Version 2.36.0 fixes the issue, but it wasn't released until weeks after we had our hands on the first Tiger Lake retail laptops. Be sure to update to the latest version or else the number of EUs and potentially fillrate speeds may not be reported correctly.

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!
