The Radeon RX 580 2048SP is basically the Radeon RX 570, but with a slightly higher boost clock and a different name. Compute performance of the Radeon RX 580 2048SP is listed as 5.1 TFLOPS, which is around 18% lower when compared to the Radeon RX 580. Just like the RX 570, the RX 580 2048SP cards come equipped with 8 GB of GDDR5 memory running at 7 Gbps, down from 8 Gbps on the original RX 580. Given how close specs of the RX 580 2048SP and the RX 570 are, it is unclear why AMD decided to release this “new” product with the RX 580 name, if only to confuse customers.
They did it before with the RX 560D ( 896 shaders ). They justified that one with a lower TDP

At the Chinese AMD website product pages have gone up, listing RX 580 having 2048 shader processors (Radeon RX 580 2048SP). And with an RX 580 that should be 2304 (which is the shader count for the RX 570). The product could be an OEM inclusion for system integrators though. If you focus on the specs, AMD seems to compensate a little bit with a high boost frequency listed at 1284 MHz vs 1244 MHz.
welcome to the chinese OEM market guys.. if you can't get X gpu to run on a low wattage PSU, just rebrand a lower TDP card as the higher TDP card and pocket some extra money in the process.
