68080 is an affordable processor for your Amiga that is way faster than the fastest 68060. It is 100% code compatible with all CPUs and FPUs of the Motorola 68000 family.
It is a new processor you can code as easy as any previous Motorola 68K CPU. 68080 can execute all the instructions of the 68k processors before it, as well as brand new instructions which offer enhanced performance and features no other 68k can!
68080 is a CPU with very large number of instructions. This might sound complicated, but in fact it is flexible, because you have instructions for very different use cases. Not every program you write is the same and many programs you can write as a sub set of instructions, you do not always need to use all those different instructions, but sometimes you want to do something special.
Advanced CPU design - the 68080 is the most advanced 68k processor available today. Why(C)Because it is designed with features found in the latest CPUs from Intel or AMD. The 68080 is super scalar, hyperthreadiong and supports dual pipelines, as well as offering twice as many address registers and 4x times as many data registers as any other existing 68k processor.
Compatible, while also breaking new ground - the 68080 can execute all the instructions of the 68k processors before it, as well brand new instructions which offer enhanced performance and features no other 68k can.
Modern, redesigned MMU - the MMU in the 68080 is completey redesigned, so offers new and enhanced features compared to all preceding 68k CPUs.
The 68080 is the fastest, most advanced and compatible 68k CPU available.
