Si bien la Nvidia GeForce GTX 780 Ti no puede hacer frente en términos de rendimiento/precio a la AMD Radeon R9 290X, si lo hará en términos de temperaturas y overclocking, ya que los chicos de Chiphell cuentan con una muestra de la Nvidia GeForce GTX 780 Ti para su análisis, la cual fue overclockeada de unos iniciales 928 MHz en modo Boost/Turbo hasta alcanzar los 1019 MHz para luego ser probada a fondo mediante el software FurMark desvelando que después de 11 minutos, la gráfica mantenía su temperatura en 82 grados, lejos de los 95 grados que podemos encontrar en la Radeon R9 290X con frecuencias de referencia.
Si nos dejamos de pruebas de estrés (es prácticamente imposible que en un uso normal la gráfica reciba tanta carga), con overclock estable a 1054 MHz la gráfica se mueve en unas temperaturas en torno a los 79 grados bajo en los test de benchmarking 3DMark 11, distanciándose aún más de las temperaturas de su directo rival, y todo ello, aparentemente sin aumentar su consumo energético, indicando que el límite del overclock de la GPU GK110 de la GTX 780 Ti podría estar en los 1100-1200 MHz sin problemas, aunque el rendimiento no aumenta considerablemente, pero al no haber un mayor consumo, ni un aumento de las temperaturas, cualquier potencia adicional es bien recibida.
Fur Mark
Let me start with his Fur Mark test, this is probably the most interesting part. Card running at 1019 MHz, which is higher than reference 928 MHz boost, card could sustain a temperature of 82 C. That’s after 11 minutes, so I guess this is a really good result. Although he was testing his card on testing platform, so the heat dissipation from other components didn’t affect the GPU temperature that much.
3DMark scores
GeForce GTX 780 Ti can offer a very similar performance to both GTX TITAN and R9 290X, but the leaker claims that in newer 3Dmarks Radeon can still offer better scores. The thing to notice is again the temperature with an average at 79 C.
Card was stable only up to 1054 MHz, rising a clock to 1092 MHz didn’t increase the performance, instead GPU Boost 2.0 made the card run slower due to temperature limitation. I’m not sure why his sample has such a bad overclocking potential. Apparently he didn’t increase the power limit. According to my knowledge some GTX 780 Ti samples can reach 1100-1200 MHz without any problem. Anyway, here are the results.
