    [Updated] Stork's Thunderbolt Build: i5-3570K | GA-Z77X-UP5-TH | GTX 760

    You're welcome. We are all here to learn and educate.

    [Updated] Stork's Thunderbolt Build: i5-3570K | GA-Z77X-UP5-TH | GTX 760

    Yes but you missed the point about ENCODE/DECODE. Those processes are MUCH more intensive than rendering and something that the 3770K nor the HD4000 GPU particularly powerful at compared to the AMD GPU. And for ENCODE/DECODE FCPX does NOT utilise the AMD GPU if your HD4000 is enabled and you are...

    [Updated] Stork's Thunderbolt Build: i5-3570K | GA-Z77X-UP5-TH | GTX 760

    Rendering, playback and effects is very different from ENCODE/DECODE. Yes the AMD GPU will be used for that (it's what I refer to as "accelerated GUI" but when it codes to finally creating your output files - i.e. ENCODE, then the AMD GPU will NOT be used but instead HD4000 + CPU (for H.264) and...

    [Updated] Stork's Thunderbolt Build: i5-3570K | GA-Z77X-UP5-TH | GTX 760

    Yes the HD4000 & AMD cards work well together as basic accelerated GUI. But not if you need H/W encode/decode of video based on HEVC codecs. The HD4000 cannot do HEVC and if it is enabled then then the AMD card is ignored and the CPU is used to encode/decode HEVC based video. Also, H.264 encode...

    Won't Wake from Sleep and Reboots with Radeon RX 480/580

    It depends on what you are trying to achieve. That SSDT file was required during High Sierra days but Mojave, things have progressed and should not be necessary.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Both GPU's "working" does not mean dGPU is encoding...it will decode but not encode WITHOUT the dummy kext (unless you are using 10.14.5 BETA). You can prove it to yourself by examining the IOREG WITH and WITHOUT the dummy kext. See this.

    That comment seems a little disrespectful. Joining date should have no relevance on expertise or knowledge.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    For your CPU, it's better to use iMac13,2 - it's the closest match. For proper CPU power management, you need to set the right config parameters (XCPM or SSDT.aml) but that's outside the scope of this thread and you should start a separate thread in the desktop section where others will help...

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    That's normal. Your options are: 1. Enable IGPU in BIOS, Inject->Intel=Yes, and use connector-less ig-platform-id=0x01620007. Or, 2. Change SMBIOS model type to iMacPro1,1. But you will get green glitches in the H.264 output. Or, 3. Keep your SMBIOS as-is and add boot flags: shikigva=32 and...

    NOT correct advice. WITHOUT the dummy kext, the RX4XX/RX5XX will not be utilised and you will only get Intel Quicksync/Software encode/decode which is fine and will work. BUT, that's the not the purpose of this thread here (which is to try and use the AMD GPU for encode/decode).

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    I am on MacOS 10.14.4. I enabled the IGPU connector-less (needed enable H.264 encode/decode WITHOUT green artefacts) I installed Dummy141.kext in EFI/Others (needed to enable HEVC encode/decode in RX580) I use SMBIOS iMac13,2 I have DSDT.aml and SSDT.aml (for CPU power management) For H.264...

    The green line shows that the IGPU is still active. Check your BIOS setting again.

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    OK the first screenshot with the Intel Power Gadget, shows that you have IGPU enabled (the green graph line). It also shows that the CPU is maxing out at 4.0GHZ. This implies that even though everything "works" and "perfect" for you, your system is using the CPU and IGPU to do the encoding (i.e...

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Again, without screenshots of your IGPU and dPGU loading, your screen shot does not show which GPU is doing the encode in FCPX. Why don't you provide those screenshots as well ?

    Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

    Those screenshots show that Premiere will do the h.264 encode but it does not show with which GPU. You need to run tools to show the loading the IGPU and the dGPU. (e.g. Intel Power gadget and Activity Monitor). If H.264 encode is truly being executed by the dGPU then, it's load & utilisation...
