Design and Functionality

There’s nothing extraordinary about the appearance of the new card from EVGA as it looks similar to the reference GeForce GTX 670.

Besides some external differences such as the back-plate, the card features an originally shaped vent grid in its mounting bracket. It helps exhaust the hot air from the cooler.

 

Take note that the vent grid is as large as possible. There are even vent slits above the DVI connectors. The video outputs, including dual-link DVI-I and DVI-D, HDMI and DisplayPorts, are neatly covered with rubber caps.

There are two MIO connectors (for building 2-, 3- and 4-way SLI configurations) and two 6-pin power connectors in their conventional locations on the PCB.

 

The GeForce GTX 670 is specified to have a peak power draw of 170 watts and is recommended to be used with a 500-watt power supply.

Contrary to our expectations (the card has 4 GB of memory after all!), after we removed the cooler we saw an exact copy of the reference GeForce GTX 670 PCB with a tall aluminum heatsink on the power circuit components.

The single difference is the double amount of memory chips which are located on both sides of the PCB.

Despite that, the 4+2-phase power system (GPU+memory) is identical to the reference card’s. The 28nm GK104 chip was manufactured in Taiwan on the 15th week of 2012 (mid-April) and is revision A2 (the only revision employed on serially produced cards so far).

It is clocked at 967 MHz in 3D mode (boosted to 1046 MHz), which is 5.7% above the reference card’s GPU clock rate. This factory overclocking is hardly impressive. Every card in our review of three unique GeForce GTX 670s was faster by default. The clock rate is dropped to 324 MHz in 2D mode. We were lucky to get a GPU with 100% quality score, according to the latest GPU-Z:

This suggests some high overclocking potential.

The card’s 4 gigabytes of onboard memory are represented by FCBGA-packaged chips from Hynix Semiconductor which are installed on both sides of the PCB.

The chips are labeled H5GQ2H24AFR R0C, just like on the reference GeForce GTX 670, and have the same clock rate of 6008 MHz. They are connected via a 256-bit bus.

Here’s a summary of the EVGA GeForce GTX 670 Superclocked specs as reported by GPU-Z:
