Iris Pro Graphics P555 is an integrated graphics processor introduced by Intel in 2016 for their mainstream Skylake-based microprocessors. This GPU is Skylake's high-end tier GPU incorporating 48 execution units. The 550 GPU is found in high-end mobile (Skylake H) processors.

Unlike the other Skylake Iris GT3 models, this GPU incorporates a larger 128 MiB of eDRAM side cache on-chip for added performance. This GPU also operates at an unusually high base frequency of 650 MHz.
