HP OmniBook Ultra 14 Review

The HP 8EB4 laptop, configured with Intel’s Core Ultra X9 388H and integrated Intel Arc B390 graphics, lands in an awkward but useful middle ground. It is not a gaming laptop, and the benchmark data makes that plain within minutes. However, it is a surprisingly capable productivity machine with a strong PCMark 10 Extended score of 9,390, a fast enough CPU for office and creative bursts, and storage performance that keeps day-to-day work feeling responsive.

The catch is that its integrated graphics fall well behind even older gaming-laptop reference points in 3DMark, while the CPU runs hot under sustained multi-threaded load. If your workload revolves around spreadsheets, browser tabs, photo edits, and general business use, this HP looks competent. If you want modern gaming or ray tracing, you should keep shopping.

Editor’s Take

The HP 8EB4 is a good productivity laptop with respectable CPU muscle and disappointing graphics headroom, making it best for office work rather than gaming.

Pros

• Strong PCMark 10 result
• Excellent spreadsheet performance
• Respectable CPU scaling
• Responsive everyday storage
• Modern Intel platform features

Cons

• Weak gaming benchmark results
• Ray tracing is effectively unusable
• CPU runs hot under load
• SSD is only mid-pack
• Full retail configuration remains unclear

At a Glance

Configuration: What This HP 8EB4 Actually Packs

The tested HP 8EB4 configuration uses an Intel Core Ultra X9 388H processor paired with Intel Arc B390 integrated graphics, 64GB of memory, and a 1TB SSD. Windows 11 64-bit build 10.0.26200 handled the test environment, while Intel’s approved 32.0.101.8629 graphics driver powered the Arc GPU.

That is a healthy memory allotment for a thin-and-light or premium productivity notebook. You can comfortably run large spreadsheets, dozens of browser tabs, creative apps, and background collaboration tools without immediately running into memory pressure. The 1TB SSD is also the right capacity for a workhorse machine in 2026, even if its benchmark numbers do not place it among the fastest PCIe drives on the market.

What we do not have here is the full retail identity of the laptop, including display specs, battery capacity, port layout, or launch pricing. That limits how far I can go on value analysis. Still, the benchmark profile tells you a lot about the class of machine HP is aiming for.

Design and Daily Use: The Benchmarks Suggest a Work-First Machine

Without chassis measurements or display lab data, I cannot fairly judge the physical design. What I can say is that the component mix points to a premium productivity notebook rather than a gaming-first system. A 25W Core Ultra chip, integrated Arc graphics, 64GB of RAM, and enterprise-friendly security features like VBS and HVCI running by default all suggest a machine built for work, not for chasing frame rates.

That matters because the benchmark story stays consistent. This HP looks like the kind of laptop you would hand to someone living in Excel, Teams, Chrome, Photoshop, and a dozen browser-based dashboards. It does not look like the machine you would recommend to someone hoping to play new AAA games at high settings after work.

Performance Testing: Productivity Is the Real Story

The best result in this entire report is PCMark 10 Extended. HP’s system scored 9,390, which places it above the 2023 Gaming Laptop reference score of 8,996 and well above the Office Laptop reference of 5,385. It also landed in the 76th percentile overall. That is a strong showing for a 25W mobile platform.

The sub-scores make the case even more clearly. Productivity hit 20,583, spreadsheet work reached 25,853, and photo editing climbed to 26,457. Those are the numbers of a laptop that should feel quick in real office use. Web performance at 15,027 and writing at 16,388 reinforce the same point. If your day involves heavy multitasking, document work, browser-based research, and large spreadsheets, this HP should keep up comfortably.

Digital content creation also held up better than the gaming numbers would suggest. A score of 12,991 is not workstation-class, but it is solid for a machine leaning on integrated graphics. Intel’s Arc B390 helped accelerate photo editing, video conferencing, spreadsheets, and video editing through OpenCL, which explains why the system looks much healthier in PCMark than it does in pure graphics tests.

CPU Profile adds another useful layer. The Core Ultra X9 388H posted 6,968 at max threads, 5,872 at 16 threads, and 1,001 in the single-thread test. That is respectable scaling for a 25W mobile chip. However, the average CPU temperature hit 86 degrees Celsius during the CPU Profile run. That is the warning sign in an otherwise good CPU story. The processor has real punch, but it also runs hot when you lean on all cores for sustained work.

Graphics and Gaming Tests: This Is Not a Gaming Laptop

The 3DMark results are blunt. Night Raid, the lightest and most forgiving graphics test in the set, returned 29,536. That beats the Office Laptop reference score of 16,304, but it still sits far below the 2023 Gaming Laptop reference of 49,992. Wild Life told a similar story at 29,590, again below the Gaming Laptop reference of 40,215.

Once the workload gets heavier, the gap widens fast. Fire Strike scored 8,556, compared with a Gaming Laptop reference of 25,820. Time Spy dropped to 4,503, which is less than half the Gaming Laptop reference of 11,619 and only good for the 16th percentile. Those are not borderline gaming-laptop numbers. They are clear signs that the Arc B390 is best treated as a productivity helper with light gaming ability, not as a real gaming solution.

Ray tracing results close the case. Solar Bay landed at 23,407, Port Royal at 2,427, and Speed Way at 797. Port Royal placed above only 2% of results, while Speed Way effectively bottomed out the chart. If you were hoping this HP could handle modern ray-traced games in any practical way, the answer is no.

There is one small bright spot in the graphics section. Fire Strike’s Physics score reached 20,236, and Time Spy’s CPU score hit 8,753. Those numbers show the processor is doing its part. The bottleneck is the integrated GPU.

Storage Performance: Fast Enough, Not Fancy

The 1TB SSD turned in a 3DMark Storage Benchmark score of 2,016 and a PCMark 10 Full System Drive score of 2,130. Those are decent mid-range results. They should translate to quick boots, responsive app launches, and reasonable game load times.

The detailed storage breakdown supports that read. Move Game bandwidth reached 1,574.93 MB/s, while access times stayed low across the board, averaging 88 microseconds in 3DMark and 77 microseconds in PCMark 10. Those latency figures matter in daily use. They help the system feel snappy even when peak throughput is not class-leading.

Melody·October 25, 2019

What this drive does not do is challenge the best PCIe 4.0 or PCIe 5.0 notebook SSDs. Overall bandwidth of 341.34 MB/s in the 3DMark storage suite is fine, not exceptional. For office work, that is enough. For a premium flagship laptop, I would want more.

How the HP 8EB4 Compares

Is the HP 8EB4 Worth It?

The answer depends entirely on what you need. If you want a laptop for productivity, spreadsheets, browser-heavy work, and occasional creative tasks, the HP 8EB4 benchmark profile looks good. PCMark 10 Extended at 9,390 is the kind of result that suggests a fast, responsive daily machine. The 64GB of RAM only strengthens that case.

If you want a gaming laptop, this is the wrong tool. The Arc B390 falls well short of even older gaming-laptop reference scores in every meaningful 3DMark test, and the ray tracing numbers are especially poor. You can probably get away with lighter esports titles or older games at reduced settings, but that is not the same thing as buying a gaming-capable notebook.

The CPU thermals also deserve caution. An average of 86 degrees Celsius in CPU Profile is not catastrophic, but it does suggest the Core Ultra X9 388H is working hard inside this chassis under sustained load. I would want to see real-world thermal and acoustic testing before calling this machine a great fit for long rendering sessions.

For the right buyer, though, the HP 8EB4 makes sense. It looks like a work-first laptop with enough CPU and memory headroom to stay useful for years. Just do not confuse that with gaming strength.
