Design and features

The X12 Detachable borrows heavily from the Surface Pro's design, so it's no surprise that these two devices are physically quite similar. They're both 2-in-1 PCs with a detachable keyboard, held in place with a series of magnets. These aren't wireless keyboard and must be attached by pins to communicate with the tablet. Each device has a fold-out stand on the back to prop up the display portion.

The Pro 7+ and X12 Detachable are both built into a sleek magnesium chassis. They weigh about the same without a keyboard attached, and the dimensions are likewise nearly identical. You can get the Pro 7+ with Platinum or Matte Black color finish, whereas the X12 Detachable comes only in ThinkPad Black. The Pro 7+ has a smooth finish. The X12 Detachable goes with something called "Peachskin" that feels great underhand. If you're adding a Type Cover to the Pro 7+, you can branch out a bit with the available colors.

In terms of typing, both keyboards do well to simulate the feel of a full board. However, Lenovo's ThinkPad keyboard has better overall rigidity for a more stable feel. It also adds the TrackPoint system with physical mouse buttons and a red pointing nub. The Surface Type Cover still feels great, but if you're already coming from a ThinkPad, the X12 Detachable will definitely be more familiar. Keep in mind that the Type Covers are sold separately, whereas the X12 Detachable has one included in the price. You can use older Surface Pro Type Covers with the Pro 7 if you'd like to save money.

Ports differ between these two devices. The X12 Detachable includes Thunderbolt 4, USB-C 3.2, 3.5mm audio, and optional Nano-SIM. These ports set you up nicely for the future, but some might find the selection lacking compared to the Pro 7+. The Surface device includes USB-C 3.2, USB-A 3.2, a microSD card reader, 3.5mm audio, proprietary Surface Connect, and optional Nano-SIM. If you often work with removable storage, you will likely have to add one of the best laptop docking stations to the X12 to keep up. The Pro 7+ does include a proprietary Surface Connect port, which can attach to a Surface Dock without tying up any other ports.

All ThinkPads usually come with a ton of security features, and the X12 is no exception. Along with a dTPM 2.0 chip and Intel vPro CPU options, it has an IR camera, webcam shutter, fingerprint reader, and Kensington lock slot. The Pro 7+ also has an IR camera for Windows Hello and a TPM 2.0 chip, but it lacks a fingerprint reader, lock slot, and vPro CPU options.

Audio from the dual front-facing X12 Detachable 1W speakers is understandably underwhelming. This is a thin device without a whole lot of space for an impressive soundscape. The Pro 7+ is similar, though its dual speakers hit 1.6W each and have Dolby Atmos tuning. If audio quality is of utmost importance, you're betting off with the Pro 7+. As for cameras, both devices have a front-facing 5MP camera and a rear-facing 8MP camera.

For easy connectivity, both laptops come with optional 4G LTE connectivity, Nano-SIM slot, eSIM capabilities, Wi-Fi 6, and Bluetooth 5. Note that the Pro 7+ comes only with a Core i5 when opting for LTE, whereas it seems LTE can be added to any X12 configuration.

Display and inking

These devices come with one 12.3-inch touch display option at a 3:2 aspect ratio, though the Pro 7+ boasts more impressive specs. The Pro 7+ goes with a 2736x1824 resolution, whereas the X12 sticks with 1920x1280. You'll still get a great picture from the X12 Detachable, especially with an anti-reflective finish, but it doesn't have nearly as much pixel density as the Pro 7+. The Surface device goes with a glossy finish that will have you dealing with more glare.

The Pro 7+ tops out at about 410 nits brightness, whereas the X12 hits 427 nits. As for color reproduction, expect 98% sRGB, 73% AdobeRGB, and 72% DCI-P3 from the Pro 7+, and expect 100% sRGB, 75% AdobeRGB, and 78% DCI-P3 from the X12. Either one is going to look great handling productivity work and even some photo editing.

These devices are as comfortable acting as tablets as notebooks, so inking capabilities are a given. The X12 Detachable includes a Lenovo Digital Pen with 4,096 levels of pressure sensitivity, plus you can upgrade to the Lenovo Precision Pen for about $60 if you need tilt support for shading. Both use Wacom AES tech.

The Pro 7+'s Surface Pen comes separate and generally costs more, though it does provide a stellar inking experience. It has 4,096 levels of pressure sensitivity, uses N-Trig tech, and tilt support. If you're artistic and want to use one of these devices for drawing and sketching, the Pro line is still a better option, especially when you add a Surface Dial for easier control over drawing apps.

Performance and price

Two major differences in performance hardware are the Pro 7+'s removable and upgradeable SSD and the ability to get up to 32GB of RAM. The X12 Detachable tops out at 16GB, and there's no slot for easy access to the SSD. You'd technically have to take the tablet apart, which really doesn't seem like an enviable task.

Both devices have impressive LPDDR4x RAM, and both have M.2 SSDs that hit about the same speeds (Pro 7+ beats out the X12 in read speeds). Other than in the PCMark 10 synthetic benchmark, the Pro 7+ wins out against the X12 when using a Core i5 CPU. Why? The Pro 7+ uses slightly different 11th Gen Intel chips, with higher TDP. They don't offer vPro, but they do operate at a higher frequency. If raw performance matters to you, the Pro 7+ is the better choice. But that doesn't mean the X12 is far behind.

Here are a bunch of benchmarks that show where the X12 sits compared to the Pro 7+.
