This happened! AMD announced the company's first graphics card from the new family of Polaris - we are talking about the model Radeon RX 480, which breaks the opinion of the average price segment. The premiere of the new card should happen as early as this month.
A new generation of graphics processors manufactured by technology 14 nm FinFET, and in addition, It uses a new version of the GCN architecture (Graphics Core Next). As a result,, through the use of lower process and additional improvements engineers "red", we can even count on a 2.8-fold increase in energy efficiency compared to the previous generation models.
Radeon RX 480 It based on the base GPU Polaris 10 of 36 computing units (WITH) - having regard to the existing building cores based on GCN architecture, be suspected, that in total they have 2304 stream processors and 144 texture units (each block consists of CU 64 units SP and 4 blocks TMU). Besides, on board were 4 or 8 GB GDDR5 256-bit, wherein the bandwidth is 256 Gb / s (as many, and that in a competitive model GeForce GTX 1070).

About the performance of the new card is not yet known too much, However, manufacturer boasted, the tandem Radeon RX 480 ahead in games in DirectX mode 12 topovuyu map rival - GeForce GTX model 1080.

Bibliography 480-TCA was equipped with a 2-slot cooling turbine, которая значительно выступает за плату. On the bar brought three outputs HDMI and one DisplayPort 1.4, and additional power sums only one 6-pin connector (Power consumption is estimated at 150 AT). Premiere Radeon RX 480 took 29 June .
