Sapphire has been selling Radeons as long as it has existed, and so it should come as no surprise that the company has the widest variety of graphics cards based on AMD's new Radeon RX 500 series, at least so far. The gemstone guys are making no less than nine cards for the new family, split between the classic Nitro+ series and the new Pulse series.
The new cards comprise five Radeon RX 580s and four RX 570s. Starting from the top, we have the Nitro+ Radeon RX 580 8GD5 Limited Edition. Sapphire says the GPUs that go on this model are hand-picked for high efficiency, and that they should be top performers for serious overclockers. The card will boost to 1450 MHz right out of the box, which is nothing to sneeze at.
Stepping down from those lofty heights, Sapphire is selling RX 580 cards with 4GB or 8GB of memory under both Nitro and Pulse branding. Both of the Nitro cards will boost their Polaris 20 GPUs to 1411 MHz. The Pulse cards are more conservative and will hang back at 1366 MHz. In both cases, the 4GB cards run their memory at 7 GT/s transfer rate.
For the slightly slower RX 570, Sapphire offers four cards. The Nitro+ Radeon RX 570 8GD5 model in particular is an unusual one, since it's an RX 570 with 8GB of memory. It will boost to 1340 MHz, as will the otherwise-identical 4GB version of that card. Meanwhile, the Pulse family offers a very similar RX 570 4GB card that boosts to 1284 MHz.
All of the above cards require a single 8-pin PCIe power connector and include a metal backplate. They also all share the same output cluster of one DVI port, two DisplayPort jacks, and a pair of HDMI ports. That could make them a better choice for VR users who wish to use an HDMI display alongside their headset.
Perhaps the most unique among Sapphire's new cards is the Pulse Radeon RX 570 ITX. This is the first card of its kind that we've seen from the RX 500 family. It packs an RX 570 GPU and its 4GB of memory into a card just 6.7" long that is satisfied with a six-pin power connector. Sapphire had to sacrifice some of the display connections to do so, leaving this card with one each of DVI, DisplayPort, and HDMI connectors.
As with the other RX 500 cards we've looked at lately, Newegg has all of Sapphire's finest up for sale already. That fancy Nitro+ RX 580 Limited Edition card rings in at $280. The standard Nitro+ RX 580 8GB is $250, and its Pulse cousin is $230. The 4GB cards come in at $220 for the Nitro+ and $200 for the Pulse. For the RX 570 cards, expect to shell out $220 for the Nitro+ card with 8GB of memory, $195 for its 4GB cousin, $180 for the Pulse version, and just $170 for the Pulse RX 570 ITX.
