3DMark is an essential tool used by millions of gamers, hundreds of hardware review sites and many of the world’s leading manufacturers to measure PC gaming performance.
Futuremark say “Use it to test your PC’s limits and measure the impact of overclocking and tweaking your system. Search our massive results database and see how your PC compares or just admire the graphics and wonder why all PC games don’t look this good.
We are beginning to see a pattern now – at the out of the box speeds, the R9 390 delivers solid, if unremarkable results. After manually overclocking however, the performance level exceeds the reference clocked GTX980 and R9 390X solutions.
At Ultra HD 4K resolution, the PowerColor Radeon R9 390 PCS+ is around 200 points behind the R9 390X. When overclocked to the limit it manages to slightly outperform the reference clocked R9 390X.
