TUL Corporation, a leading and innovative manufacturer of AMD graphic cards since 1997, has released a whole new line of graphics cards that you have all been waiting for. All models are based on the latest GCN architecture to help deliver outstanding and extraordinary graphics performance and image quality. PCS+ R9 390X/390 both utilizes 8GB of GDDR5 memory with 2816 stream processors and ships with core clock speed at 1060MHz for the 390X, 1010MHz on the 390, and 1500MHz memory clock speed which is connected via a new high speed 512-bit memory interface. For enhancing power efficiency and preventing losses, Digital PWM solution is provided to work at a higher frequency in order to support fine tuning adjustment and low ripple at an output voltage. Moreover, the total of 8 phase (6+1+1) board design is applied to the models for power efficiency, stability, and delivering ultimate performance at OC mode.
PowlRstage increases the power up to 3-13%, features up to 1.0 MHz switching frequency, and supports efficient cooling ability. Also, the anodized back plate is attached to the back of the card to protect the components as well as helping to lower the temperature. The Efficient Trio Fan design with the Mute Fan Technology delivers intelligent fan controlling to provide noiseless environment as well as reducing the power consumption when the GPU temperature is lower than 60°C. For the best thermal solution, the card is equipped with pure copper GPU block to absorb heats from GPU. This block is connected to 3pcs of 6mm heat pipes and 1pc of 8mm heat pipe to help deliver heat to the nickel plated aluminum fins heat sink. These two models support AMD's newest technologies such as Virtual Super Resolution, FreeSync, Liquid VR, and 4K resolution.
