SteamOS vs Windows 11 Pro Comparison
Operating system
The Lenovo Legion Go S 8" 120Hz runs on SteamOS, giving you a console-focused interface designed specifically for handheld gaming navigation. In contrast, the ONERugged 6.5-inch Windows Rugged Handheld PC runs Windows 11 Pro, an enterprise-grade desktop environment built to support general desktop software, productivity applications, and business utilities. SteamOS centers your experience on a streamlined gaming ecosystem, while Windows 11 Pro gives you standard PC platform functions, background multitasking, and broad enterprise network tool support out of the box. Your software priorities determine which system serves your workflow better, leaving this category evenly matched.
Processor and graphics
The Lenovo Legion Go S 8" 120Hz features an AMD Ryzen Z1 Extreme processor running from 3.30 GHz up to 5.10 GHz, paired with AMD Radeon 780M graphics. This hardware gives you high-frequency processing for complex 3D rendering and fast frame generation. In comparison, the ONERugged 6.5-inch Windows Rugged Handheld PC uses a 2.8GHz Jasper Lake N5100 processor, and its graphics hardware is not specified in the data. The N5100 delivers stable performance for everyday mobile multitasking, but the Ryzen chip in the Lenovo provides significantly higher clock frequencies, giving the Lenovo handheld a decisive edge in processing power.
Screen resolution and refresh rate
The Lenovo Legion Go S 8" 120Hz provides an 8-inch screen with a 1920x1200 resolution and a fast 120Hz refresh rate. That higher refresh rate delivers smoother motion tracking and sharp visual output during quick transitions. Meanwhile, the ONERugged 6.5-inch Windows Rugged Handheld PC carries a 6.5-inch display at 720x1600 resolution with 400 nits of brightness, though its refresh rate is not listed in the specifications. The ONERugged screen offers solid brightness for outdoor environments, but the Lenovo device brings a larger viewing area, more pixel density across its panel, and high-refresh fluidity for dynamic content.
Memory and storage capacity
The Lenovo Legion Go S 8" 120Hz comes configured with 32GB of RAM and a 1TB SSD. This large memory allocation lets you run memory-heavy titles and multitask smoothly, while the 1TB drive holds substantial software libraries. The ONERugged 6.5-inch Windows Rugged Handheld PC includes 8GB of RAM paired with 128GB of ROM, along with TF card expansion supporting up to 512GB of extra space. While the ONERugged machine offers removable card expansion, the Lenovo handheld provides four times the system memory and eight times the built-in primary storage capacity without needing any extra memory cards.
Build and durability
The ONERugged 6.5-inch Windows Rugged Handheld PC features IP65 certification and MIL-STD-810H durability testing. It withstands accidental drops from up to 4 feet, direct water jets, extreme temperatures, and dust exposure, measuring 7.21 by 3.49 by 0.94 inches and weighing 11 ounces. In contrast, the Lenovo Legion Go S 8" 120Hz is styled in Nebula Nocturne, but its specifications do not list drop ratings, ingress protection numbers, or military-standard durability certifications. If you need a device that survives tough physical handling, job site debris, and outdoor environmental hazards, the ruggedized shell of the ONERugged takes the lead.
Which Handheld Device Should You Choose
Players prioritizing high frame rates and sharp visuals
You get an AMD Ryzen Z1 Extreme processor running up to 5.10 GHz, paired with an AMD Radeon 780M graphics chip. The 8-inch screen provides a 1920x1200 resolution and a 120Hz refresh rate. It also packs 32GB of RAM and a 1TB SSD for storing large game files directly on the device.
Users needing rugged drop resistance for outdoor work
You receive MIL-STD-810H and IP65 durability certifications that survive four-foot drops, moisture, dust, and water jets. The 6.5-inch 400-nit screen remains visible outdoors. An integrated Honeywell N4680 scanner reads 1D and 2D barcodes, while an 8MP rear camera and 5MP front camera capture operational photos in demanding environments.
Field workers needing swappable power and fast charging
You get a 4000mAh detachable battery that charges in 50 minutes with 45W fast charging. At 11 ounces and measuring 7.21 by 3.49 by 0.94 inches, it remains portable. You also get a 2.8GHz Jasper Lake N5100 processor, 8GB of RAM, and support for 512GB TF card expandable storage.
