Overview

The LG Gram 16 2-in-1 (16T90Q) pairs a 2560×1600 IPS touchscreen — calibrated to 99% DCI-P3 coverage — with Intel's 12th Gen i7-1260P, 32GB of LPDDR5-5200, and a 2TB PCIe Gen 4 NVMe SSD in a chassis that weighs 3.26 pounds. To put those specs in context: the 16:10 display ratio gives 11% more vertical screen real estate than a 16:9 panel of the same diagonal, the LPDDR5 memory bus runs nearly 70% faster than LPDDR4X found in most competitors, and the PCIe 4 SSD makes file I/O fast enough that the storage subsystem rarely becomes a bottleneck even during large media imports. The 72 Wh battery — unusually large for this weight class — is what enables the 12+ hour real-world endurance LG claims.

This machine is built for creative professionals, consultants, and power users who genuinely need a 16-inch canvas but refuse to check a bag. The 360-degree hinge adds presentation and annotation flexibility that a traditional clamshell can't offer, while the Thunderbolt 4 port future-proofs the machine for external GPU enclosures or high-bandwidth docks as workloads evolve. WiFi 6E keeps connectivity fast in congested office environments. The trade-off is integrated-only graphics — the Iris Xe handles photo editing, 4K playback, and light GPU-accelerated tasks, but it is not a machine for sustained 3D rendering or high-refresh gaming. Within those boundaries, the Gram 16 is among the most technically complete thin-and-light convertibles in its size class.

Pros & Cons

👍 Pros

  • The 99% DCI-P3 color gamut on the 2560×1600 IPS touch panel makes color-critical creative work accurate without an external display.
  • 32GB of soldered LPDDR5 at 5200 MHz delivers bandwidth headroom that most thin-and-lights at this weight class simply can't match.
  • At 3.26 pounds for a 16-inch convertible, the MIL-SPEC 810H chassis achieves a strength-to-weight ratio that competing 16" 2-in-1s rarely approach.
  • The 72 Wh battery with up to 19.5 hours of video playback means the machine genuinely survives full travel days without hunting for an outlet.
  • Thunderbolt 4 support provides 40 Gbps bandwidth for external GPUs, docks, or 8K display daisy-chaining from a single port.

👎 Cons

  • Iris Xe integrated graphics handle light creative and casual gaming adequately but hit a hard ceiling on GPU-accelerated workloads like 3D rendering or high-FPS gaming at the native 2560×1600 resolution.
  • The 16-inch form factor makes tablet mode physically awkward for extended handheld use — this is a laptop that converts, not a tablet that docks.
  • RAM is soldered at 32GB with no upgrade path; buyers who anticipate needing more memory down the road have no recourse without replacing the machine.
  • The 16:10 aspect ratio panel, while excellent for productivity, means some streaming content displays with black bars rather than filling the screen.
  • At this price tier, the webcam resolution (FHD) is adequate but the fixed-focus optics lag behind competition that includes face-tracking or higher-quality sensors.

Frequently Asked Questions

The i7-1260P is a hybrid-architecture chip with 4 Performance cores and 8 Efficiency cores, enabling it to sprint through intensive tasks like video exports while dialing back on lighter workloads to preserve the 72 Wh battery. Compared to 11th Gen chips in earlier Gram models, expect roughly 30–40% better multi-core throughput and significantly improved Iris Xe integrated graphics — enough for light creative work and 4K video playback without a discrete GPU.
It is soldered to the motherboard at 5200 MHz, which is the trade-off for the ultra-thin form factor. You cannot upgrade it post-purchase. The upside is that 5200 MHz LPDDR5 has substantially higher bandwidth than the LPDDR4X found in most competing thin-and-lights, which reduces latency on large dataset operations and memory-intensive creative apps.
PCIe 4 doubles the maximum bandwidth ceiling versus PCIe 3 — sequential reads can reach 5,000–7,000 MB/s on top-tier drives, versus ~3,500 MB/s on PCIe 3. For daily use this translates to near-instant app launches, fast large-file transfers, and snappier cold boots. At 2TB, you have enough headroom to store full project libraries, virtual machines, and OS images without juggling external drives.
Yes — LG engineers the Gram hinge for consistent torque across its full rotation arc. In tablet mode the 16-inch panel does add noticeable hand fatigue over extended sessions due to the form factor's size; this is a deliberate trade-off of a 16" 2-in-1 versus a smaller tablet. For desk-based tent or presentation mode, the hinge holds angle well without drift.
WiFi 6E adds the 6 GHz band, which is less congested than 2.4 GHz or 5 GHz in dense environments (offices, apartments). If your router supports 6 GHz, you'll see lower latency and more stable throughput — particularly relevant for large cloud sync operations or video calls. If your router is WiFi 5 or older, the chip falls back gracefully with no performance penalty.
