ASRock Phantom Gaming X Radeon RX 590
Our meta review: The ASRock RX 590 gets good grades in general. Editors liked the form factor and the GPU boost clock. On the downside, the fans were a bit loud.
ASRock Phantom Gaming X Radeon RX 590 Prices
The RX 590, or Polaris 30 XT, is likely AMD’s final and most refined GPU based on the Polaris architecture. It is a followup of the RX 480 and RX 580, with the same 2,304 shaders, 144 TMUs (texture mapping units) and 32 ROPs (render output units). The chip differs from its predecessors in the manufacturing process, which is down to 12 nm from 14 nm, and 15% higher clock rates.
On top of the already-increased clock speeds, ASRock’s Phantom Gaming X Radeon RX 590 comes with the highest factory overclock (at launch).
ASRock Phantom Gaming X Radeon RX 590 Features
Most of the RX 590 graphics cards on the market, like the XFX Fatboy RX 590 and ASUS ROG Strix Radeon RX 590, the ASRock Phantom is overclocked. But unlike the competitors, ASRock has pushed the maximum GPU boost clock all the way up to 1591 MHz from the reference model’s 1545 MHz.

Other than the higher boost clock (and possible binning behind the consistently higher clock rate), the ASRock RX 590 comes with two fans like most of its competitors. A key difference from most, however, is that it will not occupy more than two PCI slots. ASRock’s official presentation:
Outputs: 1 x Dual-link DVI-D, 2 x HDMI 2.0b and 2 x DisplayPort 1.4.
Because of the improved production process and the resulting higher clock rates, graphics cards like the ASRock Phantom Gaming X Radeon RX 590 are about 10-15% faster than cards with the RX 580 in games and synthetic benchmarks. The ASRock card adds an additional 3% on top of this as a result of its factory overclocking. Compared to the Nvidia alternatives, any RX 590 is on average faster than an Nvidia GeForce GTX 1060, but usually slower than the newer GeForce GTX 1660 Ti and much less efficient.
System and PSU requirements
AMD recommends a 500 W power supply for the RX 590 (TDP is 175 W). The ASRock card requires one 8-pin PCIe power connector.
This card is featured as the fastest RX 590 in our guide from Q1 2019.
… with this excellent overall result, the ASRock Phantom Gaming X Radeon RX 590 8G OC graphics card receives our OCinside.de Purchase Tip Award 02/2019.
Performance wise it’s what I expected, with performance hovering just above the GeForce GTX 1060, but in most cases, it did outperform the GTX 1060.
ASRock’s Phantom Gaming X earns a value win against its Radeon RX 590 competition. But the faster GeForce GTX 1660 Ti and more affordable Radeon RX 580 steal this card’s thunder.
- High GPU boost clock
- Dual-slot form factor
- Great software included
- Loud fans
