With regard to the 45W A8-7600, it is Kaveri APU with the bigest increase in CPU Multithread performance no doubt or 600mhz higher defoult CPU frequency+up to 20% beter IPC.

"The ($119) A8-7600 is the real standout of AMD’s new lineup. It epitomizes everything we could want from Kaveri by incorporating the graphics and multimedia performance of a 95W A10-6800K into a part with a TDP of just 65W. More importantly, it can be easily configured down to 45W without taking a massive cut in the areas that count the most to its intended market: GPU accelerated decoding, transcoding and gaming. I’m not saying forget about the K-series parts.
The A8 7600 makes one hell of a convincing case for itself in HTPC systems and simple set-top boxes. Intel doesn’t have a thing that can touch it within their current Haswell product stack.
By combining graphics horsepower that’s focused in key areas and “good enough” (for its segment at least) CPU performance into an efficient, affordable package, AMD has created the perfect poster child for their design mantra and a great companion for SFF systems. It may not have the overclocking chops of its more expensive siblings but the A8 7600 is infinitely more capable of displaying the best Kaveri has to offer."

just WTH are you on about? there are linux drivers available, and the FOSS driver is there,
A 45W Kaveri pulling slightly more than a 54W Haswell can be explained quite easily with platform power. I'm not familiar with A88X, but platforms like 990FX were stupidly power hungry, much more so than their Intel counterparts. There is also the issue of VRMs in use.
Was the 12% overshoot temporary? AMD's whitepapers state that turbo will push chips above rated TDP for a "thermally insignificant amount of time". Was this for a second or two? Or was it sitting at 140W constantly? If its the former AMD have not been deceptive.
That is the best analysis of the AMD Kaveri!
Stick a fork in AMD;They're done.5 years it's been and they have been going down this stupid Bulldozer road for too many of them.No server market share,they lost that.FAIL;head-up-the-assery FAIL.
5 years,and less performance;That's not going forward.
Oh;and higher prices:955 BE released @ $165
Yeah,I wanna pay more for something with 80% of the performance of something you made 5 years ago.
This explains why there is no FX series lineup for the next year or more. An FX series chip using steamroller architecture would either see no performance gain or wind up going backwards without onboard graphics and the advantages of hsa and huma.
Wow, AMD over promised and under delivered...Again.
They get credit for being consistent at least.
Kaveri is 5.8% faster at games & 7.5% faster at applications than Piledriver @ fixed 3.7GHz.
Which versions are being compared? Don't forget, the FX Piledriver chips have L3 cache, which Kaveri does not. For IPC analysis of the architectures, the appropriate comparison is Richland and Kaveri at the same clock speeds.
While the Hardware-canucks wording is not as pathetic as the conclusion on Anandtech -which devolved into some edge-case grandpa story in desperate attempt to justify Kaveri- it is not much more informed, either. It is a facile analysis that can be turned around thus: Intel have created a great CPU (Haswell) with "good enough" iGPU (for its segment, at least) blah blah.
Everyone seems to be overlooking that AMD's APU have been thrashing Intel's HD Graphics before Kaveri, yet how much of a sales success have they been? Why should things suddenly change now? The big thing AMD is pushing this time is gaming, but AMD's lead in iGPU over Intel HD Graphics is not big enough to obviate a GPU card for gaming builds. Their benchmark is not (and should not be) Intel, but their own entry-level cards.
AMD can have 200% performance lead over Intel in iGPU, it will not amount to anything until we can play most titles comfortably at 30 fps or higher. But then AMD run into possible cannibalization of their own GPU card business....next few years are going be fun for both AMD and nvidia.
And Kaveri's iGPU lead is certain to be smaller in TDP restriced notebook chips. With their pathetic HD Graphics Intel already manage to lead AMD in some graphic benchmarks in ultrabook segment. With Broadwell they will take another big step forward and things should be closer than ever. I would not rule out Intel's Broadwell matching AMD's Kaveri upto 25-35 watts, above that -and for desktops- AMD will continue to lead the iGPU for a while.
Contesting for GPU superiority in the TDP restricted enviornment is not as easy as producing 200 watt+ GPU cards, as both AMD and nvidia are learning.
The 45 W TDP Kaveri chip seems to be the one that performs best (within its TDP category).
Does this mean we can expect coming mobile 25/15 W TDP Kaveri based chips to perform well too? :hmm:
Yeah. The problem with Kaveri is that it is a desktop LGA chip, and only applicable to extreme low end systems such as HTPC. Personally as an HTPC chip it's okay but there isn't a single sane person that is going to use this as a power rig for desktop gaming. Nobody would buy this over a 4770k for a high end rig.
AMD has essentially cornered the Kaveri into the low end desktop space which is mostly used by HTPC, while most desktop users will get a 4770k with a dGPU. And a 4770k will obviously trounce it in CPU performance. Being that Kaveri is cornered into the low end, the profit margins for that segment will match. Slim margins.
Kaveri is slower than Richland (overall) in Hardware.fr tests! Very disappointing CPU performance IMHO. Similarly priced i5-4440 is a much better CPU to pair with discrete graphics.

The Richland T models are 45W too. So what does this graph tell you?
