The Intel Celeron E1400 was a desktop processor with 2 cores, launched in April 2008, at an MSRP of $53. It is part of the Celeron lineup, using the Allendale architecture with Socket 775. Celeron E1400 has 512 KB of L2 cache and operates at 2000 MHz. Intel is building the Celeron E1400 on a 65 nm production process using 105 million transistors. The multiplier is locked on Celeron E1400, which limits its overclocking capabilities. With a TDP of 65 W, the Celeron E1400 consumes typical power levels for a modern PC. Intel's processor supports DDR1, DDR2 and DDR3 memory with a dual-channel interface. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). For communication with other components in the computer, Celeron E1400 uses a PCI-Express Gen 2 connection. Although the processor doesn't come with integrated graphics, certain motherboards with compatible chipsets can provide this capability. Inside the box you will not only find the processor, but also a Yes cooler. The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
