UPDATE: ARM has now removed the post in question and has stressed that it was not an official statement.
Exactly why a component supplier for Nvidia is posting spec details if it's not entirely sure they are correct is anyone's guess, but for the time being it would seem that the Switch's core tech remains unconfirmed.
ORIGINAL STORY: Ever since reports began to circulate that Nintendo and Nvidia were working together on a new console there has been rampant speculation about exactly what kind of chipset would be doing the heavy lifting.
When Eurogamer published its report last year, it was optimistically assumed that Nvidia would be supplying its latest Tegra offering to Nintendo - perhaps based on its new Pascal architecture - and not the existing Tegra X1, which had already been seen in the Nvidia Shield Android TV unit, released in 2015.
Eurogamer has since unearthed more information which suggests that X1 is indeed the chip being used, and now ARM - which supplies the Cortex CPUs used in Nvidia's chipsets - has apparently confirmed these reports:
In case you didn't know, Tegra X1 also has four Cortex-A57 cores, each running at 2GHz. For comparison's sake, Nvidia's next generation chipset - the Pascal-based Tegra P1 - features two Denver2 cores in addition to four Cortex-A57 cores.
While it's highly likely that the silicon inside the Switch features some customizations over the basic X1, it's clear that it is built on what has gone before, rather than being a totally new offering.
This might not be totally surprising news given the reports we've already seen, but it's as close to official confirmation as we've had so far of exactly what's powering Nintendo's new console.
