Can you explain the low relative performance of the FPU in this  computer?  What difference does it make in day to day use?  It runs on CPU test at P11-350 but is 50% slower on the FPU test???  I have it clocked at 360, 4x90.  Other's may set it at 5x66 or 330. How does this affect perf.? Very stable machine, can you explain a little in these areas? Win98.  Thanks, Raisin

The low FPU marks will not affect your office apps. Floating-Point Unit calculation are mainly used for CAD and 3D games.  If you're not into these kind of things than K62 at 360 would be a fast machine for daily work.  Even if you intended to play some 3D games, you can still get a VoodooII add on card for it.

AMD is known for low FPU when compare to PII, Intel uses Pipelined FPU which is different than AMD in structure.  When releasing the K6-2 3DNow!, AMD added a instruction set to increase the performace of 3D games, but the game must support the 3DNow! in order to use it.  When 3DNow! does kick in, it runs in par with PII at same clock speed.

Rasin,
If you are running the CPU at 350 or more you might want to look at the following AMD webite for information regarding a patch:

I hope it helps.

Thanks for the FPU info, further in the question above, on performance, running at (4x)90 as opposed to (5x)66 and how this relates to the CPU (clocked at 95).  I guess these are bus speeds??  I am running a Banshee and it is very fast.  Thanks.

By increasing the bus speed on the AMD, you won't see as much benefit as you would see on the Intel chips.  Since the L2 cache is on the motherboard rather than build into the chip, but as always, running at higher clock speed will speed things up.  As I recall, the 90 settings default everything's bus speed except the CPU, so you're actually not overclocking other components therefore your Banshee is fine.  I think you AMD 333 can go further than 360, if you want to try, you can take it higher step by step.  I would go for 4X100 if you have PC100 memory.
