Curious. Why do you guys insist on using these (amateur-ish) tools, anyways?
Without doubt, THE most accurate data on your UHD/Iris graphics is found inside the respective "Architecture Whitepaper", courtesy of Intel - and ONLY there. Take a screenshot and crop? Typography's way better than W1zzard's :)
For AMD/NVIDIA, you can leverage their control panels, which will read special (diagnostic) registers via graphics driver and present you with the results. Clocks, sh. processors, API support, everything that matters and more. Dead accurate!
I too use these TPU-maintained "databases" all the time, they're cute as hell - but they're pure speculation. We've all seen how poorly they handle real world cards (like Radeon HD 8xx0M reporting "-32768 MHz clock speed").
Professionals have been HARD @ work. Give 'em a chance in 2021. Cheers!
