3DMark Vantage
These are very interesting results: in our 3DMark Vantage test the Radeon HD 5830 performs MUCH closer to the HD 5850 than to the HD 5770 – a result that wasn’t really seen in any of our gaming tests.
This card should do a fine
This card should do a fine job of representing the 5830’s performance, but noise levels, GPU temperatures, and even power consumption may vary on the actual products. That hasn’t stopped AMD from offering power consumption estimates of 125W at peak and 25W when idle, though.
