The Second Generation of Polaris: Introduction to the Radeon RX 570 Using the ASUS ROG Strix Video Card as an Example

Currently, the situation with the total dominance of NVIDIA in the segment of top-end graphics solutions has developed. AMD is unlikely to present its progressive Vega accelerators shortly. But a series of mid-level video cards based on GPU Polaris has already been developed. Their second generation is presented, so let’s start studying the new products.


Polaris 20 Based Video Cards

The updated line of video cards includes four models: Radeon RX 580, Radeon RX 570, Radeon RX 560 and Radeon RX 550. They are direct successors of similar models of the RX400 series; in particular, the Radeon RX 580/570 replaces the Radeon RX 480/470. So, let’s consider the changes in the new video cards in this review.

SilverStone Debuts with SST-ST30SF Power Supply

SilverStone Technology has recently introduced its newest SFX power supply unit. Codenamed SST-ST30SF, it features 125x100x63.5 mm dimensions and weighs 800 g only. The unit is estimated for 300 W power and is capable to demonstrate more than 81% efficiency in 230 V networks. High efficiency level allowed the model to gain 80Plus Bronze certificate.



The most uncommon feature ascribed to SST-ST30SF is that it can operate in passive mode if thermal conditions allow. The unit is equipped with a fan of 80 mm dimensional type; it starts rotating only when the surrounding temperature reaches 55 degrees. This promotes for a considerable power reduction and practically silent work when the fan gets disabled. An average noise level on active operation makes up 18 dB.


SilverStone furnishes the new entry with a single +12V rail, estimated for 22 A current. In its turn, +3.3V rail is estimated for 21 A current, while +5V rail – for 20 A current. It should be noted that this unit …
