Skylake has an interesting and capable GPU, gaming wise you can expect entry-level dedicated graphics performance but we like to see the unit more as a video processor. Ultra HD screens are supported up-to 60Hz through DisplayPort 1.2, HDMI 2.0 unfortunately is not supported and thus an Ultra HDTV can't be used at 60 Hz.
IRIS PRO 580 DESKTOP DRIVERS
Intel however has a nice workaround, as the drivers support a hybrid decoder that makes use of both the CPU and GPGPU algorithms. For those interested, HEVC hardware decoding support is not embedded. The Quick Sync video encoder has had a speed bump as well and, according to Intel, now offers better quality. The iGPU is now compatible with DirectX 11.2 and DirectX 12 feature level 11_1, OpenGL 4.4 and OpenCL 2.0. The EUs are arranged in sets of 4 modules. For Skylake the minimum number used in the lower end SKUs is 12 EUs, thus running up-to 72 units for the high end GT4e model. Haswell processors have up-to 20 EUs, so the performance should be up compared to the previous generation iGPUs.
IRIS PRO 580 DESKTOP PRO
Iris Pro Graphics was the first in the series to incorporate embedded DRAM. Intel Iris Graphics and Intel Iris Pro Graphics are the IGP series introduced in 2013 with some models of Haswell processors as the high-performance versions of HD Graphics. Intel HD Graphics is a series of Intel's integrated graphics processors (IGPs) introduced in 2010 that are manufactured on the same package or die as the central processing unit (CPU). The Intel 5000 series integrated graphics core is incorporated onto the same die as the CPU, and it also has access to Intel's automatic overclocking Turbo Boost features. The embedded graphics core is an updated model though revamped, improved and definitely more powerful with an improved video en/decoder now as well. The IGP inside the processor is called the Intel Graphics Media Accelerator HD, and is derived from existing Intel graphics products, but has some nice new improvements.
