    The RADEON HD 5450 from Sapphire is based upon the ATI Cedar chip, the lowest end chip on the HD 5xxx series. The chip has 80 Stream Processors, which pales in comparison to the HD 5870 which has 1600 or the HD 5770 which has 800. The HD 5450 has 292 million transistors which also pales compared to the 2.15 Billion on the HD 5870 card.

    Most computer systems sold on the market today come with Microsoft’s Windows 7 Operating System. One of the new features of Windows 7 is the inclusion of DirectX 11. The DirectX API allows developers to use the graphics card for other purposes than games like Stream Processing via DirectCompute. One thing the HD 5450 does not have is Dual Precision Floating Point Operations. DP is not relevant as performance on this card is for the value market anyway.

    Every one of the Evergreen family of chips supports Eyefinity, allowing the connection of three or more monitors to the video card. AMD’s solution is much more elegant than NVIDIA’s solution which requires two video cards in SLI. The HD 5450 has this covered with a VGA port, a DisplayPort and a DVI-I port on the rear I/O allowing the attachment of three monitors to be done. You can also use a D-sub with an adapter but few computers use analog monitors these days.
