No Flux Capacitor on GUNNIR Flux
Expreview had a chance to test Arc A770 GPU from GUNNIR.
GUNNIR Flux is a new series for just-released Intel’s Arc A7 desktop GPUs. The company introduced as many as four models in the series, featuring either black or blue color scheme. The card tested was the A770 in blue color scheme.
The FLUX GPU is a full custom design with dual 8-pin power connectors and 8+4 VRM phase design. It ships with a triple-fan and dual-slot cooling solution, which is sufficient even for some extra overclocking.
As said before, Intel has two A770 models, either with 16GB or 8GB. This model is based on the A770 SKU with 8GB VRAM. The FLUX card is factory-overclocked to 2400 MHz (default GPU clock is 2100 MHz), however, the memory clock is lower than on Limited Edition GPUs (17.5 Gbps). This card ships with 16 Gbps memory, just like the A750 series.
The card holds the non-reference 2400 MHz frequency very well. During 3DMark stress testing, the cooler has never surpassed 67°C while the clock was rock solid 2400 MHz throughout almost the entire test.
In terms of power consumption, the GPU had an average power consumption of 283.5W, which was measured with NVIDIA PCAT tool (in other words, it was accurate). The peak power consumption went as high as 329W though, which could be concerning. However, even more concerning is the idle power consumption of 48.7W. This issue has been mentioned by many reviewers of the Arc A7 Limited Edition GPUs, and this is something Intel has to fix soon.
Expreview says that they managed to overclock the A770 up to 3049 MHz, but this was not a stable configuration, and it did not work for long. The highest stable frequency was much lower at 2650 MHz, which is still 550 MHz above Intel specs. The editor confirms that with overclocking, the card’s performance improved by 6%.
Custom Intel Arc A7 GPUs are still very rare. In fact, not only they are hard to find, but barely any reviewer had access to a non-Intel model. To make matters worse, there are only 3 companies making such cards and each one is sold through a different retailer in a different country.
Hopefully though, we will see more design announcements and better availability, while Intel focuses on improving performance. And speaking of performance, if you are interested in how this card performs, check the review link below.
