HP OmniBook 5 and the Lenovo ThinkPad E16 Gen 3 (2025) are both 16-inch laptops running Intel Core Ultra chips, priced at roughly 25-35 million VND, but side by side they serve very different users. The OmniBook 5 has a touchscreen and the largest battery in this segment at 59 Wh, while the E16 Gen 3 uses the Meteor Lake-H architecture, which sustains multi-core performance better under long loads, and supports up to 64GB of RAM. In this article, Hung Phat compares the two machines use case by use case so you can pick the right one from the start.
CPU Performance and Processing Power Compared
In real-world benchmarks, the Core Ultra 5 225U in the HP OmniBook 5 scores 1,731 single-core and 11,843 multi-core in Cinebench R23. The Core Ultra 5 135H in the ThinkPad E16 Gen 3 posts 1,700 single-core and 11,875 multi-core in R23, nearly identical in multi-core, but the 135H has a clearer advantage in sustained workloads thanks to its 28W TDP (PL2 up to 64-115W depending on the OEM configuration), versus just a 15W base for the 225U (PL2 57W). In Geekbench 6 single-core, the 225U scores 2,372 and the 135H scores 2,278, so the 225U edges ahead in single-threaded tasks thanks to the newer Arrow Lake-U architecture.

On the AI front, both have an integrated NPU, but HP lists the 225U at 12 TOPS, enough for light AI tasks on Windows such as background blur and automatic captions. The 135H, a Meteor Lake part, also has an NPU, but Lenovo has not officially confirmed the TOPS figure for this specific SKU, so Hung Phat is not filling in a number to avoid getting it wrong. The 225U's integrated GPU is an Arc with 4 Xe-cores, while the 135H has an Arc with 7 Xe-cores (Meteor Lake), which means that for light graphics work such as photo editing and exporting 1080p video, the 135H is a notch smoother in practice.
If you use Office, join online meetings, or do basic web development, both handle it well, and you will not notice much difference day to day. Under heavier multitasking such as compiling code, exporting short videos, or running local AI models, the 135H in the E16 Gen 3 holds steadier performance thanks to its higher TDP and thicker cooling system. The real downside of the 225U: a thin chassis means limited cooling, so throttling kicks in sooner under sustained high load beyond 15 minutes.
Display, Design, and Hardware Upgrades
The biggest difference in everyday experience is the display. The touch version of the HP OmniBook 5 has a 16-inch WUXGA 1920x1200 panel in a 16:10 ratio with multitouch support, handy for dragging and tapping directly on the screen. The ThinkPad E16 Gen 3 also uses a 16:10 WUXGA anti-glare panel at 300 nits, but without touch. On color, the E16 Gen 3 is rated at 45% NTSC, which is fairly low and not suited to serious photo editing. The non-touch OmniBook 5 reaches 62.5% sRGB; the exact figure for the touch version is not confirmed, and Hung Phat will update this once real-unit measurements are available.
In terms of physical design, the OmniBook 5 uses an aluminum lid and palmrest with a plastic bottom, and is thin and light at about 1.63-1.8 kg depending on configuration. The ThinkPad E16 Gen 3 weighs about 1.63 kg, has a full aluminum body, and is MIL-STD-810H certified, a clear advantage if you move around a lot, take your laptop to job sites, or travel for work often. The OmniBook 5 has no MIL-STD certification and suits office use or light travel.
Upgradeability is where the two differ most. The OmniBook 5's RAM is soldered to the motherboard, so if you buy 16GB, you are stuck with 16GB and cannot add more. The E16 Gen 3 has 2 DDR5 5600MHz SO-DIMM slots and can go up to 64GB later. For SSDs, the E16 Gen 3 has 2 M.2 slots (one 2242 and one 2280), while the OmniBook 5 has no confirmed second slot. For IT professionals, technicians, or anyone using a mobile workstation who needs to expand gradually over time, the E16 Gen 3 is far more flexible.
