AMD has finally confirmed the specifications of Polaris 10 and Polaris 11, two new silicon based on Polaris architecture manufactured under the manufacturing process of 14nm FinFET. Now we know that, Polaris 10 has 36 Compute Units (2304 Stream Processors) compared to 16 CUs (1024 Stream Processors) found in Polaris 11.

Respective form, the silicon is attached to a memory interface of 256 and 128 bit with floating-point performance of 5 TFLOPs and 2 TFLOPs. Both share the ability to encode and decode 4K videos with DisplayPort 1.4 / 1.3 HDR interface and both improved by up to 2.8 times the performance per watt consumed if we compare it with their predecessors.

Radeon RX 480 performance in Steam VR

Finally we have new benchmarks of AMD Radeon RX 480 8 GB GDDR5 in Steam VR. The new GPU scored 6.3 points in the Steam benchmarking software. To be exact, 6.3 points are almost twice the graphics performance provided by its predecessors, the Radeon R9 380 (3.6 points). With that score, the Radeon RX 480 would have a performance similar to Radeon R9 390.


And finally, as little more, it reminds us new members of the family, the Radeon RX 470 (perfect for playing games at 1080p resolution) and Radeon RX 460 (cool and efficient for eSports games). A Radeon RX 470 (110 watts) would be 57 percent faster than a Radeon R9 270X (180 watts) in Fire Strike test from 3DMark and it will be 64 percent faster in the Ashes of the Singularity, by 117 per cent in Hitman and by 59 percent in Overwatch.

The Radeon RX 480M (35 watts) offers a 26 percent better performance than the Radeon R9 M280X (82 watts) in 3DMark 11 and 16 percent more points in 3DMark Fire Strike.
