AMD has quietly launched a Radeon RX 580 GPU with a reduced number of stream processors. The new product is called the Radeon RX 580 2048SP and, as the name suggests, it has 2048 stream processors, down from 2304 SPs on the original product. The Radeon RX 580 2048SP is currently available only in China and it is unclear whether the product will be sold in other countries as well.

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.

This is not the first time when AMD revises specs of its already launched products. Last year the company let partners to sell Radeon RX 560 products with 896 stream processors, down from 1024 SPs inside the original GPU. Back then the company explained that graphics processors with lowered specs enable its partners to sell more graphics cards and offer a better choice to their customers. At the time the Radeon RX 560D with 896 SPs was an entirely new product sitting above the Radeon RX550 - this time however the Radeon RX 580 2048 SPs is essentially the Radeon RX 570 with slightly higher boost clocks.

    Would it really have been so hard to call it RX 575? Reply

    Maybe '575' is an unlucky number in China. Reply

    Nobody's gonna pay you a dime for that! But the guy who came up with Radeon RX 580 2048SP got paid, a bonus and a promotion. Reply

    I calculated SPs*(base clock+boost clock) as an approximate measure of performance. If it was a linear scale, this should be called the RX 570.7848909! Even "RX 571" would be overselling it. Reply
