With everyone heavily anticipating the Nintendo Switch 2, we expect it to launch anytime soon. Previous rumors said that the Switch 2 would use an NVIDIA Tegra T239 processor, but there’s more to the story: according to Moore’s Law is Dead, the Nintendo Switch 2 nearly used an AMD chip, but the latter lost the bid due to the power and efficiency of its chip design at 5 watts.

While that’s strange that Nintendo chose to stick with NVIDIA–considering the majority of gaming handhelds are powered by AMD chips–the reason behind the decision is that Nintendo was looking at the best performance at 15w TDP. Nintendo didn’t want to go for a higher TDP like other gaming handhelds, as this would result in using a bigger battery to get a good runtime while unplugged.

Aside from concerns about power efficiency, costing played a factor: according to Moore’s Law is Dead, NVIDIA’s chip has a lower cost compared to what AMD has to offer for the Switch 2. As for other rumors, the Switch 2 is expected to have 12GB RAM and a 20wH battery–and Nintendo’s focus on a lower TDP means that the battery life on the Switch 2 will be more efficient when in handheld mode.

With Tokyo Game Show happening this week, we expect Nintendo to make an official unveiling of the Switch 2 to answer all the rumors about their much-awaited gaming handheld.
