Omnica A5 15.6" UL156-A Silver 2025

The Omnica A5 UL156-A is a $376 Windows 11 Pro laptop with a 1TB SSD and 16GB of RAM, but its ancient Core i5 7Y54 CPU is one of the slowest we've tracked. It's fine for basic office work and web browsing, but anything more demanding will frustrate you. The FHD IPS screen and backlit keyboard are nice, but the 38Wh battery and outdated Wi-Fi 5 are drawbacks. Buy it only if you need a cheap, big-screen typewriter and can live with the lag.

Let's talk about that Core i5 7Y54. In our database, this CPU sits at the 3rd percentile for laptops. That's not a typo. It's one of the slowest processors we've tracked in a modern laptop. The 7Y54 is a dual-core chip with a 4.5W TDP, which means it's designed to sip power and generate almost no heat. The trade-off is that it throttles aggressively under sustained load. The 3.2GHz boost clock sounds okay, but it can only hit that for a split second before dropping back down. For basic tasks like writing in Word or checking email, it's fine. But open a complex spreadsheet or try to run a video call while multitasking, and you'll feel the lag. The 16GB of DDR3 RAM helps a bit, but it's older, slower memory, and it can't make up for the CPU bottleneck.

The storage situation is actually the bright spot here. A 1TB SSD puts this machine at the 67th percentile for storage, which is solid for the price. You're getting a lot of space, and it's an SSD, so boot times and app launches will feel snappy compared to a spinning hard drive. The GPU, an Intel HD Graphics 615, ranks at the 90th percentile in our database, which sounds impressive until you realize that's a percentile ranking against other integrated graphics from the same era. It's still an integrated GPU from 2016. It can handle video playback and basic 2D tasks, but gaming is a non-starter. Our gaming score for this machine is 18.2 out of 100, which is one of the worst we've seen. Don't buy this for games, period.

Stack this against the Lenovo ThinkPad E14 Gen 7 and the difference is night and day. The ThinkPad has a modern processor, better build quality, and a keyboard that's legendary. It costs more, but you're paying for a machine that will still feel responsive in three years. The Omnica A5 feels like a budget stopgap. The HP OmniBook X Flip is another competitor, and while it's a convertible with a touchscreen, it's also in a completely different price bracket. If you can stretch your budget, any of these alternatives will give you a much better experience.

The Apple MacBook Pro M3 Pro is in a different universe entirely. It's not even a fair comparison. The MacBook's M3 Pro chip is one of the fastest mobile processors we've ever tested, and the Omnica's 7Y54 is one of the slowest. The only thing they share is a screen size. If you're cross-shopping these two, you need to seriously reconsider your priorities. The ASUS Zenbook UX3405CA and Samsung Galaxy Book5 Pro are also far more capable machines, but they cost three to four times as much. The Omnica A5 exists for people who absolutely cannot spend more than $400 and need a Windows machine right now.

At $376 USD, the Omnica A5 is priced like a budget Chromebook but ships with Windows 11 Pro and a full Office suite. That's genuinely compelling if you just need a machine for documents, email, and light web use. The 1TB SSD alone would cost you a decent chunk of that price if you bought it separately. And 16GB of RAM means you can keep a reasonable number of tabs open without the system grinding to a halt. The problem is that the CPU is so weak that the RAM and storage can't fully shine. It's like putting a Ferrari engine in a go-kart with a lawnmower transmission. The parts are there, but the whole thing is held back by the weakest link.

Compared to other laptops in this price range, you're making a trade-off. A used ThinkPad or a budget HP with a newer Ryzen 3 or Core i3 will run circles around this thing in CPU performance, but you'll likely get less storage and maybe less RAM. If your workload is genuinely light, the Omnica A5 is a decent deal. If you ever need to do anything more demanding than word processing and web browsing, you'll outgrow it fast.

The Omnica A5 UL156-A is one of those machines that makes you do a double take. On paper, it's got a 15.6 inch FHD IPS display, 16GB of RAM, a 1TB SSD, and Windows 11 Pro with an Office suite pre-loaded. That's a spec sheet that sounds like a mid-range productivity workhorse. But then you look at the processor, an Intel Core i5 7Y54 from 2016, and you realize this thing is a bit of a time capsule. It's a fanless, ultra-low-power chip designed for thin tablets, not a 15.6 inch laptop. The whole package is a strange mix of modern storage and memory paired with a CPU that was already slow when it launched.

Who is this for? Honestly, it's for someone who needs a basic Windows machine for light office work, email, and web browsing, and who values a big screen and a full keyboard over raw speed. The 180 degree hinge and backlit keyboard suggest it's aimed at students or office workers who need to share their screen or type in dimly lit rooms. The 1.6kg weight is fine for a 15.6 inch laptop, so it won't break your back in a backpack. But calling it a "Gaming Laptop" in the retailer notes is a stretch that borders on comedy. The integrated Intel HD Graphics 615 can barely handle Minesweeper at high settings.

The interesting thing here is the price. At $376 USD, it's cheap. Really cheap for a laptop with 16GB of RAM and a 1TB SSD. But that low price comes with some serious compromises, and the biggest one is the CPU. We'll dig into the numbers below, but the short version is that this is a machine for patient people. If you're the type who opens a dozen Chrome tabs and expects instant response, you're going to be frustrated. If you need a cheap, portable typewriter with a nice screen, it might just work.

If you do any kind of demanding work, skip this. Video editors, programmers, data analysts, and anyone who runs virtual machines or heavy multitasking will find the Core i5 7Y54 unbearable. It's a dual-core chip from 2016 with a 4.5W TDP, and it shows. Even basic tasks like running a video call while sharing your screen can cause stutters. If you need a machine for work that pays the bills, spend a bit more on something with a modern Ryzen 3 or Core i3. A used ThinkPad or a budget HP will serve you far better.

Gamers should also look elsewhere. The Intel HD Graphics 615 is not a gaming GPU, and our gaming score of 18.2 out of 100 reflects that. If you want to play anything more demanding than solitaire, you'll need a laptop with a dedicated GPU or at least a modern AMD APU. And if you need all-day battery life, the 38Wh cell here won't cut it. Look for something with a 50Wh or larger battery and a more efficient modern processor.

If you need a cheap laptop for writing, email, and light web browsing, and you can live with a sluggish CPU, the Omnica A5 is a reasonable buy at $376. The 1TB SSD and 16GB of RAM are genuinely useful, and the FHD IPS screen is easy on the eyes. The backlit keyboard is a nice bonus for late-night work. Just know that this is a machine for patient people. It will get the job done, but it won't do it quickly.

For students or office workers who need to run multiple applications at once, do video calls, or work with large spreadsheets, we'd steer you toward something with a newer processor. A used ThinkPad or a budget HP with a Ryzen 3 or Core i3 will be a much better long-term investment. The Omnica A5 is a stopgap, not a daily driver for demanding work. And for the love of all that is holy, don't buy it for gaming.
