Short answer: The Galaxy Book4 Pro 360 is a polished, long-running 16-inch OLED convertible for everyday productivity, not a performance workstation or gaming laptop. HotHardware’s April 2024 tests found strong browser and general-use results, more than 15 hours in a controlled video-loop test, and capable integrated graphics. They also exposed weak sustained SSD writes, mixed CPU results and a fixed 16GB memory ceiling. Those trade-offs matter more than any single benchmark score.
The configuration behind these results
HotHardware tested a Moonstone Gray Galaxy Book4 Pro 360 with Intel’s Core Ultra 7 155H, 16GB of soldered LPDDR5-7467 memory and a 1TB PCIe 3.0 SSD. The 155H has six performance cores, eight efficiency cores and two low-power efficiency cores, with performance cores reaching up to 4.8GHz according to the review. Graphics come from an integrated eight-core Intel Arc GPU, not a discrete graphics card.
The chassis houses a 76Wh battery and a 16-inch, 2,880 × 1,800 AMOLED touchscreen with a dynamic 120Hz refresh rate. Its 360-degree hinge supports laptop, tent, stand and tablet positions, and the system supports S Pen input. The tested machine also had a 1080p webcam and a fingerprint reader built into the power button; the review did not report an IR camera for Windows Hello facial recognition or a physical webcam shutter. Ports include HDMI 2.1a, two Thunderbolt 4 ports, USB 3.2 Gen 2, microSD and a headphone/microphone connection. HotHardware’s review overview has the full design and configuration details.
This is one review configuration, not a guarantee about every regional SKU. Memory is soldered and cannot be expanded. The review did not establish whether the installed SSD is replaceable, so do not assume an internal storage upgrade is available. Check the exact model number and package in your market, including whether an S Pen is included.

What the benchmark page tells you
The review’s results combine storage tests (IOMeter and ATTO), browser testing (Speedometer 2.0), processor tests (Cinebench R23 and 2024, Geekbench 5 and 6), PCMark 10, AI testing with UL Procyon, and graphics tests including 3DMark Night Raid and Fire Strike Extreme. Each test measures a slice of performance; none by itself predicts how every application will behave. The software, power limits, cooling and competing systems also differ, so comparisons across laptops are useful context rather than controlled head-to-head proof.
One especially useful distinction is burst versus sustained speed. A laptop can respond quickly to a short task yet slow down during a long export or a large file write. The Book4 Pro 360’s results show that distinction in both its SSD and its processor.
SSD: responsive in normal use, weak at prolonged writes
The tested 1TB Samsung system-integrator drive, model MZVL41T0HBLB-00B, initially reached roughly 3,000MB/s in testing. That burst did not last: HotHardware’s IOMeter runs averaged about 640MB/s for writes with the drive 90% full and about 664MB/s with it 50% full. The fast phase lasted seconds in one test and about a minute in another. After 500 seconds of sustained writing, the drive reached about 60°C. ATTO also showed unremarkable peak sequential performance that did not saturate a PCIe 3.0 M.2 interface. See the benchmark-page storage results.

Pick the symptom - the matching free tool is one click away.
For browsing, office documents, starting applications and ordinary transfers, the drive should be serviceable. The limitation is more likely to appear when repeatedly copying large files, creating backups, installing large games or using the drive as a scratch disk for media work. The measured result belongs to the review sample; another retail configuration or replacement drive may behave differently. The lower sustained speed also has a possible upside in a thin convertible: the test found modest drive heat despite its sustained-write weakness.
Everyday productivity is a better story than CPU charts alone
HotHardware recorded a Speedometer 2.0 score of 351 and described the laptop as highly competitive among lower-power systems in that browser benchmark. PCMark 10 also placed it well in mainstream productivity and digital-content-creation scenarios. That fits a laptop intended for browser-heavy work, Microsoft Office, communications, streaming and ordinary multitasking. It is also suitable for light photo work and occasional content creation, provided expectations remain reasonable.

These results help explain why mixed processor comparisons do not automatically mean the machine feels sluggish. General work often depends on brief bursts, browser responsiveness, memory and storage behavior rather than hours of continuous all-core rendering. For long renders, large code builds, professional compilation or other sustained CPU-heavy jobs, the Book4 is not the most compelling choice in this class.
Core Ultra 7 155H: competent, but not a consistent generational leap
The CPU results were mixed. In Cinebench R23, the Book4 Pro 360 trailed a previous-generation Core i7-1360P laptop in the review’s comparison. In Cinebench 2024 and Geekbench, it also fell behind the Apple M2 Pro and the Snapdragon X Elite comparison system used by HotHardware. That Snapdragon system was a prototype tested before commercial X Elite laptops were available at the time, so it is not a like-for-like retail comparison.
The Tool Desk
Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →The fair conclusion is not that the Core Ultra 7 155H is universally slow. It is a capable mobile processor, but its advantage over earlier generations was inconsistent in these tests. The review’s results are consistent with a design that balances performance with power, temperatures and noise rather than maximizing sustained multicore output; that is an interpretation of the measurements, not a claim about Samsung’s stated design intent. The 155H also brings an NPU and stronger integrated graphics than older Intel integrated-GPU platforms. An NPU’s presence does not, by itself, mean that a particular AI application will use it or run faster: practical benefits depend on software support and whether work is accelerated by the NPU, GPU or CPU.
Integrated Arc graphics: a step up, not a gaming GPU
The eight-core Arc graphics are a meaningful improvement over the Iris Xe graphics found in many 13th-generation Intel systems. In 3DMark Night Raid, the Book4 roughly matched Radeon 680M-class integrated graphics, but fell behind Radeon 780M and the higher-powered Core Ultra 7 165H configuration in the comparison. It came closer to the MSI Prestige 16 AI Evo in the older Fire Strike Extreme test, but HotHardware noted that Fire Strike is a shorter, older test that includes CPU work. It should not be treated as a universal forecast of game performance. The review’s graphics charts and caveats are here.
With no discrete GPU, this is best regarded as a machine for esports, indie games, older titles and some less demanding games—not modern AAA gaming at the display’s full 2,880 × 1,800 resolution. Expect to lower resolution to 1080p or below, select low or medium graphics settings and use upscaling where a game supports it. Results will vary with the title, drivers, thermal conditions and Samsung’s selected performance profile. A synthetic graphics score is not a promise of a particular frame rate.

