Mere days away from the Nintendo Switch's launch, elements of uncertainty still surround the final technical specifications for the new console - but a massive leak of Nintendo's developer documentation, along with a teardown of retail hardware by a Chinese parts firm may well have given the game away. Meanwhile, new information we've sourced reveals final tweaks Nintendo has made to hardware performance in the run-up to the console's release.
[...] However, there is some interesting news. While the main clock configurations for docked and undocked modes remain the same, Nintendo has added to the available performance modes available to developers in a recent update. However, we're looking at a bump to mobile GPU power
[...] The expanded table above still shows memory frequencies in line with Tegra X1's capabilities
and a look at the Chinese Switch teardown shows two Samsung LPDDR4 modules in parallel, in exactly the same configuration used in Shield Android TV. The only difference seems to come from the capacity of the RAM chips. Shield uses two 1.5GB modules, while Switch ups that to a 2x 2GB configuration for 4GB of total system memory. [...] The precise parts are still unconfirmed but the configuration strongly suggests a 64-bit memory bus
, again tying in with the existing Switch spec leaks and ruling out the 128-bit interface used with the Pascal-based 16nm Tegra X2.
[...] While there is still the possibility of a more refined SoC within the retail hardware, the bottom line is that Switch has a processor that looks like a Tegra X1, with specs from Nintendo in line with X1, and power consumption that fits the characteristics of the chip's 20nm fabrication process (and power draw analysis of the second Shield revision may prove illuminating as a closer comparison point). To what extent Nintendo and Nvidia have customised the technology remains unknown - but major revisions to the hardware would almost certainly have resulted in a noticeable change in dimensions for the final silicon compared to Tegra X1, something that isn't apparent on the Switch SoC.
