they're saying they got 10-15% boost just tinkering with the FSB or something... that they improved the efficiency of the cpu/gpu, allowing them to get higher base clocks with less energy, netting a 20-30% improvement in both cpu tasks and gpu tasks.

granted it was looking like the a10 will probably be seeing just a 20% improvement, while the lower end and laptop chips will see the biggest improvement. Overall, while the update is just a polishing of Trinity, it seems to be netting a solid improvement in performance. We'll have to wait till the chip is released to see if any of this is true.

And now everyone is forgetting that AMD was comparing Richland to Llano in their own words. I guess people just believe what they want to believe.

I was excited about the launch of the A10-6800K, but now after some research, only to discover that it richland is the same architecture as trinity! How disappointing. For AMD to claim that there are 15% increases in CPU performance and 30% in iGPU by increasing the clock speeds is just a bunch of baloney...

My A10-5800K overclocked to the same specs as they are offering on this launch gives the exact same performance increases. Artificial benchmarks consistently increase 16% on the CPU from 3.8GHz to 4.4GHz, and 30% on the iGPU from 800MHz to 844MHz (with 2133MHz RAM).

Now it looks like kaveri (with GCN) will not be launched on FM2 as promised. Thanks AMD...

http://wccftech.com/amds-kaveri-based-28nm-richland-apu-features-steamroller-cores-compatibility-fm2-socket/

Now we are being told it will launch on FM3, and may be backwards compatible with FM2. I understand the need for the higher memory clock speeds of DDR4/5, but when making the choice to go for AMD it was with the idea of HD 7750 performance from an upcoming APU on the FM2 socket.

Anyone else feel this way?

Overclocked Trinity = stock Richland... sure, but:

Overclocked Trinity < Overclocked Richland

and I'm pretty sure Kaveri is still going to be FM2 where did you hear otherwise?

I am basing by disappointing outlook on a few articles like this one:

http://lensfire.in/25341/news/amd-kaveri-apu-will-use-fm3-socket-but-supports-fm2/

And that I remember reading somewhere(?) that FM2 would get one CPU update before FM3. I expected that update to have the GCN cores.

Does anyone really see the industry moving toward DDR4 anytime soon? The wiki article here estimates 50% market penetration by 2015 (http://en.wikipedia.org/wiki/DDR4_SDRAM). That would make AMD a very early adopter IMO.

Do you think there will be the same headroom for OC'ing on the A10-6800K, or that maybe they have just realized that the APU can be stable at those frequencies and are shipping them out pre-OC'd?

There is not alot of headroom on trinity to begin with so my guess is that Richland is going to have a few internal tweaks to power management to facilitate higher clock speed.

I am disappointed that FM2 will be left in the dust, but at the same time it really is necessary...if APUs are to thrive they need enough memory bandwidth to compete with discrete cards. If you ask me the right way to do it would have been to have FM2 mobos available with GDDR5 sideport memory, or just keep FM1 around for another generation. But, hey this is cutting edge technology for PC's so its also good to see the changes that are needed.

DDR4 and APUs can't happen fast enough. DDR4 is supposed to double the throughput out of the gate. Current gen APUs are at the limits of bandwidth, so going to 512 gcn cores would need something (DDR4) to work effectively.
If Kaveri is fm3 but backwards compatible, yet supports dd4 in the fm3 setup, this will give those who have trinity 2 upgrade paths. First, Kaveri itself, then a mobo +ddr4 later.

AMD also has the tdp caps to think about, so a trinity at richland clocks will use more power (marginally) then richland at stock clocks.

Better yields = ?, better clocks of course.

Nope. That's what you get from better yields. Improved perf/watt

It's all just rumours right now, isn't it? And really the only time DDR4 will ever be first out is about 2014, where Intel will launch it with their Haswell-E of course and knowing AMD much later

OK so at first glance this looks like a pretty nice graphics performance bump, but then when I look at the numbers...wait a second, I've never scored that low with the 5800k...even before I started overclocking. Hmm, perhaps the 5800k is being fed slower RAM? Really the difference there is bigger than a 40mhz clock boost should be.

What would be fun is if they can some how open up dual graphics compatibility to include more discreet options.
