AMD Ryzen 7 5825U: A Balance of Power and Efficiency for Mobile Devices
March 2025
Modern laptops demand high performance from processors, as well as energy efficiency. The AMD Ryzen 7 5825U, released in 2023, remains a relevant solution for ultrabooks and business devices even in 2025. Let's explore who this chip is suitable for, how it handles tasks, and what nuances to pay attention to when choosing.
Architecture and Process Technology: Zen 3 in a Compact Package
The AMD Ryzen 7 5825U (codename Barcelo) is built on the updated Zen 3 architecture and manufactured using the TSMC 7nm FinFET process. This ensures high transistor density and optimized power consumption.
- Cores and Threads: 8 cores and 16 threads. Base frequency — 2.0 GHz, maximum in turbo mode — 4.5 GHz.
- Cache: 16 MB L3 cache, which speeds up data processing in multi-threaded scenarios.
- Integrated Graphics: Radeon Graphics with 8 compute units (512 stream processors) and a frequency of up to 2.0 GHz. Support for DisplayPort 1.4, HDMI 2.1, and FreeSync technologies for smooth visuals.
The Zen 3 architecture has improved compared to Zen 2: higher IPC (instructions per cycle) and a revamped cache access scheme. This is especially noticeable in latency-sensitive applications — for example, in gaming or video processing.
TDP 15W: Energy Efficiency Without Compromise
The TDP (Thermal Design Power) of 15W indicates that the processor is designed for thin and light laptops. However, thanks to dynamic frequency (Precision Boost 2) and voltage management, the chip adapts to workloads:
- In idle mode, the frequency drops to 1.2 GHz, with consumption down to 5-7W.
- Under peak load (e.g., rendering), power can temporarily reach 25W if the cooling system allows it.
To reduce power consumption, the following are employed:
- AMD PowerNow! — automatic switching between performance modes.
- Hybrid core design: some cores can be disabled under low load.
Performance: From Office Applications to Casual Gaming
Office Tasks and Multimedia
- Web browsing, documents: The Ryzen 7 5825U handles dozens of Chrome tabs and simultaneous work in Excel without slowdowns.
- Photo Editors: Exporting 100 RAW files in Lightroom takes ~3 minutes.
- Video Editing: Rendering a 10-minute 1080p video in DaVinci Resolve takes about 8 minutes.
Gaming
Integrated Radeon graphics provide:
- CS2: 60-70 FPS on low settings (1080p).
- Fortnite: 45-50 FPS (720p, medium settings).
- GTA V: 55-60 FPS (1080p, low settings).
Turbo Mode is activated when connected to power, raising the CPU frequency to 4.5 GHz. However, in ultrabooks with passive cooling, turbo mode may last only 2-3 minutes due to overheating.
Use Cases: Who is the Ryzen 7 5825U For?
1. Students and Office Workers — Multitasking, cloud service use.
2. Freelancers — Video editing, photo processing, programming.
3. Casual Gamers — Games with moderate requirements.
4. Travelers — Long battery life (up to 12 hours in reading mode).
The chip is not suitable for:
- Professional 3D modeling.
- Streaming AAA games in 4K.
Battery Life: How Long Will the Laptop Last?
With a battery capacity of 60 Wh:
- Web browsing: 10-12 hours.
- Video (1080p): 9-10 hours.
- Maximum load: 3-4 hours.
Power-saving technologies:
- Adaptive Voltage Scaling — voltage reduction under low load.
- Deep Sleep (C6 state) — powering off unused components.
Comparison with Competitors
AMD Ryzen 7 5825U vs Intel Core i7-1260P (2023):
- Multi-thread performance: Ryzen is 18% faster due to 8 cores.
- Graphics: Radeon outperforms Iris Xe in gaming by 10-15%.
- Battery life: AMD is more efficient under similar loads.
Apple M2 (2024):
- Single-thread tasks: M2 is 25% faster (Geekbench 6 Single-Core: ~2100).
- Energy Efficiency: Apple leads (up to 15 hours of operation).
- Price: Laptops with M2 are more expensive by $200–300.
Previous Generation (Ryzen 7 5800U):
- The Ryzen 5825U is 7% faster in multi-thread tests due to cache optimization.
