Rumor has it that the launch of AMD’s first Radeon 500 series cards, the Radeon RX 580 and RX 570, might face a short delay. Earlier, the cards were said to be launching on April 4, but a new report from MyDrivers suggests that they are now delayed till 18th of April.
Both the Radeon RX 580 and RX 570 are reportedly based on the Polaris 10 GPU which powers the current Radeon RX 480 and RX 470 cards. Meaning, we’re not going to see anything new in terms of the architecture or IPC (Instructions Per Cycle) improvements. Though, the rumors point towards a more refined process which could result in slightly better clock speeds and TDPs.
In addition to the Polaris 10 based rebrands, AMD is also expected to release the Polaris 11 based Radeon RX 560 that would effectively replace the RX 460. We’ve also heard rumors about the Radeon RX 550 which is said to utilize the new Polaris 12 graphics core, but its specs aren’t detailed yet.
AMD Radeon RX 580, RX 570 and RX 560 Specs (Rumored)
The Radeon RX 580 will be more of a higher clocked custom variant of the Radeon RX 480. The card could feature 2304 stream processors, 144 TMUs and 32 ROPs. It is expected to be running at 1340MHz boost clock to deliver 6.17 TFLOPs of compute performance.
The card will have up to 8GB of GDDR5 VRAM clocking in at 8.8GHz, across a 256-bit bus interface. Memory bandwidth will also remain the same, that is 256GB/s for the 8GB model. You can expect the 8GB Radeon RX 580 to priced lower than its predecessor, around $199.
The other Polaris 10 based rebrand, the Radeon RX 570, will sport a cut-down graphics core as the current RX 470. It would be clocked at 1244MHz boost, delivering the compute output of 5.10 TFLOPS.
As expected, the card will come with up to 8GB of GDDR5 memory, but it will be clocked at higher 7.0GHz frequency, to yield a total of 224GB/s bandwidth. It is expected to carry a price tag of around $149.
Finally, we have the Radeon RX 560. Unlike the RX 460 which came with a locked core, 560 would feature a full-fat Polaris 11 GPU. It will run at a boost clock of around 1287MHz, with the compute output rated at 2.63 TFLOPS.
In terms of memory, the RX 560 would have a 4GB of GDDR5 VRAM spread on a 128-bit bus interface. You may grab the card under $100.
That’s all we know about the upcoming Radeon 500 series graphics cards. AMD’s next generation Radeon Vega GPUs won’t be part of this 500 series lineup; instead they will be released under the brand-new Radeon RX Vega series.
