Polaris Evolved - AMD's Tease Before Vega Next Month

By Anthony Garreffa from Apr 18, 2017 @ 8:00 CDT

RX 580/RX 570 Tech Specs


The difference between the Radeon RX 580 and the RX 570 is that AMD has sliced off four compute units (36 vs. 32), and 256 stream processors (2304 vs. 2048), and with a drop to the GPU base and boost clocks of around 100MHz, respectively - we have 6.17 TFLOPs and 5.1 TFLOPS of performance for the RX 580, and RX 570 respectively.





There are 16 more texture units on the RX 580 with 144 TMUs total, and 128 TMUs on the RX 570. We have a peak texture fill rate of up to 193 GT/s on the RX 580, while the RX 570 manages up to 159 GT/s. There are 32 ROPs on the RX 580 and RX 570, while peak pixel fill rate is up to 42.9 GP/s on the RX 580, and slightly slower on the RX 570 with 39.8 GP/s.




There is 8GB of GDDR5 available on the Radeon RX 580, while 4GB is available on the RX 570. 1080p gaming won't really push past 4GB, so the RX 570 is suited for up to 1080p gaming at 60FPS, while the RX 580 has 8GB and can be pushed into the 1440p 60FPS category. The 8GB of GDDR5 on the RX 580 has 256GB/sec of memory bandwidth, while the RX 570 has 224GB/sec, with both cards on a 256-bit memory interface.




AMD has the Radeon RX 580 set with a 185W TDP, while the RX 570 has a TDP of 150W. These numbers are quite high, considering NVIDIA's GeForce GTX 1080 is massively faster and has a 180W TDP. It beats the pants off of everything AMD has on the market right now, and while the Radeon RX 580 is a mid-range graphics card, it uses more power than the GTX 1080.




Radeon Chill will bring those numbers down, so expect a deeper dive into power consumption numbers and temperatures in the coming weeks. I've just purchased a thermal imaging camera, so we can start playing with thermal content in our upcoming graphics card reviews.
