As expected, the overclocked N780 Lightning card emerged victorious, and we managed to overclocked its GPU by 17% to 1148MHz, while its video memory was overclocked to 6452MHz, which was a 7% increment. This can be attributed to the card's superior digital power management system; while our overclocking efforts improved the Lightning's performance by 12- to 12.6%! To recap, the card boasts of a 20-phase power design; hence, its overclocked GPU and video memory buffer were able to perform reliably. In comparison with its strongest competitor of the lot, the ASUS GeForce GTX 780 DirectCU II OC, the winning N780 Lightning card managed to outpace it by approximately 6% on both occasions.
The custom cooling system of triple fans performed well to keep the N780 Lightning operating at 53 degrees Celsius. This was the second lowest temperature recorded of the cards under load. Coincidentally, the N780 Lightning card also registered the same operating temperature as its counterpart, the MSI GeForce GTX 780 Twin Frozr VI Gaming OC.
Its idle power draw of 149W made the MSI N780 Lightning card just second to the ASUS GeForce GTX 780 card that has the highest idle power draw of 156W. Under load, the N780 Lightning card drew the most power at 440W! Its power consumption profile is rather close to that of the GTX Titan.
