Scary numbers from the slot CPU era:

for volt and amps values.

PS; The table doesn’t include the latest Sempr0n (Socket A), Barton 400FSB (Socket A), Geode NX (Socket A), Thornton (Socket A), 130nm CG stepping K8 and 90nm D0 stepping K8s,

VIA's early Cyrix III (Joshua, Jedi, Gobi) was based on native x86 Cayenne core. In was later dropped in 2000 in favor of Centaur's WinChip/C5/Samuel. After employing Samuel core, VIA was still using Cyrix III label but this was shorten to just 'C3'. The C3 that I’m referring to is the x86 Cayenne core.

National's Cyrix group(before the buyout by VIA in 1999)has Cyrix MIII (M3, Jalapeno core, Mojave),
It's was an out-of-order, decoupled design (translate x86 to uops) and it has 11 stages.

The usage of "and VIA’s C3(from Cyrix M3 core) is based from Cyrix" statement is for Kenny’s performance/power ratio.

KennyR’s statement about Cyrix PR200’s performance/power ratios can be easly reach by today’s VIA C3 MPU. Using Cyrix PR200 as an example of performance/power ratio reference would be considered to be very poor in the light of AMD's Geode NX/16Watt&35Watt grades K7-AXPs, Intel's Pentium M and VIA's C3(Nehemiah).

Depends on your radeon. If you buy a gamer's radeon, then you're asking for it. But there are better ones. My 9000 has no fan at all: its passively cooled. Along with the fanless G3, and fanless case, it means my Pegasos is absolutely silent except for the PSU. Now, if only I could get a x86 system like that, even if it was seriously underpowered by modern standards!

You have search for an X86 motherboard that can under-clock and under-volt. Most modern Taiwanese K7-XP boards can over-clock an Athlon XP(only with t-bred/barton cores) and same can be true if one wants to under-clocks them.
