AMD FM2 - compared to AM2/3 are ... ?

AM3 platform allows higher wattage CPUs with more cores compared to FM2 and generally more fully-featured boards with better overclocking potential. Socket FM2 has a max of 4 cores whereas AM3 has 8.

FM2 generally has CPU's with integrated graphics (APU's) although there are exceptions, there are no APU's in AM3.
 
I don't know the answer to your question, sorry :-(

I did think that the Kaveri/Godavari chips had better single threaded performance than the AM3's though?

I really am gonna have to look into this myself to see the answer.
 
Originally the FM socket was for APUs while the AM socket was their high performance socket. I remember the early FM APUs using a cut down version of the AM CPUs. But then Bulldozer came out, and was a complete mess, causing AMD to shift their focus away from the AM platform and onto the APUs which made them more profit. This then meant development for AM pretty much slowed to nothing, and Piledriver's successors was then refocused onto the FM platform instead.

I do suppose that does mean in theory the newer FM APUs "should" have better IPC performance, but the AM CPUs should still take the lead with overall performance thanks to the higher power rating, higher speed, more cores, etc.

Once Zen comes out though both sockets will be unified with AM4, which is a successor to both sockets.
 
What I can tell you is my lad has a A10 6800k and it works flawlessly with his R9 270

I know it's a bit of a waste of the APU part but it started off to replace his old laptop and adding the GPU was a the easiest/cheapest option to make playing BF4 OK and he's still happy with the performance.


....and it's never been overclocked yet as there isn't the need.
 
Thanks guys.

I know that it has the APU included over the AM CPUs, but thats all I knew really.

I went through the AM3 to AM3 path, and found the AM2+ boards and so on... I have a young lad down the road from me, who has come to me with his setup as he could not get it working, and what he has done, is bought himself an FM2+ CPU, however the Mobo is an FM2 ( NOT PLUS ) and they dont physically fit, by one pin by the looks of it, however, somehow he managed to bend a wehole load of pins and I have straightened them up but the CPU still wont work... The Plus issue obviously.

The thing is, that he has bought this to replace his current AM2 setup and I am not entirely sure that he has actually doen himself any favours because he has not actually upgraded really, more sort of side-graded... He can now get DDR3 compared to his old Mobo and thats DDR2, oh and his old CPU is a triple core, while his FM2 is Quad, and I dont know the Speed.

I think he would have been better off buying an AM3 SETUP instead!!!

Hell, I got an AM3 setup upstairs doing nothing I could have let him have!

Anyway, much thanks guys.
 
I honestly wish I could have answered your first questions and given you a clear answer on comparative performance, sorry that I was unable. However, as the topic seems to have moved on...

Which model FM2+ APU/CPU is it? If it's a reasonably decent model, and he has a gfx card, he is not going to be disappointed with the performance.

The question now would be, depending on the model of APU/CPU, is it better to get him to replace the chip or the motherboard?
 
He has taken much of what I have told him on board.

I dug out an old Phenom 955 thats spare, and it works in his old board a treat.

He bought himself a low end AM2 CPU ( Not a plus ) and Im unsure what he has bought, but I iwll find out later on I recon.

He has finished building this PC up, and I do admit, that its all white and blue, and honestly looks gorgeous, and his father has done a reallyu nice thing and said that he will buy that PC off him for the price that his son paid for it, so he will get a new PC out of it, and his son will get his money back to have another go.

I have also said, that when we does upgrade all his stuff, then I wil lswap all of the rest of that old setup ( thats using my AM3 ) back, but, I will give him 16GB of DDR to kickstart him off.

So, I think that overall, he is very happy.

I have told him to tyalk to me before he buys anything just to make sure that is going to be the right parts, but I also said to talk before he tarts to pay for anything to kniw what he is gettign himself into! - I mean... He could end up buying a Sempron / Celeron setup thinking that it would be good enough, but as anyone knows, they are nowhere near any kind of Good.
 
That's very nice of you :) I hope he manages to get it all sorted out and learns something new in the process.

Please let us know what happens with his setup, and where he moves onto with his potential new rig (after he sells to his father).
 
I enjoy doing it.
Im very lucky in that I own a ridiculous number of PCs. I am a real hoarder I will be honest, plus, I will look for any excuse to buy more PC bits.

I have given him a CPU that I will eventually get back, its a CPU that is not being used anymore ( although lets be honest, its still a seriously powerful CPU that will do anything that would possibly need to - Especially, given that he is using a GT 610 ).

So, I am not losing out am I? As I told him... When he does sort out his next PC, I will show him how to do it properly and carefully, and hell, most of us have done something similar at some time... I remember my first ever CPU mess up was on a 486... I upped from a DX66 to a DX100 and the CPU was a 3.5v job but the previous one was a 5v one... Back then, you didnt just plop the CPU in, you had to set jumpers to sort out the FSB, MULTI, VOLTS and all kinds of junk before you plopped it in... Not lie these days...
Anyway, it went pop and that utterly ruined me cos It cost me a months wages back then... Well ok, not quite, but it was a lot of money anyway.

My most recent **** up, was semi-justified because I was only giving a lad adfvise over the phone at first, and he was upgrading his PC and he had an I7 and he wanted to up his Mobo for a better one. He asked if a particulr one was good... Dunno now, but Im, sure it was a guerilla or something?? And yes, I said it was lovely, but th\t turned out to be a different CPU type, and at the time, I did not know thatt here was anything other than the one type???

Still, he was a nipple and ended up buying a new CPU to go with it and I had his old I7 as payment for helping him, so win-win... That was my first I7 too! - Still got it I think? - Yeah, 1156 2.93Ghz Im sure thats in my youngest sons PC??? He never uses it.

Hey Im waffling. Enough.
