Tiger Lake + Renoir On Ubuntu Linux For Battery vs. AC Performance

Next up is looking at the time needed to convert twenty documents in LibreOffice over to PDF... The Tiger Lake performance was the same while the Ryzen 5 4500U was three seconds slower across that span of 20 documents, so assuming you aren't doing any batch processing though you are unlikely to notice the difference.

The CPU peak frequency was indeed lower on the 4500U with battery.

The clocking behavior of the Ryzen 5 4500U on battery did lead to a lower temperature.

The Darktable RAW photography software did also reveal slightly longer operations for the Renoir laptop when on battery power.

Likewise, the GIMP imaging program was also taking longer for some of its imaging work on the tested Renoir laptop while operating on battery.

But when it came to the multi-threaded RawTherapee program, there wasn't as much of a performance difference between AC and battery power sources. The Ryzen 5 4500U regardless of power source was outperforming the Core i7 1165G7 as well thanks to its six Zen 2 CPU cores.
