AMD Ryzen 5 7545U: Balance of Power and Longevity for Mobile Tasks
Architecture and Process Technology: Zen 4 and RDNA 3 in a Compact Form Factor
The AMD Ryzen 5 7545U processor, created under the codename Phoenix2, is a mobile solution built on the Zen 4 architecture and TSMC's 4nm process technology. This is AMD's first laptop processor to surpass the 5nm boundary, allowing for increased transistor density and reduced power consumption.
Key CPU Specifications:
- 6 cores (all Performance cores) and 12 threads;
- Base frequency: 3.2 GHz;
- Maximum turbo frequency: up to 4.9 GHz;
- L3 cache: 16 MB;
- Support for DDR5/LPDDR5x and PCIe 4.0.
The integrated Radeon 740M graphics are based on the RDNA 3 architecture and include 4 compute units (CUs) with a frequency of up to 2.5 GHz. This enables support for technologies such as FSR (FidelityFX Super Resolution), Ray Tracing (in a limited capacity), and output to displays with resolutions up to 8K. It is important to note that the iGPU has 2 GB of dedicated video memory (using system RAM), which is beneficial for multimedia tasks.
Architecture Features:
- AI accelerator (based on XDNA) for tasks like noise reduction or image optimization in video conferences;
- Support for AV1 for encoding and decoding video, which is critical for streaming and handling 4K content.
Power Consumption and TDP: Balance for Thin Laptops
The nominal TDP of the processor is 28 W, but actual values can vary from 15 W (in power-saving mode) to 35 W (under peak loads). This makes the Ryzen 5 7545U ideal for ultrabooks and business laptops, where a compromise between performance and battery life is essential.
Power Management Technologies:
- Precision Boost 2 — dynamically increases core frequencies based on load and temperature;
- Adaptive Power Management — automatically reduces voltage when idle;
- Eco Mode that limits TDP to 15 W for maximum battery life.
Performance: From Office to Light Gaming
Office Tasks and Multitasking
In PCMark 10 tests, the Ryzen 5 7545U scores around 5800 points, which is 15% higher than its predecessor, the Ryzen 5 6600U. This indicates comfortable performance when working with dozens of browser tabs, office applications, and even light video editing in Premiere Pro (rendering 1080p video takes about 8 minutes).
Turbo Mode: When Maximum Performance is Required
When turbo mode is activated (up to 4.9 GHz), the processor shows a boost of up to 30% in single-threaded tasks, for example, in Excel with large spreadsheets or Photoshop. However, this mode lasts no more than 2-3 minutes in thin laptops due to cooling limitations.
Gaming: Capabilities of Radeon 740M
In gaming, the iGPU shows the following results (Low/Medium settings, 1080p):
- CS2 — 60-70 FPS;
- Fortnite — 45-55 FPS (with FSR);
- GTA V — 50-60 FPS;
- Hogwarts Legacy — 25-30 FPS (only with FSR Performance).
For comfortable gaming, it is better to choose a laptop with additional cooling and dual-channel RAM.
Usage Scenarios: Who is the Ryzen 5 7545U Suitable For?
- Students and freelancers — work with documents, online courses, light video editing.
- Office workers — multitasking, video conferencing, cloud services.
- Casual gamers — games like CS2 or indie projects.
- Travelers — battery life up to 10 hours (with a large capacity battery).
Not Suitable For:
- Professional gamers (require a discrete GPU);
- Video editors working with 4K/8K content.
Battery Life: How Long Will the Laptop Last?
With a battery capacity of 60 Wh, the operating time is:
- Web surfing (brightness 150 nits) — 9-10 hours;
- Video (YouTube, 1080p) — 7-8 hours;
- Load (rendering + Wi-Fi) — 3-4 hours.
Energy-Saving Technologies:
- AMD PowerNow! — automatically disables unused cores;
- Panel Self Refresh — reduces the refresh rate in static scenes.
Comparison with Competitors: Who is Ahead?
AMD Ryzen 5 7640U (Zen 4)
A more powerful sibling with 8 cores and Radeon 760M. It loses on price but wins in multithreaded tasks (about 20% difference).
Intel Core i5-1335U (Raptor Lake)
The 13th generation Intel offers similar single-threaded performance, but the Ryzen 5 7545U outperforms it by 12-18% in multithreading. The Iris Xe graphics lag behind the Radeon 740M in gaming (up to a 25% difference).
Apple M2
The M2 is more efficient in power consumption (battery life is 2-3 hours longer), but it struggles with compatibility with Windows programs and games. For cross-platform tasks, Ryzen offers more flexibility.
Pros and Cons of Ryzen 5 7545U
Strengths:
- High multithreaded performance;
- Support for DDR5 and PCIe 4.0;
- Good integrated graphics;
- Optimal TDP for thin laptops.
Weaknesses:
- Turbo mode is unstable in compact cases;
- No support for Thunderbolt 4;
- Higher price compared to Intel i5 in the same segment.
Recommendations for Choosing a Laptop
1. Type of Device: ultrabooks (ASUS ZenBook, Lenovo Yoga), business models (HP EliteBook), budget laptops (Acer Swift).
2. RAM: at least 16 GB DDR5 (for dual-channel graphics mode).
3. Storage: SSD NVMe 512 GB and above.
4. Screen: IPS panel with sRGB coverage 90%+ for color work.
5. Cooling: check reviews for throttling under load.
Model Examples:
- Lenovo ThinkPad T14 Gen 4 — reliability and keyboard for office work;
- ASUS Vivobook Pro 15 — OLED screen for creative tasks.
Final Conclusion
The AMD Ryzen 5 7545U is an ideal choice for those looking for a versatile laptop with performance to spare for 3-4 years. It will handle office work, light creative tasks, and even casual gaming while maintaining battery life of up to 8 hours. If you're not ready to pay a premium for discrete graphics and want a highly portable device, this processor is worth considering. However, for professional tasks (rendering, AAA gaming), it is better to choose models with Ryzen 7 or the H-series.
