genuine pentium or celeron?

Are celeron processors much slower than the regular pentiums? I'm told that they're not really all that much different. Something about the pipeline in regular pentiums being much bigger than need be and the pipeline in celerons being just a bit smaller?

It's been a while since I've checked, but...

A Celeron used to be nothing more than a normal Pentium with the L2 cache removed or reduced.

Intel used to make one processor, then market it ( with different clock speeds / cache ) as a number of different processors. They probably still do - which is why Pentiums are usually stable when overclocking.

So yeah, a Celeron is a "starved" Pentium.

For more info have a look at the review section of - they'll probably have one specific to the processor you're considering.

The speed of a processor is determined by the speed of the motherboard, and a multiplier at the socket. A Celeron runs on a slightly slower motherboard setting. A P!!! would run on a 133MHz motherboard whereas a Celeron would run on a 100MHz. You then multiplier that by the multiplier to get to the actual chip speed.

A Celeron also has a smaller on-chip cache. There is s a little bit of memory on the processor, which is much faster than the system memory. That is the cache. A P!!! can store more data on the processor cache, and doesn't need to call to the system memory as often.

Other than that, the processors are the same. That is why people used to buy a Celeron and overclock it on a 133MHz motherboard to get nearly the same performance as a P!!! for a fraction of the price.

The less L2 cache still makes a significant difference.
