Strengths & Weaknesses

Intel Core 3 N355

Pros

  • Eight E-cores provide solid multi-thread throughput at low power.
  • Configurable 9 W cTDP enables truly fanless designs.
  • LPDDR5 support improves compatibility for compact, soldered-down designs.
  • 32 EU iGPU with Quick Sync handles modern video codecs including AV1.
  • Embedded lifecycle support makes it attractive for OEMs needing long-term availability.

Cons

  • Single-channel memory caps real-world bandwidth.
  • No P-cores means lower per-thread performance than P+E designs.
  • PCIe 3.0 x9 limits NVMe speeds and high-speed I/O expansion.
  • Multiplier locked; no enthusiast overclocking.
  • 16 GB max memory may be restrictive for heavier workloads or future-proofing.
Intel Core i3-N305

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

The Core 3 N355 is a sensible step up over the Alder Lake-N N305 for always-on, thermally constrained systems: modestly higher clocks, LPDDR5 support, and Intel 7 branding, but still limited by single-channel memory, PCIe 3.0, and no P-core performance.

Best for: Buying or specifying a fanless mini PC, home NAS, or embedded appliance where 15 W (or lower) is a hard constraint and workloads are light.

Read the full review

A 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.
