Today we analyse the third £200 R9 380X to hit our labs since launch – the Powercolor Radeon R9 380X ‘Myst Edition'. With so many driver updates in recent weeks, we went back to the drawing board and tested ALL the hardware today with the latest AMD and Nvidia drivers. We also finally managed to make the time to supplement our 1440p and 4K tests with results at 1080p. How does the Powercolor card fare against the competition?
As we said at launch – in today’s market there are surprisingly few current generation GPU options available at the £200 mark. Nvidia have had the GTX970 available for some time, but the prices for these cards are firmly in the £250 sector (HERE). Their less powerful GTX 960 is £100 less, available around £150 (HERE). AMD released their R9 380 earlier this year, and prices are competitive against the GTX960 (HERE). The R9 390 is AMD’s solution directly priced to compete against the GTX970 (HERE).

The R9 380X is quite similar in specification with the R9 380 – incorporating 32 ROPs, a 256 bit memory interface with core clocks and memory clocks both set to reference speeds of 970 mhz and 1425 mhz (5.7Gbps effective) respectively. There are however 128 texture units on the R9 380X, compared with the R9 380’s 112. The Stream Processor count has also been increased from 1792 to 2048.
The Powercolor Radeon R9 380X ‘Myst Edition' has enhanced clock speeds, and we will look at this in more detail on the next page of the review.
Maintaining our performance graphs has been a full time job in Q4 – Nvidia and AMD have been hard at work updating their drivers in recent weeks. In this review we test with AMD's Crimson 15.11.1 driver and the Nvidia 359.06 WHQL driver.
