AMD is expanding its Radeon mid-range graphics cards by releasing a 4GB variation of the Radeon R9 390 through its AIB partners Sapphire, XFX, and PowerColor (via Chinese sites EXPreview and JD.com). The company hopes that the 4GB version, a variant on the 8GB original, will help it compete against NVIDIA’s GeForce GTX 970 and below.
The new Radeon R9 390 variants sport the Grenada PRO GPU and 4GB GDDR5 memory. The 4GB could be considered R9 290 rebrands were it not for 10% faster clock speeds.
Sapphire Radeon R9 390 4G D5 Platinum Edition OC
Sapphire’s R9 390 is overclocked by 10MHz, has a triple-slot Dual-X cooler, and features a backplate and reference PCB.
XFX Radeon R9 390 4GB ‘Black Wolf’ Double Dissipation
The XFX ‘Black Wolf’ has been overclocked by 15MHz, features a custom PCB, and a Double Dissipation cooling system.
PowerColor ‘Dataland’ Radeon R9 390 4GB
PowerColor’s ‘Dataland’ card is the first triple-fan 4GB R9 390, while its cooling is so efficient its fans will not engage until the GPU hits temperatures of 62oC.
EXPreview has put the cards through their paces, comparing them to the similar R9 290, showing the new variants to be up to 10% faster the old card.
There is no news yet on international release dates for the Radeon R9 390 4GB variants.
