HD Graphics (Westmere) (formally Ironlake) is a family of integrated graphics processors introduced by Intel in their Westmere-based microprocessors in 2010. These IGPs are found in Clarkdale and Arrandale-based cores. These are Intel's first generation integrated GPUs.

Each EU has a 128-bit wide FPU that natively executes eight 16-bit or four 32-bit operations per clock cycle.[
