Notes
We're comparing the ASUS Radeon HD 5770 Voltage Tweak directly against a stock-clocked Sapphire Radeon HD 5770 and XFX GeForce GTX 260 - both of which are priced at around the same level. To see how the Juniper GPU compares against a bevy of competitors, please head here.Comparing it against just the basic HD 5770 will show how great a performance improvement is realised by increasing clocks, and looking at GTX 260's numbers will provide a means of evaluating how it fits into the bigger picture.
Overclocking the ASUS card with the default voltage results in a stable speed of 950MHz core and 5,680MHz memory, up from 850MHz/4,800MHz - a not-too-shabby increase.
Dialling up the engine voltage from the shipping 1.125V to 1.287V - a 14.4 per cent increase - boosts the engine clock to a stable 1,003MHz. The memory speed remains the same, though.
Based on a sample of just one, there does appear to be merit in adding extra voltage to the core. We're also including numbers for the over-volted card's power-draw and temps, and they make for some very interesting reading.
