The Intel Celeron G1101 was a server/workstation processor with 2 cores, launched in January 2010, at an MSRP of $85. It is part of the Celeron lineup, using the Clarkdale architecture with Socket 1156. Celeron G1101 has 2 MB of L3 cache and operates at 2.266 GHz. Intel is building the Celeron G1101 on a 32 nm production process using 382 million transistors. The multiplier is locked on Celeron G1101, which limits its overclocking capabilities. With a TDP of 73 W, the Celeron G1101 consumes typical power levels for a modern PC. Intel's processor supports DDR3 memory with a dual-channel interface. The highest officially supported memory speed is 1066 MT/s, but with overclocking (and the right memory modules) you can go even higher. ECC memory is supported, too, which is an important capability for mission-critical systems, to avoid data corruption. For communication with other components in the computer, Celeron G1101 uses a PCI-Express Gen 2 connection. This processor features the Intel HD integrated graphics solution. The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability. Hardware virtualization is available on the Celeron G1101, which greatly improves virtual machine performance.
