Power Consumption

Cooling modern video cards is becoming more and more difficult, especially when users are asking for quiet cooling solutions. That's why the engineers are now paying much more attention to power consumption of new video card designs.

Test System
CPU:Intel Core 2 Duo E8400 @ 3.6 GHz
(Wolfdale, 6144 KB Cache)
Motherboard:Gigabyte P35C-DS3R
Intel P35
Memory:2x 1024MB A.DATA DDR2 1066+ CL4
Harddisk:WD Raptor 740ADFD 74 GB
Power Supply:OCZ GameXStream 700W
Software:Windows XP SP2


In order to characterize a video card's power consumption, the whole system's mains power draw was measured. This means that these numbers include CPU, Memory, HDD, Video card and PSU inefficiency.

The three result values are as following:
  • Idle: Windows sitting at the desktop (1024x768 32-bit) all windows closed, drivers installed.
  • Average: 3DMark03 Nature at 1280x1024, 6xAA, 16xAF. This results in the highest power consumption. Average of all readings (two per second) while the test was rendering (no title screen).
  • Peak: 3DMark03 Nature at 1280x1024, 6xAA, 16xAF. This results in the highest power consumption. Highest single reading
The HD 4670 lives at the lower end of the power usage spectrum. In idle it is one of the least demanding cards with a full system power consumption below 90W. Even when it is loaded the power consumption stays really low making it one of the most efficient cards on the market.
HIS has achieved great power consumption numbers with their card. It uses about 5% less power than the regular HD 4670 in all our testing scenarios.
