AMD Ryzen 7 PRO 5875U
AMD Ryzen 7 PRO 5875U: A Balance of Power and Battery Life for Mobile Professionals
March 2025
Introduction
In the world of ultrabooks and business laptops, AMD's Ryzen PRO series processors have established themselves as reliable solutions for those who value performance without compromising on battery life. The Ryzen 7 PRO 5875U, released in 2022, remains relevant in 2025 thanks to its optimized architecture and energy efficiency. Let's explore who this chip is suitable for and what advantages it offers compared to contemporary competitors.
1. Architecture and Process Technology: Zen 3 in a Compact Package
Cores, Threads, and Cache
The processor is built on the Zen 3 architecture (codename Cezanne-U) and manufactured using TSMC's 7nm process. It combines 8 cores and 16 threads with a base clock speed of 1.9 GHz and a turbo boost of up to 4.5 GHz. The L3 cache size is 16 MB, which speeds up data processing in multithreaded tasks.
Integrated Graphics
The Radeon Graphics iGPU is based on the Vega architecture but has an improved clock speed (up to 2000 MHz) and 8 compute units. This allows for gaming at resolutions of 720p–1080p with low settings (e.g., CS:GO — 60–70 FPS, Fortnite — 40–50 FPS) and working with graphic editors like Photoshop or Lightroom.
Key Features of Zen 3
- 19% increase in IPC (instructions per clock) compared to Zen 2.
- Support for PCIe 3.0 (a platform limitation, but sufficient for NVMe SSDs and Wi-Fi 6).
- Security technologies: PRO features for data encryption (e.g., Microsoft Pluton).
2. TDP of 15W: Energy Efficiency Without Overheating
With a thermal design power (TDP) of 15W, the processor is ideal for thin laptops. Even under load, temperatures rarely exceed 70–75°C, thanks to:
- Precision Boost 2 — dynamic boosting of only active cores;
- Adaptive Power Management — automatic voltage reduction during idle periods.
In office tasks (browsing, Office), the chip consumes 5–8W, extending battery life to 10–12 hours in devices with a capacity of 60–70 Wh.
3. Performance: Real-World Scenario Tests
Office Work and Multimedia
- PCMark 10: 5500–5700 points. Running 20 tabs in Chrome + streaming video — no lag.
- Rendering in Premiere Pro: A 4K video takes 8–10 minutes (compared to 12–14 minutes for the Intel Core i7-1260P).
Gaming
- Shadow of the Tomb Raider (1080p, low settings): 32–35 FPS.
- Valorant (1080p, medium): 90–100 FPS.
Turbo Mode
During short bursts of load (e.g., opening a heavy Excel file), the frequency boosts to 4.5 GHz, but in sustained mode (long-term load), it stabilizes at 3.2–3.5 GHz due to TDP limitations.
4. Use Scenarios: Who is the Ryzen 7 PRO 5875U Suitable For?
- Professionals: Designers, programmers, analysts working with large spreadsheets or code.
- Students: Multitasking between lectures, rendering presentations.
- Travelers: Long battery life + capability for light gaming.
Example laptop for 2025: Lenovo ThinkPad T15 Gen 4 (16 GB RAM, 1 TB SSD, 15.6" FHD display) — price $950–1100.
5. Battery Life: How AMD Saves Power
- AMD PowerNow!: Automatic disabling of unused cores.
- Eco Mode in Manufacturer Software: Reduces performance by 15% to extend operating time by 2–3 hours.
- Support for LPDDR4X-4266 MHz: Low-voltage memory reduces overall system power consumption.
In tests:
- Video player (1080p, 50% brightness) — up to 14 hours;
- Mixed usage — 8–9 hours.
6. Comparison with Competitors
- Intel Core i7-1360P (12 cores, 16 threads): Higher single-core performance (Geekbench 6 ~1700), but inferior in multithreaded tasks (Geekbench 6 ~5200). Laptop prices: $1200–1400.
- Apple M3 (8-core): Leader in single-core (~2100), but limited compatibility with Windows applications. MacBook Air price: $1299.
- AMD Ryzen 7 7735U (Zen 3+): Insignificant performance gain (+5–7%), but higher cost ($100–150 more).
7. Pros and Cons
Strengths:
- Class-leading multithreaded performance.
- Good integrated graphics for casual gaming.
- Long battery life.
Weaknesses:
- PCIe 3.0 instead of PCIe 4.0 (relevant for high-speed SSDs).
- Lags behind the Apple M3 in single-core performance.
- Limited availability of laptops with this processor (more common in business lines).
8. Laptop Selection Recommendations
- Device Type: Ultrabook (e.g., HP EliteBook 845 G9) or 2-in-1 hybrid (Lenovo Yoga 7).
- What to Look For:
- Cooling: A dual-fan system to prevent throttling.
- Display: An IPS panel with 300 nits brightness for working in sunlight.
- Ports: USB-C with charging and DisplayPort support.
- Memory: At least 16 GB RAM for multitasking.
Tip: Don't overspend on a discrete GPU if you’re not planning to game — the iGPU Radeon handles basic tasks adequately.
9. Final Conclusion: Who is this Processor Suitable For?
The Ryzen 7 PRO 5875U is the ideal choice for:
- Mobile professionals needing power for heavy applications on the go.
- Budget users seeking a balance of price and performance (laptops starting from $800).
- Conservatives who prefer proven solutions with long support (drivers until 2027).
Key Benefits: Battery life of 10+ hours, stable performance without overheating, ready to handle workloads "out of the box."
Conclusion
Even in 2025, the Ryzen 7 PRO 5875U remains relevant thanks to its successful combination of Zen 3 architecture, low TDP, and affordable pricing. If you're not chasing maximum single-core performance and need a reliable laptop for work and study, this processor is worth considering.
