Core 2 Duo E7400 has 3 MB of L2 cache and operates at 2.8 GHz. Intel is making the Core 2 Duo E7400 on a 45 nm production node using 228 million transistors. The multiplier is locked on Core 2 Duo E7400, which limits its overclocking potential. With a TDP of 65 W, the Core 2 Duo E7400 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 machine, Core 2 Duo E7400 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.
