Spotted yesterday by Heise.de, AMD has silently lowered the specifications of the Radeon RX 560 to encompass parts with 14 CUs (896 Stream Processors), allowing them to be sold alongside standard 16 CU (1024 SP) parts. The net effect of this change is that it allows Radeon RX 460-level products to be sold as Radeon RX 560 cards.

With the RX 500 series Polaris family refresh, AMD based the Radeon RX 560 on a fully enabled Polaris 11 GPU, meaning all 16 of its CUs were active. By contrast, AMD never shipped a fully enabled Polaris 11 part under the 400 series (excluding the Macbook Pro specific Radeon Pro 460), so the RX 560 was a notable step up from the 14 CU Radeon RX 460. And while the logistics of chip binning meant that AMD never stopped producing 14 CU GPUs, once AMD did opt to sell a 14 CU part under RX 500 series lineup, it was introduced as the regionally-limited RX 560D.

However as it turns out, at some point recently in the past, AMD has also approved selling 14 CU parts as standard RX 560 cards. As discovered by Heise.de, sometime within the past few months the Radeon RX 560 product page on AMD's website was silently changed to include the lowered 14 CU specifications, with July still listing "16 CUs" only. The page does not note any change and still lists 4/18/17 as the full launch date, so short of knowing what to look for, the lowered specifications are practically a footnote.

The consequence of this change is that AMD and its partners can now market and ship lower-performing graphics products labelled under the same "RX 560" branding. And in fact they appear to be doing so right now, not only in an OEM context via a currently shipping PC as noted by Heise.de, but also cards from AIB partners. Sapphire RX 560s now have a separate 896 SP SKU part number (11267-18) but still branded the "Pulse Radeon RX 560," while ASUS has a "RX 560 EVO OC" 896 SP part. The PowerColor Red Dragon RX 560 4GBD5-DHA product page only specifies a lower clockspeed but its 896 SP count was revealed on its Newegg listing.

Which brings us to the next point of how this does translate in terms of consumer-facing e-tailers. Amazon is directly selling both ASUS cards without SP counts and only referring to the GPU as RX 560 EVO, while Amazon UK is selling the Sapphire card without any indication of 14 CUs. Additionally, Newegg is directly selling three 896 SP RX 560s, with the SP count in the description: the PowerColor Red Dragon 4GBD5-DHA (and the 4GBD5-DHAM brown box variant), along with the ASUS ROG Strix EVO Gaming OC. Based on listing release dates, this 896 SP RX 560 situation has existed since at least the beginning of October.

Putting this into performance numbers, in a heavily compute or texturing-limited scenario, these lowered specifications would allow for cards around 12% slower than cards built to AMD's original specifications. In effect, AMD is now able to ship the lower-performing RX 460-like cards, but has done so in a very non-transparent, consumer-unfriendly manner.

Now it should be noted that rebrands like this are not uncommon with OEM parts and the lowest-end retail SKUs, and that goes for both NVIDIA and AMD. OEM cards in particular are often used to burn off excess chips or other inventory that's just sitting around. What is atypical here is that it appears that AMD has silently swapped out the specifications of a mainstream ($100+) retail product; one that is already shipping. And if what we're noticing here with AIB partners follows, then the change is indeed directly linked to near-silent downgrades, albeit slight, of graphics parts that consumers would otherwise believe are higher-performing.

We have reached out to AMD for any clarification, but we have not heard back from them as of press time.

Update (12/5/17, 6 p.m. ET): An AMD statement given to our sister site confirms the two RX 560 variants, and AMD also noted that AIB partners would be responsible for communicating a given RX 560 model's specifications.

Update (12/6/17, 2 p.m. ET): AMD has provided a full comment to us in regards to the situation:

It’s correct that 14 Compute Unit (896 stream processors) and 16 Compute Unit (1024 stream processor) versions of the Radeon RX 560 are available. We introduced the 14CU version this summer to provide AIBs and the market with more RX 500 series options. It’s come to our attention that on certain AIB and etail websites there’s no clear delineation between the two variants. We’re taking immediate steps to remedy this: we’re working with all AIB and channel partners to make sure the product descriptions and names clarify the CU count, so that gamers and consumers know exactly what they’re buying. We apologize for the confusion this may have caused.

    Will AT do a comparison of the two models? I’m curious if the 14 CU will maybe boost higher or more often and make up some of the difference. Reply

    There really is no point, the cut down shaders can't be overcome. An nvidia might be able to overcome the deficit since it can clock very high with minimal power increase - AMD parts don't have that ability. Reply

    There's no justification for it. The RX 560 was pretty universally faster than the RX 460 it replaced on account of the improved CU count. Moving back down to 14 CUs is just going to hurt performance.

    Some people claim this is "pulling an Nvidia," but this is probably the dumbest thing any of the tech companies has done in recent years, even if the impact is small.

    Don't forget the texture mapping units and Ram also got culled.

    It should have been named the Radeon RX 555.

    It seems even worse: the Sapphire Pulse Radeon RX 560 4GD5 contains both versions and the one with fewer CUs actually clocks lower (1226 MHz max vs. 1300 MHz) and has a lower power limit (75 W vs. 90 W). It's also got a lower memory clock (1500 MHz vs. 1750 MHz).

    This should really be a RX555 or RX550. Such desperate profit maximization seems not sustainable due to the reputation damage this might cause. Is that what we get now without Raja?

    They already have a 550. It should have been a 555 or (like some regions already have) a 560D. This is just the marketing department trying to figure out how to move chips with a defective CU or two. Honestly it was stupid of them to only sell a fully enabled chip for so long in most regions. Should have had a cheaper 14 CU (and lower power - no additional connector) model from the start. Reply

    This was probably done under Raja- article states weaker SKUs appeared at the beginning of October, and it takes time to make a decision, produce cards and distribute. Not to say that current AMD's response ('AIB partners would be responsible for communicating') is what consumers are looking for. Proper move would be to apologize and refund, before a lawsuit pops up. Reply

    Ok, thanks for the info. 560 is officially out of my shopping list. Reply

    I mean, NVidia had the 860M that was available in both Maxwell and Kepler versions, with dramatically different performance & power envelopes. Because reasons. Reply
