The Intel Celeron D 330 was a desktop processor with 1 core, launched in June 2004. It is part of the Celeron D lineup, using the Prescott architecture with Socket 775. Celeron D 330 has 256 KB of L2 cache and operates at 2.667 GHz. Intel is building the Celeron D 330 on a 90 nm production process using 125 million transistors. The multiplier is locked on Celeron D 330, which limits its overclocking capabilities. With a TDP of 84 W, the Celeron D 330 consumes a good deal of power, so decent cooling is needed. Intel's processor supports DDR1, DDR2 and DDR3 memory with a dual-channel interface. For communication with other components in the machine, Celeron D 330 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.
