QUOTE(terradrive @ Sep 11 2015, 10:05 AM) Can just turn up the power limit for more performance than normal Fury. But prepare for louder noise. And yes, GCN cards are very efficient. The only thing is AMD had to set the hawaii and fiji chips to overclocking speeds on stock reference card to match the nvidia's card. That's why it is power hungry I still wonder why AMD don't want to pursue laptop market with fiji chips. It can be clocked lower and it uses very few components. They only started coming out Fiji chips for desktop.. don't think they'll pursue laptop market with Fiji so fast. There's probably still one more Fiji based SKU which is dual chip Fiji (R9 Fury Rage Roar Wow?).. |

Generally, every chip has a sweet spot (best performance per watt (power efficiency)).
For Fury X, I believe they already pushed the card to almost max (1050mhz) on stock, so the power efficiency is not ideal.. If they released FuryX at 900mhz stock, I believe the power consumption would match R9 Nano and NVIDIA's power efficiency, and the "OC" headroom would be 25% to 1120mhz. The R9 Nano actually gives a very good view on the power efficiency of the Fiji arch.
But normally reviews are tested based on stock clocks, so if they released Fury X at 900mhz, they would get disappointing reviews.. as it would be so far behind NV's 980Ti stock clocks..
Radeon's currently have so much untapped performance potential especially at DX11 games.. If they can somehow "fix" their DX11 driver, all their GCN based cards would be major performance boost.

QUOTE(kizwan @ Sep 12 2015, 02:53 PM) How do you guys define power efficiency? To me how much power is wasted as heat; power draw vs. actual power consumption; is what dictate whether power efficiency is poor or good. Just because power consumption is high doesn't necessarily mean power efficiency is not good. For me personally, it's defined as work done (performance) over power consumed. (work done/power input) |

QUOTE(kizwan @ Sep 12 2015, 09:00 PM) Then it should be called performance per watts ratio, not power efficiency. Thanks for your info. But industry standard of computer hardware mentions power efficiency too to indicate performance per watt. source |

QUOTE(hibiki98 @ Nov 29 2015, 06:34 PM) thanks bro. hahaa. normally i dont oc my stuff. treasure them. . so i should take r9 390>? dont want to regret later. how the dirext 12 software>? all game can run or just numbered games? Some games AMD do better, some games NVIDIA do better. All games of course can run.. question is at what FPS and settings... No idea what you mean by numbered games... DirectX 12 software... not yet release..can't tell yet.. both also support DX12. I don't think any dev will release game that can't run on a single vendor. Both card is good card. |

QUOTE(nzxkore @ Dec 30 2015, 10:02 AM) Hey guys.. Need some help here. My old gc giveup last saturday(gtx570) bought new sapphire r9 390 oc.. I update my bios to latest 4.3 p67a gd55.. Once i power on the fan not even spinning and no display on monitor. My pc powered by Vantec ion 2+ 600W. I did calculation and total load wattage is around 497w only. Thanks » Click to show Spoiler - click again to hide... « GTX 570 is 219W rated while R9 390 is 275W...maybe u should consider other card or new psu.. |

QUOTE(Acid_RuleZz @ Mar 15 2016, 01:54 PM) But Titan-Z is done, rekt by 295x2 till it can't see daylight. 295x2 price is below $1000 now and at one point you can even get it for just over $700. But i guess this card is more targeted for developer that want to optimize their game for VR. Make little sense if they targeted this for consumer market since next-gen is coming close. AFAIK, Dual GPU price performance was never good. IMO it would be weird if developer use this to develop for VR. The baseline is R9 290 and 970. Normally it makes more sense to develop for baseline card and this card's target market is too small for VR. And, I think this card's release is too close to new launch already unless AMD not planning to release their nextgen cards this year. |

USD 200 will be less than RM1k. Very good if performing like R9 390X. Lets hope the OC might be good hehe.

USD 199 for 4GB
USD 229 for 8GB
Performance per watt seems a bit better compared to NV Maxwell.
Weird that the performance slide doesn't include what preset used at the footer.
If compared to available benchmarks from Ashes website, it seems GTX1080 @ 58fps for ashes is 1440p (Crazy) setting. R9 390 CF is 61fps.

QUOTE(Master Ryu @ Jun 1 2016, 01:47 PM) But so far AMD is using R7 - low and mid range R9 - high end Maybe they think the card will sell better with more X's (like NVIDIA GTX). |
