Dell XPS 13 vs HP OmniBook 5 14: 8GB Aluminum or 34-Hour OLED? (2026)

Short answer: Choose the HP OmniBook 5 14 if battery life and an OLED screen matter most. Choose the Dell XPS 13 if you want an all-aluminum ultraportable and will pay for 16GB of memory. Every figure below comes from two PCMag reviews from 2026, and each one links to the page that reports it (PCMag XPS 13, PCMag OmniBook 5 14).

What this comparison covers

Both are 2026 Windows ultraportables. The XPS 13 is cheaper at base configuration, and the OmniBook 5 14 is the battery story. This page does not cover Apple laptops; see the MacBook Neo and MacBook Air comparison.

Scorecard

The price question

PCMag’s XPS 13 review says the $699.99 base model comes with an Intel Core 5 320, 8GB of memory and a 512GB SSD. The only memory upgrade is to 16GB, and PCMag says that upgrade alone takes the price to $899 (PCMag XPS 13 review). The same review notes an education discount of $100 that runs through November 2, 2026 (PCMag XPS 13 review).

The OmniBook 5 14 is priced differently. PCMag lists the “Next Gen AI” starting configuration at $879.99, with 16GB of memory and a 256GB SSD. The unit PCMag tested had 32GB of memory and a 1TB SSD, listed at $899.99, and PCMag says it was marked down to $699.99 when the review was published (PCMag OmniBook 5 14 review). Treat $699.99 as a publication-date figure, not a price you can count on.

So the gap depends on configuration, and the base models are the only fair price comparison.

Battery: the clearest gap

PCMag’s battery test plays a locally stored 720p video with display brightness at 50% and audio at 100%. Under that test, the OmniBook 5 14 lasted 34 hours and 48 minutes. PCMag says that outlasted the next-best laptops in its group by more than 14 hours (PCMag OmniBook 5 14 review). The XPS 13 lasted more than 20 hours in PCMag’s battery test (PCMag XPS 13 review).

The review says the OmniBook’s result was helped by its modest screen resolution and dim brightness at 50%. That makes the number a measurement of one test, not a promise for every workload (PCMag OmniBook 5 14 review).

Memory: the XPS 13’s main catch

PCMag names 8GB of memory as the first con of the XPS 13 (PCMag XPS 13 review). In its benchmark runs, the 8GB model could not finish several tests because of insufficient memory, including the Adobe Photoshop script. The program did launch, and PCMag says the problem shows up in some real Photoshop operations. The 16GB version completed those tests. PCMag also found the 16GB model a bit snappier overall in everyday use.

The OmniBook’s reviewed unit had 32GB, so the memory comparison is not like-for-like. Compare the configuration you would actually buy.

Screen, build and keyboard

The XPS 13 has an all-aluminum body, a 120Hz touch display and a backlit keyboard. PCMag found the screen on the dim side at 50% brightness (PCMag XPS 13 review). The OmniBook 5 14 has a 1920 x 1200 OLED panel at 60Hz, and PCMag says it is prone to glare in direct sunlight. Its keyboard deck is soft-touch plastic, which PCMag lists as a con (PCMag OmniBook 5 14 review).

Ports and connectivity

The XPS 13 has two USB-C ports, no headphone jack, and no HDMI or USB-A port. The OmniBook 5 14 has two USB-C ports, one USB-A port and a 3.5mm combo jack. PCMag says the OmniBook’s USB-C ports are not USB4 or Thunderbolt, and that they will do for most mainstream users (PCMag OmniBook 5 14 review).

Who each machine is for

• HP OmniBook 5 14: Students and travelers who go a full day away from an outlet, and who value an OLED screen over aluminum.
• Dell XPS 13: Buyers who want an all-aluminum, touch-enabled ultraportable and will pay for 16GB of memory. PCMag says the 8GB base model is the one to think twice about (PCMag XPS 13 review).

Pre-purchase steps

1. Memory. If the configuration you find is 8GB, PCMag’s tests suggest you budget for the 16GB upgrade (PCMag XPS 13 review).
2. Ports. Decide whether you need USB-A, HDMI or a headphone jack. The XPS 13 has none of these; the OmniBook has USB-A and a jack.
3. Processor type. The OmniBook uses a Snapdragon X Plus, which is an Arm chip. PCMag says the gaps in Arm-compatible software are specialized tools such as the Autodesk suite and parts of the Adobe Creative suite (PCMag OmniBook 5 14 review). Check your own apps first.
4. Price on the day. Use the official store on the day you buy. The reviews’ prices are snapshots.

Where this comparison stops

It does not measure the battery life you will get on your own workload, because PCMag’s test is a single video loop (OmniBook 5 14). It does not cover repairability, warranty or support, which the two reviews do not address. Each score comes from one reviewer, so read the full reviews if a single number decides the purchase.
