We are fortunate on these forums that some people with deep knowledge and insight sometimes post here. It makes sense to listen to what they say.A few years ago the suggestion circulated that TBDRs suck with DX11 tesselation. One of the reasons was that anything relevant behaved more than bad on SGX GPU IP in the Sony Vita handheld. With the GPU being DX9L3 I wouldn't expect any tesselation to present anything better than seconds per frame on a GPU like that.
Now the discussion here is moving back and forth for Apple's SoC GPUs which are based on a PowerVR Series7 Plus GPU which despite the tesselation unit present or anything else is not more than DX10.x compliant (if memory serves well it might only be up to DX10.0) due to high precision values that they skipped in the ALUs, and here we are discussing whether A or B DX12 feature works well or not on a TBDR. No idea where Alborix A or B lies in capabilities, but I wouldn't be surprised if their baseline starts with DX11.0 compliance and we don't have a single integrated unit yet from A series.
Considering he's been leading the GPU designs at IMG for at least two past decades I suggest he knows what he's talking about.
