The Intel Core 2 Quad Q9300 was a desktop processor with 4 cores, launched in March 2008. It is part of the Core 2 Quad lineup, using the Yorkfield architecture with Socket 775. Core 2 Quad Q9300 has 6 MB of L2 cache and operates at 2.5 GHz. Intel is building the Core 2 Quad Q9300 on a 45 nm production process using 456 million transistors. The multiplier is locked on Core 2 Quad Q9300, which limits its overclocking capabilities.
With a TDP of 95 W, the Core 2 Quad Q9300 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 computer, Core 2 Quad Q9300 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.
Hardware virtualization is available on the Core 2 Quad Q9300, which greatly improves virtual machine performance.
