The Intel Pentium G640 is a desktop processor with 2 cores, launched in June 2012. It is part of the Pentium lineup, using the Sandy Bridge architecture with Socket 1155. Pentium G640 has 3 MB of L3 cache and operates at 2.8 GHz. Intel is making the Pentium G640 on a 32 nm production node using 504 million transistors. The multiplier is locked on Pentium G640, which limits its overclocking potential.
With a TDP of 65 W, the Pentium G640 consumes typical power levels for a modern PC. Intel's processor supports DDR3 memory with a dual-channel interface. For communication with other components in the system, Pentium G640 uses a PCI-Express Gen 3 connection. This processor features the Intel HD (Sandy Bridge) integrated graphics solution.
Hardware virtualization is available on the Pentium G640, which greatly improves virtual machine performance. Programs using Advanced Vector Extensions (AVX) can run on this processor, boosting performance for calculation-heavy applications.
