Overclocking, Power Consumption
By overclocking the Radeon R9 270X and Radeon R7 260X we wanted to see if they could be pushed further than the Radeon HD 7870 and HD 7790, respectively. Short answer is, they cannot.
The R9 270X core was boosted by 14% to 1.2GHz while the memory was pushed just 2.1% higher to 5720MHz. The Radeon R9 270X also made a core frequency of 1.2GHz which was a 9% increase and the memory also overclocked by 2.1% to 6640MHz.
As you can see the performance gains from our overclock were slim at best as we saw just 1-2 fps more in most cases.
Unsurprisingly the Radeon R9 270X and Radeon HD 7870 consumed virtually the same amount of power under load. This was also the case with the Radeon R7 260X and Radeon HD 7790.
