What the Core i3-7300T is
The Core i3-7300T is a two core, four thread desktop processor from Kaby Lake. It launched in January 2017 with a fixed 3.5 GHz at 35 W. Two cores with Hyper-Threading plus 4 MB cache cover low power offices where threads and cache both help.
Four megabytes of Smart Cache feed multitasking with office suites. The fixed 3.5 GHz gives steady pace for documents and calls. Thirty five watts suit thin towers.
HD Graphics 630 from 350 MHz to 1100 MHz drives office monitors with 4K support. Hardware decode keeps streaming smooth. The chip suits fleets where many seats need quiet pace.
On 14 nm the 7300T leads low power i3 parts above the 7100T on clocks and cache. Makers pick it for small form factor offices. Locked multiplier keeps it stock.
Socket and motherboard compatibility
The 7300T fits LGA 1151 revision 1 only. Two hundred series boards accept it natively, while 100 series may need a BIOS update. Three hundred series boards never support it.
The Socket vs chipset: what decides whether a CPU works guide covers board generations. Thin boards pair it with DDR4 for quiet service.
The Core i3-7300 on the same socket adds 500 MHz at 51 W. The Pentium Intel Pentium G4620 is the lower cost thread alternative.
Memory, PCIe and cooling
DDR4-2133/2400 or DDR3L up to 64 GB in two channels is the memory design. Dual channel operation helps graphics. SSD choice decides boot feel.
Sixteen PCIe 3.0 lanes support graphics or NVMe storage. Office builds use integrated output. Low profile 35 W cooling covers the load.
The 75 mm cooler pattern matches LGA 1155, 1150 and LGA 1200. Airflow matters more than cooler brand.
Upgrade paths
On the same socket Core i3-7320 adds clocks, while Core i5-7400T brings four cores at the same 35 W. Both reuse board and DDR4.
Past revision 1 a new board is needed. Storage upgrades usually come first.
