If you jump to the original linked page you will see the render templates used, the post is a bit of the way down ... https://www.vegascreativesoftware.info/us/forum/intel-i9-9900k-processor-review-using-vegas-pro--113429/?page=2

Extract from previous testing, see above link ...

Some “Red car” benchmark tests with this cpu ...

Oveclocking in brackets (Overclocked). Defaults for all render templates, 24/12 etc. see below. All output is FHD.

[ non OC 4790k values]

HW Acceleration = Nvidia

Render with Nvenc .......  0:21s …..... [4790K ... 0:31s] .... (19s) … Hevc is 0:23s {(20s)} [444 (19s)]

Render with QSV ..........  0:18s ……………………………. (15s) … [444 (44s)]

Render with Cpu only ...  0:59s ......………………………... (53s .. 70 deg) .. [444 (53s)] ...[4790K ... 2:11s]

HW Acceleration = Intel Graphics

Render with Nvenc … N/A ….......  (34s)

Render with QSV … N/A ..........  (48s)

Render with Cpu only … N/A ….  (54s .. peak cpu temp 67 degrees)

HW Acceleration = None

Render with Nvenc .......  1:10 ………………………………… (1:05s)… [444 (1:05s)]

Render with QSV ..........  1:05 ………………………………… (0:58s) … [444 (1:18ss)]

Render with Cpu only ...  1:33s ......…………………………… (1:35s .. 71 deg) .. [444 (1:31s)]..[4790K ... 3:08s]

Unfortunately no results for the middle Intel QSV section above, when I attempted to render, the time counter just kept moving up, no rendering, each time I had to do a forced PC shutdown.

Update … The new Intel graphics driver 444 fixed the middle section issue.  I've added in values post Intel driver update in brackets [444 ].  Note that the render times are now longer for QSV renders, more than double where rendering using QSV and Nvenc is HW Acc.  Non QSV render types are the same or slightly quicker.

N/A  …  Simply no tests done here for non Oveclock
