The Intel Pentium E5800 was a desktop processor with 2 cores, launched in November 2010. It is part of the Pentium Dual-Core lineup, using the Wolfdale architecture with Socket 775. Pentium E5800 has 2 MB of L2 cache and operates at 3.2 GHz. Intel is making the Pentium E5800 on a 45 nm production node using 228 million transistors. The multiplier is locked on Pentium E5800, which limits its overclocking potential.
With a TDP of 65 W, the Pentium E5800 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, Pentium E5800 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. Hardware virtualization is available on the Pentium E5800, which greatly improves virtual machine performance.
