CPU Comparison
AMD Ryzen 5 7520C vs Intel Core 3 100U
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 web browsing, document editing, spreadsheet work, and video conferencing without issues. More demanding productivity applications will show limitations.
Gaming
Radeon 610M is entry‑level; modern 3D games at low resolution and detail only, but fine for casual and older titles.
The 64-EU UHD Graphics is not designed for modern gaming. Older or very lightweight titles at low resolutions may run, but anything recent will struggle significantly.
Virtualization
Acceptable for light Linux or Crostini containers, but memory and core count limit heavier VM use.
VT-x and VT-d are supported, enabling basic virtual machine use, but limited cores and memory bandwidth restrict practical utility.
Efficiency
6 nm process and 15 W TDP enable good performance per watt in thin Chromebooks with long battery life.
The 15W base TDP with 55W PL2 makes this chip well-suited for thin-and-light laptops where battery longevity matters more than peak performance.
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 or AI acceleration hardware
- CPU-based inference is possible but impractically slow for meaningful AI workloads
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
- 64-EU UHD Graphics lacks the compute power for modern game titles
- Suitable only for casual 2D games or very old 3D titles at low settings
- eGPU support depends on laptop Thunderbolt implementation, not guaranteed

- Radeon 610M has just 2 CUs, restricting gaming and GPU compute potential
- Max memory officially limited to 16 GB, typical of budget Chromebooks
- No unlocked multiplier; no overclocking support
- Zen 2 CPU architecture is several generations old behind Zen 4/Zen 5
Pros
- Hybrid architecture brings modern design to the budget segment
- Low 15W TDP enables excellent battery life in thin laptops
- Supports both DDR4 and DDR5 memory for OEM flexibility
- P-Cores boost to a competitive 4.7 GHz
- UHD Graphics 64EU handles 4K output and hardware video decoding
- VT-x and VT-d virtualization support included
- Significant upgrade over Pentium and Celeron alternatives
Cons
- Only 2 P-Cores limit single-threaded intensive workloads
- 64-EU iGPU is insufficient for any meaningful gaming
- Only 8 PCIe 4.0 lanes restrict storage expansion
- BGA socket means the CPU is permanently soldered and non-upgradeable
- No ECC memory support
- 10MB L3 cache is modest for a 6-core chip
- No Hyper-Threading on E-Cores caps thread count at 8
