Nintendo Switch Uses Nvidia Tegra X1 SoC, Clock Speeds Outed

The Nintendo Switch -- the hybrid portable games console/tablet due for release in March 2017 -- will be powered by Nvidia's older Tegra X1 SoC and not its upcoming Tegra X2 "Parker" SoC as initially rumored. From a report on ArsTechnica: The use of Tegra X1, which also powers the Nvidia Shield Android TV, means the graphics hardware inside the Switch is based on Nvidia's older second-generation Maxwell architecture, rather than the latest Pascal architecture. While the two architectures share a very similar design, the Switch will miss out on some of the smaller performance improvements made in Pascal. When docked, the Switch's GPU runs at a 768MHz, already lower than the 1GHz of the Shield Android TV. When used as a portable, the Switch downclocks the GPU to 307.2MHz -- just 40 percent of the clock speed when docked. Given the Switch is highly likely to use a 720p screen rather than 1080p -- this is currently assumed to be a 6.2-inch IPS LCD with 10-point multi-touch support -- there is some overhead to run games at 1080p when docked. However, it's questionable how many developers will go to the effort of creating games that make use of the extra horsepower when docked, rather than simply opting to program for the slower overall GPU clock speed. While GPU performance is variable, the rest of the Switch's specs remain static. Its four ARM A57 CPU cores are purported to run at 1020MHz regardless of whether the console is docked or undocked, while the memory controller can run at either 1600MHz or 1331MHz in either mode.
