GIGABYTE GTX 670 OC WindForce 3X 2GB Review

Overclocking and Temperatures

The GIGABYTE GTX 670 OC WindForce 3X 2GB comes factory overclocked at 980MHz (boost to 1059MHz) from 915MHz (boost to 980MHz), a modest 7% increase. Memory clock frequencies were untouched at 1502MHz.

By setting the fan speeds to 100% (which gives a reassuring whoosh and not the ruckus of a leafblower), we could further bump the core clocks to 1134 MHz (boost to 1213MHz), which is an impressive 15% increase. Note that your actual mileage may vary due to the ASIC quality "lottery".


The new version of Furmark (1.10.0) is very punishing to new generation GTX6XX/R7XXX cards, forcing them to perform at full potential and output maximal heat. In this case we got a load temperature of 68 degrees celsius (ambient about 22 degrees), which shows that the WindForce triple fan cooler performs as advertised and actual gaming workloads should be around 10-15 degrees lower. The effective core operating frequency also flat-lined at 1330MHz, which was the case during our benchmarks.


Test Setup


CPU: Intel Core i7-3960X @ 4817MHz 1.52v
Motherboard: ASUS Rampage IV Extreme (Bios 0018)
Memory: G.Skills ARES 2133MHz DDR3 16GB Kit
Power Supply: Antec True Quattro Pro 1200W
Storage: Intel 520 series 240GB SSD
Graphics Cards / Drivers:


GIGABYTE GTX 670 OC WindForce 3X 2GB




GIGABYTE GTX 680 OC WindForce 3X 2GB


300.99 drivers:

NVIDIA Reference GTX680


296.10 WHQL drivers:

ASUS GTX580 DirectCU II 1.5GB


8.960 beta drivers:

MSI R7970 Lightning 3GB

AMD Reference Radeon HD 7970 3GB

Sapphire Radeon HD 7950 OC Edition

AMD Reference Radeon HD 7870 2GB

ASUS HD6970 DirectCU II 2GB


To prevent GPU Boost (NVIDIA's adaptive throttling mechanism to cheat in benchmarks) from interfering with the clocks, we need to change this setting in the Nvidia Control Panel.
