Verdict

The Intel Core Ultra 5 115U is a 7nm Meteor Lake-U mobile processor featuring 8 cores (2 Performance, 4 Efficient, and 2 Low-Power Efficient) and 10 threads, with a max turbo frequency of 4.2 GHz and a 10MB L3 cache. Its main strengths include an integrated AI Boost NPU for machine learning tasks, support for up to 96GB of fast LPDDR5x-7467 memory, and 4-core Intel Arc Graphics capable of ray tracing and 4K encoding. However, it is an entry-level SKU within the Ultra series, featuring fewer E-cores and lower clock speeds than models like the 125U, which results in approximately 10-15% slower multi-threaded performance and reduced gaming capabilities compared to its higher-tier counterparts.

What customers like about Intel Core Ultra 5 115U?

  • Integrated AI features: Equipped with a dedicated Neural Processing Unit (NPU) that maintains standard Meteor Lake AI performance despite lower core counts.
  • Energy efficiency: Low base power consumption (15W) makes it suitable for thin-and-light laptops and potentially improves battery life.
  • Modern connectivity: Built-in support for advanced standards like Thunderbolt 4, Wi-Fi 6E/7, and high-speed DDR5 memory (up to 5600 MT/s).
  • Entry-level accessibility: Positioned as a budget-friendly entry point for users wanting 'AI PC' capabilities without the higher cost of premium chips.
  • Multitasking: 10 threads allow for reasonable handling of simultaneous everyday tasks like browsing with many tabs and basic document editing.

What customers dislike about Intel Core Ultra 5 115U?

  • Lowest tier performance: As the slowest SKU in the Meteor Lake lineup, it features only 2 Performance cores and half the Efficiency cores of other Ultra 5 models.
  • Weak integrated graphics: Scaled down to just 3 Xe-cores, making it the only SKU in the series with such low graphical power, limiting it to low-setting 1080p gaming.
  • Potential for thermal issues: Some users report it can heat up quickly when pushed to its maximum 57W turbo power, requiring active cooling to avoid throttling.
  • Misleading branding: Reviewers have criticized the 'Ultra' naming as potentially deceptive since it may perform slower than non-Ultra chips like the Core 5 120U.
  • Scheduling lag: Some reports indicate occasional lag during heavy multitasking due to the split between P, E, and Low Power E-cores.
