Review HP OmniBook 3 17-dp0451ng
HP OmniBook 3 17-dp0451ng
AMD Ryzen 5 40 · AMD Radeon 610M · 16GB LPDDR5 (soldered) · 512GB SSD · 17.3″ 1080p IPS (60Hz, 61.6% sRGB)
Budget 17.3‑inch office laptop with a misleadingly named "Ryzen 5 40" – actually a rebadged Ryzen 5 7520U based on ancient Zen 2 architecture. Features low power consumption, decent battery life, and a reasonable price, but suffers from outdated CPU/GPU performance, soldered RAM, poor SSD speed, and a mediocre 60% sRGB display. Priced around €550.
Display Panel
Panel model (tested): CMN1781 – 17.3″ 1920×1080 60 Hz IPS (matte, no touch).
| Spec | Value |
|---|---|
| Brightness | ~403 cd/m² peak, ~374 cd/m² average – above spec (300 cd/m²) |
| Colour Coverage | 61.6% sRGB, 41.3% DCI‑P3, 42.8% AdobeRGB – poor |
| Accuracy | ΔE 4.91 out‑of‑box; calibrates to 3.31 – cannot fix limited gamut |
| Response | 21 ms (black‑to‑white) – adequate for office |
| PWM | None – flicker‑free |
| Contrast | ~1679:1 (black 0.24 cd/m²) – solid |
| Refresh | 60 Hz – no high‑refresh options |
62% sRGB coverage – colours appear pale and washed out. Not suitable for photo editing or colour‑sensitive work. The matte surface is good for office environments (no reflections).
Keyboard & Touchpad
- Keyboard: No backlight – unconventional layout
- Unlit keyboard with strange layout – takes getting used to
- Touchpad: Rickety, sounds cheap when clicked
- Could be more stable
Input devices are mediocre – no backlight, unconventional layout, and a rickety touchpad. Not ideal for extended typing sessions.
Ports & Connectivity
- Left: 2× USB-C 3.1 Gen 2 (Power Delivery, DisplayPort), HDMI 2.1, audio jack
- Right: 2× USB-A 3.0
- No RJ‑45 Ethernet – dongle required
- No card reader – a notable omission
- Wi‑Fi 6 (MediaTek MT7920) – ~1,003 Mbit/s, slower than Wi‑Fi 7 rivals
- Webcam: Blurry and crumbly despite Full HD
Connectivity is basic – no Ethernet, no card reader, and Wi‑Fi 6 is outdated. The webcam quality is poor.
Serviceability & Upgradeability
Bottom cover: Five Phillips screws, but tight due to hooks.
| Component | Replaceable? | Difficulty | Notes |
|---|---|---|---|
| SSD | ✅ Yes | Low | Single M.2 2280 PCIe 4.0 – replaceable |
| RAM | ❌ No | – | Soldered LPDDR5 – not upgradeable |
| Wi‑Fi module | ❌ No | – | Soldered – not replaceable |
| Battery | ⚠️ Limited | Medium | Internal, replaceable with care |
| Display | ❌ No | High | Integrated into lid |
| CPU / GPU | ❌ No | – | Soldered BGA |
Limited upgradeability – only the SSD is replaceable. RAM and Wi‑Fi are soldered – choose 16 GB at purchase. No expansion options.
Storage (SSD)
- Tested Drive: Western Digital PC SN5000S SDEPMSJ-512G – 512 GB, M.2 2280 PCIe 4.0
- Sequential read: ~904 MB/s · write: ~888 MB/s – very slow for PCIe 4.0
- No throttling – stable at ~1,777 MB/s in DiskSpd loop (but low peak speed)
- Single slot – replacement only, no expansion
The SSD is extremely slow – sequential reads under 1,000 MB/s are unacceptable for a 2026 laptop. Resellers should strongly consider SSD upgrades to improve overall system responsiveness.
Memory (RAM)
- Configuration: 16 GB LPDDR5 (soldered)
- No SO‑DIMM slots – completely non‑upgradeable
- Memory latency: 130.8 ns – acceptable
RAM is soldered – 16 GB is the maximum. No upgrades possible. Customers must choose the 16 GB SKU at purchase.
