Hi folks,

I was trying to research what kind of footprint a hardware de- and encoders roughly have but didn't find very much.
Wikipedia talks about one old AMD decoder for H.264 and VC-1 being "4.7 mm˛ in area on 65 nm fabrication" and one paper about a H.264 decoder design talked about being 430k transistors, but that is all I found.
Was there ever any chip die-shot analysis showing how large a modern video block really is?

Thanks for your help

An editor at Techspot.com has been kind enough to identify the codec area on AMD 6800XT and Nvidia 3080
