The Radeon HD 6670 and HD 6570 Reference Cards
As is normally the case, budget graphics cards aren’t much to look at as they tend to be as cost effective as possible. That trend continues with the likes of AMD’s Radeon HD 6670 and HD 6570 options.
First up is the Radeon HD 6670 1GB GDDR5 card that actually has a larger cooler than you might have expected. Keep in mind that these are AMD built reference cards and you will likely NOT find identical units for sale in the market. I would fully expect to see options from XFX, Sapphire and others that will fit into a single slot configuration even though this one does not.
The back of card is pretty unassuming and is devoid of any of the memory chips responsible for its 1GB frame buffer.
One of the key benefits to these new Turks-based cards is the lack of any kind of PCI Express power connection requirement. At fewer than 75 watts, the HD 6670 is able to draw everything it needs from the PCIe bus directly.
The external connections configuration on this reference model includes a dual-link DVI output, analog VGA and a full-size DisplayPort connection. Even though the HD 6670 CAN support four displays, this particular configuration won’t.
Here we see the Radeon HD 6570 – notice the "ATI" logo on the cooler – oops, I guess someone used some left over plastic…oh well. The PCB is very similar though with a slightly cooler GPU they were able to make reference cards with a single slot cooling design.
Again, nothing much to see here on the back of the card.
The display output configuration is also the same. Again, with these only being reference cards, don’t put too much stock into this.
The back of the card does not have any kind of power connection….I fee like I am repeating myself here but if I don’t show you SOMEONE is going to ask.
Removing the heatsinks from the card reveals the bare PCB and the Turks GPU of 716M transistors.
Next to our classic American quarter, the Turks die is tiny and with 480 stream processors doesn’t have any spare room…
And just for a comparison, this is the die of Caicos, the Radeon HD 6450 that we are going to be reviewing at a later time. This GPU is only 370M transistors.
