The Intel Pentium D 940 was a desktop processor with 2 cores, launched in January 2006, at an MSRP of $423. It is part of the Pentium D lineup, using the Presler architecture with Socket 775. Pentium D 940 has 2 MB of L2 cache and operates at 3.2 GHz. Intel is building the Pentium D 940 on a 65 nm production process using 376 million transistors. The multiplier is locked on Pentium D 940, which limits its overclocking capabilities.
With a TDP of 130 W, the Pentium D 940 consumes a lot of power, so good cooling is definitely needed. Intel's processor supports DDR1, DDR2 and DDR3 memory with a dual-channel interface. Actual memory technology support depends on the chosen motherboard, because the memory controller is located on the motherboard (not in the processor). For communication with other components in the system, Pentium D 940 uses a PCI-Express N/A 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. Hardware virtualization is available on the Pentium D 940, which greatly improves virtual machine performance.
