Performance & Benchmarks

• **Processor Performance:** 8th Gen Intel Core i5/i7 (Whiskey Lake) and 10th Gen Intel Core i5/i7 (Comet Lake) processors deliver strong performance for productivity tasks.
• **Benchmark Scores:**
  • PCMark 8: Achieves very decent scores, indicating good overall system performance for office work and everyday computing.
  • Geekbench 4: Shows very good multi-core and single-core scores for its class.
  • Internal Benchmarks: An i7-8565U with 16GB RAM model scored 83 in general benchmark tests, comparable to the HP Spectre x360 13.
• **Real-world Performance:** Handles video streaming, heavy web browsing with multiple tabs, word processing, and file sharing without significant slowdowns. CPU maintains 3GHz - 3.5GHz boost clock under extended workloads.
• **Graphics Performance:** Integrated Intel UHD Graphics 620 is suitable for basic 3D performance and low power usage, but not for demanding gaming or professional graphics applications.
• **Storage Performance:** PCIe NVMe SSDs provide fast read and write speeds.
• **Thermal Management:** Generally stays cool and quiet, even under load, though some users report minor heating around the display area during prolonged use.

The Lenovo ThinkPad X390 delivers solid performance for its target audience of mobile business professionals. The 8th and 10th generation Intel U-series processors provide sufficient power for multitasking and typical office applications, with benchmark results confirming its capability within the ultrabook category. The fast PCIe NVMe SSD significantly contributes to quick boot times and responsive application loading. However, the integrated Intel UHD Graphics 620 means the device is not suited for graphically intensive tasks, which is a common trade-off for ultraportable business laptops. While the RAM is soldered, opting for 16GB or 32GB at purchase ensures adequate memory for most professional workflows. Thermal management is effective, keeping the device relatively cool and quiet during typical use. Compared to similar devices, the X390 offers competitive performance, balancing power with portability and battery efficiency.

User Reviews & Feedback

User reviews consistently praise the ThinkPad X390 for its strong build quality, often highlighting the magnesium alloy chassis and MIL-STD 810G durability testing. The keyboard receives widespread acclaim for its excellent tactile feedback, long travel, and spill resistance, making it comfortable for extended typing sessions. The TrackPoint pointing device is also a favorite among ThinkPad enthusiasts. Users appreciate the generous selection of ports, including Thunderbolt 3 and USB-C charging, which enhances versatility. The bright, matte, and color-accurate FHD IPS display options are generally well-received, especially the anti-glare properties for outdoor use.

Common criticisms include the soldered RAM, which prevents future upgrades, and the inconvenient placement of the microSD card slot. Some users note that the Thunderbolt 3 port only supports two PCIe lanes, which can be a bottleneck for external GPUs. Battery life, while generally good, is sometimes cited as not lasting a full workday for all users, with some tests showing around 6-7 hours of continuous use, though other reports indicate up to 14-17 hours depending on configuration and usage. The base HD TN display option is widely considered subpar and not recommended. The lack of a higher-resolution panel (like QHD) compared to some competitors is also occasionally mentioned.

Vulnerabilities
