AMD Confirms Polaris 10 and Polaris 11 Specs, RX 470 3DMark Scores Show 2.8x Perf/Watt Increase
AMD revealed the Radeon RX 480 at Computex 2016 a few weeks back, and now more recently at PC Gaming Show during E3 2016, showcased the more mainstream based offerings, the Radeon RX 470 and RX 460. The entire Radeon RX 400 Series will be comprised of these three graphics cards which are based on the company’s next generation Polaris architecture.
Today, AMD has released a deck of slides revealing some details about these new Radeon cards. One of the slides also confirmed Polaris 10 and Polaris 11 specs, most of what we already know thanks to a series of leaks coming in for the past few months. According to the slide, the Polaris 10 features 36 GCN compute units (which translate to 2,304 shader processors), 256-bit memory bus, and more than 5 TFLOPS of compute performance. These specs match exactly with those of the Radeon RX 480.
On the other hand, Polaris 11 is a much smaller chip than the Polaris 10, with only 16 CUs, half the memory bus width, and over 2 TFLOPS of performance. The chip is likely to power the AMD RX 460, the smallest card in the series. AMD RX 460 features a single-slot card design with no PCI-E power connector, and an expected TDP of under 75W.
AMD further claims that the Polaris based GPUs will deliver 2.8 times the perf/watt of the previous generation, which it justified with some Radeon RX 470 3DMark Fire Strike benchmarking data buried in those slides. The company claims to have tested a 110-watt RX 470 versus a 180-watt R9 270X, with the results justifying that “2.8x perf/watt” figure.
The Radeon RX 470 scores an impressive 9090 in 3DMark Fire Strike 1080p, and manages an average 46 FPS in Ashes of the Singularity (1080p High preset), a 60-FPS average in Hitman (1080p High), and 121 FPS in Overwatch (1080p Max). Based on these RX 470 3DMark numbers, it will be safe to say that the RX 480 uses a cut down version of the Polaris 10 GPU.
As for the market positioning, AMD RX 480 will be sold as the most affordable premium VR and 1440p gaming solution. The RX 470 will target what AMD calls the “high definition” gaming (basically, 60 FPS 1080p), while the RX 460 will be geared towards MOBAs such as League of Legends.
The Polaris based Radeon RX 400 Series will address market segments ranging from a price point as low as $99 and as high as $299. AMD is set to launch the new cards on June 29th.
