Hmm I don't know about the merced, but from the specs I saw for the psx2 system, it has less registers (erm from what I remember 32 general regs, I assume the fp regs are similar), vs. the merced's 128 regs set (if I remember rightly). The caching on the psx2 was fairly unimpressive too, it had a 8k/16k instruction/data cache and 16k scratchpad mem, no mention was made of any other forms of caching. Considering that the current low end pentium class chips have much more caching, I do not doubt that the merced processors will have better caching. If those specs are roughly right (I'm doing this from memory..) I would expect the merced to out perform the psx2's cpu in real world work. Actually from looking at the specs of the psx2 I would guess that the complete system will perform as well as a tnt equipped celeron 400, but that is just a guess.
