With such a selection of P4 proccessors on the market and a new range due out in September ( so I'm told ) I need some advice! How would a P4 2.4GHz with hyperthreading & 800 front side bus compare to a P4 2.4GHz with no hy/th & 533 fsb?
the former will be quite a lot faster overall particlarly when running more than one intensive task simultaneously. the processor chews at the same speed but you can shove a whole load more in its mouth at once.
Which of the new 800MHz FSB CPUs would be closest to the 3.06GHz CPU?
So much depends on motherboard, memory used and so on, but to cut through that, as a rough idea, I should imagine the new 2.8GHz will be closest overall. It can probably beat the 3.06 on some tests, but will lose on tasks requiring sheer CPU clock speed (such as MP3, video encoding). The new 2.6GHz should be behind the 3.06GHz, but probably not by too much.
Depending on what the price difference is, you may find 2.6 the best deal, although the 2.8 should not be a bad deal either.
