Not applicable for systems running Windows® 10.įrequently Asked Questions for Intel® Graphics Memory on Windows® 10įrequently Asked Questions for Graphics Memory on Windows 8*/8.Intel® Graphics Products support a wide range of Operating Systems. IGD Aperture use of de-swizzle or linearization applicable only on Windows® 7 or older operating systems.IGD Aperture applicable only for integrated graphics on 10th Generation Intel® processors and older.IGD Aperture Size (Default) = 256 MB (for 10th Generation Intel® processors and older) Note A large IGD Aperture Size is not a good idea 100% of the time, since this will increase BAR space in system address space. Not applicable to Windows® 10).Īpplications interact with BAR, which in turn redirects to the system memory that is dedicated for integrated graphics or regular system memory for de-swizzle. Application requiring de-swizzle or linearize view of graphics data (only applicable to Windows® 7 or older operating systems.Application requires direct access to system memory dedicated for integrated graphics.The PCIe BAR/Window for integrated graphics is provided in two cases:

Some BIOS or UEFIs also allow users to define IGD Aperture Size, which provides the size of Peripheral Component Interconnect Express (PCIe) Base Address Registers (BAR)/Window for integrated graphics.

See more information at Frequently Asked Questions for Intel® Graphics Memory on Windows® 10. Total IGD graphics memory is based on the operating system and not equal to Graphics Video Max Memory. Any not used for the above two is used as Video Memory (VRAM).This memory is never available for regular system memory, instead it's utilized for: Most BIOS or Unified Extensible Firmware Interfaces (UEFI) define the Graphics Video Max Memory as the maximum amount of system memory dedicated to integrated graphics solely for an Integrated Graphics Device (IGD). Changing IGD Aperture Size settings in BIOS may result in varied system performance.
