CPU Comparison
AMD Ryzen 5 7520C vs Intel Core i3-N305
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.
Adequate for basic office tasks and web browsing. Single-threaded tasks feel slower than on P-core-equipped chips due to Gracemont's lower IPC.
Gaming
Radeon 610M is entry‑level; modern 3D games at low resolution and detail only, but fine for casual and older titles.
Not designed for gaming despite the better-than-expected UHD 770 iGPU. Very light casual games at low resolutions may be playable.
Virtualization
Acceptable for light Linux or Crostini containers, but memory and core count limit heavier VM use.
8 threads allow for basic VMs, but single-channel memory and lack of P-cores limit practical utility.
Efficiency
6 nm process and 15 W TDP enable good performance per watt in thin Chromebooks with long battery life.
Very efficient at idle and light loads due to the all-E-core design. The 9W configurable TDP enables fanless or near-fanless operation.
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 AI acceleration hardware
- Gracemont cores include AVX-VNNI but lack the performance for meaningful AI work
- Not suitable for AI or ML tasks
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
- Not designed for gaming
- UHD 770 (32 EUs) is better than UHD 64EU but still far from gaming-capable
- Single-channel memory severely limits graphics performance
- Older titles at lowest settings and resolutions may be marginally playable

Target Audience
Strengths & Weaknesses
Pros
- 4 cores / 8 threads at 15 W, a clear upgrade over dual‑core Chromebook SoCs
- High boost up to 4.3 GHz for snappy Chrome OS responsiveness
- RDNA 2 Radeon 610M with modern feature set and hardware video decode
- 6 nm process and 15 W TDP enable fanless designs and long battery life
- Dual‑channel LPDDR5‑5500 improves both CPU and iGPU performance
Cons
- Only 4 PCIe 3.0 lanes; NVMe speed and expandability are limited
- 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
- 8 cores provide good parallel throughput for the price
- Very low power consumption with 9W configurable TDP
- UHD Graphics 770 is better than expected for this tier
- Fully dynamic clock domains for granular power management
- Supports AVX-VNNI instruction extensions
- Enables very affordable mini PCs and Chromebooks
Cons
- No P-cores means weak single-threaded performance
- Single-channel memory halves bandwidth
- Only 9 PCIe 3.0 lanes severely limit expansion
- 6MB L3 cache is small for 8 cores
- Gracemont IPC is significantly lower than Golden Cove
- PCIe 3.0 is a generation behind the 4.0 support on U-series chips

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 unique all-E-core processor that offers 8 threads of parallel performance at very low power, but the absence of any P-cores means single-threaded performance is significantly behind hybrid chips. Best suited for devices where core count marketing and power efficiency matter more than snappy responsiveness.
Best for: Budget mini PC or Chromebook purchase where 8-core parallelism at low power is valued, and single-threaded performance is not critical.
