Overclocking Small Q's and Performance Q's

[Pixle]

I currently have a 2.41ghz Amd 64 3400. I'd like to know how you can come up with a formula or something to turn out what performance you would get with a Intel.

So that 2.41ghz * (formula) leads to what you would get 3.4ghz in this situation with intel. Just a rough sketch to know how fast you are going.

Another question is, do 64's ghz scale the same way intels do?.... I've seen different parts scaled differently and they all perform different.

Should a 2.43ghz amd 64 perform like a 3600 64? Is their a scaling for these?...thanks...I just want to know how far i'm pushing it.

AMD kinda make it up as they go along, but a few peeps like Zebo have a worked out "proper" AMD conversion math which gives the proper PR names to the chips.


well, a 3800+ runs at 2.4 Ghz aswell, only difference being is that it is S939 (dual channel) 3% more performance and I think it has less cache ( I take it from memory yours is a clawhammer? No wait I think the 3400 2.4 Ghz was a newcastle?)

the whole amd PR number thing is messed up.

Yeah it's really odd. How would you go about comparing your performance to other cpu's out their?....From the ghz point of view - even among amd cpu's?

a little faster overall than 3600 intel chip.

Proof?

Zebos formula is A64Mhz x 1.5 = P4
add 5% for dual channel
add 5% for 1 mb lvl2 cache

Example, what's a 3500? 2200 x 1.5 x 1.05 = 3465

whats a 3400NC? 2400 x 1.5 = 3600

K...I understand part of this. But why is the 3500 regestering 3.465 ghz (intel) and the 3400 is registering 3600 (intel).

3500 > 3400 at stock.

is their an exception from amd to amd?

Don't pay any attention to what AMD says..it's marketing which by it's nature is BS.. I gave you correct formula.

The 3400 beats the 3500 in every single benchmark.

so that means that my 64 3000+ s939 @ 2.5 (180$CAD) is similar to P4NW 3.9Ghz ~$400??

 

[Zebo]

on average yes, even a little faster 3950 depending on mem config... It will be faster in games, slower in some encodes...

 

[brazzmunk]

"some encode" processes similar to benchmarks such like sandra or pcmark? since i don't go too far on those
