Overview
SummaryThe Intel Pentium 1405 is a server processor with 2 cores and 2 threads, built on the Sandy Bridge architecture. It launched in Apr 2012. Clocks run from 1.2 GHz base to 1.8 GHz boost. A 5-MB L3 cache backs the cores (2.8 MB per core). It addresses DDR3 memory up to 375 GB across 2 channels. The chip drops into the FCLGA1356 socket and exposes PCIe 3.0 (24 lanes). Rated TDP is 40 W. Notable platform capabilities: Extended Page Tables (EPT).
Core Configuration
5 specsThe Intel Pentium 1405 has 2 physical cores and runs 2 logical threads. It does not support simultaneous multithreading, so its thread count equals its core count. It runs at a base clock of 1.20 GHz and boosts up to 1.80 GHz.
