4,3GHZ locked chip would likely outperform Intel's Iris solution.

(95W part clock's 3ghz when full GPU load)

4.) It is possible to break this barrier with manually changed BIOS settings, but this is more than this cooler will survive.

I measured in worst case above 150 Watts for this APU - too much for the Wraith cooler and at the end totally senseless.
The same cooler can cool FX-8370 even at 4.9GHz.
Does it work according to his expectation, I wonder. There have been plenty of indications that the limits are set through software, how he associates the restriction to the Wraith Cooler is beyond me. 50 watts of extra overclock headroom at the very least.

I have to admit, AMD is really on to the APU scene. If only they could break out of the shell of DDR3, these would be truly respectable processors. Also, if they could get a break in the laptop and notebook market, these APU's would bring them back from the undead. Here is to hoping that Zen will finally make them semi competitive at least.

Also, don't quite understand how the reviewer states that the Wraith cooler can't handle the APU... I am running a 7850k now on a stock old style cooler, OC'd to 4.3GHz. The Wraith can handle a 8 core FX at 4.9GHz, those get muay caliente...

Another pointless APU. I still dont know what people see in them. iGPU performance is poor and cpu isn't the best either.
And they still haven't fixed the cpu throttling.

What a waste.

I wish intel would release HD550/HD580 in desktop cpus like i3/i5. Would totally kick amd in the iGPU butt

because some people don't want to spend an extra $300 for a gpu just to play games. If intel can somehow get a 980m and cpu to work as one they can win but as far as I know it AMD has the better APU

You really don't need to spent 300$ to game. You can grab 250x for cheap.
And looking at the whole platform cost, a 250x and a cheap pentium/athlon will cost less than expensive 7870/7890K and faster ram (because you need it to take advantage of the iGPU).

From a price/performance perspective, apus (especially higher end like this one) make no sense.

its for ease of use. Some ppl (like me) get these to build computers for second hand use and don't want to have the hassle of looking up spec for a gpu and hooking up the gpu when all you need is just the cpu to do both.

I didn't have any throttling on my 7850k, though I don't know if that chip had issues. Also, the iGPU really isn't that bad, and these chips can do well as an htpc.

This too. Good point.

Its a very poor argument really.

Every APU throttles to 3Ghz when iGPU is used.

for you, yes. but to others it's a justifiable choice.

tell me a situation when buying apu is justifiable but pentium+250(x) isnt ?

If you want to play games but are either young or poor or both and budget for gpu+cpu is say ÂŁ60.

ease of use
driver installation/download
specification of the gpu ie size and wattage
Pentium is for normal computer use ie viewing internet etc. Try gaming on it you will have problems once the better games start eating your cores away.

looks like the other people have spoken on the matter, with justifiable purposes as to why one would get one.

In that case, you're better off with a used setup. You get A8 7600 for that kind of money. Thats the slowest 4 core apu (i'm not gonna count 2 core apus, because they are trash).
Its a locked part, still needs dual channel ram to get any decent performance out of it at all and has a dead end socket.

Nowdays, if you're on fixed budget, its actually better to go with something like a g4500. Costs less than apu, but has beefier cores and a pretty decent iGPU aswell. Good for light gaming before you get another allowance for a better dedicated gpu.

And how is apu gonna be bettter ?

How is apu easier to use ? explain that ?
You still need to install drive for the gpu. Just like if you had the 250x. No difference here.
Power use will be marginal at best so you can get away with a cheap psu on both ends.

Light gaming will be just fine (with a couple of exceptions, because f--k optimization). And you have the huge benefit of upgrade path, while with apu you have to replace everything. And that can happen today if you decide to stick a midrange gpu in the mix (think 960 or better).

Again, apus make very little sense if you put some though into it. Not just ... "Oh a new toy that has everything".... "jack of all trades, master of none":

I think a genuine advantage of APUs, where they actually make sense is HSA. There is a huge benefit compared to pretty much anything else.
