It looks like Google fails to correctly decipher Intel Isis (probably because it is still new). If you were searching Intel Isis, OP probably meant Intel Iris[0]. Intel Iris and Intel Iris Pro were introduced with Haswell processors.

> Intel Iris Graphics and Intel Iris Pro Graphics are new brands for Intel's high-end integrated graphics introduced with some variants of its Haswell processors. They utilize the same basic blocks as the HD series, but have a higher maximum frequency, and additional eDRAM cache for the "Pro" series.
