The STRIX Gaming GTX 1080 8GB is ASUS' latest and greates single GPU graphics card, which comes with a factory OC, that pushes really hard on the new Pascal GP-104 chip. In combination with the vendor's DirectCU III cooler this might be silent yet very powerful solution for gamers wanting to push UHD at high levels of detail. We're certainly curious to find out what this beast can do.




Presentation




ASUS was amongst the first Nvidia add-in-card (AIC) partners that have decided to introduce a custom GTX 1080 graphics card which is using NVIDIAs latest and greatest GP104-400-A1 Pascal chip. For this graphics card, ASUS makes use of a custom PCB along side another updated version of their DirectCU cooler. On the backside of the card, there is a good looking backplate. A quick glance at the specs also reveals that this card ships factory overclocked.

Browsing the specifications of this card we find 2560 CUDA cores, 160 TMUs and 64 ROPs. For comparison reasons, the GTX 980 featured 2048 CUDA cores, 128 TMUs and 64 ROPs. This means that, compared to the same model from the previous generation, there are significantly more CUDA cores, TMUs and ROPs. Looking at clock speeds we find a base clock set to 1'784 MHz and the boost clock is at 1'936 MHz, whereas the NVIDIA reference cards runs at 1607MHz/1733MHz, therefore there is a very solid 11.7% factory overclock on the GPU.



As we already mentioned, ASUS decided to use a significant factory-overclock on their new GTX 1080 STRIX. While the reference GTX 1080 is set to work at 1607 MHz for the base clock and 1733 MHz for the GPU boost clock, the GTX 1080 STRIX runs at 1'784 MHz base clock and 1'936 MHz boost clock.

When it comes to memory clock speeds we see the memory running at default clock speeds which is 1251 MHz and effective 10008 MHz. Combine this with a 256 Bit memory interface and you end up with a total of 320 Gigabyte of memory bandwidth.

Whereas the typical boost clock is set at 1'936 MHz, the maximum boost of 2'050 MHz was achieved quite easily and the GTX 1080 STRIX held that clock most of the load time due to the capable DirectCU III cooler as well as good TDP target (nVidia's Boost technology being power-based and not temperature-based on this card). At this point we also ran Furmark to see how high the card overclocks, when the GPU is under maximum load. This way we can determine a worst case scenario regarding maximum boost clock. With this card we see clocks speeds of 1'860 MHz at 0.862v.
