We already know the R9 390 is a powerful card priced at a reasonable amount of money. In my opinion the R9 390 is the jewel in AMD's lineup – at £269.99 inc vat you can overclock this solution to perform better than the more expensive R9 390X.
We used the latest version of MSI Afterburner to overclock today.
We managed to push the core to 1,133mhz, around 9% faster than the preoverclocked ‘out of the box' settings. The GDDR5 memory could be enhanced to 1,637mhz before artifacting would occur (6.5Gbps effective).
All our graphs today highlight, performance from the Sapphire R9 390 Nitro at ‘out of the box' speeds, along with a yellow arrow pointing upwards to indicate results at 1,133mhz/1637mhz. This will show what you can expect out of the R9 390 architecture before it reaches a limit. Obviously not all cards will overclock to the same level, but this is a good indicator. We also want to see how a manually overclocked R9 390 will compare against a reference R9 390X.
