CPU Comparison
AMD Ryzen 5 7520C vs Intel Core 5 120U
A side-by-side comparison of specs, performance and value. The AMD Ryzen 5 7520C is a 15 W, 4‑core/8‑thread Chromebook SoC from AMD’s Mendocino family, built on a 6 nm Zen 2 CPU core and an RDNA 2 Radeon 610M iGPU, designed to bring modern performance and long battery life to mainstream Chromebooks.
The Bottom Line
Overview & Launch
Specifications Compared
Performance Compared
Productivity
Noticeably quicker than older dual‑core Chromebook SoCs for multitasking, Android apps, and browser workloads.
Handles office suites, browsers with many tabs, and light creative workflows well. Multi-thread performance is limited by the 15W PL1 and lack of Hyper-Threading on E-cores.
Gaming
Radeon 610M is entry‑level; modern 3D games at low resolution and detail only, but fine for casual and older titles.
Fine for esports and older/light titles at 1080p with low–medium settings; not intended for AAA gaming at high settings.
Virtualization
Acceptable for light Linux or Crostini containers, but memory and core count limit heavier VM use.
Efficiency
6 nm process and 15 W TDP enable good performance per watt in thin Chromebooks with long battery life.
The 15W base power and Intel 7 process help thin-and-lights achieve long battery life in typical office use, especially with LPDDR memory.
Specialized Performance
AI / ML
- No dedicated AI accelerator; inference relies on CPU/iGPU
- Fine for on‑device Chrome OS AI features, not for heavy ML workloads
- No dedicated NPU; AI workloads rely on CPU and GPU.
- Intel DL Boost (VNNI) is supported on the CPU, enabling some acceleration for inference.
- Suitable for small-scale, occasional local inference; not intended for heavy AI training or large LLM serving.
Content Creation
Gaming
- Radeon 610M with only 2 CUs limits gaming potential
- Suitable for 2D, e‑sports, and older titles at low settings
- Not aimed at AAA gaming or high refresh rate gameplay
- Integrated Iris Xe 80 EU is sufficient for e-sports titles and older games at 1080p.
- Modern AAA titles will generally require low settings and may still struggle; not a gaming-focused part.

Our Verdict on Each
A solid step up from older dual‑core Chromebook chips, with competitive CPU performance and modern RDNA 2 graphics, but limited by a small GPU and no upgrade path beyond typical Chromebook constraints.
Best for: Buying a Chromebook Plus or mainstream Chromebook where you want better CPU and iGPU performance than older Intel or AMD dual‑core designs, without sacrificing battery life.
Read the full reviewA competent 15W chip that delivers snappy day-to-day performance and solid battery life in mainstream laptops, but it’s not built for sustained heavy workloads or AAA gaming. The 2P+8E layout and 5.0 GHz P-core boost are strong for the segment; the 80 EU iGPU handles everyday graphics and light gaming adequately. Choose it for everyday work and study rather than intensive creator tasks.
Best for: Everyday productivity, study, and light creative work in a thin-and-light laptop where battery life and cost matter more than peak multi-core performance.
