AMD announces Radeon RX 460, RX 470, and RX 480M
AMD intends to make power-efficient gaming systems at affordable prices and its Polaris 10 architecture is looking ready to pave the way. The RX 480 made its debut at Computex and it is already receiving praise for its raw 5 TFLOPS of performance and $200 USD price point with availability by the end of this month. Now, Polaris 11 has also been announced and will make its debut in the mobile sector as the RX 480M.
Polaris 11 vs Polaris 10
The Polaris 10 architecture houses 36 CU (Compute Units), 2304 shaders, and a 256-bit bus to constitute one of AMD's most powerful offerings as of 2016. On contrast, Polaris 11 will be slimmed down to only 16 CU, 1024 shaders, and a 128-bit bus for a theoretical performance of 2 TFLOPS. Both versions of Polaris will have native support for DisplayPort 1.4 and HDMI 2.0b for decoding HDR video.
Radeon RX 470 vs. Radeon RX 460
Like the Radeon RX 480, the RX 470 will be based on the Polaris 10 architecture. According to AMD, the RX 480 will run games at 1440p60 while the RX 470 will be ideal for 1080p60 gaming. According to WCCFTech, the RX 470 will be available in 4 GB and 8 GB GDDR5 VRAM variants and will have slower RAM at 7 GHz and only 2048 shaders. Thus, its TDP is expected to be 110 W compared to 150 W for the RX 480.
Meanwhile, the RX 460 will be based on the weaker Polaris 11 with an expected TDP of 75 W. Versions will likely come with either 2 GB or 4 GB GDDR5 RAM. The RX 480, RX 470, and RX 460 should all be available by the end of this month with prices ranging from $100 USD to $240 USD. Official prices in Europe have not yet been announced.
As for the notebook RX 480M, the source is claiming a 35 W TDP and a Polaris 11 architecture. It is expected to have 16 CU and a 14 nm FinFET manufacturing process. Preliminary scores in 3DMark 11 and Fire Strike are 7200 and 4070 points, respectively. Notebooks sporting the RX 480M have not yet been announced.
