Hi,

just upgrade from p4 celeron 2ghz to p4 2.26b. In direct compare between
these 2 cpus, how many times is 2.26b faster than a 2ghz celeron ?

512K versus 128K. Eight way as opposed to two way cache sectoring, and yes, a higher FSB, 400 vs 533. I have the same chip and it's great. I got mine to 2.90GHz with a 685MHz FSB completely stable (P95 for 18HRS+), paired with 2x256 Dual Channel PC4000 DDR @ 446MHz CAS 2.5-3-2-5. This system is absolutely smoking. You should try to OC it some time. ;) Even if you don't, a 2.26 is one helluva lot faster than a 2GHz Celeron.

The P4 architecture relies on a large cache owing to it's long pipeline. With the small cache of the Celeron, a mis-predicted branch can mean a pipeline stall, which kills performance. A 2.8GHz Celeron is about the same performance as an 1800+ Athlon if I remember that article correctly.

ive always wondered about the speed diff between a p4 and a celeron as well (provided the same clockspeed and fsb)

Well in Quake 3, a 2GHz Celeron was getting 150 FPS, wheras the real P4 was on 250FPS. Theres a set of old benchmarks here
