More Radeon R9 390X Specs Leak: Close to 70% Faster than R9 290X
Earlier today, AMD reportedly showed its industry partners (likely add-in board partners) a presentation, which was leaked to the web as photographs, and look reasonably legitimate, at first glance. If these numbers of AMD's upcoming flagship product, the Radeon R9 390X WCE (water-cooled edition) hold up, then it could spell trouble for NVIDIA and its GeForce GTX TITAN X. To begin with, the slides confirm that the R9 390X will feature 4,096 stream processors, based on a more refined version of Graphics CoreNext architecture. The core ticks at speeds of up to 1050 MHz. The R9 390X could sell in two variants, an air-cooled one with tamed speeds, and a WCE (water-cooled edition) variant, which comes with an AIO liquid-cooling solution, which lets it throw everything else out of the window in psychotic and murderous pursuit of performance.
It's the memory, where AMD appears to be an early adopter (as its HD 4870 was the first to run the faster GDDR5). The R9 390X features a 4096-bit wide HBM memory bus, holding up to 8 GB of memory. The memory is clocked at 1.25 GHz. The actual memory bandwidth will yet end up much higher than the 5.00 GHz 512-bit GDDR5 on the R9 290X. Power connectors will be the same combination as the previous generation (6-pin + 8-pin). What does this all boil down to? A claimed single-precision floating point performance figure of 8.6 TFLOP/s. Wonder how NVIDIA's GM200 compares to that. AMD claims that the R9 390X will be 50-60% faster than the R9 290X, and we're talking about benchmarks such as Battlefield 4 and FarCry 4. The expectations on NVIDIA's upcoming product are only bound to get higher.

Also, with the factory cooling it seems like there will be a variant with the liquid cooling, not all of them.
Price is high, but I only hope they'll drop all the prices to clear out old inventory. Maybe force nVidia to drop as well.
That's what I want to hear! Flagship GPUs should be like this.
FYI: HBM is faster than GDDR5
here is a bunch of HBM presentations

a 4096-bit HBM can vary on bandwidth depending on memory freq so
without futher ado i give to you this eerm nvidia presentation
The cheapest new 290X is still $500 here.
Now, what really matters to me is that the after market water blocks and component make up allow for noise free (and I mean coil whine) gaming.
The 7870 XT (Tahiti LE) has a stock HD 7950/7970 PCB and does not exhibit coil-whine. I have this overclocked at 1,250 core.
I know the 970's have had some issues with whine as well. My point is, a nicely built card minimises coil whine but I assure you, it's far more common than the percentage you're stating, it's just a nuisance to varying degrees to different people. Both Nvidia cards and AMD cards get it.
Judging by all the pre-leaks, the 390X looks to be the card AMD have sorely needed. Even if the leaks are lies, it's enough to stop me buying a Titan X until I see the 390X. But if the 390X with 8Gb (and 2 8pin power connectors) is as much as a 12Gb Titan X, it will be a hard call.
That translates to "the card will overheat and throttle just like the 290x, but it will last long enough for benchmarks to finish so the reviews look better".
I think it all depends on how aggressive Nvidia is with Titan X pricing.
Double standards FTW.

AMD has charged too little for their chips for too long and it may very well bankrupt them if they don't stop it.
I hope that helps. :)