Four Samsung performance profiles
The review identifies four system profiles: High Performance, Optimized (the default), Quiet and Silent. They coordinate performance and cooling behavior rather than simply acting as interchangeable Windows power labels. High Performance raised performance modestly in the review; Quiet reduced it to reduce fan noise, and Silent cut it further and could eliminate fan noise in the tested workloads.

The reviewed unit had a dedicated function-row control, but software labels and menu locations can vary with updates and region. Check the current Samsung settings on the specific laptop rather than relying on a guessed shortcut or menu path.
Battery, heat and fan noise
HotHardware measured more than 15 hours in PCMark 10’s video-loop test, with Wi-Fi enabled and brightness set close to 115 lux. That is a strong controlled result for a large OLED convertible, but it is not a guarantee of 15 hours of work: video playback is a different workload from video meetings, heavy multitasking or CPU/GPU-intensive editing. High OLED brightness, a 120Hz refresh setting, background activity, external displays and performance mode can all change runtime. The 76Wh battery is not upgradeable, according to the review.
In the review’s Cinebench R23 run on the default Optimized profile, fan noise reached about 44dB. The processor briefly peaked near 98°C while package power rose to roughly 68W, then settled near its nominal 28W level; temperatures later fell into the low 80°C range. A short boost to a high temperature is not, by itself, evidence of a fault. Under lighter browsing and video playback, the fan was reported to remain unobtrusive. The laptop can be quiet in ordinary use, but it is not silent during demanding sustained work. HotHardware’s battery and thermal test details include the conditions behind these figures.

The 16-inch AMOLED screen is the clearest reason to consider this model. Its high resolution and smooth refresh capability suit spreadsheets, split-screen work, media and pen input. HotHardware reported 120% DCI-P3 color coverage/volume; preserve that as the review’s reported measurement rather than treating it as a universal guarantee of color accuracy. The review unit reportedly defaulted to 60Hz despite supporting dynamic 120Hz, so check the display setting if smoother motion matters—and bear in mind that refresh rate and brightness can affect battery use.

The aluminum body, large glass touchpad, near-full-size keyboard with numeric keypad, touchscreen and 360-degree hinge make it adaptable at a desk or for handwriting and sketching. The 16-inch format is also a real compromise: it gives you room to work, but feels large and awkward compared with a 13- or 14-inch device when held as a tablet. The numeric keypad means the main keyboard layout may feel more compressed than a tenkeyless keyboard. OLED long-term burn-in was not tested in the review, so its testing cannot establish panel longevity.
Two Thunderbolt 4 ports and HDMI provide useful display connectivity, but a port may be occupied by charging in a desk setup. A USB-C or Thunderbolt dock with charging passthrough can make a multi-monitor desk arrangement more practical. Check the exact dock and display configuration for compatibility rather than assuming every combination will work from a benchmark review.
Who should consider it?
The Book4 Pro 360 suits someone who prioritizes a premium large OLED, pen-capable convertible design, strong everyday responsiveness and long light-use battery life. It is a plausible fit for office work, study, note-taking, presentations, streaming and casual gaming. Samsung phone owners may also value ecosystem features, though the review’s performance results do not measure how useful those features will be to a particular buyer.
Look elsewhere if you need 32GB or more memory, run virtual machines or large development environments, regularly create large media projects, depend on sustained fast writes, or want modern games at high settings. The soldered 16GB ceiling deserves particular attention for long-term ownership: browsers, creative software, development tools and local AI workloads can make that limit more noticeable over time. That is a forward-looking buying judgment, not a benchmark result from the 2024 review.

HotHardware published its review on April 5, 2024. It cited a $1,899 starting MSRP and a $1,499 sale price at that time; neither is a current 2026 price. Samsung’s former US Galaxy Book4 Pro 360 product URL now redirects to the Galaxy Book5 Pro 360, a signal that the Book4 is an older generation rather than Samsung’s current flagship 2-in-1 listing. A redirect does not prove every retailer has stopped selling the Book4.
If considering a remaining Book4 listing, compare its actual price and exact configuration with newer Samsung models and current Windows convertibles. Check warranty and return terms, memory capacity, included pen, battery condition if used, and the seller’s precise model number. The Book4 is most persuasive at a price that reflects its age and limits—not at a premium close to a newer convertible or a system with more memory or discrete graphics.
All measured results above are from HotHardware’s review and apply to its tested configuration and methods; they are not guarantees for every unit or workload.
