If you own an AMD Radeon graphics card based on “Fiji”, “Hawaii”, or “Tonga” architectures, you can now unlock all the disabled compute units using a software tool.
The software tool in question is CUINFO, developed by tx12, a member of Overclock.net forums. The software tool itself won’t unlock all the disabled stream processors though, it can only detect the number of stream processors that have been disabled in your AMD Radeon graphics processor. You can then enable those disabled stream processors with the help of a custom BIOS.
As you can see in the benchmark below, enabling some of the disabled stream processors does bring a decent improvement in performance, all without having to overclock your graphics card in any way.
