Every new generation of GPU seems larger and more power-hungry than their predecessor. Is there any effort to produce faster GPUs that are smaller and use less power?
Every new GPU generation delivers more performance/W than the previous generation (mostly due to semiconductor process improvements) But the competition to have the fastest chip means that total power usage keeps growing.
Power efficient chips just doesn't generate headlines the same way.
But GPU power efficiency (gflops/watt) has been increasing at an exponential pace as well - over the last decades it has been consistent doubling every 2-3 years. So over 10 years we have had 10-30x improvements in power efficiency. The same is true for cost efficiency (gflops/dollar).
