AMD’s ATI Radeon HD 4550 Video Card Review

The Test System

The ATI test system was running Windows Vista Ultimate 64-bit with SP1 and all available Microsoft updates. The ATI Radeon HD 4870 X2 was using CCC 8.8 beta drivers. The ATI Radeon HD 4670 and Radeon HD 4550 were using 8.9 drivers. All results shown in the charts are averages of at least three runs from each game or application used.

The Video Cards:

• ATI Radeon HD 4870 X2 – GDDR5(500MHz/1800MHz)
• PNY GeForce GTX 280 – GDDR3 (602MHz/2214MHz)
• BFG Tech GeForce GTX 260 – GDDR3 (602MHz/2214MHz)
• ATI Radeon HD 4670 – 512MB GDDR3 (750MHz/2000MHz)
• XFX GeForce 9600 GT – 512MB GDDR3 (650MHz/1800MHz)
• EVGA GeForce 9600 GSO – 384MB GDDR3 (550MHz/1600MHz)
• NVIDIA GeForce 9500 GT – 256MB GDDR3 (600MHz/1000MHz)
• ATI Radeon HD 4550 – 512MB GDDR3 (600MHz/1600MHz)

All of the ATI video cards were tested on our Intel X48 Express Test platform, which is loaded with the latest and greatest hardware. The Intel Core 2 Quad QX9770 ‘Yorkfield’ processor was used for testing as it proves to be the best desktop processor when it comes to game performance. The test system was also loaded with 4GB of memory and water cooled to ensure throttling of the processor or memory wouldn’t cause any issues. The Corsair DDR3 1600MHz memory kit was run at 1600MHz with 9-9-9-24 memory timings. The Gigabyte X48T-DQ6 motherboard was running BIOS version F5, which was the most recent available at the time. It should be noted that the Radeon HD 4870 X2 was run on the Coolermaster 1000W power supply when running in CrossFireX mode as the Corsair HX 620W power supply was unable to handle the load. The Corsair HX 620W power supply would run the cards and was pulling more than 791W from the wall, but the games displayed artifacts and the +12V rail was low. A quick switch to a bigger PSU, and the issue was resolved.
