While AMD’s Polaris household of GPUs have shocked us in a number of other ways, maybe probably the most spectacular facet has been their sheer longevity. First launched in 2016 as a 14nm replace to AMD’s GPU lineup, the GCN 3-derrived chips had been the spine of AMD’s mainstream video playing cards for over three years. And whereas it appeared like they’d lastly be put out to retirement with the launch of AMD’s 7nm Navi chips late final 12 months, Polaris is getting (one other) new lease on life, this time in a video card that’s being launched completely in China.
Dubbed the Radeon RX 590 GME, the brand new card isn’t receiving any formal fanfare for its launch. But AMD has added it to their product stack and up to date their Chinese-language pages accordingly.
So what’s Radeon RX 590 GME precisely? Unfortunately, as has turn into a recurring theme with China-only video playing cards, AMD and its companions are taking part in quick and unfastened with product names. Despite the identify, the RX 590 GME is notably slower than a correct RX 590 – about 10% slower, on paper – making it an RX 590-lite at finest, or extra pragmatically, a mildly overclocked RX 580.

In reality, whereas AMD hasn’t confirmed which particular Polaris GPU the cardboard is utilizing, the specs are nearer to an RX 580 (Polaris 20) than they’re an RX 590 (Polaris 30). The RX 590 GME ships with the RX 580’s 1257MHz base clock, however presents a 40MHz increased enhance clock, topping out at 1380MHz. The card’s (listed) specs are in any other case an identical to the 590/580, together with a full 36 CU configuration and 8GB of GDDR5 VRAM on a 256-bit bus that’s clocked at 8Gbps.
Otherwise, unverified third-party experiences have claimed that the cardboard is certainly utilizing Polaris 20, and these specs could be in line with that.
On paper, this places the height efficiency of the cardboard at simply lower than 3% forward of the RX 580, which has similarities to what AMD’s companions have beforehand been doing with their very own manufacturing unit overclocked playing cards. So the efficiency of the RX 590 GME is by and huge a recognized amount at this level, with the cardboard set to supply only a bit extra efficiency than AMD’s well-tenured RX 580.
The large query, in fact, is why AMD is releasing one other Polaris 10/20/30 card virtually Four years after the GPU was first launched. With earlier China-only playing cards this has been to fill particular market wants or to unload extra inventory, and each could also be an element right here. Within AMD’s product stack, RX 580-class playing cards in significantly are wholly redundant; the newer 8GB RX 5500 XT delivers 8%…
