MagyarDell Latitude 13 7320 Detachable Review: A Better Microsoft Surface Pro 7
Unveiled at CES 2021, the Dell Latitude 7320 detachable is just one of three models in the high-end 7320 series with the other two being the Latitude 7320 convertible and Latitude 7320 clamshell. Together, these models directly succeed the older 10th gen Ice Lake Latitude 7310 by introducing brand new chassis designs and newer 11th gen Tiger Lake-U options.
Latitude 7320 detachable SKUs range from $1560 USD if configured with the base Core i3-1110G4 CPU, 4 GB RAM, and 128 GB NVMe SSD up to $2540 USD if configured with the Core i7-1180G7 vPro CPU, 16 GB RAM, and 1 TB NVMe SSD. All options otherwise come equipped with the same 3:2 13-inch 1920 x 1280 touchscreen.
Direct competitors include other high-end Windows tablets or detachables including the Microsoft Surface Pro series and the Lenovo ThinkPad X12.

Case — Narrower Bezels Than The Surface Pro 7
Dell Latitude devices are built tougher than the typical Inspiron or Vostro while looking more understated than an XPS to better fit professional workplaces. Unlike many of its Latitude clamshell siblings, however, the Latitude 7320 detachable is not MIL-STD 810G compliant. The metal backing and Gorilla Glass front still feel luxurious nonetheless with just minimal flexing.
There are a couple of improvements we would like to see. The thin metal kickstand, for example, feels loose and so it tends to teeter when adjusting angles. The keyboard base also flexes more than we would like which negatively impacts the typing experience.
Overall dimensions and weight are very close to the 12.3-inch Surface Pro 7 meaning the Dell unit is able to integrate a larger 13-inch touchscreen without needing to increase the size of the tablet. It makes the thick bezels of the Microsoft Surface look even more outdated than it already is. We fully expect Microsoft to play catch up by introducing new Surface Pro models with narrower bezels in the near future.
| Latitude 7320 Detachable | Dimensions (mm) | Weight (g) |
| Tablet | 288.4 x 207.9 x 8.44 | 782 |
| Keyboard Dock | 284.2 x 215.6 x 5.1 | 342 |
| Tablet w/ Keyboard Dock | 288.4 x 215.6 x 13.54 | 1124 |
Connectivity — Thunderbolt 4 For All
Ports include two USB-C each with charging and Thunderbolt 4 support and a 3.5 mm audio jack. Extras like the SmartCard reader and uSIM tray are optional. Dongles and Thunderbolt-based docking stations are highly recommended to fully exploit the versatility of the two USB-C ports.
There is no USB-A port or SD card reader.
Communication
The Intel AX201 comes standard for Wi-Fi 6 and Bluetooth 5.1 connectivity. For travelers, 4G LTE with eSIM support is available if configured with the optional Snapdragon X20.
Webcam
The front 5 MP and rear 8 MP cameras are of much higher quality than the typical laptop webcam. Video recording, however, is limited to just 1080p at 30 FPS on both cameras with no 60 FPS option at all.
Security
Most Latitude features like vPro, fingerprint reader, IR, and a proximity sensor to automatically sleep and wake the device are available. A webcam shutter is conspicuously absent whereas it has become standard on most newer laptops nowadays.
Accessories and Warranty
The standard retail packaging does not include the detachable M20NCC folio keyboard or PN7320A active pen which costs an additional $200 and $70 USD, respectively. In comparison, the Lenovo ThinkPad X12 has the keyboard attachment and pen included by default. It would have been great to see a USB-C to USB-A adapter or cleaning cloth with the retail packaging.
A base three-year warranty comes standard much like on other Latitude 7000 series systems.
Input Devices — Not As Good As A Laptop
Keyboard
The typing experience on tablets with detachable keyboards has always been subpar or just average at best. The keyboard deck is usually thin and more susceptible to flexing than a standard laptop keyboard which causes key feedback and travel to be softer and shallower, respectively. The Latitude 7320 detachable keyboard doesn't do anything to address these drawbacks and so it doesn't feel noticeably better or worse than typing on a Surface Pro folio keyboard. It's fine for messaging and emails, but you'd be better off with a Latitude 7320 clamshell or convertible for longer typing sessions.
Touchpad
The Precision clickpad is relatively small compared to the larger clickpad on the XPS 13 (10 x 5.5 cm vs. 11.2 x 6.5 cm). Its texture is completely smooth save for just a bit of sticking when gliding at very slow speeds for more accurate control. Basic cursor movements and multi-touch inputs are otherwise reliable if not cramped.
Clicking on the surface returns a shallow and somewhat spongy click. Clatter is quiet as a result, but we would have preferred feedback to be firmer.
Display — Big And Bright
The 3:2 Sharp LQ130N1 IPS panel is the first to appear on our database. Its attributes are most similar to the 16:10 Sharp LQ134N1 panel on the XPS 13 7390 2-in-1 including the full sRGB coverage, bright 500+ nit backlight, and high ~1500:1 contrast ratio. Black-white and gray-gray response times remain slow and so ghosting is noticeable. Thankfully, this generally isn't an issue for browsing and video playback purposes.
ComfortView Plus is included to reduce blue light emissions and eyestrain similar to the latest XPS laptops. The feature works without impacting colors.

