I will just guess but I suspect he doesn't mean electricity or wattage...

The Radeon 5450 is not a powerful card... integrated cards (Intel HD 3000 for e.g.) are outperforming it now.

AMD is also re-badging their cards now like Nvidia so it's easy to be a bit disappointed (putting it mildly) in video cards nowadays (both Nvidia and ATI/AMD are doing this).
