Going from a PI (not two) 233MMX CPU to a PIII 500MHz CPU was about a 3 times
increase in render speed for me.  Maybe that's comparable in some way to your
upgrade idea, so say about 2.5 times?  I don't think the cache is going to be
all that important unless you count minutes or seconds or something.  Mine went
from 256KB to 512KB; although I haven't seen anything on performance
benchmarking of one amount of cache to another so I really don't know.
Actually the biggest performance hit might be in keeping the old mainboard if
it's got a 66MHz or 75MHz bus instead of 100MHz for example.  That and HD too.
You might reconsider and get a 100MHz bus mainboard and matching Celeron
instead(?).  I just saw a web page about them but can't locate any.  I didn't
see any mention about such a thing at Intel:
http://www.intel.com/design/celeron/index.htm

If you were asking if the Celeron 433 might be better (?, you wouldn't want 80%,
180% yes, 100% is equal) than with the PIII 333 I'd guess it would be close
enough for price to matter a whole lot.  But there's that motherboard thing
about it all,  memory as well, to sync up all the parts.

| Dear all,
|
|   I am planning on upgrading my Pentium II 233MHz(512K cache) to Celeron
| 433MHz(128K cache).  Motherboard, RAM, and all other hardwares will be
| the same.
| I might not upgrade my motherboard yet. The current motherboard can
| accept upto Pentium II 333MHz(512K cache) or the Celeron 433MHz.
| Would the Celeron 433 give me performance boost of about 80% or more,
| even though the cache size has been reduced, in terms of POV-ray
| raytracing?
| Any comment would be welcome.
|    Thanks in advance,
