Default Help, AMD X2 4200+ or 4400+ for £90 more?!

Hi guys,

I am nearly drawn to a final decision on desktop, but my budget of £1000 is getting a bit stretched.

I was wondering, how much better is the 4400+ X2 than the 4200+ X2? Is it worth £90 more? I know it has 2mb of Cache as apposed to 1.

I need to know, as otherwise I've got it sorted so the final spec would be:

- AMD X2 4400+ or 4200+
- 2048mb of Corsair RAM
- ATi X800 GTO
- DVDRW+/-

etc etc 200gb hdd, and anyway, I just need a final verdict because the monitor I want is what is stretching over the budget and with the £90 less price, I'd be able to afford it...!

If you need the money, get a 3800+ x2. It can overclock to the speed of an 4200+. Get the 3800+ or the 4400+.

Just get the X2 3800+ and overclock it. If you dont plan to overclock get the 4400+

But, what is the speed difference between the 4200+ and the 4400+? Is it really large? what clock speeds does this equate to, (I've never fully understood the AMD system of ranking their CPU's....!?

it's really quite simple. look at the P-rating
the only difference between the 4200+ and 4400+ is the extra cache. sometimes this gives good benefits, sometimes you won't even notice it.

What P-Rating?

Like if I were to say, AMD X2 4800+ just like that, how would you know what clock speed that has?

the 4200+ and 4400+ are both clocked at 2.2ghz. the difference is in the size of the L2 cache which does make a noticeable difference in games. i would suggest either getting the 3800+ or the 4400+, i think the higher clocked versions of each core are a waste of money. also you may be interested in the opteron 165 if you might plan on overclocking. it is clocked at 1.8ghz and would perform roughly similar to a x2 3800+. however this is a very good overclocking processor and i hear in america (unfortunately not in australia and i don't know about the UK) it is cheaper than the x2 3800+

edit: you can't tell clock speed by P-rating. clock speed is really an irrelevant way of measuring cpu performance anyway. i can see you are someone who more easily understands the pentium clock speeds. that is the purpose of a p-rating, it gives the approximate p4 equivelant of that cpu in mhz. so the 4400+ is roughly equal (or better than) a pentium 4, 4.4ghz. however if you use the cpu for video encoding or something else that takes advantage of dual cores/multiple processors it will be roughly equivelant to 2x3.7ghz pentium 4's. the p-rating of the dual cores is from a benchmark of standard programs, most of which do not take advantage of the dual core architecture hence such a low score despite the fact that each core is very powerful

Awesome cheers for the details, but I'm gonna stick with the 4200+ as I really am not the kind of person for overclocking, or noticing tiny differences!

Thanks for the help guys!

You didn't say what you intend to use your computer for. In most instances, the X2 4200+ should be just fine. If you are a big gamer, then yep the 4400+ will give you a little more juice.

I thought Dual cores are not suitable for OC
