Dell XPS 15 7590 (OLED/i7-9750H/GTX 1650) Reside Evaluate — Have the Issues Been Fastened?

The brand new XPS 15 7590 makes a case for itself by sporting an non-compulsory OLED panel, Intel’s newest ninth technology 6 and Eight-core CPUs, Nvidia’s GTX 1650 GPU, and, lastly, an above-display webcam. As I wrote in an earlier editorial, nevertheless, whether or not or to not give the 4th revision of the XPS 15 an opportunity is likely to be a troublesome name in the event you’ve been beforehand burned by the road’s many points previously.

Because the XPS 15 has already been reviewed many instances beforehand, we direct you to earlier protection (XPS 15 9550, XPS 15 9560, XPS 15 9570 and long-term evaluation) for extra detailed details about the chassis, keyboard, trackpad, ports, and audio, as these haven’t modified since 2015. This reside evaluation will thus largely deal with the brand new UHD OLED show, sustained efficiency beneath CPU, GPU, and combined masses, and normal stability that can assist you decide if the doubtless closing revision of the XPS 15 utilizing this chassis is value your hard-earned cash.

This can be a reside evaluation, which means that I shall be updating the article with recent information as every part is accomplished. See log beneath.

Aside from the webcam’s place above the display, the XPS 15 7590’s chassis is unchanged from its predecessors. We recommend you learn our opinions of the 9550 and 9560 for extra detailed info on the appear and feel of this collection of notebooks.

Sadly, there may be nonetheless just one color accessible for the XPS 15, as nicely. There’s a particular “Titan Gray” end accessible for lid of the Precision 5540 (which makes use of the identical chassis), so it might have been good to see that choice for the XPS 15 7590 to assist spruce up the Four-year-old design and look of the 7590.

Keyboard, Trackpad, and Fingerprint Sensor

Coming from my ThinkPad P1, which has top-of-the-line keyboards you’ll find on a contemporary pocket book, the change to the XPS 15’s keyboard is a noticeable one ― however that doesn’t imply it’s all unhealthy. The keyboard on the 7590 is unchanged from earlier generations, and thus it’s the identical shallow-but-crisp 1.3mm stroke and suggestions.

Previously, I’ve discovered some XPS 15 keyboards to be a bit extra “mushy” in really feel whereas others appeared a bit extra sturdy (that is doubtless due to completely different keyboards from completely different suppliers within the manufacturing provide chain), however I might fee the keyboard on my unit to be on the firmer aspect of this spectrum: The keys are pretty secure and depress with out wobble, although the texture can’t be in comparison with the steadiness and easy motion of a superb ThinkPad keyboard.

By my estimation, the weakest side of the XPS 15’s keyboard is its shallow throw. You (or extra precisely, your fingers) will discover the abrupt bottoming-out as you kind. It isn’t precisely uncomfortable, however you received’t overlook that there are higher keyboards on the market. On a constructive be aware, nevertheless, there appears to be no concern with fast adjoining keystrokes (“obtain” popping out as “downloda”) not being detected, as regularly occurs with the ThinkPad X, P, and T-series. I’m able to kind between 90-110 WPM with none points in key-detection, which is one thing I’m blissful to expertise coming from the P1.

The XPS 15’s touchpad is identical Home windows Precision glass pad as earlier than, with full help for a variety of settings together with 1/2-finger tapping, 2-finger scroll and zoom, and three and Four-finger Home windows gestures.

My solely gripe with the touchpad is that there’s nonetheless no extra setting in Home windows to allow or disable palmcheck, with this setting as a substitute tied in with the “sensitivity” choice (highest sensitivity decreases the palm rejection and the keyboard typing delay after utilizing the trackpad, and vice versa). Because of this you’ll regularly both undergo from unintentional clicks whereas typing, be pressured to attend for a couple of break up seconds to kind after shifting the cursor, or must disable tap-to-click. I ended up disabling each tap-to-click choices to keep away from frequent annoyances whereas typing, which isn’t preferrred.

The fingerprint sensor is identical Goodix sensor built-in into the ability button because the 9570. The sensor works extraordinarily rapidly and precisely, studying prints efficiently in ~zero.2 seconds. This can be a welcome change from the non-integrated fingerprint sensor on my ThinkPad, which is safer however is frustratingly solely capable of learn my prints round ~10% of the time.

Display screen

A significant level in focus of this evaluation of the 7590 is its Samsung OLED panel, which is rated at 400-nits brightness and may cowl the DCI-P3 gamut. As an fascinating aspect be aware, DCI-P3 is the usual gamut for movie per the main manufacturing corporations, and as cell computer systems like notebooks, smartphones, and tablets are used increasingly for media consumption, producers are pushing DCI-P3 shows extra regularly.

The FHD matte non-touch and UHD shiny contact IGZO IPS panels additionally accessible on the 7590 are rated at 500 nits brightness (100 greater than final 12 months) every, however in any other case ought to have the identical working specs.

OLED shows are recognized for his or her wonderful distinction ratios, and this panel is not any exception.

Let’s get into the show then. Previously, I’ve discovered points with backlight bleeding, uncentered panels, and uneven brightness on the FHD and UHD screens within the XPS 15 collection. Due to the way in which the expertise works, OLED shows don’t undergo from backlight bleeding, however different defects are definitely attainable. Fortunately, this unit has a centered panel and no concern with uneven brightness.

Even the most effective IPS panels present a bit little bit of backlight bleed or glow, however OLED skirts these limitations by the pixels being individually lit.

Nevertheless, there’s a (comparatively) small concern with this OLED panel that appears to be reported by most customers as nicely, and that could be a slight graininess or “banding” when displaying sure colours equivalent to lighter shades of gray. The problem appears to be most outstanding when displaying the sunshine shade of gray proven beneath. That is the one OLED laptop computer I’ve had an opportunity to check to this point, so it’s a bit early to inform whether or not the issue will get higher over the panel’s lifespan or if this isn’t a difficulty generalized to all items. I’ve learn on-line that OLED panels obtain higher uniformity after 200 hours or so of use, however take into account this unconfirmed for now.

There are some lighting/compression artifacts on this image, however most of what seems to be dithering is definitely banding artifacts from the OLED panel.

CPU benchmarks

  Cinebench R15 Single
Cinebench R15 Multi
Cinebench R15 10-Loop Common
XPS 15 9560 (i7-7700HQ) 157 735 680
XPS 15 9570 (i7-8750H) 173 1117  1128
XPS 15 7590 (i7-9750H) 176 1088 991
XPS 15 7590 (i7-9750H) w/ undervolt

As we will see by the desk above, the XPS 15 7590 unit I’ve appears to carry out worse in Cinebench R15 multi than the 9570. By inspecting the info from HWiNFO charted beneath, we will see clear temperature spikes as much as 99C adopted by a corresponding drop in CPU frequency because the system thermally throttles to MacBook-like clocks (sorry, I couldn’t resist).

Temperatures and clocks throughout Cinebench R15 Multi 10-loop take a look at through HWiNFO.

GPU benchmarks

This 12 months’s XPS 15 makes use of Nvidia’s new GTX 1650 cell GPU. Although it lacks the raytracing cores of the RTX-series, it must be a reliable card and a stable improve over final 12 months’s GTX 1050 and 1050Ti.

  Hearth Strike (commonplace)
Hearth Strike (Graphics)
Unigine Heaven Four.zero (primary)
XPS 15 9560 (i7/GTX 1050) 5597 6400 2875
XPS 15 9570 (i7/GTX 1050Ti Max-Q) 6875  7584 3066
XPS 15 7590 (i7/GTX 1650) 7597 9098
XPS 15 7590 (i7/GTX 1650) w/ undervolt

Operating a Firestrike Stress Take a look at of 10 loops yields a disappointing rating of 60.7%.

Whereas the Hearth Strike take a look at confirmed a stable rating that champed the GTX 1050Ti Max-Q, working the stress take a look at reveals one thing critically improper with the 7590’s capability to maintain GPU efficiency. HWiNFO charts reveal a frequent dropping of the GPU to a core clock of solely 300 MHz that doubtless contributes to this poor rating.

<extra testing to be completed>


Latency points have plagued the XPS 15 line for years, however Dell has made a variety of current makes an attempt to convey the issue beneath management so the 9570 and 7590 might be made appropriate for real-time audio processing. Sadly, my testing to this point has not yielded constructive outcomes.

It had been prompt to disable the devoted GPU, which I attempted subsequent.

Disabling the devoted GPU in machine supervisor didn’t appear to assist.

I shall be working extra assessments with completely different CPU settings over the subsequent few days.


The bundled Toshiba SSD places up fairly respectable efficiency, particularly in comparison with the slightly shoddy roughly 260 MB/s learn and write speeds of the Lite-On SSD that got here in my XPS 15 9570 final 12 months. As normal with SSDs, the upper capability the quicker the efficiency must be.

The 256 GB Toshiba SSD in my unit offers pretty sturdy efficiency regardless of its smaller capability.

Previously, Dell has shipped XPS 15s with Lite-on, Samsung, and Toshiba SSDs, with Samsung SSDs usually being probably the most performant. Sadly, which SSD and what efficiency you’ll get is simply luck of the draw.


Unscrew the 10 T5 and a couple of Phillips screws and you’ll have entry to all that may be upgraded within the XPS 15 9570. All the things that was true for the 9550, 9560, and 9570 remains to be true right here. The internals comprise an NVMe PCIe SSD slot (m.2 2280), 2 SO-DIMM slots, an m.2 NGFF slot for Wi-Fi, and, when you’ve got the 57WHr battery, a SATA III bay for two.5″ storage. In comparison with many ultrabooks, the XPS 15 has pretty good growth. Nevertheless, to compete towards contemporaries just like the X1 Excessive, it might be good to see a second NVMe PCIe SSD slot.

Emissions (noise, warmth) and audio system

Battery life

Roughly 7-Eight hours to this point utilizing largely dark-themed apps in addition to WordPress. Batterybar Professional measures roughly 1W extra energy consumption on common taking a look at a lightweight webpage vs a darkish one, however I shall be working extra assessments on it.

Value and availability


Fn + F7 (unobtrusive mode) appears to crash the OLED panel and require a restart to repair it.