Battery, Price, and When to Choose the HP OmniBook 5
Battery is where the OmniBook 5 has a clear edge: 59 Wh versus 48 Wh for the E16 Gen 3. In typical office use, the OmniBook 5 lasts 6-9 hours, while the E16 Gen 3 lasts only 4-6 hours. If you often work from coffee shops or spend all day at conferences without plugging in, that is a significant gap. The OmniBook 5 also supports fast charging to 50% in 30 minutes over USB-C 65W. The E16 Gen 3's exact fast-charging spec has not been confirmed for the SKU on sale.
For connectivity, the OmniBook 5 has 2 USB-C 10Gbps ports (PD 3.1, DP 1.4a), 1 USB-A 10Gbps, 1 USB-A 5Gbps, and HDMI 2.1, but no RJ-45. The E16 Gen 3 comes with RJ-45 Ethernet, HDMI 2.1, USB-C 20Gbps, and 2 USB-A ports, leaning toward fixed office setups. If you need a stable wired network connection or want to connect displays through several ports at once, the E16 Gen 3 has the clear advantage.
The table above summarizes the specs of both machines so you can compare them easily. Base your decision on your actual needs rather than a price gap of a few million VND. The HP OmniBook 5 is currently in stock at Hung Phat with official manufacturer warranty, and Hung Phat can help you choose the right configuration for your budget. If you are in Ho Chi Minh City, you can stop by in person to try the machine or order online for home delivery.
If you use your laptop mostly at home or in the office and want a touchscreen, flexible handling, and all-day battery life, the HP OmniBook 5 is the better fit. If you need multi-core performance that holds up under long loads, RAM you can expand later, or you travel often and want a sturdier machine with MIL-STD certification, the ThinkPad E16 Gen 3 justifies its slightly higher price. If you are still unsure, Hung Phat is ready to give more advice based on your specific needs.

Frequently Asked Questions (FAQ)
How do the two machines differ in real-world performance for daily work?
For typical office tasks such as Office apps, browsing, and online meetings, both run smoothly and you will hardly notice a difference. Under heavier multitasking such as long code compiles, video exports, or running local AI models, the Core Ultra 5 135H in the ThinkPad E16 Gen 3 maintains better performance thanks to its 28W TDP (PL2 up to 64-115W), while the 225U in the OmniBook 5 is capped at a 57W PL2 and has thinner cooling. Multi-core Cinebench R23 scores are nearly equal (11,843 versus 11,875), but in 15-30 minute sustained tests, the E16 Gen 3 throttles less because of its thicker cooling system.
Battery and temperatures: which machine lasts longer through the day?
The OmniBook 5 clearly wins on battery: 59 Wh versus 48 Wh for the ThinkPad E16 Gen 3, which works out to 6-9 hours of real office use versus 4-6 hours. Fast charging takes the OmniBook 5 to 50% in just 30 minutes via a USB-C 65W adapter, very handy if you only have a 30-minute break between sessions. On heat, the OmniBook 5 is thin, so under sustained high load the body will run warmer than the ThinkPad E16 Gen 3; the traditional ThinkPad line still manages heat better in prolonged workloads. For a full day on the move without plugging in, the OmniBook 5 has the clear advantage.
Is the price gap worth it to step up to the ThinkPad E16 Gen 3?
The ThinkPad E16 Gen 3 has a market reference price of 25-35 million VND, while the OmniBook 5 sits at 26-31 million VND, with the gap depending on configuration. For that difference you get RAM expandable up to 64GB later (the OmniBook 5's soldered RAM cannot be upgraded), 2 M.2 SSD slots, MIL-STD-810H certification, and an RJ-45 port. If you plan to use the machine for 3-4 years and expect to upgrade RAM after 1-2 years, moving up to the E16 Gen 3 is worth it. If you just need a light office machine with a touchscreen and good battery life, that extra money does not buy you real value.
Which machine suits which needs?
The OmniBook 5 suits office workers, teachers, sales staff, or content creators who use lightweight apps and want a touchscreen for flexible input, all-day battery life, and a machine that is not too heavy. The ThinkPad E16 Gen 3 is a better fit for mobile workstations, IT technicians, programmers who will need more RAM later, or anyone who travels often and wants a machine that holds up better over time. The HP OmniBook 5 is currently in stock at Hung Phat, and you can get in touch for advice on choosing the right configuration for your actual budget.
