Contrast this with the PS5, which launched in 2020 with an AMD Zen 2 CPU which launched in 2019.
If you care about tech specs, consoles are a losing battle. Even if they are a good price-performance when they release, the length of console cycles will inevitably cause them to be underpowered and outdated by the second half of their existence, and yet many great and generation defining games come out closer to the end of a console's life cycle.
In what sense did the X1 cpu launch in 2012?
i.e. The X1 is a chip which contains lots of stuff including some processors from 2012.
It's just sad that the switch has become long in the tooth. Great for many, but now limiting. The problem is that Nintendo has tried and failed to succeed with spec bump consoles (see, the new Nintendo DS and the new Nintendo 3DS), so the fact that they haven't followed up the Switch with a spec bump makes gobs of sense.
While processor speed may have withered, there were other innovative and cutting edge aspects of the design.
It was innovative and a great product, but I'm not sure anything in it was cutting-edge from a technology perspective.
Something doesn't have to be cutting-edge though to be innovative, fun, well designed and a great product.
This is the 'withered technologies' playbook in action - use underpowered/mature technology in new and fun ways rather than relying on cutting-edge graphics technologies. As an example when the switch was launched in 2017 the processor inside it was a standard processor from 2 year prior.
Nothing in the Wii was cutting edge in terms of the technology - it was just well implemented. The motion controls were 2 IR dots and a cheap camera, and that wasn't a new concept.
Similarly nothing in the switch was actually cutting edge technologically, just assembled into a great product.
