Review: More affordable alternative to GTX 680 SLI/GTX 690

Phantom cooler has its own style. The fans are hidden and they can be seen only when looking straight at the card.

Three heatpipes are in charge of transferring the heat from the coolers base to the heatsink. Two 8cm fans take care of cooling the heatsink.

GTX 670 Phantom graphics card comes with two dual-link DVIs, standard HDMI and DisplayPort connectors. The card can run up to four displays simultaneously.

The cooler base is made of aluminum instead of more commonly used copper.

GTX 670 Phantom is about 24.7cm long, which is about the same as the reference GTX 670, but the Phantom cooler will take up three slots while the reference cooler is only two slots wide. This can prove to be a problem if you are planning on 3-way SLI.

Nvidia decided to use a minimalistic PCB, which is only 17.2cm long. Actually the cooler is to blame for the GTX 670's length of 24.7cm. As you can see from the pictures below, Phantom's PCB is slightly changed. All memory chips are placed on the GPU side, while with the reference design, odd and even memory chips were placed on opposite sides of the PCB.

Beside the difference in distribution of the memory chips, Gainward ’s PCB looks similar to the Nvidia’s reference PCB showed on picture below.

GTX 670 comes with 2GB of memory. It has eight memory chips, just like the reference card. Gainward’s GTX 670 Phantom runs Hynix memory chips (model No: H5GQ2H24AFR-R0C), which are specified to run at 1500MHz (6000MHz GDDR5 effectively).
