Difference between Highend Intel and AMD CPU

Hello,

I just noticed that AMD has some very good while still cheap high end CPUs.

I picked AMD FX-8150 to compare with Intel Core i7-3820

What is the difference between these two CPUs? I am asking because the price difference is quite high. (In my local shop even higher)

If I was to choose either CPU I would be interested in high end Gaming and a little video editing.

you could game good with the 2. But the intel is a bit faster and in other apps much faster.
But if you go for intel you can better get from another socket, the mobo you need to buy for that 3820 is expensive and an i7 2600k-3770k are as fast as that one. But cheaper.(mobo)
 
The i7-3820 would far outperform the FX-8150, but an i5-3570k or i5-2500k would also outperform the FX-8150 in most scenarios, and it would cost a lot less.
 
I said that a bit wrong; I meant to say that the i5-3570k and the i5-2500k cost less than the i7-3820, not the FX-8150.

You could play every game with a good amd perfectly.

Oh thats good because I would like to try someday the AMD CPU I specified at the top (or its future equivalent) I think its the most expensive one that my local shop sells and its still far cheaper than many Core i7s.

The only thing that clashes in my mind now is the lack of support for PCI-e 3.0 on even the most expensive AM3+ mother boards. Is there any reason for that or is it just a matter of time?

Is there also anything else I should know about AM3+ motherboards that is different to Intel motherboards except that each is designed for different CPU.

Really? So the low price of AMD CPUs is proportional to its low performance?

No, that's just faulty math. :p I don't know US prices or prices anywhere else in the world, but here AMD FX-8120 is 30% cheaper than an i5 3570K, and it's not 30% worse. Sure, you might have to overclock it to see performance, but who actually uses a stock AMD anyway, eh? :D

many people who don't know what overclocking is :P
 
AMD make cpus, ATi make Gpus same company but massively different architecture.

CPU wise, AMD suck. Simple.
 
Bigfella has a point, currently performance wise, AMD is behind, otherwise this system would be running a AMD chip and not Intel.

They are behind, noody denies that. But they don't suck and they are well worth their low price.

But for gaming, at this point so few games use enough threads to take advantage of the "8" cores that overall an i3 actually outperforms an fx8000 series. Theres like 3 benches where it beats an i5 at stock, although an equal priced i5 compared to an fx with a cooler, the fx will catch up a lot and be better atsome things, but still prob loose overall

Im still holding out hope for piledriver, should have some leaks or official benches out over the next month or 2, hopefully ill get another build or 2 so i can do a new build for me, would love to be the first person here to try an fx8220 or 8320 or whateverit will be as long as the price is about the same

ATI doesn't exist any more...

CPU wise, for mid to top end, Intel is the better option, for budget builds AMD are still very good, so the blanket statement of "CPU wise, AMD suck" really isn't simple, nor is it true.

So the AMD chip is not that recommended right for gaming?

Why do they sell it and who uses it then?

Because not everyone games and because AMD are not going to develop a chip, realise it isn't as good as their competitors so just throw away their stock.

It is like a supermarket at the end of the day selling their produce for a low price because they can't sell it the next day. Even though, in theory, the produce isn't of as high quality as the other stuff on the shelf, selling it still gets money back on the money spent to produce it.

AMD have the chip priced at where the performance lies, but even so, Intel have the better option at the same price because they use less power and produce less heat.

It is 30% cheaper and in most tasks will perform equally or worse. Then if you buy it to overclock, you can overclock the Intel K chips, which aren't a whole lot more expensive from the lowest i5 to a 2500K or 3570K, but they will go further, run much, much cooler and use way less power.

You consider the fact too that a Thuban chip would be better than a Bulldozer chip, you have to ask yourself why would anyone take the FX over a Phenom II or an i5?

Consider too that in games, an i3 2100 will perform as well as an FX 8150, I am sure anywhere in the world that little dual core chip costs a hell of a lot less than that pseudo octo-core chip, here in the UK a little over a third of the price, yet the performance isn't there to match the price difference
 
I myself want IPC, vs number of cores, ive tried the many cores thing with phenom's, and it wasnt enough for me, as much as you can pump the clockrates up with a amd chip doesnt help with poor IPC performance.
