Asus GTX 670 DirectCUII - Review

We put this card to the test

In this review we are going to be putting the Asus GTX 670 DCII Graphics card through its paces. The GTX 670 is the smaller brother of the GTX 680 and while the cards have recently been superseded by the 700 series, the 670 is still a beast of a card and one we thought we should test.

The GTX 670 uses Kepler 28nm GK104 architecture which is used in both the GTX 680 and GTX 690, it features Nvidia’s GPU Boost technology which allows adaptive overclocking of the card so when the card can it will run even faster, It also benefits from Nvidia Surround technology which allows you to have up to four monitors running from one card whilst also coming complete with Nvidia Adaptive V-Sync , the card also features cornerstone technology from Nvidia such as 3d Vision and PhysX so you won’t miss out.



Now let’s get onto the key features of this card, the Asus GTX 670 DCII features some slight differences to the normal GTX 670. The main as you can see in the images is the dual fan cooler which is a vast improvement over the stock Nvidia cooler in both noise and cooling ability, being aided by being in direct contact with the graphic cards GPU (Graphics Processing Unit) rather than being connected to a baseplate which then makes contact with the GPU, this means that this card does weigh more than a stock card.

The Asus card uses the same clock settings as a standard GTX 670, featuring a base clock of 915 MHz and a boost clock of 980 MHz, the Memory Clock is 1.5Ghz GDDR5 (6GHz effectively) through a 256-bit memory bus these spec  allow the card to have a total memory bandwidth of 192.2GB/s and a Bilinear Texture fill rate of 102.5 Giga Texel’s/sec  which isn’t too shabby.

Additionally the card feature DIGI+ VRM with 8-Phase Super Alloy Power, which from their website indicates that the components coated by this technology should benefit from a 15% performance boost 2.5 times longer lifespan and a 35°C cooler operation. (see the below image for a breakdown)

What’s On/In The Box?

The Card itself was supplied in a large box, which proudly boasts some of the features outlined above, it gives a few more of the ins and outs of the features as well, on the side of the box it lists the recommended system requirements which are 2x6pin power connectors and at least a 500W PSU with 38 Amps on the 12V rail.


Inside this main box is…another box, the internal box is designed more like a presentation box featuring an embossed gold Asus logo and a smart corrugated feel, opening further we find…another box this one contains the accessories such as driver discs, user manual as well as a dual Molex to 6pin power converter, but behind all of this and a rather large layer of foam we finally get to the card itself.

To the Card

The graphics card itself looks very nice, with the prominent Direct CU cooler shining through the fan blades; it’s hard to grasp the size of the cooler until you place it into your system, this card from Asus is almost an inch bigger in both height and length compared to a standard GTX670 and all of the extra space is put to use expertly, the cooler uses two 80mm fans to cool the DirectCU II unit with four large heat pipes to channel the heat to the radiator fins, whilst staying quiet overall.