Colors are decent out of the box, but they could be more accurate given the full sRGB coverage of the panel. Calibrating the panel ourselves would result in better grayscale (DeltaE 4.4 to 1.6) and colors (DeltaE 3.83 to 1.97) and a more desirable gamma of 2.2.

Screen Flickering / PWM (Pulse-Width Modulation)
| Screen flickering / PWM detected | 2451 Hz | ≤ 42 % brightness setting |  |
The display backlight flickers at 2451 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 42 % and below. There should be no flickering or PWM above this brightness setting. The frequency of 2451 Hz is quite high, so most users sensitive to PWM should not notice any flickering. In comparison: 54 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18988 (minimum: 5 - maximum: 3846000) Hz was measured. | |||
Outdoor visibility is great when under shade. A bit of glare is always present which is to be expected from the super-glossy touchscreen. Keep in mind that maximum brightness will automatically drop from 521.8 nits to just 438.9 nits because the Intel Display Power Savings feature is enabled by default. Disabling this feature through Intel Graphics Command Center prevents this drop in brightness. You're going to want to squeeze every nit possible from the backlight for the most comfortable viewing experience when outdoors.
Performance — 11th Gen Tiger Lake-U
Users can configure with the Core i3-1110G4, Core i5-1130G7, Core i5-1140G7, or Core i7-1180G7 with vPro in contrast to the usual Core i3-1115G4, Core i5-1135G7 or Core i7-1165G7 options on most other Tiger Lake-U PCs. The Core ix-xxx0 SKUs have much slower clock rates than the Core ix-xxx5 SKUs. Our Core i7-1180G7, for example, has a base clock rate of 2.2 GHz compared to 3.0 GHz on the Core i7-1165G7. We suspect that the small form factor of the Latitude 7320 detachable prohibited Dell from using the faster Core i7-1165G7 or i7-1185G7.
Intel Iris Xe comes standard on all SKUs except for the lowest-end Core i3 option. We recommend avoiding the Core i3 SKU anyway due to its very low 4 GB of non-upgradeable RAM.
Our unit was set to Ultra Performance mode via Dell Power Manager prior to running any performance benchmarks below for the highest possible scores. Owners should definitely become familiar with the pre-installed Dell apps and their settings. Dell Optimizer, for example, is where users can toggle the proximity sensor to prevent the tablet from automatically sleeping.
Processor — Core i7-1180G7 Is Very Different From The Core i7-1185G7
Raw multi-thread performance is almost 40 percent slower than the average Core i7-1185G7 given the aforementioned significant clock rate differences between them. Performance is therefore in between the Core i5-1035G1 and Core i5-1135G7 as found on the Surface Go and Surface Pro 7 Plus, respectively. Single-thread performance remains excellent and on par with other Tiger Lake-U CPUs.
The Latitude 7320 Detachable benefits very little from CPU Turbo Boost much like on most other tablets. Running CineBench R15 xT in a loop shows flat results with no long-lasting performance boost during the early minutes of the test.

Storage Devices
Available options include 128 GB NVMe PCIe up to 1 TB all with self encryption (SED). Dell uses the shorter M.2 2230 form factor instead of the usual 2280 likely to save on space and weight. Upgrading the drive yourself is therefore possible albeit not as user-friendly as on a laptop. Our test unit comes with a mid-range 256 GB Western Digital SN530 with sequential read and write rates of about 2500 MB/s and 1000 MB/s, respectively.

GPU Performance — Iris Xe Makes All The Difference
Graphics performance is excellent with results that are just slightly behind the average Iris Xe 96 EUs in our database which is to be expected considering the slower Core i7-1180G7 CPU. Users upgrading from older Intel generation CPUs will see marked improvements over the usual UHD Graphics or even last year's Iris Plus. The GeForce MX series is still better and more consistent for gaming, but gaming isn't a focus for the Latitude.
If you plan on playing fast-moving games like Rocket League or Fortnite, then we recommend connecting an external monitor. The internal display suffers from noticeable ghosting due to its slow response times which impacts the visual experience.
