Ultra durable VGA board provides dramatic cooling effect on lowering both GPU and memory temperature by doubling the copper inner layer of PCB. Gigabyte ultra durable VGA can lower GPU temperature by 5% to 10%.Ultra durable VGA board reduces voltage ripples in normal and transient state, thus effectively lowers noises and ensures higher overclocking capability. Gigabyte ultra durable VGA graphic accelerators improve overclocking capability by 10% to 30%.Ultra durable VGA board allows more bandwidth for electron passage and reduces circuit impedance. The less circuit impedance, the more stable flow of current and can effectively improve power efficiency. Gigabyte ultra durable VGA can lower power switching loss by 10% to 30%.
