Radeon R9 390X and R9 390 to Feature Faster Memory, Core Over Predecessors
AMD's upcoming Radeon R9 390X and R9 390 performance-segment graphics cards reportedly feature higher GPU and memory clocks over the products they are a re-branding of, the R9 290X and R9 290, respectively. The 28 nm "Grenada" silicon they are based on, is identical to "Hawaii," down to the last transistor. This has been confirmed by leaked GPU-Z screenshots, which reveal the device-IDs of the two cards to be identical to those of the R9 290X and R9 290. Since the Device-IDs are the same, GPU-Z is reading the chip as "Hawaii." The code-name "Grenada" appears in the BIOS version string.
Unlike older, more blatant re-brands, such as GeForce 8800 GT to 9800 GT, AMD did drop in a few changes. To begin with, the memory amount has been doubled on both cards, to 8 GB. The memory clock has been increased from 1250 MHz (5.00 GHz GDDR5-effective), to 1500 MHz (6.00 GDDR5-effective), resulting in memory bandwidth increase to 384 GB/s, up from 320 GB/s. The core clock speed on the R9 390X is 1050 MHz (up from 1000 MHz on R9 290X); and 1000 MHz on the R9 390 (up from 947 MHz on the R9 290).

And now margin and tax away. $ 200 price is quite a lot of $ 100 for the development which is zero, $ 100 production -which is over kill. Poor customers! Crooks love to fuck us!
Card has demonstrated its strength in the 4k gameplay has a lot of usage and size compared to the GTX980. Well RAM is obtained at a better price. How much it actually benefits is the question. 8GB RAM R-9 290X was more expensive and equally effective as 4Gb RAM R9-290X.
How much has been changed on processor ,or was only the name change?
i have 7970 and 290x and 290x is much better so it will worth.
edit: keep an eye on this guys
Also streaming textures slows down performance linearly because it has to re-send data that the GPU doesn't have on every redraw, so the bigger the share, the longer the draw takes (and more time GPU spends doing nothing I might add.) I can't underestimate how much that destroys performance as it's many factors slower than dedicated memory.
Simple fact is that 4GB, is 4GB, is 4GB.
Grenada = Hawaii
Antigua = Tonga
Trinidad = Curacao = Pitcairn
Tobago = Bonaire
I'm not a fan of AMD's new tactic of giving old GPU's new codenames when they're rebranded. Also, as great as Pitcairn was, it has no place on a GPU lineup in 2015. A further cut down Tonga would have made more sense (though maybe not financially).
The current 390/X that have been show have improved cooler over there 290/X part.
i have a 390 so ... albeit the fact that i can't reach a stable 1500 on vRAM... (1050 core is stable but i keep it at 1000)
i could only run one heaven but it always hang up at the 25/26 scene xD
