Dell’s XPS 15 (model 7590) is a take a look at of simply how a lot you’ll be able to jam right into a Four.2-pound pc. This newest iteration contains as much as an Eight-core “overclockable” Core i9-9980HK and a discrete GeForce GTX 1650 card. This is numerous scorching in a frame arguably now not constructed to deal with it. you’ll be expecting to peer in a gaming pc, now not a high-end, thin-and-light workhorse.
We all know why Dell most likely did it: to compete with any other high-end 15-inch pc that is filled to the gills, the MacBook Professional 15. That is not a gaming gadget both—each are methods designed for programmers, engineers, content material creators, and different computing-intensive pros. However the unhappy fact is maximum customers will evaluate the highest CPUs in each laptops, and purchase the only with the “quicker” CPU. So sure, if Apple goes to go the road with a Core i9, Dell is it sounds as if in a position to go it too, thermal barriers be damned. Our assessment will see if the XPS 15’s stretch was once definitely worth the sacrifice.
What’s out of doors: Similar as earlier than
First, we’ll get started off in essentially the most unremarkable space: the outside, necessarily the similar as earlier than, with a carbon fiber keyboard deck, aluminum best and aluminum backside. More than likely may now not inform the variation between outdated and new except for for the relocation of the webcam from the ground to the highest of the display screen. So sure, double-chin other folks, have fun.
The most important alternate is the processor. Whilst the former XPS 15 9570 featured an Eighth-gen 6-core Core i7, with an non-compulsory 6-core Core i9, the latest XPS 15 provides Intel’s latest Ninth-gen Eight-core Core i9—and now not simply any Eight-core CPU both, however the overclockable Core i9-9980HK.
Graphics bumps upward, too. The former best GPU was once a GeForce GTX 1050 constructed at the Pascal structure. The XPS 15 7590 maxes out with a GeForce GTX 1650 constructed at the more moderen Turing structure.
The remainder of the specifications of our assessment fashion flip the dial to 11 as neatly—larger, quicker, fancier. Listed below are the main points:
XPS 15 7590 Specifications:
CPU: Intel Ninth-gen Core i9-9980HK
RAM: 32GB DDR4/2666
Show: 15.6-inch 4K OLED @ 60Hz

The XPS 15 is still pleasant to upgrades. To get inside of, you’ll want to take away the fringe Torx screws and two Phillips-head screws within the middle. You’ll then gently take away the ground panel and get admission to two DIMM slots, an M.2, the battery, and a wi-fi module.
Dell XPS 15 7590 CPU Efficiency
Our first benchmark is the venerable Cinebench R15. It is a three-D modelling take a look at constructed on an engine offered by way of Maxon in its Cinema4D product. It’s just about a natural CPU take a look at and, like maximum visualization programs, it loves CPU cores and threads.
The efficiency of the XPS 15 7590 within the multithreaded model of this take a look at is solely remarkable. Our effects come with efficiency from 3 Ninth-gen Eight-core CPUs, plus two desktop Eight-core CPUs (one Intel, one AMD).
The Dell XPS 15 7590 has sufficient ponies to outrun the thicker and heavier MSI GE65 Raider in addition to the AMD Ryzen 2700-based pc on this take a look at. It is outpaced most effective by way of the a lot greater and far heavier Acer Predator Helios 700, and the beastly Alienware House 51m R1.
Even supposing Cinebench isn’t consultant of all multi-threaded chores, it’s a horny just right stand-in to gauge efficiency in programs the place Cinema4D is embedded, corresponding to Premiere Inventive Cloud. If in case you have an older pc, the uptick will also be vital: 45 % in comparison to the 6-core XPS 15 9570, and a crushing 123 % quicker than a Seventh-gen Kaby Lake pc.
If all you in reality do is administered Place of business and skim on-line, you in reality most effective care about single-threaded efficiency—and you almost certainly don’t want an Eight-core pc, as you’ll be able to see once we run Cinebench single-threaded. Once more, three-D modelling isn’t consultant of all software efficiency, however offers an concept of ways the XPS 15 will reply beneath a set single-threaded load.
