NVIDIA has recently introduced its 3000 series of Ampere graphics cards designed for mobile/laptop devices. And usually, these GPUs in the past few years have been divided into two configurations: Max-P and Max-Q. The Max-P variant was a maximum performance configuration meant for more power usage and higher temperatures, representing a standard GPU configuration. The Max-Q design was, according to NVIDIA, "a system-wide approach to deliver high performance in thin and light gaming laptops. Every aspect of the laptop, chip, software, PCB design, power delivery, and thermals, are optimized for power and performance." Meaning that the Max-Q variants are more TGP limited compared to the Max-P configuration.
Update 23rd of January 11:35 UTC: NVIDIA spokesperson
told Tom's Hardware that: "No, Max-Q branding is not going away. When we originally introduced Max-Q back in 2017, the brand was initially used in GPU naming since Max-Q referred to the GPU TGP only. Today, 3rd Generation Max-Q is broader, and is a holistic set of platform technologies and design approach to building powerful and thin laptops. In addition, to be more transparent about a laptop's exact capabilities, RTX 30 Series laptops now show more information than ever, listing exact TGP, clocks and features supported. You will find this in the control panel which now reports maximum power (TGP+Boost), and support for key features including Dynamic Boost 2, WhisperMode 2, Advanced Optimus, and others, all of which fall under the Max-Q umbrella. We strongly encourage OEMs to list clocks and other technologies a laptop supports, including Advanced Optimus, Dynamic Boost 2, and more. Ultimately, like all laptop features and specs, it is up to the OEM to market what their particular laptop configuration supports.)"
