Sapphire RX 570 Pulse Review

Rating: 8.5.

Having reviewed a couple of new AMD RX 500-series cards on launch day, we are supplementing those initial reviews with a look at Sapphire’s RX 570 Pulse 4GB card. The Pulse series is a new addition to Sapphire’s line-up, and essentially it is meant to offer the quality of Sapphire graphics cards at lower prices by ditching some of the extra, potentially superfluous features that the Nitro+ family include.

Personally I think this is very smart, as if Sapphire can deliver a strong graphics card that performs well and costs less than the competition, then it is surely onto a winner. In this review, we benchmark the Sapphire RX 570 Pulse 4GB against the competition in a number of the latest games and synthetic tests before offering our final verdict.

This Sapphire RX 570 does come with a slight factory overclock, at 1284 MHz (a 27 MHz increase over reference speeds).

It is also worth noting some of the features that the Pulse cards do not have. When compared to the Nitro+ series, features that are lacking include:

  • Extra LED fans
  • Dual-BIOS functionality
  • RGB Sapphire logo
  • NITRO Boost
  • NITRO FanCheck
  • NITRO CoolTech (NCT)
  • Robust VRM cooling

Clearly, the Pulse cards are designed to ‘just work’, so the performance of this RX 570 in games and benchmarks will go a long way to determining whether or not it is worth buying.

    Excellent review; and it would be nice to see you you could label the release year of the games you use for benchmarking, as point of reference as well.
