Rumor has it the APUs shipped out of their store houses in November, and official release is planned for February or around then.

Rumors aren't the most reliable source, but given their roadmap they released a while ago I'd say that's a probable prediction.

Feburary might be a bit too long of a wait cause I hear Maxwell + a i7 calling my name if they dont hurry up plus it seems like kaveri is having issues, the fact they downclocked from richland cant be perceived as a positive sign.

What's the exact downclock comparison? Steamroller architecture is 20% more efficient than Piledriver, which is what Richland is based off of. The reason Piledrivers had such high clocks is because the modules couldn't keep up with two cores each. AMD has addressed this problem directly with Steamroller instead of just popping up a high clock, so that very well might be why it doesn't have/need as high of a clockrate.

They were probably trying to reduce thermal load for their stock heatsinks. I'm sure it will overclock just as well, if not better, than the other APUs assuming you have good cooling.

the thread here I read about it said 20-30% faster clock for clock, and the downclock is 10%. (probably to keep it at wattage). So a tiny bit faster, a gamewothy GPU. and really significant questions about heat output and overclocking. it may get quite hot when overclocked, which would only matter for laptops, or it may not overclock well at all. even if it won't overclock, it's still a pretty interesting chip. The first fm2+ I would seriously consider owning.

It's got steamroller cores on it, which have a smaller transistor size, with 1 module per core so I'm fairly certain it will overclock pretty well. I doubt heat density will be an issue for overclocking with high end cooling since the GPU cores are on the far side of the core, you'll just need an appropriate heatsink that doesn't focus all the cooling on the center of the die.

The HSA and hUMA capabilities are going to be an interesting addition for gaming.

Fair enough. The fact that they downclocked it however strikes me as a warning sign.

With upwards of 512 GCN cores I'm surprised they didn't downclock it more. They need to keep the thermal load low enough so their stock heatsinks can keep up with it.

Compare intel stock clocks to AMD stock clocks. Which ones in the same tier are better? Which one has a higher clock?

Intel will be slightly superior in the same tier, but have a much lower clock rate.

Architecture efficiency is much more important than the number of cores, or the clock rate in this case.

Steamrollers are AMD, so their going to be good for overclocking. AMD has made their place in the CPU marketplace as chips that are good for overclocking, and they'd be very foolish to pull away from that route.

I keep forgetting stock heat sinks exist.
