I didn’t see anywhere in the article which codec was used for the AMD card and what settings. VCE is very fast on my machine but I can only say that for VP15.

I read the article. bob-h's claim is totally misleading.

AMD cards 70% slower than Nvidia cards in VP16

    IS NOT  TRUE.

Read the WHOLE article.

A few things that are not mentioned. I am more interested in seeing benchmark on Vegas time line performance on 4K single and multi tracks. Rendering AMD VCE vs NVENC that is what I want to see. At the movement I believed AMD VCE are far more faster then NVENC in rendering. Looking at many of the old threads are complaints after complaints why their NVENC GTX1080 ti are performed poor vs AMD Vega 10 Frontier Edition card. are not working or not fast in rendering fast in Vegas. I personally have not seen any GTX 1080 or 2080 out perform Vegas 10 Frontier Edition Card, specifically in Vegas Pro.

Which exact cards are you referring to?

When you look at the yellow graph lines, all the amd cards shown do the 'aircraft takeoff' HEVC render (stabilize,color corrector) in around 175 seconds, while all of the Nvidia cards of QuadroP4000 & higher do the same render in 100-110 seconds. For people unfamiliar with Quadro cards (such as myself) I think P4000 is about equal to GTX1070 consumer card for non 3d video render work.

Also, there is the possibility this is an error by the tester if people aren't seeing this slow down with vegas color corrector in vp16

In my world 175 seconds is 37-43% slower than 100-110 seconds. But I accept that this phraseology is open to interpretation.

Anyway this test does not have much value for comparing NVIDIA vs AMD without at least knowing what encode mode was set in the render settings.

Circumstantial evidence points to him using 2m30s 4k60p h264 AVC video utalising a 4k60P project using 2 plugins - 'color corrector' & stablize, rendering to 4k60p HEVC. Not known if he used NVENC/VCE HEVC or software HEVC. Cpu Intel i9-7980XE.

My cpu is not fast enough to verify any results.

Hi all. I am the one who authored the review. I've chimed in here before, saying that I'd improve the tests in the future, but I haven't been able to do that with so much going on. I am definitely keen on improving the tests I have. In time, I'd even like to add things like playback tests, but again, I'm dealing with too many suites and so many tests, so it's hard to get on top of everything. 

For settings, I used NVENC for NVIDIA and VCE for AMD. The Taipei project was AVC, and the Aircraft one was HEVC; the codec differences might be the key here. I apparently updated the graph after it was shared here to reflect the codecs. Both are 4K to 1080p/60. On that note, does Vegas have a feature similar to Premiere Pro's Maximum Resize Quality? That might help use GPU better. Maybe...

Right now, I am limited to doing simple encode type tests, but I want to improve those to become more realistic (if anyone wants to share screenshots or anything of completed projects with filters, please feel free - I benchmark with dozens of apps, and I am not really a master at any of them.)

I know my results do not add a ton of value right now, but I am definitely planning to beef them up and make them as relevant as possible (since that's the entire point).
