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.

We've tested and benchmarked a handful of Tiger Lake laptops thus far each with integrated Intel Iris Xe graphics. Depending on the CPU, however, the number of shader units (EUs) will differ as shown below with higher-end models coming with more EUs:

Prior to GPU-Z 2.36.0, the program would report 96 EUs for many laptops with Tiger Lake-U CPUs no matter what processor they had. Our Lenovo Yoga 9i 14, for example, reportedly came equipped with 96 EUs even though it only had a Core i5-1135G7. Intel has confirmed with us that there are no Core i5-1135G7 CPUs out there with 96 EUs and that the numbers from GPU-Z had been incorrect.

Consequently, early online reviews of Tiger Lake laptops may have been posted with incorrect GPU-Z readings since the makers of GPU-Z didn't apply the fix until November 27th, 2020. We recommend checking the GPU-Z version used before trusting the numbers reported especially since fillrates are calculated with the number of active shader units present.

After graduating with a B.S. in environmental hydrodynamics from the University of California, I studied reactor physics to become licensed by the U.S. NRC to operate nuclear reactors. There's a striking level of appreciation you gain for everyday consumer electronics after working with modern nuclear reactivity systems astonishingly powered by computers from the 80s. When I'm not managing day-to-day activities and US review articles on Notebookcheck, you can catch me following the eSports scene and the latest gaming news.
