What reviewers say

Reviews find strong gaming performance and better efficiency than Sandy Bridge, but gains are too small to justify upgrading from a Core i5-2500K. Integrated graphics improve but remain limited for demanding games. Bit-tech finds high temperatures when pushing its sample to an aggressive overclock.

Cores and clocks

Cores: 4
Threads: 4
Base clock: 3.4 GHz
Boost clock: 3.8 GHz
L3 cache: 6 MB
Cores: Four cores without Hyper-Threading; Intel Turbo Boost 2.0 supported. Intel VT-x supported; VT-d is not supported on this model.
Clocks: Maximum turbo is a single-core frequency; sustained clocks and overclocking depend on motherboard support and cooling. Intel publishes TDP without a separate maximum turbo-power figure.

Graphics and AI

Built-in graphics: Yes
Graphics: Intel HD Graphics 4000; 650 MHz base, up to 1.15 GHz; three displays; Quick Sync Video. Intel's launch information identifies DirectX 11 support; available outputs depend on the motherboard.

Platform

Socket: LGA1155
Base power: 77 W
Unlocked: Yes
Memory support: Up to 32 GB; two channels; DDR3-1333/1600; 25.6 GB/s maximum bandwidth; ECC not supported.
PCIe: PCIe 3.0; configurations up to 1×16, 2×8 or 1×8+2×4, as listed by Intel. Motherboard support determines available slot configurations.
Process: 22 nm; Ivy Bridge; 3D tri-gate transistors; 37.5 × 37.5 mm package; 67.4°C Tcase limit, not a junction-temperature limit.
Cooler: LGA1155-compatible cooling required. Intel announced the quad-core family on 23 April 2012; Ars Technica's contemporaneous launch report quotes Newegg confirming retail sale on 29 April. The archived maker sale notice could not be read, so the day is supported by named secondary retail coverage.
