NVIDIA GeForce GTX 1080 Ti Video Card Review

NVIDIA is launching the fastest video card it offers for gaming today in the new $699 GeForce GTX 1080 Ti. We will take this video card and test it against the GeForce GTX 1080 and GeForce GTX TITAN X at 1440p and 4K resolutions to find out how it compares. Is it really faster than a $1200 GeForce GTX TITAN X Pascal?


NVIDIA GeForce GTX 1080 Ti - GPU Clock

On this page we are going to look at the GPU clock consistency while gaming. That is, we will game and record the GPU Clock speed real-time and find out if the GPU can maintain its specified clock speeds. We will be using a multiplayer game of Battlefield 1 for an extended time at 4K.

The default base clock on the 1080 Ti is 1480MHz, so we will put our red line at that mark on the graphs below. We do not want to see the clock speed drop below this frequency. The GPU boost clock is 1582MHz, so we expect to see the clock speed at or above this frequency while gaming.

From this graph you can see that the actual real-time clock speed while gaming is well above the boost clock of 1582MHz for the entire gaming session. It starts off high at 1886MHz, but quickly drops within minutes to its average clock speed as the video card's cooling system becomes heat-soaked. It only dropped to 1721MHz which is still way above the boost clock. The average clock speed was 1781MHz. The fact that it never drops below 1700MHz is excellent. We will consider this a good starting point for our overclocking tests later on.

The GPU hit a maximum temperature of 84c while gaming and averaged 80c. The video card's BIOS is set to cap the temperature at 84c. Even at 84c the video card still maintains those frequencies above 1700MHz while gaming, so even if you consider this temperature warm it isn’t throttling the frequency at all.
