AMD has unveiled the specifications of both the recently announced Polaris 10 and Polaris 11 GPUs. As one might have already known, AMD’s Polaris 10 GPU will be powering the Radeon RX 480 graphics card. Meanwhile, Polaris 11 will most probably be used inside the RX 460 instead. Despite this, there’s still no information regarding which Polaris GPU will be used for the RX 470.
That aside, AMD’s Polaris 10 GPU will come with 36 CUs (Compute Units); which translates to a stream processor count of 2304. In addition, the GPU is also said to have a clock speed of 1,266MHz as well as a FP32 (single-precison floating point) performance of more than 5 TFLOPs. It’s worth noting that this GPU comes with a memory Bit-rate of 256-bit. Knowing that the RX 480 comes with all of these specifications means that AMD has decided to equip the graphics card with a full, non-altered Polaris 10 GPU.
Polaris 11 meanwhile, has 16 CUs (Compute Units); which is equivalent to 1024 stream processors. Unlike the Polaris 10 GPU, Polaris 11 will come with more than 2 TFLOPs (but less than 5) of FP32 performance and it will ship with a memory Bit-rate of 128-bit. Unfortunately, the clock speeds of this GPU is yet to be announced by AMD.
Both Polaris 11 and Polaris 10 GPUs will come with 4K HEVC Encode and Decode. In addition, AMD’s newest GPUs will also feature the 4th Generation Graphics Core Next microarchitecture. Interestingly, both GPUs are said to have up to 2.8x better performance per watt improvement over their respective predecessors.
