some to spare come home time.

It wasn’t quite so strong in our Netflix test, burning through 19% of its battery in a single hour of streaming at 150nits screen brightness.

Running Powermark, which is usually slightly less intense than an average day's work, the XPS 13 ran for 10 hours and 2 minutes, which is one of the best results I've seen in this benchmark.

Should I buy the Dell XPS 13?

Trusted has now reviewed three of Dell’s InfinityEdge XPS 13s and the recipe hasn’t changed a lot, although the base price for these models has risen from around £800 to £999. While a big step up, that isn’t completely out of line with the rest of the industry, where premium component pricing has taken a big upswing.

The model on test here is the most expensive Trusted has looked at in those three iterations, which is fitting considering the introduction of Apple’s even-more-expensive 2016 MacBook Pros.

Dell XPS 13

It’s at the high end that the Dell XPS really shines. The top-spec Intel Core i7 processor makes light work of HD video tasks while still sipping power in other tasks to make true all-day battery life a very real claim. It doesn’t have the wow factor that it did a couple of years ago, and it certainly doesn’t match the MacBook Pro for pure experience, but it’s a winner in every other way.

The Dell XPS 13 is more expensive than the likes of the Asus ZenBook UX310UA and Lenovo IdeaPad 710S, but it beats them both in terms of screen quality, build quality and SSD performance, as well as boasting a Thunderbolt 3 connector. If you rely on your laptop for serious work, the XPS 13 is the obvious choice.


Still the best Windows ultra-portable that money can buy.

Never buy a Dell computer. I have the XPS 13 and it was a great computer, until it developed a fault. After 6 weeks there is still no satisfaction from the service department, and they now refuse to honour the New Zealand Consumer Guarantees Act. Very poor company.

How did things work out for you in the end?

Seriously no one is bothered about the static noise it makes when you
are charging it? or by the fact, that it uses a lot of power when it's
in sleep (34% in 8 hours of sleep)?
It has been chosen the best
laptop by so many review sites. It is hard to imagine how bad are the other
laptops if this one is the best so far.

Brand new Dell XPS 13 three months ago. The Thunderbolt connection never worked quite right, but I was able to use it without it (even though it was a major selling point). One day the computer would not turn on. Worked, then didn't. Tech wasn't able to fix and had to be sent to depot. After a week at the depot, I get this message:

Hello Chad,

In summary, spent more so I could have the "best" laptop and got crap. Yay!

I bought a dell 13" XPS laptop in December 2015. It wouldn't turn on Jan 10 2017. I called dell and they told me that since it was over one yr, there was no warranty. I took it to a computer repair store and they said it needed a new mother board. Repair was going to be $500. One word of advice, don't buy these dell laptops unless you want a boat anchor. Dell after sales service and warranty is terrible. I bet I didn't use this piece of junk more than 30 times since it was new as I have a desktop.

If you only used it 30 times in over a year, why did you buy it? It seems like a waste of money to me.

I bought the XP 13 and received it last Wednesday. I spend Thursday, Friday, and Saturday loading Office and other software tools. I bought a video connector and an extra power cord. I was really impressed and liked the machine immensely.

On Sunday, I tried to start the laptop and it wouldn't come on. I checked on line and found a lot of people were having the same problem. Dell support had me try and hard boot a few times (hold the power button down for 30 seconds) and that didn't fix it. They then told me to take the back case cover off and disconnect the battery. The screws attaching the back plate are star screws in a size that no one would ever have at home. Took it to my local Radio Shack to see if they had a tool that would work and even they couldn't find a star screw that wouldn't strip out the screw.

Called Dell customer service back and got the run around before finally ending up with some completely useless support person who told me that I would have to wait two days to send it back (because it was a new purchase my service tag wasn't associated yet) and that it would take an additional 7 to 12 days to get it back. No guarantee that this wouldn't happen again.

I am calling the Sales line tomorrow and demanding full refunds for my computer, my expedited shipping, and all my accessories.

I'll by a Lenova before I ever deal with Dell again. Run away from Dell. Just run an never look back
