It is but you can try non FF TU7/fastest preset where you can use 16 bframes+bpyramid, it's fast and the quality is better than TU1/best FF no bframes+bpyramid according to my tests. Same video from #379: TU7 16 bframes+pyramid PSNR-Y: 29.45---3337 kbit---116 fps TU1 FF no bframes/pyramid PSNR-Y: 28.95---3432 kbit---81 fps |

No it won't be the same unfortunately, HD630 is Gen9.5 based which is old gen. Intel upgraded their HEVC encoder with Icelake (Gen11): https://forum.doom9.org/showpost.php...&postcount=317 With Tigerlake there is another upgrade to the HEVC FF encoder (bframes+bpyramid support). |

Desktop CPU generation called Rocketlake-S is coming this month with Xe based iGPU, the desktop models have only 32 EUs instead of 96, even though the media capabilities should be the same. Also there are some NUC devices in the market based on Tigerlake-U. |

Intel H410 and B460 will not be compatible with Intel Gen 11 CPU, it's a shame. |

Another test. I'm using ToS_1920x800_xdither from this thread and a low bitrate of ~1 Mbit with max 120 gop (Quicksync 121, Intel recommended 5*fps+1 for Quicksync some years ago)
Code:
VMAF speed bitrate Quicksync H265 (27.20.100.9316) HD630 CQP 86.78 52 fps 1023 kbit Iris Xe CQP FF best 90.04 344 fps 1028 kbit Iris Xe CQP best 90.55 97 fps 1014 kbit NVENC H265 (461.81) GTX1080 CQP best 85.86 215 fps 1023 kbit x265 (Staxrip 2.1.8.4) i7-1165G7 ultrafast 87.23 81 fps 1017 kbit i7-1165G7 ultrafast CRF 84.80 83 fps 1023 Kbit i7-1165G7 ultrafast QP 83.90 83 fps 1001 Kbit i7-1165G7 medium 90.13 28.5 fps 1013 Kbit i7-1165G7 slow 92.47 10.7 fps 1014 Kbit I did us CQP 27_27_29 offset 2_3_7 bframes 16 for Iris Xe if someone is curious, same on HD 630 except for the CQP parameter.

I'm using this this sample with a bitrate between 18.0-18.8 Mbit and 10 bit. All of them have a good quality with this high bitrate, a faster Quicksync preset makes sense in this case. I think I could even try fastest FF.
Code:
VMAF speed bitrate Quicksync H265 (27.20.100.9316) HD630 CQP 97.45 15 fps 18.5 Mbit Iris Xe CQP FF best 98.33 67 fps 18.8 Mbit Iris Xe CQP fastest 98.09 107 fps 18.2 Mbit Iris Xe CQP best 98.46 29.5 fps 18.7 Mbit NVENC H265 (465.51) GTX1080 CQP best 96.43 87 fps 18.0 Mbit x265 (Staxrip 2.1.8.4) i7-1165G7 medium 97.70 4.8 fps 18.4 Mbit i7-1165G7 slow 98.44 2.1 fps 18.5 Mbit Last edited by Yups; 13th March 2021 at 21:11. |

Iris Xe really holds up against software encoding, at least in metrics. Do you see any visual differences between Iris Xe best and x265 slow? NVENC tends to remove details to get better compression for the image as a whole. Could you upload the encoded clips?
