Design and Features

Now let’s take a closer look at the actual hardware.

Radeon HD 6670

We’ve got no surprises here. The low-profile form-factor ensures a lower manufacturing cost and also indicates that the graphics card is meant for a small multimedia computer in the first place.

The 61 watts of heat produced by the GPU at full load are supposed to be dissipated by a dual-slot cooler. The large heatsink guarantees that the Radeon DH 6670 won't easily overheat, but it makes the card bulkier and not easy to install into compact system enclosures.

The graphics card based on the junior Turks follows the same design concept. It may even seem identical to the Radeon HD 6670, but the placement of the power circuit components and some other features suggest that its PCB has not been simply borrowed from the senior cousin.

The cooling system of the Radeon HD 6570 is simple and does not go beyond the PCB’s dimensions. The heatsink is small and, considering the size of the fan and the GPU's power consumption (up to 50 watts), the graphics card may prove to be noisy.

Radeon HD 6450

The Caicos-based solution is slower and looks even more modest. It has fewer elements on its PCB than the Turks-based products. The small size and the low price of the Radeon HD 6450 make it ideal for a multimedia PC.

Unfortunately, this card is also equipped with an active cooling system which is the consequence of its increased power consumption compared to the Radeon HD 5450. The card's cooling system is almost the same as the one of the hotter Radeon HD 6570 and should cope with its job even in a poorly ventilated system case.
