Deschutes performance

  Take a Deschutes Pentium II 450 MHZ CPU on a generic 100MHZ FSB BX Motherboard, what percentage faster is it than the 400 MHZ version on the same Motherboard? A rough percentage is all I ask, I need to know if the 450 is worth the extra $$.  Also, I assume the 450 version has the motherboard clock multiplyer set to x4.5?

First, no! For now, a 450 MHz processor isn't worth the extra $$.
However, it depends on what you want to do. When you are using applications doing lots of calculations, and processing nearly no data, you can in the best situation gain 3% of speed.
Note it is not only the performance of the processor making your system speed, it is also the chipset on the motherboard, the VGA card, the amount and type of RAM, the speed of your harddisk etc.
For both 400 and 450 MHz system, those elements remain the same! That's why you cannot say that a 450MHz system is 12% faster.
For normal apps, you can gain 1% to 2% of speed maximum.
You invest in a 100 MHZ board, a good thing to do.
The amount of RAM is important. 64MB is needed for good performance.
Also look for your harddisk to be a fast one. You better invest a bit more in a fast harddisk instead of in a 450 MHz processor.
Ultra ATA is a must-have.

Further, most motherboards haven't got a multiplyer factor in jumpersettings anymore. They read it directly from your processor.
If you have jumpers, busspeed has to be set to 100 MHz, multiplyer has to be set to 4.5X as you mentioned.

Good luck and remember, the processor in a system is just one element. It is like buying a Porche with small tyres. You won't win the race.
A fast harddisk, a sufficient amount of RAM (ECC DRAM!), a good AGP VGA card and a good brand of mainboard (Asus) are as important as the processor itself!

Thanks engeltje,
                 Thats a good answer, yeah I suspected the 450 was only slightly faster but needed another opinion. I'm looking at the ASUS P2b at the moment with, yes, 64 MB of PC100 RAM. This machine will be specifically used for calculating as it go's thru arrays of data using what amount to for/next loops in an AI application using little disk access and no real-time graphics, I wonder if you could frame the P II 450 vs 400 debate in terms of that kind of usage. Not exactly a 'normal app'.  Thanks.
