CPU Pros and Cons

  Abel 10:32 27 Jun 2008

I'd be grateful if anyone could enlighten me on the pros and cons of :

AMD Phenom X4 9550 2.2 Ghz with 4x512K L2 cache Socket AM2+
AMD Athlon 64x2 4200+ 2.2GHz with 2x512K L2 cache Socket AM2

Apart from the Phenom CPU being quad core as opposed to dual core of the Athlon, is there any great advantage of one over the other? I really have no understanding of the dual/quad core effect

dual core and quad core is like the expansion from what hyper threading tried to do.
Dual core is literally 2 cores inside the CPU so it is essentially 2 CPU's in one, which means you can do 2 heavy CPU tasks at once. and it is very quick.

Quad core is the newest version of the multi-core revolution, quad core is a little expensive but is 4 cores in one, so, it is again double the speed of the dual core, as it acts as 4 CPU's being able to dealw ith 4 heavy CPU tasks at once with ease, or quickly get through 1 task as a team.

that is the difference between a normal standard core, a dual core, and a quad core.

I have the Phenom Black Box Quad core in this machine, and it beats all my dual core CPU's hands down.

Particularly in games.

If you don't play intensive games, then go for an FX dual core CPU. If you do, the Phenom is the one.

i'm looking it up now but judging by the title, 1 is 64bit and the other might be 32bit. If this is true then you are stuck with only one of them to have as they have to match the bit of your motherboard.

Sorry, i am mistaken, the Penom is a 64bit processor, so, to have one of these processors you have chosen you need a 64bit motherboard.

So, there really isnt a difference but the speed.

The quad core needs 95 watts to run, whilst the dual core needs 85.

And as for the port it wants, the quad core wants Am2+, but is back compatible to AM2 and vice versa. So ur dual core will work with AM2+ aswell.

The difference between them is that the AM2+ can go up to 2.6Ghz, and AM2+ has a 2 power planes that support two fo the sections of the pocessor which saves power over all in your machine, the power is, although, an AM2 processor can use a AM2+ port, the processor must be AM2+ to be able to take advantage of these AM2+ benefits. SO, what ever port u have i would definatly recommend the quad core.

if you have a lot of background programs running, you may notice a performance increase on games etc with a quad, however i only know of 1 games written for a quad and that has just taken a backstep for the time being. its like when dual core came out it took a while for programs to be written for them. common programs are written for the most popular (average) system so most people can use them to full effect.
i have an amd 6400x2 @ 3.6hz system and a QX6850 64 bit system they both play everything at full settings with little difference as programs can only be taken so far.
the quad will be more future proof at the moment i think there's little difference depending how much background crap you have running.

Quad cores, as a rule ATM, are only beneficial for video and 3D rendering. As adman says, there are not a lot of programmes written yet for quad cores for the mainstream market. You would be better with the fastest dual core you can afford.
BTW, Intel beats AMD hands down at the moment for bang per buck. (And I'm an AMD user!)

  OCRIDION 12:07 27 Jun 2008

Yeah, take into consideration the differences i explained, but try to think which is right for your use. Do u really need to speed that the quad core can offer. Though, I still say it good to be able to save power by using the ATM2+ technology. But its not worth the extra money of the extra beneift of extra speed is worthless to you.

Thank you all for your feedback.

I'm in the process of determining the spec for a new computer I'm thinking of ordering from PC Specialists. As I'm not a gamer, but more a user of spreadsheets, word processing and other business orientated applications, as well as the Internet, it seems that dual core will more than adequately satisfy my needs. My particular concern is that should dual core technology suddenly become redundant to quad core, my expenditure in new kit will have been in vain.


  Abel 12:45 27 Jun 2008

Since posting my thanks I've looked again OCRIDION's explanation of standard, dual and quad core technology. Am I to understand, therefore, that a 2.2GHz quad core CPU will operate at the same speed as an 4.4GHz dual core one?


  Ditch999 13:52 27 Jun 2008

Sorry, it doesnt work like that.
Each core works at a maximum of 2.2ghz. That is where programmes written for multi core CPUs come in. They can utilise the other cores at the same time and get the job done quicker. Ordinary software will still only use a single core of a multi core CPU but if you run 2 applications at the same time, like windows media player and IE then each application should use a seperate core.
