AMD AIBs Launch Radeon R9 390 with 4GB of VRAM
When AMD launched their R9 390 and R9 390X GPUs, the key change made in the core GPU design was the 8GB of GDDR5 memory on both of those products. That was 2x the size of their predecessors, the R9 290 and R9 290X.
At the time, AMD didn’t allow its board partners to sell versions of the R9 390 GPU with 4GB VRAM, although it was more in line to the memory requirements in current generation titles. Now, it appears that AMD AIBs have started selling 4GB versions – in China, at least.
Right now, Sapphire, PowerColor and XFX have released their cards and from the looks of it, the custom models, while featuring lower VRAM are just as fast as their full 8GB versions thanks to higher clock speeds compared to reference models.
The Sapphire Radeon R9 390 Dual-X OC comes with two fans and features 1010 MHz core clock and 5000 MHz boost clock. In addition, the card has a NITRO Booster profile saved in the BIOS that can be switched on through a click of a switch bringing it at par with a R9 390X in terms of performance. The 4GB R9 390 Dual-X OC costs about $309 at today’s exchange rates.
The PowerColor Radeon R9 390 4 GB comes with an enormous triple-fan heatsink and is clocked at 1010 MHz core and 6000 MHz memory clock. This card is priced at about $325.
Finally, we have the XFX Radeon R9 390 Black Edition which looks similar to the 8GB R9 390 with clock speeds of 1015 MHz for the core and 6000 MHz for the memory.The card retails for about $305.
Currently, there are no details about whether any of these card will ever make their way to the EU or United States, but they would certainly give a tough competition to the GeForce GTX 970.
