The Dell XPS 15 9560 Review: Infinity Edge Part Two
by Brett Howse on July 31, 2017 8:00 AM ESTSystem Performance
Unlike some of the thin and light 15.6-inch devices that have been trickling out over the past while, which feature dual-core Ultrabook internals, Dell’s XPS 15 sticks to its heritage with a full quad-core processor with a 45-Watt TDP, and a discrete GPU in the NVIDIA GTX 1050. This is a lot more compute than any Ultrabook can achieve, and for those that need more oomph in their portable computing, the step up to a larger form factor device like the XPS 15 9560 could really help with a lot of productivity workloads.
Intel’s Kaby Lake processors have been a small step forward, with the same model 7 series CPUs offering higher frequencies than the 6 series counterparts. In the case of the review unit, that means the Core i7-7700HQ a few hundred MHz over the 6700HQ it replaces, with the latest model now offering a 2.8-3.8 GHz frequency range.
Dell also outfits the XPS 15 with 8 to 32 GB of DDR4, and a 500 GB to 1 TB HDD with 32 GB of Flash, or full PCIe NVMe SSDs in 256 GB, 512 GB, or 1 TB options.
To test system performance, the XPS 15 9560 was run through our standard laptop suite of tests. Comparisons in the graphs below are for similar systems, but you can compare the XPS 15 with any system we’ve tested using our Laptop Bench.
PCMark 8
PCMark tries to simulate real-world tasks, and is broken into several categories which stress different parts of the system. All components of a laptop can impact the results, with the Creative and Home scores weighing heavier on the GPU capabilities for the gaming sections. Here the XPS 15 9560 pulls a sizeable lead over its predecessor mostly thanks to the updated graphics capabilities.
Cinebench
Cinebench is a CPU workload, where more cores and higher frequencies lead to better results. The test can be run as either a single thread mode, or in a multi-threaded mode where more cores can make a substantial impact. It’s clear in the multi-threaded results where the dual-core machines end and the quad-core ones begin, and the latest Kaby Lake chip in the XPS 15 9560 is able to surpass all of the Skylake based laptops it is pitted against.
x264
This test is similar to Cinebench, where pure CPU grunt is required, but without the single-threaded option. Once again, the Core i7-7700HQ shows it offers a noticeable increase in performance over the previous generation.
Web Performance
Web browsing is arguably the most important metric of all, but here the testing gets a bit murkier. Browser scripting performance is one of the key factors in web results, so it is important to be as consistent as possible here. We use Microsoft Edge as the browser, but even then, updates to the browser over time can increase performance, so these results are always a moment in time.
Although not right at the top in all of these scores, the XPS 15 9560 performs very well on any web task, and with the quad-core architecture, should offer more scripting performance than any Ultrabook for most tasks.
Storage Performance
The Dell XPS 15 9560 review unit shipped with a 512 GB PCIe NVMe SSD. Samsung is one of the most prolific OEM SSD providers, so it was a bit surprising to see a Hitachi based SSD in this XPS 15. This appears to be a XG4 based SSD from Toshiba with planar TLC. It’s far from cutting edge by today’s standards.
Looking at the performance, it is certainly a TLC based drive, with decent read speeds, and typical, poor, write speeds. Larger models may have better performance, and smaller models will almost certainly have a performance deficit to this version. As with most machines, these may be multi-sourced as well, so your mileage may vary based on the model you are looking at. Checking around at the 9560 owners threads on the web, it does appear that some are shipping with the Samsung PM961, which would be a nice step up from this drive if you’re lucky enough to get it.

You know that this particular Killer is stock Atheros?Vatharian - Monday, July 31, 2017 - link
Don't worry, the this Killer AC is stock Atheros Q6147A, it's actually pretty good and capable network card. They certainly do not have means to develop new AC chipset from scratch. I had my reservations, but after extensive tests I conducted at work, the chipset beat Intel AC in nearly every category, except power draw.Notmyusualid - Wednesday, August 2, 2017 - link
Ladies - all this 'Killer hate' has to stop.I've been using them for years, and yes I had tons of issues. But you simply load the original Qualcomm driver, and they are just fine - if not wonderful.
I even think the Qualcomm part has better receiver sensitivity too...

Have you encountered any issues with your 9560. It seems like QC might be a bit over the place, as far as I've read.coolhardware - Monday, July 31, 2017 - link
Would be interested to know this as well. Dell seems to be slipping the QC arena.Garrett S. - Monday, July 31, 2017 - link
Laxaa,I just sent off laptop number 3 today. I haven't had one Dell XPS 15 9560 work as of yet. All were BRAND NEW, factory sealed from Dell. All had the same problem, where the screen would flicker on and off randomly like a strobe light in a dance club. Both brand new factory sealed units did this.
So, I ordered a 3rd laptop that was Dell manufacturer refurbished. Again, after a couple of hours of usage, the laptop screen started flashing/blinking rapidly on/off, randomly, sporadically. Honestly, it was like a strobe light at a club.

Laxaa, check out my verified purchase on Amazon (look under customer videos/pictures). My Dell XPS 15 9560 laptop review with 4k screen is a verified purchase and not a random review... (Verified Purchase means amazon is acknowledging that a human ordered the actual product, and it's not a random review).I posted videos of the strobe like effect that all 3 laptop screens have displayed. Here goes laptop number 4, 5, 6, etc...
How is everyone else ordering them? Brand new factory sealed are terrible from dell, and so are manufacturer dell refurbished. Is everyone ordering them from Vladimir in the alley, late at night, used?

Got mine a month ago at the Microsoft Store in Atlanta.4K screen, 32 GB RAM, 1 Terabyte SSD, Fingerprint reader.
It was factory sealed.
Microsoft has Dell manufacture a Microsoft Signature Edition.
Only Windows 10 is installed with necessary drivers and Dell utilities.
This means a clean installation with no bloatware!
Added 4 years of Microsoft Complete warranty including accidental damage.
Any needed replacements are done immediately from new in-store stock.
Unboxed and set it up in the store immediately after purchase.
Immediately did all the updates.
No screen flicker.
No bad screen pixels.
No screen bleed.
DaVinci Resolve Studio 4K H.264 real-time video editing is smooth with zero dropped frames.
So far mine has been literally perfect and I'm more than pleased.

Garret S: That sounds like it must be an environmental problem - something going on with your power lines or some kind of wireless interference; something like that. Have you tried any of them in a different location (e.g. go work at a library or a starbucks or whatever for a few hours)?Just running on battery can eliminate any potential issues from the AC lines.

I had the same issue. The screen would start flickering like crazy after a couple of hours of usage. However, updating to the latest Intel display driver sorted it out for me. Its been a almost a month now and there has been no flickering
