Core i5-4300U

The Core i5-4300U is a 2-core / 4-thread processor based on the Haswell (2013−2015) architecture, manufactured on a 22 nm process node. It reaches a maximum boost clock of 2.9 GHz from a base frequency of 1.9 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 3 MB of L3 cache, plus 512 kB of L2 cache and 128 kB of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 2,482, placing it in the Entry Level performance tier as a Legacy generation product. Geekbench 6 single-core (the most relevant metric for gaming FPS) records 607, while multi-core reaches 1,722.

The Core i5-4300U fits into the FCBGA1168 socket and supports PCIe 3.0 with 12 total PCIe lanes for expansion cards and storage. It supports DDR3 memory at speeds up to DDR3L-1600 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 16 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: Intel HD Graphics 4400 — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

Virtualization: Yes — enables running virtual machines efficiently (important for development and server workloads).

The Core i5-4300U has a rated TDP (Thermal Design Power) of 15 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. No stock cooler is included — you will need to purchase an aftermarket cooler separately.

Performance ranking position: #2395 out of all indexed processors.
