Sapphire RX 580 Pulse 8GB Review

Rating: 8.5.

Following on from our launch-day coverage of the RX 500-series, today we analyse another RX 580. This partner card from Sapphire comes attractively priced at £239.99 which could make it a very compelling option for those in the market for a new mid-range graphics card. It does sacrifice some extra features to meet this lower price-point – including RGB LEDs – but can its performance make up for the lost bling?

Launching alongside our review of the Sapphire RX 570 Pulse 4GB card is this review of the RX 580 Pulse 8GB. If you’ve come straight to this review, it is worth explaining a bit about the Pulse family. Essentially, it is a new product series from Sapphire that aims to keep the solid build quality and performance we expect from Sapphire cards, while ditching some extra, less necessary, features to keep the cost down.

This particular RX 580 partner card has received a modest factory overclock: up to 1366MHz boost, which is an extra 26MHz 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
