speed?

what is the speed of pentium 4 processor?

what is selron processor all about and is it good?

[He-M@n]

Does that question concerne API or VB or something like that?
I think thats a harware question and not software!

As far as I know the speed of P4 is available from 1Ghz to 1.4 GHz. The "Celeron" processor has less internal cache memory (128 kB) than the normal pentiums which have around 512 kB. The cache memory greatly affects the processing speed even if you use a celeron of 800MHz and a P3 of 800Mhz. The speed of P3 will be obviously faster than Celeron due to cache.
I advice you not to go for Celeron unless your budget is too tight.

clarification:
Pentium 4, ranges from 1.3Ghz - 1.5Ghz currently, they're going to release a 1.7Ghz part by the end of the month. the P4 is slower than an Athlon at the same Mhz or Ghz if you prefer, and in most cases the 1.5Ghz P4 is slower than a 1Ghz P3...The reason for this is because the Pentium 4 doubled the pipeline to 20 stages from the Pentium 3...one may think well, the more stages in the pipeline the better, but just remember the more stages, the more penalty for a branch misprediction...anyway, the p4 only can be used wit RDRAM and quite honestly if you ask any knowledgable computer person, the P4 is just not worth it....Nobody's going to recompile all the x86 code out there to take advantage of the P4's humungous 20stage pipeline.

as for Celeron, not selron, there are the older ones and the newer ones, the newer ones are fcpga (flip chip) and have 128k full speed on die cache, these are basically crippled PentiumIIIs with half the cache and associativity...i think the new celerons have 4 way associativity and the pentium IIIs have 8 way...the new celerons also have all the features of the Pentium III, the older celerons have the features of the PentiumII. Is the celeron "good?" you ask, well depends on your definition of good...if you're running office then yeah, an 800mhz celeron with the 100mhz bus is "good" but if you're rendering images for professional quality purposes, then no, stay away
