What the Core i3-4170T is
The Core i3-4170T brings Haswell threads to 35 W on LGA 1150 for small desktops. Intel set two cores and four threads at a fixed 3.2 GHz with 3 MB of Smart Cache. Power is 35 W on 22 nm from March 2015. No turbo keeps behavior steady for always on use.
Four threads cover office work with background security tools. Fixed clocks simplify thin chassis thermals. The 35 W rating allows slim coolers and small power supplies. Buyers pick the T where a 54 W i3-4170 would overheat a compact case.
HD Graphics 4400 drives office displays with DisplayPort and HDMI output. DDR3-1333 and 1600 over two channels feed the chip. The value is threads at low power without discrete graphics.
Socket and motherboard compatibility
The 4170T fits LGA 1150 on H81, B85, H97 and Z97 with Haswell support. Low power BIOS profiles suit slim OEM boards. Makers list T SKUs explicitly in CPU support tables. Check the list before swapping a standard power i3 for a T in a used slim PC.
DDR3 slots are the only memory option. The Socket vs chipset: what decides whether a CPU works guide covers 8 and 9 series pairing. LGA 1151 boards never accept Haswell despite similar mounts.
Memory, PCIe and cooling
DDR3-1333 and 1600 in two channels to 32 GB suit small office desktops. Eight gigabytes covers fleets with SSDs. Paired sticks help HD 4400 in video calls.
PCIe 3.0 with 16 lanes from the CPU feeds a single slot or NVMe adapter on newer 9 series boards. Most T builds stay integrated to protect thermals. A low profile card fits where chassis airflow allows.
Cooling uses the 75 mm LGA 1150 mount from the CPU cooler compatibility by socket guide. Low height 35 W coolers run quietly. Slim cases need clear intakes to hold 3.2 GHz.
Upgrade paths
On the same socket the Intel Core i7-4790K is not a sensible swap for a 35 W chassis, so compare the Intel Core i5-5675C only where boards and cooling allow a different class. The realistic T ladder is the Intel Core i3-4370T at 3.3 GHz with 4 MB of cache above, sharing boards and power.
A move to a new socket needs a new board and memory. The 4170T covers compact Haswell fleets where 35 W is the ceiling.