The upper rankings of the Ninth-gen Core i9 laptops are there for all to peer. Alternatively, you must additionally understand that the Ninth-gen and Eighth-gen Core i7 laptops apply shut at the back of. Maximum can be hard-pressed to inform the variation between a Core i9 or Core i7 within the overwhelming majority of single-threaded duties corresponding to Place of business, Chrome and even maximum Adobe Photoshop routines, despite the fact that they’re somewhat quicker.
One factor with the benchmarks above is that they run too temporarily (inside of a couple of mins) to warmth up the CPU a lot. That’s why we use the loose HandBrake software to encode a 30GB document the use of the H.264 encoder. Even on our Eight-core CPU laptops, the duty normally takes in way over 25 mins to complete. That warms up the CPU and must expose any barriers within the cooling or chronic supply of a pc.
It’s right here that we see the XPS 15 7590 switch positions with the MSI GE65 Raider, which it beat in Cinebench R15. That thicker, heavier MSI GE65 can stay its CPU cooler and feed it with chronic higher than the lighter XPS 15 can. In reality, the MSI GE65 beats the XPS 15 despite the fact that it makes use of one step down in CPU fashions.
The thermal limits at the XPS 15 7590 put it uncomfortably with reference to the HP Omen 2XS (when the latter is ready to efficiency mode). We’ll dive additional into the thermal barriers of the XPS 15 and what you must be expecting afterward.
XPS 15 7590 Gaming Efficiency
The HandBrake exams provide you with a just right trace about what to anticipate in the event you attempt to recreation at the XPS 15. Whilst it isn’t formally a gaming pc, somebody having a look at its portions might understandably think another way. We would possibly not run it throughout the complete gauntlet of gaming exams, simply sufficient to turn you what it may (and can not) do.
First up: We ran UL’s 3DMark FireStrike to measure simply the graphics efficiency of the pc in DirectX 11. The end result isn’t a surprise: The XPS 15 slides in slightly below an Acer Nitro 7 finances gaming pc with the similar GeForce GTX 1650.
Transferring directly to to DirectX 12 efficiency, we additionally measured the XPS 15’s GPU the use of 3DMark Time Undercover agent, a more moderen take a look at with way more complicated graphics. In natural graphics efficiency, the XPS 15 7590 ties with the similar Acer Nitro 7 with the similar GPU. On paper, the XPS 15 7590 is the equivalent of extra thermally challenged GeForce GTX 1060 GPUs.
In Upward push of the Tomb Raider, we will be able to see the boundaries of the XPS 15’s smaller frame. The spacious chassis of Acer’s Nitro 7—and many of the gaming laptops that make up this checklist—is helping stay it with ease forward of the XPS 15.
Dell XPS 15 7590 Battery Existence
We’ll finish our authentic exams with an important metric to many: battery existence. We loop a 4K video with the pc in aircraft mode, with the display screen brightness set to rather vivid 250 to 260 nits. We additionally connect a couple of earbuds with the audio grew to become on about midway.
We truthfully didn’t be expecting a lot from the XPS 15 7590, as a result of its 4K display screen. Upper-resolution monitors typically lop a 3rd off of battery existence. With its 32GB of RAM and the remainder of its , we didn’t suppose the XPS 15 would compete in any respect.
As a substitute we had been pleasantly shocked to peer greater than 10 hours of run time from the XPS 15 7590. That’s merely remarkable for a 4K-equipped pc. The OLED panel most likely helped, as a result of OLEDs don’t use chronic for backlighting on black scenes. It additionally is helping that the XPS 15 7590 rocks an enormous 96-watt-hour battery.
However this is the highest pc on our checklist: the Dell XPS 15 9570 with a typical 1080p display screen, which hits 14 hours of run time. So sure, if you need most runtime, go for a lower-res panel.
