Dreamcast was the only 128 bit system that gen, believe it or not.
GameCube and PS2 had 64 bit chips.
Xbox had a 32 bit chip.
The N64 was 64 bit capable; but it was never utilized, the data operations were 32 bit for all games. The console was bottlenecked in several areas, and was an absolute nightmare to develop for.

When people say 128bit they don't mean the chips they mean performance wise, PS2 had a 64bit chip with a double core, hence why the EE is called the 128bit emotion engine while the GC had a similar style set up with a faster processor, the DC chip itself was a 64bit double core.

When people say 128 bit they can only mean that it has a word size of 128 bits. You can't talk about two 64 bit processors being 128 bits. It'd be like saying that two cars are a truck.
The 128 bit being referred to in both the DC and the PS2 is the vector processing unit, not the architecture of the CPU.

Poor analogy at best, word size by the time of the 6th gen arrived was an ever decreasing factor hence why bits stopped being acknowledged, you can say a double core 64bit chip equals that when the tech has the processor speed to utilize it to the performance level of 128bit which is why that whole era is know as the 128bit era performance across the board was pretty much even, Sony and Sega were the only ones who used the 128bit in marketing even though their chips were double core 64bit chips.

They were either lying (or as we call it 'marketing') or referring to the vector processor. Two 64 bit processors is in no way equivalent to a 128 bit processor, it really is the equivalent to two cars being a bus. 128 bit processor has a much longer word length which increases address space, data parellelism and floating point precision. Multiple cores allows seperate threads to be run simultaneously.
They do not have equivalent effects on performance at all - it really is apples to oranges.
