14 DAY TRIAL // August and September will see the introduction of a new generation of desktop and mobile processor units based on Skylake microarchitecture.
Among its many enhancements and improvements, the "Skylake" will have a substantially improved graphics unit. The new "Skylake" GPU will have 72 execution cores, 50% more than Broadwell Iris Pro graphics. CPU World believes, Skylake GPUs will come in 4 tiers, starting with entry level GT1 to high-tier GT4, with the two intermediate models GT2 and GT3 will have 24 and 48 execution units.
The "Skylake" will keep the previous Sandy Bridge and Ivy Bridge prefixes to identify different GPU tiers and performance; however, instead of having four-digit numbers to differentiate between their performance, there will be three digits. Instead of having the "Skylakes" go from HD4200 to HD5200 integrated graphics, they will be HD510 to HD530.
Integrated graphics legacy maintained
The entry level HD510 graphics will be supported by Celeron and Pentiums. This will be applied to desktop and mobile budget processors. The "HD graphics" branding without model number will be reserved for Braswell ULV chips. The Core Ms SoCs will have integrated HD graphics 515. The "U" series will have higher power rating than the Core M. As such, there will be different GPUs in the "U" series. These will be the HD graphics 520, Iris 540 and Iris 550. The HD520 will also be available on 15 Watt "U" SoCs, while the Iris will have a higher power rating to only 28 Watt microprocessors.
The "H" series CPUs will have HD530 graphics and Iris Pro 580. Xeon processors, based on Skylake-H design, will have a "professional" version of those GPUs, that will be branded as HD Graphics P530 and Iris Pro P580.
Apparently, this August will see the first "Skylake" models have GT2 graphics, which means HD530. The same GPU type will also come on Core i3 "Skylake" models.
