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.

    China has very poor consumer protection laws and more important lousy enforcement. These chips probably would be binned as straight 570 if they were headed to US but channels in China can and will market them as 580 with zero chance of getting sued.

    This is why we need real competition in the tech sector. Clearly, Nvidia and AMD are not consumer friendly.
  • Oxford Guy - Monday, October 15, 2018 - link

    Monopolies and duopolies reign.

    Consumer operating systems = Windows and MacOS
    Consoles (non-portable) = Microsoft and Sony
    GPUs = Nvidia and AMD
    CPUs = Intel and AMD
    Consumer computer hardware (non-portable) = x86

    et cetera

    Some more:

    phones: Android and iOS
    search: Google and Bing

    It seems like everyone is satisfied with letting one or two companies control everything. This is not a recipe for consumer-friendly practices!

    "It seems like everyone is satisfied with letting one or two companies control everything" you must be a seriously dim bulb if you think that's the reason why there are monopolies and duopolies in industries that require massive amounts of capital for a company to even attempt to be competitive.

    Pot calling kettle black. If consumers didnt like it, they would be jumping on any new company entering the market, even if the final product is riddled with bugs and production issues. Case in point tesla.

    News flash: the "mindless consumer drone" stereotype exists for a reason. Many consumers will simply buy what is prettiest, from a brand they know. How many people continued to buy samsungs despite their atrocious skin and performance during the earlier galaxy era? How many people continue to buy HP laptops despite their quality being absolute garbage? People buying chryslers despite atrocious reliability, buying ford focus cars despite a faulty gearbox, ece.

    If the consumer doesnt support it, the company will go under, no matter what "it" is. And if consumers are content with the status quo, they wont jump on a new company, and you end up with a duopoly. Again, case in pint, windows phone. WP was superior to iOS and android from both a ease of use and capability standpoint, yet they floundered and went under, most consumers just bought the next iphone or samsung phone.

    Looks like AMD's GPU division is circling the drain.

    I've heard that many times before, and then look at Zen. Never say never.

    Instead of cynical rebranding, how about a GPU that's even vaguely competitive with Nvidia's offerings?
