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.

    Only for those that preordered before launch.

    Boo Hisss. Even if we assume that manufacturers and vendors will consistently include the 2048SP part of the name it's needlessly confusing and I hate it when GPU vendors do this. Nvidia is just as guilty as AMD and I hate it.

    Also I think the prices in the table are wrong. The launch price of the 580 wasn't $99. $199 for the 4gb version maybe or maybe in a currency other than USD,

    This is very likely a china-only product.

    Nah, Nvidia is only guilty of rebranding 1 or 2 generations back with the current nomenclature for super cheap cards. GeForce4 MX, anyone? I don't really know which is worse, because both pollute their own namespaces, though I think it may be AMD's flat out reuse of names that's definitely going to cause more consumer confusion.
  • kpb321 - Monday, October 15, 2018 - link

    Yes because NVIDIA is completely blameless with the 1050 2gb/3gb or 1060 3gb/6gb cards being differing configs for the different memory sizes. Wikipedia even list a 1060 5gb with yet another config.

    you forgot the 1030 GDDR scandal.

    So... its a 570 with a slightly faster boost clock?
    When are they going to release some real GPUs?

    Most card makers were already making this, they call it a 570. Most of them only use AMD's clocks as a starting point.

    what a STUPID MOVE for AMD to allow/do because we just KNOW that various AIB or at least resellers and how they did not properly label RX 560 with te 16CU (full fat) or the cut down 14CU (1/2 fat?) and yet charged the same #$%^#% price (Asus, MSI looking directly at you)

    If this "cut down" RX 580 is basically identical to an RX 570 (but a wee touch higher boost) then it darn well better be priced like a 570 is (should have been) $169 USD for the 4gb ~$220 for 8gb

    Nothing worse then AIB (or sellers) charging same as if not more then the "big brother" or identically pricing the RX 570 and 580 when they should not be doing so.

    so much for the "price drop incoming" have read about here there and everywhere since March of this year, RAM price was supposed to drop around the same time frame (though it has not)

    anyways....I am with others on this, if they want to do a "cut-down" RX580 that is virtually identical to 570s, they should have called it 570 something, not 580 with less CU, or better yet, just call it a damn 570 because that is what it is, 40Mhz on "boost" means previous little when some cards never manage to get it there in majority of use cases because of poor thermal cooler design (Ahem Armor MK1)

    I do not think I ever seen once a 4gb RX 570 priced at $169 even within first week or 2 in US, they seemed to hit $230+ real quick however, and the 8gb models ~$245+ (570 or 580) the 580s $229 LOL...try $250+ unless you got "day 1" and "lucked out" or bought from Ebay or something...
