ATI Radeon HD 4550 Budget DX10.1 GPU

We'd like to cover a few final data points before bringing this article to a close. Throughout all of our benchmarking and testing, we monitored how much power our test systems were consuming using a power meter. Our goal was to give you an idea as to how much power each configuration used while idling and under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, not just the power being drawn by the motherboards alone.

Total System Power Consumption
Tested at the Outlet



The Radeon HD 4550 proved to be quite power friendly.  The Radeon HD 4550 has the lowest idle and peak power consumption of all of the Radeons. A couple of the GeForce cards had lower idle power consumption, but only the GeForce 9500 GT 512MB DDR2 had lower peak consumption.

We normally talk about noise output in this section of of video cards articles as well, but because the Radeon HD 4550 we tested was passively cooled, it generated absolutely no noise.  In case you're wondering, heat wasn't a concern either.  Throughout all of our testing, the heatsink on the card got warm to the touch, but it was never hot enough to cause concern.

Marco's interest in computing and technology dates all the way back to his early childhood. Even before being exposed to the Commodore P.E.T. and later the Commodore 64 in the early ‘80s, he was interested in electricity and electronics, and he still has the modded AFX cars and shop-worn soldering irons to prove it. Once he got his hands on his own Commodore 64, however, computing became Marco's passion. Throughout his academic and professional lives, Marco has worked with virtually every major platform from the TRS-80 and Amiga, to today's high end, multi-core servers. Over the years, he has worked in many fields related to technology and computing, including system design, assembly and sales, professional quality assurance testing, and technical writing. In addition to being the Managing Editor here at HotHardware for close to 15 years, Marco is also a freelance writer whose work has been published in a number of PC and technology related print publications and he is a regular fixture on HotHardware’s own Two and a Half Geeks webcast. - Contact: marco(at)hothardware(dot)com
