Specs on Intel Skylake IGP leak

There has been talk and gossip about the upcoming Intel Skylake IGP. Chips based on the IGP are due for launch in 2015. CPU World got a hold of new details about the Skylake GT1, GT2, GT3e and GT4e graphics. The models with the "e" suffix are the psicy ones and come with 64MB eDRAM on quad-core LGA1151 CPUs and 128MB of eDRAM on "H" series Broadwell CPUs for extra performance.

Skylake chips will come with GT2, GT3e or GT4e GPUs, built on 9th generation graphics architecture, and "e" units will be coupled with up to 128 MB of eDRAM memory for extra performance. The GT4e GPU, obviously, is the fastest one, and it will be accompanied by 64MB embedded DRAM on quad-core LGA1151 CPUs, or 128 MB eDRAM on "H" line of BGA processors. GT4e graphics will utilize 72 execution units (EUs), that is 50% more than the best Broadwell GPU, which has 48 EUs. As a result, we expect GT4e-equipped models to be far superior in 3D graphics applications and games to Broadwell chips. As for GT3e and slower GPUs, Skylake processors will have exactly the same number of EUs as Broadwell products, therefore their performance advantage over Broadwell will be only due to graphics architecture enhancements.

Skylake GT3e graphics will incorporate 48 execution units, and will have 64 MB of eDRAM cache. The GPUs will be used in "U" ultra low power systems-on-a-chip.

The most common GT2 graphics will have 24 execution units. It will be available in desktop LGA1151 CPUs, "U" 15W SoCs, "Y" SoCs and "H" series processors.

GT1.5 GPUs will come with 18 execution units (same as Broadwell), and they are going to be integrated into dual-core desktop chips for socket 1151.

Finally, GT1 graphics units will have 12 EUs, that is identical to Broadwell GT1. The GPUs will be used in dual-core socket 1151 CPUs, and in some "U" series chips with 15 Watt TDP. Via CPU world
