1 Blu-ray drive and HD capable monitor required.
2 Requires a 10-bit display
3 The ATI Radeon™ HD 4550 delivers 96 GigaFLOPS compared with the ATI Radeon HD 3450 which delivers 48 GigaFLOPS.
4 ATI CrossFireX™ technology requires an ATI CrossFireX Ready motherboard and may require a specialized power supply.
5 The ATI Radeon HD 4550 GPUs can upscale video display to 2560x1600 on dual-link monitors which is almost twice the display resolution of 1080p displays.
6 Over a one year period the ATI Radeon™ HD 4550 consumes 113.88 watts of energy in comparison with the ATI Radeon HD 3650 D2 which consumes 283.24 watts of energy based on the following calculations:
ATI Radeon HD 4550: 73 watts per year (8 hours a day at maximum power) + 40.88 watts per year (16 hours a day at idle)
ATI Radeon HD 3650: 195.64 watts per year (8 hours a day at maximum power) + 87.6 watts per year (16 hours a day at idle)
This results in an expected energy savings of 169.36 watts for the ATI Radeon HD 4550. This may differ paces on the amount of time your computer is on and the percentage of time it is under full load.
7 The ATI Radeon HD 4350 GPUs are capable of outputting DisplayPort signals. Manufacturers of ATI Radeon HD 4350 graphics cards may choose to implement this functionality – you may inquire of them which models, if any, support DisplayPort.
8 ATI PowerPlay™ technology consists of numerous power saving features. Not all features may be available in all ATI Radeon HD 4550 graphics card.

The product descriptions, features and performance results are for graphics cards based on AMD´s standard reference design for the ATI Radeon™ HD 4550 with DDR3 memory, 800MHz memory speed and 600MHz engine speed. Third party manufacturers may modify these reference designs, which can result in product specifications, features and/or performance results different from those described in this document. Buyers should confirm exact specifications, features and performance of third party graphics cards before purchase.

ATI PowerPlay™, ATI Avivo HD and ATI Stream™ are technology platforms that include a broad set of capabilities offered by certain ATI Radeon GPUs. Not all products have all features and full enablement of some capabilities may require complementary products.

ATI Radeon™ HD graphics chips have numerous features integrated into the processor itself (e.g., HDCP, HDMI, etc.). Third parties manufacturing products based on, or incorporating ATI Radeon HD graphics chips, may choose to enable some or all of these features. If a particular feature is important to you, please inquire of the manufacturer if a particular product supports this feature. In addition, some features or technologies may require you to purchase additional components in order to make full use of them (e.g. a Blu-Ray or HD-DVD drive, HDCP-ready monitor, etc.).
