AMD Phenom II X2 565 and X4 955 vs. Intel E7600 / I3 540?

post #1 of 9
Thread Starter 
Hi,

I am pondering on moving from Intel to AMD but before I do that first I need to check if I have the correct picture. It seems to me the AMD is a lot faster and cheaper than Intel - but if I were right then everybody would have AMD and that is not the case.

So: I have an Intel E7600 - 3.06 GHz Core 2 Duo, 2 cores. If I wanted to buy this new now I would have to pay around £100. You may say this is an old model and you are right. So I also checked Intel I3 540 which is 3.06 GHz again. This costs around £105.

The competitors: AMD Phenom II X2 565 Black Edition 2. 2 cores, 3.4GHz, 7MB cache... Seems faster that Intel E7600 or I3 540 (although I couldn't find any speed comparison test for these two) and it costs only £65. Big difference. Also, look Phenom II X4 955 - 3.2GHz, 4 cores and it costs £105, just like Intel I3 540. But this AMD has 4 cores while I3 540 have 2 only (but again, I could not fine a Phenom II X4 955 and I3 540 performance comparison test).

So... Why AMD's are so cheap? Why Intel is so expensive? Also, I would need this computer for gaming. I noticed that most of the gamers have Intel? Why, Intel? AMD seems to be cheaper and more powerful? I feel there is some bits that I miss? Please help me to see this more clear.

(My situation is that I have an old Intel E2140 and and Intel E7600 processor, a motherboard that supports these (but not Intel I-series) and that supports DDR2 (but not DDR3) and also 2GB DDR2-6400 (extra fast 4-4-4-15) and 4GB DDR2-8500 memory. I am pondering (far from deciding yet) over selling the two processors, the mobo and the 2+4GB memory modules (both are 2*1 modules kits) and buy something new from their price. Question is: I3 or Phenom II? (I won't say I5 as it an I5 650 starts at £145 and it still has only two cores!)

Thank you.

AMD is faster in the same price class.
But Intel is fastest overall.
i7 currently has no competitior in the AMD camp.

I'm a Intel user as well. Correct me if I'm wrong. I know there is a Phenom X2 processor can be unlocked to a X4 which I believe is amazing and bang for the buck. You only need a really good motherboard. Not all motherboards are good at unlocking extra cores.

If you are going for gaming just make sure to pick the processor with higher Mhz so that you won't have a hard time going a bit further when overclocking. For example if you buy a 2400Mhz/2.4Ghz you can overclock it to 3Ghz easily and if you go further close to 4Ghz you'll need some serious cooling. A processor with a stock clock of 2.8Ghz would be good if over 3Ghz even better.

Hope it helped you get some idea.

all phenom x2/3 can unlock to x4, but not all will be stable

dont buy an x2/3 planning to unlock cores, its a bonus if they do unlock

not all motherboards can overclock well, msi boards have been known to start on fire with mild overclocks

If you have £100 for a CPU alone, get AMD 955. Its £99 at cresent electronics.
http://www.crescentelectronics.co.uk...processor.html

Its a C3 as well that allows upto 1.425v, so you should be able to get 3.8-4Ghz with a decent cooler.

To expand on this - if you want to run a quad core AND overclock it, either use a very mild overclock, or have more than 4+1 phases to deliver power to your CPU.
(i.e. buy a good motherboard, read the descriptions and tripple-check if it's a newer MSI motherboard).

The Phenom II x2 isn't as good at multi-tasking as the i3 is, nor is it quite as fast clock for clock, and I don't think it overclocks quite as easily. However, it's near half the price and MIGHT unlock to an x3/x4.

They're brilliant value for money, but as I just explained, not as good in actual performance. That means to beat the i3 in performance, you need a Phenom II x4 clocked a bit higher (usually. Well multi-threadded apps are an exception).

Yes its like Korlus says. If your going Phenom get a board with quality mosfets and a heatsink. you'll need it since the TDP will be pretty high if it unlocks succesfully
