Noticed yesterday by Heise.de, AMD has silently lowered the specs of the Radeon RX 560 to embody components with 14 CUs (896 Stream Processors), permitting them to be bought alongside normal 16 CU (1024 SP) components. The web impact of this alteration is that it permits Radeon RX 460-level merchandise to be bought as Radeon RX 560 playing cards.
With the RX 500 sequence Polaris household refresh, AMD primarily based the Radeon RX 560 on a totally enabled Polaris 11 GPU, that means all 16 of its CUs have been lively. Against this, AMD by no means shipped a totally enabled Polaris 11 half beneath the 400 sequence (excluding the Macbook Professional particular Radeon Professional 460), so the RX 560 was a notable step up from the 14 CU Radeon RX 460. And whereas the logistics of chip binning meant that AMD by no means stopped producing 14 CU GPUs, as soon as AMD did decide to promote a 14 CU half beneath RX 500 sequence lineup, it was launched because the regionally-limited RX 560D.

Nonetheless because it seems, in some unspecified time in the future just lately up to now, AMD has additionally authorized promoting 14 CU components as normal RX 560 playing cards. As found by Heise.de, someday throughout the previous few months the Radeon RX 560 product web page on AMD's web site was silently modified to incorporate the lowered 14 CU specs, with July nonetheless itemizing "16 CUs" solely. The web page doesn’t notice any change and nonetheless lists four/18/17 as the total launch date, so wanting understanding what to search for, the lowered specs are virtually a footnote.

The consequence of this alteration is that AMD and its companions can now market and ship lower-performing graphics merchandise labelled beneath the identical "RX 560" branding. And actually they look like doing so proper now, not solely in an OEM context by way of a presently transport PC as famous by Heise.de, but in addition playing cards from AIB companions. Sapphire RX 560s now have a separate 896 SP SKU half quantity (11267-18) however nonetheless branded the "Pulse Radeon RX 560," whereas ASUS has a "RX 560 EVO OC" 896 SP half. The PowerColor Purple Dragon RX 560 4GBD5-DHA product web page solely specifies a decrease clockspeed however its 896 SP depend was revealed on its Newegg itemizing.
Which brings us to the subsequent level of how this does translate by way of consumer-facing e-tailers. Amazon is immediately promoting each ASUS playing cards with out SP counts and solely referring to the GPU as RX 560 EVO, whereas Amazon UK is promoting the Sapphire card with none indication of 14 CUs. Moreover, Newegg is immediately promoting three 896 SP RX 560s, with the SP depend within the description: the PowerColor Purple Dragon 4GBD5-DHA (and the 4GBD5-DHAM brown field variant), together with the ASUS ROG Strix EVO Gaming OC. Primarily based on itemizing launch dates, this 896 SP RX 560 scenario has existed since a minimum of the start of October.
Placing this into efficiency numbers, in a closely compute or texturing-limited state of affairs, these lowered specs would enable for playing cards round 12% slower than playing cards constructed to AMD's unique specs. In impact, AMD is now capable of ship the lower-performing RX 460-like playing cards, however has achieved so in a really non-transparent, consumer-unfriendly method.
Now it needs to be famous that rebrands like this should not unusual with OEM components and the lowest-end retail SKUs, and that goes for each NVIDIA and AMD. OEM playing cards specifically are sometimes used to burn off extra chips or different stock that's simply sitting round. What’s atypical right here is that it seems that AMD has silently swapped out the specs of a mainstream ($100+) retail product; one that’s already transport. And if what we're noticing right here with AIB companions follows, then the change is certainly immediately linked to near-silent downgrades, albeit slight, of graphics components that customers would in any other case imagine are higher-performing.
We’ve got reached out to AMD for any clarification, however we’ve not heard again from them as of press time.
