that is why AMD paid 8 million to DICE to use Mantle upon developer request.If it was developer request than why Amd is paying because it just rubbish and marketing nothing more.Even John Carmack the creator of Linux and Doom game has mantle and Nvidia OpenGL has no difference but both cannot be used.

In Logic what i am about to say will be hated by AMD fanboy but it is a Fact.
Let start No Dev will make Mantle as a first priority because they need to target all gamers.AMD saying they made Mantle on Devs request so where are that Dev and why they are paying so much money to apply that api.If Dev want a low level API so u think they will ask AMD to develop which dont even have a market of GPU and processor.

If dev avoid opengl or dx and starting using AMD API than Dev have to bare a huge loss which i think it will be an idiot if they do it because AMD dont have the majority of GPUs user.It is fact Nvidia has the market stock and they 65% of GPU user.

It cannot be used until AMD pays them in huge amount or else dev will go bankrupt by applying only Mantle.

But Console will not use Mantle so the take that word port out.

titan score is around 6xxx to 7xxx

It is not even near to titan in 3dmark.

NVIDIA is developing something BIG and it's not a GPU

i giving ur answer.

So actually in normal res to 1440p or 1600p it cannot beat GTX 780 but the price is dam good but as GURU 3D and Aanadtech say it go to 95C and a lot of noise problem.

I was planning to but what hold me back is that i have 4 way sli mobo and R290X u cannot gap between them so what i meant is that if u CF than u have to use PCIE 1st and and 2nd slot and u cannot use 3rd slot it will not detect what so ever.

New CF.It will not CF if use gaps.It allow u to Gap.Even Guru3d also was shocked wait see here what i meant.

Although i can cook my food or breakfast on R929xx and there is no need of matches kitchen revelation tnks to amd save time and save money.

I am a student and live alone and i cook for my self so i no need to buy matches any more.

Default [THW] Review Samples vs Retail R9290x boards(large differences)
We first observed differences between the Radeon R9 290X cards that AMD sent out for review and the ones being sold online just before our R9 290 coverage went live. After additional testing, we have answers, feedback from AMD, and more questions.

Leading up to the Radeon R9 290X launch, I had two cards in the lab, both supplied by AMD. They ran at slightly different core frequencies in single-card configurations. No big deal, right? That was just PowerTune doing its job. But paired up in CrossFire, even with plenty of space between them, heat build-up forced the pair to drop to even lower clock rates. Right away, I was able to establish that AMD’s Hawaii GPU operates within a range of clock rates, determined by a number of variables. For R9 290X, that range starts at 727 and ends at 1000 MHz. As an aside, I do have an issue with vendors simply advertising this as a 1000 MHz GPU.

The discussion that so badly requires clarification, however, is a derivative of Hawaii’s inherent behavior. Because the GPU is always trying to run as fast as possible, and then adjusting down to obey certain power, temperature, and fan speed settings, every card is going to be just a little bit different. This is expected, and applies also to Nvidia’s GPU Boost-capable cards. But when I got my hands on a retail card purchased from Newegg, it was way slower. Like, 20% slower in many cases.


So that left me wondering: were the press boards just lower-leakage parts able to sustain higher clocks? Without a definitive answer, and with AMD insistent that my results couldn’t be right, I approached the Radeon R9 290 review much more cautiously, presenting data from both the sampled and store-bought 290X cards.

A Break In The Story

Then, on Tuesday, I received word from AMD that it had a smoking gun.

All of my numbers were generated using Quiet mode—AMD’s name for its 40% PWM ceiling, designed to keep acoustics in check. That’s a signal representing a percentage of maximum voltage into the cooling fan. So, from one card to another, 40% should yield roughly the same fan speed. Variance in fan speed is limited to the mechanical components, and should be very small.

But as it turns out, 40% on the cards AMD sent and 40% on the retail cards do not equal the same fan speed. To confirm, I compared the press card to a retail boards from Sapphire and Asus, using our Battlefield 4 benchmark at 2560x1440 and Ultra detail settings.

hail to AMD.

Yes and R2 290,R 290x and R2 280 all went up to $80 to $100

Really hard to believe that actually this card is really good for gaming but most of people is not buying it for gaming but to do business.

Dont worry AMD buyer and user already complained and AMD Roy is seeing this issue and he will stop and limited purchase for business use.

I now it is of the topic so plz it is just one question what the hell is this bitcoin.

same price as gtx 780 reference price.

Now Nvidia is more cheaper wow.I really did not expect that.

Do share benchmark.

i am thinking of getting R9 290(4) can any tell will damage my mobo or something beacause of heating issue

Plz guide me that how is really Xfire performance of R9 290 and i dont trust reviews.I trust real time experience.

i talking about R9 290 Cf performance what really hold me back is this
http://www.overclock.net/t/1440600/r9-290-...-with-crossfire

The Crossfire dont work well in past games and some new games as the thread says.
