Full 3D performance mode: varies - worst case TDP 182W for GTX 260.Full 3D performance mode: varies - worst case TDP 236W for GTX 280.Let's take an overview on what we just said:
#Nvidia model p280 driver download movie
Another nice example is that movie playback is accelerated and enhanced over the GPU (Purevideo), when you decode 1080P content (Blu-ray) movies you'd figure that it would use up a lot of power, right ? Think again. Remember what I said about the GPU being able to shutdown segments of the GPU? Likely (and I'm not 100% sure here) mainly the video processor, IO and perhaps one shader block for some post-processing are at work. While decoding a 1080P movie over the GPU this product utilizes only 35 Watts. I think the previous generation products consumed up-to 70 watts alone in idle. in idle this 1.4 Billion transistor encounting graphics processor only consumes 25 watts. Once we fire of a 3D application at it it'll jump up towards it's designated clocks, and the same thing happens for the memory.įor example.

But more interestingly, have a look at the shader domain, it's clocked down towards 100 MHz if not used. I've been trying to figure out a way to actually show these dynamic processes and I can actually show you a little tip of that iceberg.Ībove in the screenshot you can for example see the core domain hop from 400 towards 600 MHz when needed. In GPU terminology this is called clock-gating circuitry, it effectively "shuts down" blocks of the GPU which are not being used at a particular time, reducing power during periods of non-peak GPU utilization. Very interesting is that certain parts of the GPU when not used, can be shut down, preserving energy. NVIDIA's integrated these 'p-states' and allows the GPU to alter clocks, voltages and frequencies on the fly. What this means is that depending on the task at hand you assign to the GPU, it'll react to that in terms of power consumption. NVIDIA made sure several new power states are active in the GPU. The new GPU however is one of the most energy aware products you'll find on the market today. well you figured that out yourself already I guess. More transistors means more power consumption.

Since we just briefly touched the topic of power consumption, for a product of this caliber it's really not that bad.
