The Tech Report points out that NVIDIA's HybridPower technology is as good as dead on the desktop PC. NVIDIA claims the latest high-end GeForce cards don't support HybridPower because they already have significantly lower idle power consumption:
Unfortunately, it seems that HybridPower has no future on the desktop. The new GeForce GTX 285 and 295 don't support it, for example, and neither will the new desktop GPUs that Nvidia has in the pipeline. According to Senior Technical Marketing Manager Sean Cleveland, HybridPower has been dropped from desktop parts because, thanks to the improved idle power consumption of Nvidia's latest graphics parts, it no longer "substantially improves the user's experience." HybridPower will live on in Nvidia's mobile platforms, where the company still sees merit in the technology's ability to reduce heat output and prolong battery life.
