After DirectCU and Matrix series ASUS has a new GeForce GTX 780 card in its portfolio which even features a new revision of their DirectCU II cooler with 0dB Fan technology named STRIX, there is also a non-reference PCB which features a ten phase power design with super alloy components. Everything put together sounds like a higly compelling offer.

Today, we will be checking ASUS' newest STRIX Edition of the Geforce GTX 780 graphics card and show you all the strengths and weaknesses of this graphics card.

ASUS' GeForce GTX 780 STRIX OC Edition is based on NVIDIA's massive Kepler GK110 chip, which is manufactured by TSMC using the latest 28 nanometer process technology. With the GeForce GTX 780 you get twelve SMX units which results in 2'304 CUDA cores. Following the specs further, there are 192 TMUs, 48 ROPs, a 384 bit wide memory interface and 6GB of GDDR5 memory, which is clocked at 1'502 MHz (effective 6'008 MHz). In the end, there is a memory bandwidth of 288.4 Gigabyte per second. Concerning the GPU clock speed, it runs at a base clock of 889 MHz and a boost clock of 941 MHz. During our tests the highest boost clock we measured was 1'045 MHz and the average boost clock was also 1'045 MHz.

The ASUS GeForce GTX 780 STRIX OC Edition also supports GPU Boost 2.0. The first version of GPU Boost stopped overclocking the GPU when a certain power target was hit. This new second version of GPU Boost stops overclocking the card, when a certain temperature is being reached. This makes sense since the temperature is the bigger inhibitor than the power target in most cases. In this case the temperature target is 80 degrees Celsius. In other words, as long as the GPU runs at less than 80°C it will keep overclocking until the maximum frequency has been reached. This is why in our case the average boost clock was 104 MHz higher than the typical boost clock NVIDIA advertises.