We must be aware that video rundown exams are simple for contemporary laptops. Be expecting, say, internet surfing to chop existence by way of a 3rd or extra. Should you plan to edit video at the pass, minimize it in part no less than. Should you intend to play video games, don’t ever be expecting greater than an hour or two of battery existence on any pc. Cranking up the display screen brightness will kill battery existence, too. As all the time, your mileage might range.
Dell XPS 15 Thermal Throttling
We don’t in most cases get into the weeds of the thermal efficiency of a pc, however the XPS 15 7590 jams an Eight-core CPU and decently powered GPU right into a Four-pound, 6-ounce bundle. Is Dell asking an excessive amount of of this narrow chassis?
You most likely noticed a touch of the XPS 15 7590’s thermal barriers above in our HandBrake take a look at, the place the XPS 15 loses to the thicker and heavier MSI GE65 Raider regardless of the Raider’s “slower” CPU. To dig deeper, we performed 4 runs of HandBrake back-to-back. That’s principally greater than an hour of pegging the CPU at 100-percent usage throughout all Eight cores.
We recorded the pc’s telemetry throughout the run. The fairway represents the CPU’s temperature, the orange represents the clock pace, and the blue represents the wattage of the chip.
As you’ll be able to see within the chart under, the XPS 15 roars off at Four.4GHz on all cores. However as soon as the pc heats up, it starts to decelerate. The clock speeds fall again to Earth, with many of the take a look at operating within the three.3GHz vary. Ultimately the pc runs at its 45-watt TDP score however nonetheless remains above its base clock of two.3GHz.
For the second one and 3rd runs, you’ll be able to see the CPU’s temperature is warmer for an extended length, however it nonetheless strikes alongside. The fourth run has constructed up sufficient warmth inside of that many of the run is at 2.9GHz and a TDP score of 45 watts. There’s additionally now not a lot headroom left for Turbo Spice up on that closing run.
Frankly, this isn’t dangerous in any respect while you believe that we’re hammering all Eight cores of a Four.2-pound pc for greater than an hour with clock speeds at rather excessive ranges.
No longer all duties are confined to the CPU. We additionally sought after to peer what would occur to the XPS 15 when the GPU and CPU are each generating warmth. You recognize, like in a recreation. For that we recorded the CPU’s vitals whilst taking part in Participant Unknown Battlegrounds. The sport isn’t recognized for its complicated graphics options, however it’s for its CPU load, whether or not it’s to calculate recreation physics corresponding to bullet drop or execute positional audio modelling, amongst different chores.
Within the chart under, the orange is the CPU’s clock speeds, the grey is the wattage of the CPU, and the yellow line is the CPU’s temperature. We ran the sport at 1080p with Prime settings, which is one notch down from Extremely.
As you’ll be able to see, the clock pace kicks alongside locally of 4GHz for the primary 15 mins of the sport. At that time, the CPU falls into the a lot decrease equipment of one.4GHz for many of the recreation, with the CPU now in a low-power state of 10 watts. Sure, we’ll say that once more: 1.4GHz.
This, frankly, is the problem that has vexed the XPS 15 collection for a while: thermal and gear supply ceilings when all the parts are beneath so much. It’s principally a 75-watt TDP GPU and a 45-watt TDP CPU (with spice up taking it normally to 55 watts and better) vying for cooling and gear. Ultimately you run out, and one thing offers.
Something we sadly don’t have here’s a body charge hint. Surely body charges dropped, however we suspect it’s now not the have an effect on you’ll think going from, say, 2.6GHz to at least one.6GHz. Given the GeForce GTX 1650’s reasonable horsepower, a drop from 70 fps to 55 fps doesn’t in reality alternate the enjoy a lot.
We suspect many video games may hit this limitation (we additionally noticed it on Rainbow Six Siege). That worrying graphic must make somebody with a gaming bent believe the Alienware M15 M2 as a substitute of the XPS 15.
