78% Speed Claim Turns Boox Note X6 Into a Tablet Threat

78% is the number Boox wants buyers to remember before they see the full Note X6: that is the claimed performance improvement over the previous generation.

The company has revealed that its next E Ink notebook will use a 4nm Snapdragon 6690 processor clocked at 2.9GHz, according to Notebookcheck. The detail matters because Boox chose to tease the silicon before the full May 27 unveiling. That signals a shift in how the company wants the Note X6 judged: not only as digital paper, but as a more capable Android-based productivity device.

A 78% performance claim moves Boox beyond paper-like screen specs

Boox’s teaser reframes the Note X6 launch around speed. In older E Ink product cycles, the headline often sat with display size, front lights, stylus support, or whether the panel looked closer to paper. Here, the company is putting the processor near the center of the pitch.

That does not mean the Note X6 will behave like an LCD or OLED tablet. E Ink refresh behavior still shapes what users perceive as “fast.” A faster chip cannot erase the physical limits of the display. But it can reduce the non-display delays around the experience: loading, switching, processing, and keeping Android responsive.

MLXIO analysis: this is the more interesting angle. Boox is not merely saying the Note X6 has a newer processor. It is suggesting that compute performance has become a buying criterion for premium E Ink notebooks. That puts pressure on rivals that sell simplicity and writing feel as the whole story.

For broader lineup context, this follows Boox’s recent push around monochrome digital paper in Boox Bets on Monochrome with Note X6 Ahead of May Launch, while the company has also been active at the ereader end of its portfolio with Boox Shakes Ereader Market with Colorful Poke 7 Series.

The Snapdragon 6690 name hides a Dragonwing enterprise chip

Boox calls the Note X6 processor the Snapdragon 6690, but Notebookcheck notes that Qualcomm identifies the processor as the Dragonwing Q-6690. That naming gap is not just branding trivia. Qualcomm’s product page positions the chip for devices such as electronic cash registers, POS terminals, tablets, and smart displays.

The chip includes eight Kryo 7-series CPU cores, an Adreno GPU clocked at 1.15GHz, and a 6 TOPS NPU. It also supports Wi-Fi 7 and Bluetooth 6.0. Qualcomm also describes it as the world’s first enterprise mobile processor with fully integrated UHF (RAIN) RFID capabilities. RAIN RFID is a UHF RFID standard used for item identification and tracking; the source does not say whether Boox will use that capability in the Note X6.

That distinction matters. The Note X6 is a consumer-facing E Ink notebook, but its chip comes from a part family with enterprise device targets. MLXIO analysis: Boox may be choosing silicon with more headroom than a basic note-taking device strictly needs, either to improve Android responsiveness or to give itself room for features it has not yet disclosed.

Boox says the new chip offers a 78% improvement in performance compared to the previous generation.

The claim is strong. The open question is where buyers will feel it.

The confirmed spec sheet is still narrow, but the chip details are unusually rich

Boox has not published the full Note X6 specification sheet. The known facts are concentrated around the processor, launch timing, display type, and stylus support. The previous Note X5 gives a useful comparison point, but only where the supplied sources provide details.

The table shows both the opportunity and the blind spot. The Note X6 processor is far more clearly identified than the rest of the device. Display resolution, memory, storage, battery capacity, Android version, and whether all chip-level connectivity features appear in the final product remain unknown.

MLXIO analysis: benchmarks alone may not settle the Note X6 story. On an E Ink notebook, software tuning, refresh modes, power management, and memory configuration can matter as much as raw CPU numbers. A fast processor paired with limited RAM or conservative refresh behavior could still feel constrained. A well-tuned system could make the same chip feel meaningfully better even without turning the device into a conventional tablet.

Android gives Boox a different pitch from Kindle Scribe and reMarkable

The related reporting from Android Authority describes the Note X6 as an Android-powered rival to the Kindle Scribe, with a launch planned in China on May 27. It also says the teaser shows a monochrome display and stylus support, while full specifications remain mostly under wraps.

That Android angle is central to Boox’s differentiation. Kindle Scribe and reMarkable are typically discussed around writing focus, reading, and controlled software experiences. Boox leans into a more open Android model. Android Authority argues that Boox wins some users over with more flexibility than Kindle.

The trade-off is obvious. More flexibility raises expectations. If Boox sells the Note X6 around performance, buyers will expect the software to justify the silicon. Faster hardware can make Android feel less constrained on E Ink, but only if Boox manages refresh behavior, interface scaling, and battery draw well.

MLXIO analysis: the Dragonwing Q-6690 choice suggests Boox is not optimizing only for basic reading and handwritten notes. The company appears to be preparing a device that can carry a heavier Android identity. The risk is that E Ink buyers may not all want that. Some want fewer features, fewer menus, and less tablet-like complexity.

The May 27 launch still has several missing pieces

The biggest unknown is not the chip anymore. It is the product around it.

Boox still has not confirmed the Note X6’s final display size, resolution, RAM, storage, battery capacity, Android baseline, price, or launch markets. Android Authority says it is not clear whether the device will launch beyond China. GizNewsDaily also notes that Boox already sells the Go 10.3 Gen II lineup globally, including a standard model and a front-lit Lumi version, which could affect how the Note X6 fits outside China.

There is also no confirmed Note X6 Mini. The previous generation had a smaller Note X5 Mini with a 7.8-inch display and 2,300mAh battery, while retaining the same processor, RAM, storage, and stylus support as the larger model, according to the supplied related source. No supplied source reports an X6 Mini so far.

That leaves Boox with a launch-stage messaging challenge. The company has shown enough to make the Note X6 look faster, but not enough to prove how that speed changes the product.

After May 27, hands-on tests need to prove the 78% claim matters

The practical takeaway is simple: the Note X6 looks like a performance-led upgrade, but buyers should wait for real testing before treating the 78% figure as a reason to replace a current Note device.

For first-time buyers, the decision should come down to the full package: writing feel, display quality, software behavior, battery life, price, and whether the device launches in their market. The processor is now a serious part of that equation, but it is not the whole device.

The evidence that would confirm Boox’s thesis is clear: hands-on reports showing fewer stalls, faster system response, and no obvious sacrifice in battery behavior. The evidence that would weaken it is just as clear: strong chip specs paired with software friction, unclear global availability, or a final configuration that limits the processor’s advantage.

The Note X6 will not make E Ink feel like an iPad. But if Boox’s claim holds up after May 27, it could raise the baseline for what premium digital paper buyers expect from the hardware under the glass.

The Bottom Line

• Boox is positioning the Note X6 as a productivity device, not just a digital notebook.
• The 4nm Snapdragon 6690 and 2.9GHz clock speed suggest performance is becoming a premium E Ink selling point.
• Rivals may face pressure to compete on responsiveness as well as writing feel and display quality.
