I'm not sure that's really the sort of architectural change that was intended. It's not fundamentally altering the chips in a way that makes them more powerful, just packing more in the system to raise its overall capabilities. It's like claiming you had found a new way to make a bulletproof vest twice as effective, by doubling the thickness of the material, when I think the original comment is talking about something more akin to something like finding a new base material or altering the weave/physical construction to make it weigh less, while providing the same stopping power, which is quite a different challenge.

Snigger is just a variant form more common in the UK, where snicker is the preferred one in the US. Though I wouldn't put it past a 4chan user, it's also a perfectly normal word they may have learned being taught and exposed to UK variants of English.
