Core i5-4590

The Core i5-4590 is a 4-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 3.7 GHz from a base frequency of 3.3 GHz— higher boost clocks directly translate to better single-threaded performance and responsiveness in gaming. It carries 6 MB (total) of L3 cache, plus 256K (per core) of L2 cache and 64K (per core) of L1 cache per core. In the PassMark benchmark (a comprehensive multi-threaded test), it scores 5,376, 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 1,100.

The Core i5-4590 fits into the LGA1150 socket and supports PCIe 3.0 with 16 total PCIe lanes for expansion cards and storage. It supports DDR3 memory at speeds up to DDR3-1600 (faster RAM improves bandwidth-sensitive workloads), with a maximum capacity of 32 GB across 2 channels (dual-channel doubles bandwidth). Integrated graphics: HD Graphics 4600 — allows display output without a dedicated GPU, useful for troubleshooting and light tasks.

The Core i5-4590 is primarily designed for Desktop. Virtualization: VT-x, VT-d, EPT — enables running virtual machines efficiently (important for development and server workloads). Its primary market competitor is the FX-8350.

The Core i5-4590 has a rated TDP (Thermal Design Power) of 84 Watt — this indicates the amount of heat generated under sustained load and determines what cooling solution is needed. It ships with the Yes stock cooler. Recommended cooling: Stock.

At an average price of $51 (MSRP: $192), the Core i5-4590 delivers 105 PassMark points per dollar. It currently holds Rank #624 in the overall cost-benefit ranking — this ranking factors in performance-per-dollar relative to all available processors. Performance ranking position: #1818 out of all indexed processors.
