It looks like Intel will be revamping the naming schema for tyhe integrated procesorrs, at least that is what CPU-world is reporting today. "H" series CPUs will come with HD graphics 530 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.

Here's the skinny from CPU-world:

Earlier reports indicated that the GPU will have up to 72 execution cores, or 50% more than Broadwell Iris Pro graphics. Having many more executions units, Skylake GPUs will be available in 4 tiers, from entry level GT1 to top-of-the-line GT4. Two intermediate tiers, GT2 and GT3, will have 24 and 48 execution units respectively.

To identify different GPU tiers and performance, consumer branding of Skylake GPUs will retain "HD graphics", "Iris" and "Iris Pro" names. Similar to previous generations, Skylake GPUs will also have model numbers, useful for rough (better or worse) comparison of GPU features and performance. However, there will be some differences.

The first HD model numbers, HD 2000 and HD 3000, were introduced in Sandy Bridge microprocessors. Ivy Bridge upped them to 2500 and 4000 to show their increased performance and improved feature-set. Haswell processors had GPU model numbers ranging from 4200 to 5200, and Broadwell had them in the 5300 - 6300 range. Skylake GPUs are not going to follow this trend, and they will employ three-digit numbers instead.

Celeron and Pentium CPUs will have HD graphics 510. This applies to both desktop and mobile budget processors. The "HD graphics" branding without model number will be reserved for Braswell ULV chips.

Core M systems on a chip will integrate HD graphics 515. "U" series SoCs will have higher power rating than Core M, consequentially their GPUs are going to perform better and will have higher model numbers. Overall, there will be three different GPU models in the "U" series, HD graphics 520, Iris 540 and Iris 550. The HD 520 will be available on 15 Watt "U" SoCs. We believe that Iris graphics will be available only on 28 Watt microprocessors.

First desktop Skylake Core i5 and Core i7 processors will have GT2 graphics, which corresponds to HD graphics 530. The same GPU type will be also used on Core i3 Skylake models, via CPU-world.

Rumor: Intel Skylake GPUs get 5xx naming
