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.
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.
