The Intel Celeron 450 was a desktop processor with 1 core, launched in August 2008. It is part of the Celeron lineup, using the Conroe architecture with Socket 775. Celeron 450 has 512 KB of L2 cache and operates at 2.2 GHz. Intel is building the Celeron 450 on a 65 nm production process using 105 million transistors. The multiplier is locked on Celeron 450, which limits its overclocking capabilities.
With a TDP of 35 W, the Celeron 450 consumes only little energy. Intel's processor supports DDR1, DDR2 and DDR3 memory with a dual-channel interface. For communication with other components in the machine, Celeron 450 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.
The SSE4 instruction set is not supported, which can cause problems with modern games, as they require that capability.
