Sapphire launches Radeon R9 390 card with 4 GB VRAM
Sapphire has become one of the first companies to launch the new cut-down version of AMD’s Radeon R9 390 video card, namely a model that features 4 GB of GDDR5 memory on board.
The new card is called Sapphire Radeon R9 390 Platinum OC and as you can see from the name it features different clock speeds than the reference R9 390 video card but prepare to be surprised. The card uses an AMD Grenada Pro (Hawaii Pro) GPU with 2560 stream processors inside and a 512-bit memory bus but despite the OC moniker and the implemented massive Dual-X cooler the GPU clock speed has been increased from 1000 MHz to just 1010 MHz, while the installed GDDR5 memory has been slowed down from 6000 MHz to 5000 MHz. The new Sapphire card is 280 mm long and 45 mm high and includes a single 6-pin power connector, an 8-pin power connector, two DVI-D ports in the back, a single HDMI connector and one DisplayPort connector.
The price of the new card is unknown but it is definitely cheaper than R9 390 cards with 8 GB of memory on board.
