That 3X performance per watt claim was about the memory subsystem not the entire card. HBM delivers 3x the performance per watt of GDDR5, that's what it means essentially.

You should read the fine print, no really. http://i.imgur.com/xuWUyS7.png

Well looks like they nailed every single duck with the fury specs.... gotta give it to em, they've got a mighty shotgun. http://wccftech.com/amd-radeon-fury-x-specs-fiji/

It's not speculation AMD said Nano has 2X perf/watt as the 290X, fury X only has 1.5X. Just like CPUs, when you clock the chips down and reduce the voltages the efficiency improves. The R9 285 for example is a 190W card, the mobile version with even more cores 2048 vs 1792 and only an 850mhz clock speed vs 918mhz is rated 125W. http://www.notebookcheck.net/AMD-Radeon-R9-M295X.129043.0.html

Lower clock speeds, lower voltages, specially selected low leakage chips. We already see this with mobile vs desktop graphics cards. Often having the exact same configuration but lower clock speeds and much better efficiency.

Would you kindly provide a screenshot of your BIOS ? you can do this by plugging in a USB storage device For 4.5Ghz you should need no more than 1.425-1.45v

Listen carefully because this is going to be the most valuable information you're going to get. I'm not trying to be cocky but I genuinely believe this. You did not lose the silicon lottery and your board is plenty enough to take this chip to 4.7Ghz+. Here's the deal, because I overclocked multiple FX chips before. When you ONLY change the CPU voltage it's NOT the ONLY voltage that changes. CPU NB, HT link and other voltages also change with it as long as you keep them set to AUTO. This is what's causing your stability issues. Reset the BIOS, go LOOK at the actual default voltages in the BIOS when they're set to auto. If it reads 1.2v you set it to 1.2v, if it reads 1.1v you set it to 1.1v. I'm referring to the CPU NB and HT link and SB (south bridge) voltages, check other voltages as well to see if they change when you overvolt the CPU. I can't remember all of them exactly. But I distinctly remember the southbridge being one of them and a major culprit in instability. After you've MANUALLY set the voltages to their default settings, you can overvolt the CPU and overclock it. You can proceed to very SLIGHTLY increasing the voltages of the CPU NB, HT Link and so on to improve stability if need be. But your increases will not be nearly as high as what setting these to "auto" would do when you overvolt your CPU.

The Fiji XT based FirePros and the R9 390X will wipe the floor with this. Full HSA support, over 8 Teraflops of single precision compute and over 4 Teraflops of double precision compute, 16GB of HBM and undoubtedly half the price with 250 TDP. And let's not forget all of this is going to be on TSMC's 28nm process and a 550mm² chip. The Phi is over 700mm² large on 14nm and still only manages 300W TDP. With the same process node Fiji XT would literally be half the size and half the TDP with a 25% performance advantage.

Mac doesn't support flash mate.

Swedish Kronor. 7999 is equal to 799 Euros. Just a placeholder, remember when the 290X was listed on etailers for $799 prior to launch ? same thing.

I'm still waiting on the new cards to upgrade to a 4K Freesync monitor.

AMD registering 400 million GAAP losses, but actually made $50 million profit. This is including their $300+ million fine to Glofo for cancelling wafer orders.

To be fair a $1000 CPU even if an eight core isn't revolutionary by any measure.

I'm pretty sure they're talking about the future. As in with the new Zen core by the legendary Jim Keller.

Meh, no bridge is the way to go.
