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. Iris Pro Graphics was the first in the series to incorporate embedded DRAM. [5] Since 2016 Intel refers to the technology as Intel Iris Plus Graphics with the release of ...
Xe-LP is the low power variant of the Xe architecture with removed support for FP64. [22] Xe-LP is present as integrated graphics for 11th-generation Intel Core and the Iris Xe MAX mobile dedicated GPU (codenamed DG1), [6] as well as in the H3C XG310 Intel Server GPU (codenamed SG1). [4]
As of March 2023, Intel has split Vulkan driver support on Windows [84] and on Linux. [85] All drivers are developed by Intel. On Windows, Skylake to Ice Lake supports up to Vulkan 1.3, [86] with limited support after July 2022 as future updates will only cover security fixes. [84] Iris Xe and newer are fully supported as of March 2023. [87]
Intel confirmed ASTC support has been removed from hardware starting with Alchemist and future Arc GPU microarchitectures will also not support it. [ 17 ] Arc Alchemist does not support SR-IOV [ 18 ] or Direct3D 9 natively, instead falling back on the D3D9On12 wrapper which translates Direct3D 9 calls to their Direct3D 12 equivalents.
The shaders support shader model 4.0 features. Architecturally, the GMA X3500 is very similar to the GMA X3000, [12] with both graphics cores running at 667 MHz. The major difference between them is that the GMA X3500 supports Shader Model 4.0 and DirectX 10, whereas the earlier X3000 supports Shader Model 3.0 and DirectX 9. [12]
shader-db is a collection of about 20,000 shaders gathered from various computer games and benchmarks as well as some scripts to compile these and collect some statistics. Shader-db is intended to help validate an optimization. It was noticed that an unexpected number of shaders are not hand-written but generated.
IRIS GL libraries also were unsuitable for opening due to licensing and patent issues [further explanation needed]. These factors required SGI to continue to support the advanced and proprietary Iris Inventor and Iris Performer programming APIs while market support for OpenGL matured.
