Architecture Overview
The Core i5-8365U is based on the Whiskey Lake-U architecture, a refresh of the Kaby Lake-R line. While still utilizing the 14nm process, Intel refined power delivery and silicon packaging to improve performance and efficiency.
CPU Design
It features 4 physical cores and 8 threads via Hyper-Threading. The architecture employs a ring bus topology, connecting the cores to the 6 MB L3 Smart Cache with low latency, optimizing burst performance.
Memory Subsystem
The integrated memory controller supports dual-channel DDR4 up to 2400 MT/s and LPDDR3 up to 2133 MT/s. This flexibility allows OEMs to choose the memory type that best fits their power and cost targets.
PCIe & I/O
It provides 16 PCIe 3.0 lanes, ensuring sufficient bandwidth for fast NVMe SSDs and external peripherals. The chipset provides additional lanes for I/O expansion.
Overclocking
The processor is locked and features a configurable TDP (cTDP) of 10-25W. This allows laptop manufacturers to adjust the power limit based on the device's thermal solution, favoring either battery life or sustained performance.
- Higher max turbo boost (4.1 GHz vs 3.6 GHz)
- Refined power management
- Better vPro implementation
Key Highlights
