GTX 970 vs GTX 980 Ti Cuda Performance

[mahmutsoylu]

Hi

I have two pc;

1 - Core i7 6700k - 16 GB Ram - Nvidia GTX 980 ti (2816 Cuda Cores)
2 - Core i7 4790k - 8 GB Ram - GTX 970 (1664 Cuda Cores)

I can try convert 75 min HD TV record files;

980 Ti: Encoding FPS:440.58 Time: 00:04:15
970: Enconding FPS:519 Time:00:03:35

Why gtx 970 faster 980 Ti?

Hi mahmutsoylu
My guess is that the 970 is bundled with the Intel HD Graphics 4600 and the 980 is bundled with the Intel HD Graphics 530 only way to tell is compare apples to apples.

Is only about a 15% difference, it could vary that much based on differences in bus speeds and mobo architecture between 2 machines. Source read speed could be slightly different as well.

Hi,

My
1. PC Gigabyte z170x gaming 7 motherboard, Corsair 2133 mhz DDR4 ram, Samsung 950 pro m.2 SSD (2500mb read/1500mb write) and 980 Ti
2. PC Gigabyte z97x d3h motherboard, Corsair 1666 mhz DD3 ram, Kingston V300 240 GB SSD (450mb read/450mb write) and 970

1. The computer must run faster

I get almost exactly a 15% faster encode from a SATAIII internal HDD than a USB 2.0 external HDD with my GTX 980 on the same system. The speed of the source drive is a factor.

Have you tried using Quick Sync? Both your CPU's have it...
