Intel Core i7-4790T socket: LGA 1150

What the Core i7-4790T is

The Core i7-4790T brings i7 threads to 45 W for slim Haswell desktops on LGA 1150. Intel set four cores and eight threads at 2.7 GHz base with turbo to 3.9 GHz. Eight megabytes of Smart Cache serve creation in small bodies. Power is 45 W on 22 nm from May 2014. High turbo keeps single thread bursts near the 84 W i7-4790 while base clocks hold sustained heat down.

Low base power suits mini PCs and all in one designs with limited fans. Bursts to 3.9 GHz keep UI work direct. Eight threads handle builds and edits beside office apps with an SSD. The mix is rare among Haswell quads, since few combine i7 threads with 45 W. Buyers pick the T where 65 W S parts still run too warm.

HD Graphics 4600 from 350 MHz to 1.2 GHz drives office and media displays. DDR3-1333 and 1600 with DDR3L variants across two channels to 32 GB feed cores and graphics. It is a Haswell socket for compact performance hosts that need threads without tower cooling.

Socket and motherboard compatibility

The 4790T fits LGA 1150 on H81, B85, H97 and Z97 with Haswell support. Makers list 45 W T support per board with tuned power tables. Check the CPU list before swapping a standard i7 for a T in a used slim PC.

DDR3 is the only memory type. The Socket vs chipset: what decides whether a CPU works guide covers series pairing. Boards for LGA 1151 never accept Haswell. The 75 mm mount from the CPU cooler compatibility by socket guide fits low profile 45 W coolers.

All in one boards favor this SKU for thermal headroom. Confirm display and storage wiring on compact models.

Memory, PCIe and cooling

DDR3-1333 and 1600 with DDR3L options in dual channel to 32 GB suit small performance PCs. Sixteen gigabytes covers creation with an SSD. Two sticks aid HD 4600 in video work. Board specs set voltage for low power use.

Sixteen PCIe 3.0 lanes from the CPU feed one slot or adapters. Most 4790T builds stay integrated to hold 45 W. Chipset lanes add SATA and USB. Low profile cards fit where airflow allows.

Low profile 45 W cooling holds 2.7 GHz quietly with bursts to 3.9 GHz. Keep vents open in cabinets, since turbo heat spikes quickly in small volumes.

Upgrade paths

On the same socket the Intel Core i7-4790S at 3.2 GHz to 4.0 GHz is a higher base 65 W step where cooling allows. The Intel Core i5-4690T at 2.5 GHz to 3.5 GHz is a lower thread 45 W quad where i7 threads matter less. Both share DDR3 boards.

A new platform needs a new board and memory. The 4790T covers slim Haswell performance where i7 threads at 45 W are required.
