The Intel Celeron D 346 was a desktop processor with 1 core, launched in October 2004. It is part of the Celeron D lineup, using the Prescott architecture with Socket 775. Celeron D 346 has 256 KB of L2 cache and operates at 3.06 GHz. Intel is making the Celeron D 346 on a 90 nm production node using 125 million transistors. The multiplier is locked on Celeron D 346, which limits its overclocking potential.
With a TDP of 73 W, the Celeron D 346 consumes typical power levels for a modern PC. Intel's processor supports DDR1, DDR2 and DDR3 memory with a dual-channel interface. For communication with other components in the system, Celeron D 346 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.
