noticed a number of AMD's board partners have cut the memory capacity of the Radeon R9 390 in half to achieve lower price points. These new models feature 4GB GDDR5 memory, but so far they're only available in the Asia Pacific market. Sapphire, XFX and PowerColor have already launched versions with custom coolers and overclocked clockspeeds.
Some cards from Sapphire, PowerColor and XFX have already been released and from the looks of it, these custom models, while featuring lower VRAM are just as fast as the Radeon R9 390X due to higher clock speeds compared to reference models and boosted profiles saved within the BIOS. The Sapphire Radeon R9 390 Dual-X OC comes with 1010 MHz core clock and 5000 MHz boost clock. The memory clock means that the card will run at 320 GB/s compared to 384 GB/s bandwidth offered on the 8 GB variant but a NITRO Booster profile saved in the BIOS of the card can be switched on through a click of a switch that will put the card next to a R9 390X in terms of performance. The PowerColor Radeon R9 390 4 GB is a high-end model that comes with a triple-fan cooler and is clocked at 1010 MHz core and 6000 MHz memory clock. Finally, we have the XFX Radeon R9 390 Black Edition which comes with clock speeds of 1015 MHz for the core and 6000 MHz for the memory.
