Intel‘s 4th-gen Core processors will also debut a brand new Iris graphics system, with the chip company splitting its new line-up into multiple tiers for ultrabooks, thin-and-lights, and mainstream PCs. Ultrabooks powered by the most frugal of Intel’s 4th-generation Haswell chips, the U-Series, will get Intel HD, HD Graphics 4600, or HD Graphics 5000, but those machines that can stand a little extra power consumption will get either Iris (for thin-and-lights) or Iris Pro (for mainstream) for at least a doubling in 3D processing performance.
