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.

se escono queste progressivamente non verranno più vendute
comunque si tratta ancora di indiscrezioni ma ati deve rinnovare la fascia media soprattutto tra la 3870 e la 3870 x2 c'è un buco, magari aggiustano i prezzi
