I recently picked up a new 16" Macbook Pro with 4GB Radeon Pro 5500M. The 5500M should perform very well, but because Apple has chosen to place a 50 watt limit on the card (AMD specifies 85 watts) it performs only a hair better than the 5300M. For example, in 3DMark Firestrike (popular PC benchmark) the 5500M gets a 10400 graphics score. In contrast, the 5300M averages 10300. Currently Wattman is not available for Navi mobile chips. MSI Afterburner is no help either. Are there any other utilities that can bump up the power? I know that it's possible because I was able to do it in Linux. I raised the power limit to 57 watts, and my Valley score (another benchmark available for Linux) went from about 1750 to around 1920, and confirmed the scores with multiple passes.
