When building a Hackintosh with both types of GPU we can find that, although the dGPU is much more powerful than the iGPU, if it is not properly installed and recognized by the system, the video encoding will fail.

Macs with an integrated graphics card (iGPU) and a dedicated one (dGPU) use the integrated one for video encoding and decoding. Note: based on the excellent article ' General Framebuffer Patching Guide (HDMI Black Screen Problem)' by on the 'Framebuffer patch' functionality of Hackintool app and on the Desktop Coffee Lake Dortania's guide. How to set the integrated graphics card Intel UHD Graphics 630 Coffee Lake Refresh (9 generation) in headless mode (without cable) to be used in video encoding tasks, bringing the image to the monitor with Radeon RX 580, adding hardware video encoding and decoding to the system, or as main card. The GPU may reserve up to 1.7GB.Building a CustoMac Hackintosh: Buyer's Guide The GPU Shares the System's RAM which varies according to the System. The operating memory clock depends on which speed the System's RAM is running and which memory type is installed and is ultimately limited by the highest operating speed that the processor supports.ĭepending on whether or not the System's RAM is Dual-Channeled, it can access either a 64-bit or 128-bit Memory Interface. The GPU Codenamed GT2 offers 184 Shader Processing Units, 23 TMUs and 3 ROPs The central unit initially runs at 300MHz and goes up to 1150MHz in Turbo Mode. It includes support for DirectX 12.1, OpenCL 2.1 and OpenGL 4.6, as well as DDR4 Memory Support.

The Coffee Lake Architecture succeeds the Kaby Lake Architecture and aims for increased CPU and Graphics Performance, within the same Power Requirements. Intel UHD Graphics 630 are Integrated Graphics in some of Intel's Coffee Lake Processors. UHD Graphics 630 Game Requirement Analysis
