AMD Grabs Some of NVIDIA’s Add-in GPU Marketshare

I was just reading VizWorld and noticed a reference to an article summarizing a JPR industry report with the following:
“The quarter was the first where AMD finally started to gain back some share from NVIDIA. JPR reports that AMD’s unit share rose from 31% in Q1 to 35% in Q2 with NVIDIA seeing their share decline the same 4% to 64% overall. That means that AMD took every bit of its growth from NVIDIA’s marketshare.”

Would have love to have seen this comparison specifically for the professional markets.
