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.


The Radeon RX 580 and Radeon RX 570 are based on the Polaris 20 graphics processor which has no major changes with respect to Polaris 10. This is the development of the AMD GCN architecture and its fourth implementation. The GPU counts 36 Compute Unit (CU) computational …

PowerColor Outs an Overclocked Radeon R9 270 OC Graphics Card

Along with other AMD partners, PowerColor has elaborated its own version of Radeon R9 270 adapter. The PowerColor Radeon R9 270 OC is differentiated from rival products by an improved cooling system and factory overclocked frequencies. Its release is scheduled for late November and the retail price won’t hit over $180.



To begin with, this graphics card is naturally based on AMD Curacao Pro GPU, developed under 28 nm technological process. It consists of 1280 current processors, 32 ROPs and 64 TMUs. The core runs at 930 MHz frequency and is able to gain 955 MHz frequency on overclocking. The incorporation of GDDR5 memory (2 GB) with 256-bit bus interface ensures some striking bandwidth of 180 Gb/sec; this provides for the support of gaming applications with high resolution. Memory chip operates at 1400 MHz nominal frequency but might gain the index of 5600 MHz of effective frequency on overclocking.


Cooling system, implemented within Radeon R9 270 OC, cannot be called …

Asus Introduces a New Powerful Motherboard Z87-A

The line of Haswell-compatible motherboards from Asus has been recently replenished with a new model – Z87-A. The new-comer is supposed to be the most ‘customer-friendly’ board, due to the correlation of incorporated facilities and price: based on the prime chipset (Intel Z87) on Socket LGA1150 platform, this board boasts an extreme functional combined with the price of $150 only. Thus, it might become a perfect solution for a powerful gaming PC.



Motherboard Asus Z87-A is elaborated in ATX form-factor and supports Intel Core i3, i5, i7, Pentium, and Celeron processors. Memory is represented by four DDR3 DIMM slots that are able to run at the maximal 3000 MHz frequency. Their overall capacity might achieve 32 GB. CPU power supply subsystem involves 8 phases; this is quite enough for a full-scale overclocking. Audio facilities are ensured by the integrated 7.1-channel Realtek ALC892 controller. Network facilities are backed by a separate gigabit Realtek 8111GR controller.
