The AMD Radeon RX 580 and Radeon RX 570 graphics cards have been pictured by Videocardz. The leak also confirms the specifications of the rebranded Polaris 10 based GPUs which will be available in mid April.

AMD Radeon RX 580 and Radeon RX 570 Graphics Cards Pictures Leak Out – Specifications Confirmed in GPU-Z Shots

Both graphics cards that were pictured are based on AMD’s Polaris 10 GPU core. The Polaris 10 core was introduced and launched last year and AMD is supposedly rebranding it as the Polaris 20 GPU. Process improvements have led AMD to deliver better clock speeds but these are more or less the same cards that you are able to purchase right now. The cards do feature a few cosmetic changes so let’s get in to the details.

AMD Radeon RX 580 Graphics Card Specifications:

The AMD Radeon RX 580 is expected to feature a slightly higher clocked Polaris 10 GPU. So this is similar to many custom variants of the Radeon RX 480 that are available on the market. The card will feature all 2304 stream processors, 144 TMUs, 32 ROPs.

The chip itself will be clocked at 1340 MHz boost to deliver 6.17 TFLOPs of compute performance. There will be 8 GB of GDDR5 memory onboard, clocking in at 8.0 GHz along a 256-bit bus interface. The card will pump out 256 GB/s bandwidth. Expect pricing to be slightly lower than the RX 480, around $199 – $249 US.

The sample pictured in the leak looks vastly similar to the current Radeon RX 480 graphics card. It comes with a plain shroud and follows the blower style cooling mechanism. The card packs a bulky metallic heat sink on the GPU and a VRM heatsink that offers better cooling. The board number is C940 so we can see that this is a new variant of the Polaris PCB. The sample was manufactured on March 3rd so it’s easy to tell that the card will be available really soon.

What’s interesting to see here that AMD actually put an 8-pin connector instead of a 6-pin. The reason to do so was not only to enable the card to feature higher clock speeds but also due to the early controversy where AMD RX 480 cards were pulling more power from the PCIe bus. As the 6-pin connector wasn’t providing enough juice to the VRMs and core to operate optimally.

AMD Radeon RX 570 Graphics Card Specifications:

The second card to feature the Polaris 10 GPU will be the Radeon RX 570. This card will be similar to the RX 470, featuring a cut down Polaris core with 2048 Cores. The card will additionally feature a clock speed of 1244 MHz boost which given the core specs are correct, would yield a compute output of 5.10 TFLOPs.

The card is also similar to the Radeon RX 470 and features the same Polaris 10 (cut down) variant which was featured on the previous model. The card lacks a DVI port, but instead features a HDMI 2.0 and three Display Port connectors. Although it lacks DVI, the placement for such ports is there allowing board partners to add it in their custom variants.

In terms of memory, we are looking at up to 8 GB of GDDR5 which will be clocked at a higher 7.0 GHz clock to deliver 224 GB/s bandwidth. Pricing wise, this card can hit around the $149 – $199 US price range.
