Message Text: During E3, AMD unveiled the forthcoming Radeon RX 470 and RX 460 at E3, but also teased with Polaris and the release of two versions of it - the Polaris 10 and Polaris 11.

The larger Polaris 10 is a 36 CU (2304 SP) chip, which will produce more than 5TFLOPS and will have a 256-bit memory interface. This will power the forthcoming Radeon RX 480 video card.

The smaller Polaris 11 packs 16 CUs (1024 SPs). It is rated at more than 2 TFLOPs and it has a 128-bit memory bus. Most probably, the RX will be a Polaris 11 GPU.

AMD says that the Polaris 11 has a smaller die than the Polaris 10, so it will find its way to mobile GPUs as well, such as the Radeon RX 480M.

The company claims that the GPUs based on the new Polaris architecture offer approximately 2.8 times the power efficiency of the previous generation chips. In order to "prove" this performance gain, AMD presented two benchmarks, with impressive results:

In the first one (Polaris 10), AMD compared the Radeon RX470 (110W) and a Radeon R9 270X (180W), on a test system comprising an Intel i7 5960X @3.0GHz CPU and 16GB of memory. Here are the results:

3DMark FireStrike preset 1080p

  • Radeon RX470 score: 9090
  • Radeon R9 270X score: 5787

Ashes of the Singularity at 1080P High

  • Radeon RX470: 46fps
  • Radeon R9 270X: 28.1 fps

Hitman 1080P High:

  • Radeon RX470 : 60 fps
  • Radeon R9 270X: 27.6 fps

Overwatch 1080P Max settings:

  • Radeon RX470: 121 fps
  • Radeon R9 270X : 76 fps

For the Polaris 11 performance per watt tests, AMD compared the Radeon RX480M (16CUs, 32W) and a Radeon R9 280X (14CUs, 82W), on a test system comprising an Intel i7 i7-4600M, 8GB memory. Here are the results:

3DMark 11

  • Radeon RX480 score: 7200
  • Radeon R9 280X score: 5700

3DMark FireStrike

  • Radeon RX480 score: 4070
  • Radeon R9 280X score: 3500
