AMD updates Crimson ReLive drivers to support Radeon RX 580 and 570

In essence, RX-500 is a refresh of the existing RX-400 series, which is something not so uncommon in AMD's strategy.

Here's a look at the technical specs for the Radeon RX 570 and RX 580 (we reviewed Sapphire's take on the latter). The RX 580, which is the most powerful card in the mid-range series, will be able to achieve this, according to AMD. Unlike the Radeon RX 480, which launched with 1120MHz base and 1266MHz GPU Boost clocks, the Radeon RX 580 will work at 1257MHz base and 1340MHz GPU Boost clocks, although AMD AIB partners will push that even further. We don't know how much headroom is left in these chips, but we're fairly certain tapping it will burn larger and larger amounts of power relative to measured performance improvement. Anandtech's review implies that the RX 570's power curve is a bit better than the RX 580s, meaning the gap between the stock RX 470 and a custom, overclocked RX 570 is about 10 percent smaller than the equivalent gap between a stock RX 480 and an overclocked RX 580. This is the gist and nature of the changes.

It seems AMD is not pulling out all the stops like it did with the Ryzen CPUs lately. Meanwhile, RX 400 series owners need not pay attention as the performance gain here is not worth upgrading to. They are not based on the highly-anticipated Vega architecture but come based on Polaris architecture.

Radeon WattMan may fail to apply settings on some Radeon R9 390 series graphics products.

I was super excited when my contact from the AMD PR and Marketing team emailed me about a new video card release a few days ago, and asked if I would agree to an NDA. At the time of writing, Sapphire confirmed the release of two RX 580 models, including a Limited Edition and a single SKU for the RX 570.

Word has it that the Red Devil will feature 1400+ MHz clocks.

Both the 1060 and the RX 580 ran Ashes of the Singularity at 51.7 fps at 1080p, and came within one tenth of a frame (45.7 fps on the 1060, 45.6 fps on the RX 580) at 1440p. Memory is the same 4/8GB 8Gbps GDDR5 configuration with 256-bit memory bus width. The best one of them all is the RX 580 which is the upgrade to the last year's RX 480.

Under the hood, the Radeon RX 570 sees very slight increases to its memory bandwidth, peak texture fill-rate, and peak compute performance, but the real draw here is the clock speeds.

Livestreamers will also benefit from a new dedicated encoding block created to take stress off the GPU. That's a 74MHz increase. The TDP has gone up from 150W to 185W.

The RX 570 is positioned between the upper-end of the GTX 1050 Ti's price range and the bottom of the GTX 1060 3GB's. The flip side is that these GPUs do burn more power.
