CPU Comparison
Intel Core 5 315 vs Intel Core 5 320
A side-by-side comparison of specs, performance and value. The Intel Core 5 315 represents a fundamental shift in mobile computing architecture, launching in April 2026 as part of the Wildcat Lake generation. Built on Intel's cutting-edge 3nm process technology for the compute tile and leveraging TSMC's N6 node for the IO controller, this processor delivers exceptional power efficiency within a strict 15W base power envelope. Unlike traditional Core series chips, the Core 5 315 features a unique hybrid configuration of two high-performance Cougar Cove P-Cores and four Darkmont LP E-Cores, notably operating without Hyper-Threading to maintain a strict 6-core, 6-thread layout optimized for extreme thermal constraints. It integrates a robust NPU capable of 15 TOPS, contributing to a 35 TOPS total platform AI capability. The inclusion of Intel Xe3 Graphics with two Xe-cores provides a substantial leap in integrated visual performance. Designed primarily for thin-and-light laptops, it prioritizes battery life and sustained performance over raw multi-core throughput, making it a highly specialized choice for everyday productivity and seamless AI-accelerated applications.
