Ok, so shall we take a vote or what?
I am not a hardware type but the R4200 seems to be enough for me it and it
eats 486/66 raw even as it is (here is the table again:
Vendor Clock Chip Price SPECint92 SPECfp92
unspecified 100 R4000SC 640 61.7 63.4
unspecified 150 R4400SC 1120 88(est) 97(est)
NEC 80 R4200 70 55 30
^^
And, for comparison
Intel 66 486 542 32.2 16.1
^^^^
Intel 66 Pentium 965 64.5 56.9
)
and the Pentium is out of the question price-wise as far as I'm concerned,
not to mention that going for it must mean waiting for another year at least.
Especially when you take the price/performance and at what price do we want
the system to end up with, I vote for the R4200 and let's go on with the rest
of the design.
Only one question (not that it is going to change my view): you mention
a possibility of a separate FPU. Is it possible to leave space for a socket
for it a-la the 386/387 combo? (again, I'm not a hardware type so please
bear with me if this is a stupid question).
I hope I'm doing the right thing but I propose that others on the list who
kept quite so far (like me) and followed the discussion for the last couple
of weeks will let us all know what they think (is there an echo out here ? :).
Maybe the "core" of this list should appruve of this before things get out
of hand, ok?
