GPU Frequency NVIDIA GeForce RTX 3090 FE Ti
We need to find out what the default GPU clock speed of the video card is. With both NVIDIA and AMD GPUs, the GPU frequency is dynamic. NVIDIA has GPU Boost, and AMD has its Game Clock and Boost Clock quoted frequencies. Typically, GPUs today can exceed the “Boost Clock” dynamically. We need to find out what it actually runs at, so we can compare the benefit of overclocking. To do this we will record the GPU clock frequency over time while playing a game. We use Cyberpunk 2077 for this with a very long manual run-through at “Ultra” settings recording GPU-Z sensor data.
In the graph, above the green bar represents the official GPU Boost clock on the GeForce RTX 3090 Ti Founders Edition which is 1860MHz. We can see from this graph that the GPU Boost clock speed while gaming is operating well above the official quoted GPU Boost clock. It starts off above 2GHz but then drops down to a very consistent and sustained 1995MHz, flat-lined.
First of all, this flat-line consistent performance is unique to see, because the GeForce RTX 3090 did not behave like that, it fluctuated more. However, on the GeForce RTX 3090 Ti Founders Edition it seems to be locked in pretty tightly. Also, at 1995MHz the video card is operating well above the GPU Boost of 1860MHz, it’s 135MHz higher or 7%. The GeForce RTX 3090 Founders Edition, for example, runs at around 1770MHz on average. Therefore, the GeForce RTX 3090 Ti Founders Edition is running about 225MHz or 13% higher GPU Clock. That’s a pretty decent clock speed increase.
GPU-Z Sensor Data
One thing that we did notice is that the GPU Voltage is running lower on the GeForce RTX 3090 Ti Founders Edition versus the GeForce RTX 3090 Founders Edition. On the GeForce RTX 3090 Ti Founders Edition GPU Voltage is at 1.0750V and on the GeForce RTX 3090 Founders Edition it is 1.0810V. Therefore, it seems NVIDIA was able to lower the voltage a bit, which will help with a reduction in temperatures.