Processor (CPU) – A Misleading Name
- Model: AMD Ryzen 5 40 – actually a rebadged Ryzen 5 7520U
- Architecture: Zen 2 (2020!) – outdated by 6 years
- Cores/Threads: 4c/8t @ 4.3 GHz
- TDP: 30 W PL2, 25 W PL1
- Cinebench R23 Multi: ~4,841 pts – ~60% slower than Ryzen AI 5 330
- Cinebench R23 Single: ~1,150 pts – ~58% slower than Ryzen AI 5 330
- Performance similar to 2022 Ryzen 5 7520U
The Ryzen 5 40 is a renamed 2022 processor – performance is 60‑90% slower than current AMD/Intel offerings. Only suitable for basic office work and web browsing – not for multitasking or demanding applications.
CPU Performance Comparison
| Processor | Cinebench R23 Multi | Performance vs. Ryzen 5 40 |
|---|---|---|
| Ryzen 5 40 (OmniBook 3) | 4,841 pts | Baseline |
| Ryzen 5 7520U (Acer Aspire 3) | 5,149 pts | ~6% faster |
| Ryzen AI 5 330 (IdeaPad Slim 5) | 7,840 pts | ~62% faster |
| Ryzen AI 5 430 (IdeaPad 5 2‑in‑1) | 8,130 pts | ~68% faster |
| Core Ultra 7 255U (OmniBook 5) | 9,049 pts | ~87% faster |
Graphics (GPU)
- Model: AMD Radeon 610M – 512 MB VRAM
- 3DMark Time Spy: ~493 pts – very weak
- Gaming: Cyberpunk 2077 (Ultra 1080p) ~3.1 fps – unplayable
- Radeon 820M is ~80% faster; Radeon 840M is ~170% faster
- Intel Graphics 4-Core is ~200% faster
- Only suitable for very old games (Dota 2 at 24 fps, GTA V at 5.8 fps)
The Radeon 610M is a relic – modern games are unplayable. Even casual gamers should look elsewhere. Only suitable for office work and video playback.
Battery
- Capacity: 41 Wh – small
- WiFi surfing (150 nits): ~10.5 hours – decent for the capacity
- Low power consumption compensates for small battery
- Internal battery – replaceable with moderate effort
Battery life is surprisingly decent – 10.5 hours of web browsing from a 41 Wh battery is impressive. The low power consumption is one of the few strengths of this platform.
Chassis & Build
- Materials: Plastic with metal‑like appearance
- Weight: 1.96 kg (4.32 lbs) – reasonable for 17.3″
- Dimensions: 397 × 256 × 16.4 mm – thin
- Lid can only be opened with two hands – poor hinge design
- Maximum opening angle ~130° – limited flexibility
- Stability leaves a lot to be desired – flexes in many places
- Stylish design – visually appealing despite plastic
Chassis stability is poor – the lid requires two hands to open, and the build quality feels cheap. The design is stylish, but not built to last.
Disassembly & Upgradeability Summary
| Component | Replaceable? | Difficulty | Notes |
|---|---|---|---|
| SSD | ✅ Yes | Low | M.2 2280 PCIe 4.0 – single slot |
| RAM | ❌ No | – | Soldered – choose at purchase |
| Wi‑Fi | ❌ No | – | Soldered – not replaceable |
| Battery | ⚠️ Yes | Medium | Internal, but replaceable |
| Fan / Heatsink | ⚠️ Clean only | Medium | Accessible, not user‑replaceable |
| Display | ❌ No | High | Integrated into lid |
| CPU / GPU | ❌ No | – | Soldered BGA |
Five Phillips screws give access to the internals – but the bottom panel is tight due to hooks. Only the SSD is user‑replaceable.
Procurement & Reseller Recommendations
Target Audience
Only for basic office use – web browsing, email, document editing. Not suitable for multimedia, gaming, or multitasking.
CPU
The Ryzen 5 40 is a renamed 2022 processor – performance is 60‑90% slower than current offerings. Recommend the OmniBook 5 (Core Ultra 7 255U) for better performance.
Display
61.6% sRGB coverage is poor – colours look washed out. The matte finish and good brightness make it usable for office work.
Storage
The SSD is extremely slow – under 1,000 MB/s reads. Offer SSD upgrades to significantly improve system responsiveness.
Value
At ~€550, the OmniBook 3 is competitively priced – but the performance is far behind similarly priced laptops with Ryzen AI 5 330 or Core Ultra 7 255U.
Connectivity
No Ethernet, no card reader, Wi‑Fi 6 only – basic connectivity. Recommend USB‑C hubs for customers who need more ports.
