Hey guys i need some help in buying a new cpu but i dont understand all the new cpu's that are out

i have atm a p4 478 prescott 2.8ghz which is not doing a good job any more.

this is the entry level duo i could see off Intel Core 2 DUO E6300 "LGA775 Allendale" 1.86GHz

does that mean the duo has the combined speed of 3.72ghz? if so does this mean im only getting a performance increase of 0.92ghz or am i barking up the wrong tree lol?

Please help this poor noob out :)
 
u are barking up the wrong tree that conroe will kick that 478 P4s ass m8 the clock speed mught seem slow but it really isnt, i would say the E6300 is on par if not better than an AMD A64 X2 4800, ask anyone they will say the same thing
 
Small dog big tree. Perfomance wise huge difference. You have two cores running at 1.86ghz each and one of the cores would probably out perform your current processor.
 
Aye, the Core 2 architecture can do A LOT more than a Pentium 4, P4 was built on clock speed really, Core 2 is built on efficiency.

The dual core doesn't mean you can multiply the clock speed together and have an equivalent processor, you'll get a fair size increase in applications that support it and a medicore one in those that don't but even in single core apps the other core will help take some load off.

Compared to your P4 even the cheapest Core 2 Duo will be a massive increase.
 
how can u rate a core duo if they dropped the mhz rating?

what speed is a e6300 if u was to give a mhz equivalent? is it like what Massive Attack said a 4800?
 
Would have said around an X2 4400+ myself but something like that yeah, the 4400+ is a performance rating too though, it is 2x 2.2 Ghz (1MB L2 cache) cores. It can't be directly compared with a P4 either, thinking of the performance as a 4.4 Ghz Pentium 4 is not accurate.

The only real way to tell nowadays is to check out benchmarks and reviews, there isn't a single magic number.

This is quite a good starting point:
