Strengths & Weaknesses

Intel Core i3-1220P

Pros

  • Excellent multi-tasking capability thanks to 8 E-cores
  • Low 28 W power draw enables good battery life in thin laptops
  • Iris Xe 64EU graphics are significantly better than desktop i3 iGPU
  • 10 cores provide strong multi-threaded specs for the price tier
  • Handles everyday web and office tasks with ease

Cons

  • Only 2 P-cores severely limit single-threaded and active workload performance
  • E-cores cannot match P-core performance in demanding applications
  • 28 W base power limits sustained performance in thermally constrained chassis
  • Not suitable for serious content creation or heavy productivity
  • E-core heavy design can cause inconsistent performance in poorly threaded applications
Intel Core i5-1235U

Pros

  • Excellent power efficiency (15W base TDP)
  • 10 cores provide great multitasking
  • Supports fast LPDDR5 memory
  • Good single-core burst performance
  • Hardware AV1 decoding

Cons

  • Only 2 P-cores limit heavy workloads
  • Basic integrated graphics
  • Locked multiplier
  • Soldered to the motherboard

Competitors & Alternatives

Intel Core i3-1220P

Intel Core i5-1235U

Our Verdict on Each

The i3-1220P maximizes core count on a budget by using 8 E-cores, delivering excellent multitasking for thin-and-light laptops but falling short in single-threaded tasks compared to processors with more P-cores.

Best for: The i3-1220P is not a standalone purchase but a component integrated into laptops. When shopping for a thin-and-light laptop in 2022-2023, a machine with the 1220P offers a good balance of everyday performance and battery life for web browsing, office work, and media consumption. However, be aware that the 2 P-cores will limit performance in CPU-intensive applications like video editing or heavy compiling. If your laptop budget allows, stepping up to an i5-1240P or i5-12500P provides 4 P-cores and significantly better sustained performance for a modest price increase.

Read the full review

A highly efficient 15W processor that brings 10-core hybrid architecture to mainstream laptops, offering excellent battery life and solid daily performance.

Best for: Buying a thin-and-light laptop for school, office work, or general everyday use.
