Intel Core i5-4590S socket: LGA 1150

What the Core i5-4590S is

The Core i5-4590S is a low power Haswell quad for efficient desktops on LGA 1150. Intel set four cores and four threads at 3.0 GHz base with turbo to 3.7 GHz. Six megabytes of Smart Cache cover office multitasking and light creation. Power is 65 W on 22 nm from May 2014. It trims nearly 20 W against the 84 W i5-4590 while keeping the same turbo ceiling for burst work.

Lower base clocks cut sustained heat in compact towers with modest airflow. Turbo to 3.7 GHz lifts single thread tasks such as spreadsheets and web apps when cooling allows. Four threads handle documents, calls and background tools together. An SSD matters more than clocks for daily feel. Builders pick the S where a standard 84 W quad would strain slim cases.

HD Graphics 4600 drives office monitors without a card. DDR3-1333 and 1600 plus DDR3L variants across two channels to 32 GB feed the chip. The mix is a Haswell socket for fleets that want quad threads at 65 W with mature boards.

Socket and motherboard compatibility

The 4590S fits LGA 1150 on 8 series boards such as H81, B85, H87 and Z87, and on 9 series boards such as H97 and Z97. Haswell is native on both series, so boards accept it with standard firmware. Check the maker CPU list for slim OEM models that list S support per BIOS.

The 75 × 75 mm mount suits stock and low profile coolers. The CPU cooler compatibility by socket guide lists fits. Chips for LGA 1151 never fit. The Socket vs chipset: what decides whether a CPU works guide explains series tiers.

H81 and B85 slim boards are the natural hosts with 65 W power tables. Enable low power limits for quiet fans.

Memory, PCIe and cooling

DDR3-1333 and 1600 with DDR3L options in dual channel to 32 GB is the memory spec. Eight gigabytes suits office images with an SSD. Two sticks aid graphics in meetings. XMP DDR3 can run on Z boards per manual.

Sixteen PCIe 3.0 lanes from the CPU feed one graphics slot or adapters. Most 4590S offices keep integrated video. Chipset lanes add SATA and USB for growth. Nine series boards list M.2 adapter paths per model.

Stock 65 W cooling holds 3.0 GHz quietly in towers. The FCLGA1150 package at 37.5 × 37.5 mm fits push pin units. Keep intakes open for steady turbo in warm rooms.

Upgrade paths

On the same socket the Intel Core i5-4590 at 3.3 GHz to 3.7 GHz is the standard power twin on identical boards with higher base clocks. The Intel Core i7-4790K at 4.0 GHz to 4.4 GHz with eight threads is the large office jump where threads help, needing a Z board and stronger cooling. Both reuse DDR3 memory.

A DDR4 platform needs a new socket and board. The 4590S covers efficient Haswell desks where 65 W quads are the ceiling.
