I remember the "bit wars" of the late 1980s and early 1990s. The Genesis/Mega Drive and the Turbografx-16 were heavily marketed as having twice as many "bits" as old-school Famicoms and such. A few years later, Atari returned with its monstrous "64 bit"!!1!11one Jaguar system which was pwned by the Nintendo 64 and Sony PlayStation.
Starting around 2000, word size seems to have faded out of the world of gaming marketing and criticism. It became all about having wowie-zowie immersive 3D graphics, raw bit count be damned. Without a spec sheet, I couldn't tell you how many bits a PlayStation 2, Xbox 360, or 3DS has, nor have I cared enough to check before buying one.
So, my question is, how high has word size actually gone in terms of gaming consoles? Was there ever a 128-bit console? 256? 512? 1024? How about a 2048-bit monstrosity? If I am dreaming of creating the world's first 4096-bit Mega Word Pwnage Rhinocerous9000 XL 2022, would that be a record or would I just be an also-ran in the lost Bit Wars?
To be clear, I'm not asking for a definition of or explanation of word size. I'm asking a historical question. I'm also not asking why word size is no longer prominent in marketing, but more interested in whether bit size continued to grow behind the scenes or whether "more bits" is pretty much dead in terms of gaming. In other words, does the fading out of reference to bits in game console advertising represent a technological stagnation in word size growth (i.e. we are still playing on 32 and/or 64 bit machines 20+ years after they became standard), or did word size continue to grow on the technical side but was no longer emphasized for marketing purposes?
