A total of 6 Sapphire Radeon RX 500 series cards have been pictured. Of these, four are based on the full Polaris 20 XTX configuration and will be branded as the Radeon RX 580 series. The other two will use the Polaris 20 XL GPU that will be branded as the Radeon RX 570 series.

AMD Radeon RX 580 Graphics Card Specifications

The AMD Radeon RX 580 will be featuring a slightly higher clocked Polaris 10 GPU known as Polaris 20 XTX, 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. Radeon RX 580 will be available in both 8 GB and 4 GB GDDR5 memory variants, clocking in at 8.0 GHz along a 256-bit bus interface. The card will pump out 256 GB/s bandwidth. The reference models will feature a single 8-pin power connector so we can determine 8+6 or 8+8 pin configurations on custom models. Expect pricing to be around the same range as custom Radeon RX 480 models, around $229– $279 US.

Sapphire Radeon RX 580 Nitro+ and Pulse Series Cards

The Sapphire Radeon RX 580 Nitro+ will be available in both 8 GB and 4 GB variants. This model will come with a factory overclock and memory will be configured for 8.0 GHz. The card is expected to compete with the NVIDIA GeForce GTX 1060 updated models that come with 9.0 GHz memory.

In terms of design and assembly, the Nitro+ model features a matte black shroud with dotted textures on the front. The card features dual 90mm fans and the side of the shroud features an LED backlit RGB logo. The back of the card comes with a silver/black colored backplate that adds to the aesthetics and looks a lot neater compared to previous variants. Both cards are powered by an 8+6 pin power configuration. The cooling assembly is pretty strong on these models since they come with a dense aluminum fin array with 2 heatpipes extending from the GPU surface. Display outputs include 1 HDMI, 3 DisplayPort and a single DVI connector.

The Sapphire Radeon RX 580 Nitro+ LE is the same model but will be a limited edition design. No specs are available but it would feature slightly higher clock speeds. Finally, we have the Sapphire Radeon RX 580 Pulse that comes with 8 GB of memory. The Pulse variant is a slightly modifed variant of the Nitro+ featuring less heatpipes, a different backplate design and a single 8-pin connector for power delivery.

AMD Radeon RX 570 Graphics Card Specifications:

The second card to feature the Polaris 20 XL GPU would be the Radeon RX 570. This card would be similar to the RX 470, featuring a cut down Polaris core with 2048 cores. The card will additionally feature a clock beyond 1200 MHz boost which given the core specs are correct, would yield compute output of 5+ TFLOPs.

In terms of memory, we are looking at up to 8 GB of GDDR5 which will be clocked at 7.0 GHz clock to deliver 224 GB/s bandwidth. Power will be provided through a single 6-pin connector on the reference models so expect to see several 6+6 pin custom models.

The card will also be available in 4 GB models. Price wise, the card will cost around the $169-229 US price range.

Sapphire Radeon RX 570 Nitro+ and Pulse Series Cards

The Sapphire Radeon RX 580 Nitro+ will be available in 4 GB variants only. This model will come with a factory overclock and memory will be configured for 7.0 GHz. The card is expected to compete with the NVIDIA GeForce GTX 1060 3 GB models which will be shipping out with higher clock speeds relatively soon.

In terms of design and assembly, the Nitro+ model feature a matte black shroud with dotted textures on the front. The card features dual 90mm fans and the side of the shroud features a LED backlit RGB logo. The back of the card comes with a silver/black colored backplate that adds to the aesthetics and looks a lot neater compared to previous variants. The card is powered by a single 6-pin connector. The cooling assembly is pretty strong on these models since they come with a dense aluminum fin array with 2 heatpipes extending from the GPU surface. Display outputs include 1 HDMI, 3 DisplayPort and a single DVI connector.

The Pulse on the other hand is a very standard design. The variant is a slightly modified version of the Nitro+ featuring less heatpipes, a different backplate design and a single 6-pin connector for power delivery. Sapphire will also be offering the Radeon RX 550 and Radeon RX 560 series graphics cards in their lineup when launch approaches.
