The Radeon RX 580 2048SP is a graphics card by AMD, launched in October 2018. Built on the 14 nm process, and based on the Polaris 20 graphics processor, in its Polaris 20 XL variant, the card supports DirectX 12.0. The Polaris 20 graphics processor is an average sized chip with a die area of 244 mm² and 5,700 million transistors. Unlike the fully unlocked Radeon RX 580X, which uses the same GPU but has all 2304 shaders enabled, AMD has disabled some shading units on the Radeon RX 580 2048SP to reach the product's target shader count. It features 2048 shading units, 128 texture mapping units and 32 ROPs. AMD has placed 4,096 MB GDDR5 memory on the card, which are connected using a 256-bit memory interface. The GPU is operating at a frequency of 1168 MHz, which can be boosted up to 1284 MHz, memory is running at 1750 MHz.
Being a dual-slot card, the AMD Radeon RX 580 2048SP draws power from 1x 8-pin power connectors, with power draw rated at 150 W maximum. Display outputs include: 1x DVI, 1x HDMI, 3x DisplayPort. Radeon RX 580 2048SP is connected to the rest of the system using a PCI-Express 3.0 x16 interface. The card measures 241 mm in length, and features a dual-slot cooling solution.
