Radeon RX 580 Sapphire Nitro+ Limited 8GB Game Requirement Analysis
First off we should point out that this is not the new AMD Vega graphics card line. The new AMD Radeon RX 500 series are an uprated version of the RX 400 series that they are replacing. This Sapphire RX 580 Nitro+ Limited graphics card is one of the two more powerful models from the new AMD Radeon RX 500 Series.
This RX 580 is the 8GB version and there is also the lower VRAM version, RX580 4GB available.
It equips a GPU codenamed Polaris 20 XTX, which has 2304 shader processing units, 144 TMUs and 32 ROPs.
The Radeon RX 580 Sapphire Nitro+ Limited 8GB central processing unit runs at 1257MHz and goes up to a top 1450MHz when in boost and turbo mode with the reference RX 580 card's boost is 1340MHz.
The GPU accesses a 8GB frame buffer of fast GDDR5, through a 256-bit memory interface, while the Memory Clock operates at 2000MHz.
The RX 580 8GB has a power TDP requirement of 150W. This means it will require at least a 500W PSU with one dedicated 8-pin connector.
Early benchmarks indicate that the AMD Radeon RX 580 8GB will be similar in performance to the Nvidia GTX 1060 in terms of gaming performance. This puts the RX 580 8GB about 8% faster than the model it replaced, the AMD Radeon RX 480 8GB. Comparing the RX 580 to RX 570 we see 1440p frame rates around 8-15% better with the RX580 version
The new Sapphire RX 580 Nitro+ Limited 8GB released on the 18th April 2017 and is best suited for resolutions up to and including 2560x1440. We recommend a high-end processor, like the new Ryzen R5 and at least 8GB of RAM for optimal gaming performance.
