Inspired by a question I saw on reddit earlier today, I decided to repurpose some slides initially created for a press briefing earlier this month.
The images below show you how the three individual MIPS CPU families (i.e. microarchitectures) evolved over time, starting with the Classic lineup released in the early 2000s all the way to the Warrior generation introduced in 2013.
When it comes to the MIPS architecture, the two diagrams below offer you a quick visual interpretation of its history. The 32-bit strain started in 1985 with MIPS I, which gradually morphed into what is now known as MIPS32.
On the 64-bit side, MIPS III was announced in 1991 as the first licensable 64-bit RISC architecture to ship in a commercial product; over time, MIPS III grew into the MIPS64 ISA.
