AMD Showcases Kaveri APU Performance at Computex 2013

Kaveri means friend in Finnish. Just thought I'd mention it. =)

Yes the power consumption goes up but the work done goes up as well, the work gets done quicker so cores can go back to sleep sooner.

But if the power drain and battery derating is larger than the performance gain, it is still a net loss on battery life so CPU/laptop engineers have to carefully balance peak power with performance to keep battery life within targets for the intended market.

If you have ever looked at power vs performance graphs, you can see that power usually increases much faster than performance. For example, on my i5 under full-load:
- 18W @ 1.54GHz
- 21W @ 2.24GHz - ~50% more performance for ~16% more power
- 30W @ 3.00GHz - ~35% more performance for ~50% more power

For mobile uses where people are starting to expect full-day use out of a single battery charge, pushing things beyond the point where power rises faster than performance does is generally not desirable. So, AMD pushing over 3.4GHz standard clock and boosts over 3.8GHz for laptops on top of AMD's massive TDP handicap on their performance APUs/CPUs would be pretty bad battery-wise.

But that could be solved with power profiles. Battery saver mode that limits the voltage and clockspeed to an efficient range, and then performance mode when the user doesn't care about power consumption.
Yeah when you increase clockspeed enough you have to increase voltage, and increasing voltage drastically increases consumption so it can't be a linear path of performance to power consumption as you said.

So a 2013 cpu built on the latest AMD core architecture that is very similar to the cpu in the Xbox One, is going to be close/equal to a console that is 8 years old?
pass me the pipe and load up whatever you're smoking because it has to be medical grade.

Either you're a great troll of you should go to rehab

Saying "latest AMD core architecture" is not necessarily saying a lot. I suppose you'll also imply that somehow a cheap APU is going to be faster than the dedicated cards from AMD, that cost more, in a given situation? It'll be a step up, but keep in mind AMD's core CPU architecture is very, very tired at this point. I'll save the trouble of explaining memory bandwidth, integrated GPU performance, and other things and instead suggest you go to Google and educate yourself on the topic.

Feel free to interpret the results. Most people do.

When will they allow dual graphics on higher end cards? 🙁
It would make sense to pair it with a mid range card such as an HD 7850.

The reason why people do not pair IGPs with higher-end graphics is because the huge performance discrepancy between the two often causes stuttering and limits performance to about twice the IGP's under ideal circumstances, which is a waste of time and lots of unnecessary frustration when the GPU alone already performs over twice as fast as the IGP.

gonna wait till dec-jan and look for benchmarks and will decide whether to buy kaveri or not. hope it will make trinity series like junk

No I would never imply that that a cheap APU would beat a dedicated card in terms of performance, I was simply saying that the APUs being released arent going to be on par/close to with the xbox 360 but the Xbox One, unlike what was said by the person I quoted who said that it would be on par with the 360

amd is rock,it will be big if they do it with 6 and 8 cores apu ,then intel surely down.after richland success Kaveri will kill intel,my friend take a-10 6800k and apu performing outstanding, bt i am waiting for new born......and it will be much better if it work 7850,7870 together,,,
