AMD has today announced two new additions to their Polaris graphics card line-up: the Radeon RX 470, and the Radeon RX 460. These new cards complete the Radeon RX graphics family, according to AMD, and slot in underneath the $200 Radeon RX 480.
The Radeon RX 470 is being positioned as the perfect card for 1080p gaming. Featuring a very similar design to the RX 480, and using a cut-down version of the same Polaris 10 GPU, AMD claims this card can play a wide range of modern titles at 1080p and 60+ FPS with anti-alisasing enabled.
Compared to the Radeon R9 270, AMD's three-year-old mid-tier card that launched at $180, the RX 470 offers between 1.5x and 2.4x the performance in AMD's collection of benchmarks. When we get our hands on the card, it will be interesting to see if these performance claims stack up.
The Radeon RX 460 is AMD's entry-level graphics card for e-sports gamers. Using a Polaris 11 GPU, the RX 460 is capable of playing popular e-sports titles like Dota 2, Rocket League and Overwatch at 90+ FPS on high quality settings at 1080p.
AMD is positioning the RX 460 as a graphics card with future-proof technologies. The graphics card comes with HDMI 2.0, DisplayPort 1.3 HBR with support for HDR, FreeSync, and support for modern APIs like Vulkan and DirectX 12. The card itself is barely longer than a PCIe 16x slot too, which will allow it to fit into very small form factor cases.
It also appears as though the RX 460 will make its way to mid-tier gaming laptops as a direct competitor to Nvidia's GeForce GTX 960M. AMD claims the RX 460 is 1.2x faster than the GTX 960M in Overwatch, with both GPUs featuring a similar TDP.
Specifications for the RX 470 and RX 460 are as follows:
|Peak TFLOPs||5.8 TFLOPs||4.9 TFLOPs||2.2 TFLOPs|

|Memory Bus Width||256-bit||128-bit|
|Memory Bandwidth||224 GB/s||211 GB/s||112 GB/s|
|Manufacturing Process||Polaris 10: 14nm||Polaris 11: 14nm|
|Typical Board Power||150W||120W||<75W|
Compared to AMD's previous-generation hardware, the RX 470 should pack performance just shy of the Radeon R9 390, while the RX 460 should sit between the R7 370 and the R9 370X. In both cases we're looking at significant power reductions: the R9 390 was a 275W card, and the R7 370 a 110W card.
AMD says the RX 470 should be available around August 4th, while the RX 460 will go on sale around August 8th. We don't have any pricing information just yet, although both cards should sit in the $100 to $200 price range. And as always, look for our full performance reviews of both cards around their respective launch dates.
