Review: Acer Predator BiFrost Intel Arc A770 OC



At the time of the release of Intel graphics cards, overclocking was far from obvious with crashes when we touched the different parameters. So when is it with its new drivers and can we finally enjoy a gain?

Step 1: benchmark scores

Of course, it is important to already know the scores we obtained on the Time Spy benchmark as well as on the maximum boost frequency reached. This will allow us to have a reference score and thus be able to judge the gains in overclocking . We obtain a global score of 14777 points under Time Spy and more exactly 14427 points if we isolate only the one obtained by the GPU. The maximum frequency for the Boost is indeed 2400 MHz.

Step 2: the two other modes within the software

As we have shown you, the ” Predator BiFrost ” software has a silent profile and a Turbo profile (0C). We will activate them in turn to see what impact they have.

Let’s start with the silent mode which gives us an overall score of 13947 points and 13513 points for the GPU score. The card sees its Boost frequency decrease to 2250 MHz and therefore a lower temperature too since we go from 73°C to 66°C. The card is already silent by default and we did not really notice any difference with the silent mode.

The Turbo mode did not bring us anything in terms of performance since the Boost frequency remains blocked at 2400 MHz and is therefore perfectly identical to the default mode.

Step 3: Manual overclocking

To do this, we went back to the Intel drivers and the software that allows you to set up and monitor your graphics card. We were able to push the Boost frequency to 2580 MHz while keeping the fan in automatic mode. Unfortunately, there is still no way to change the memory frequency.

We were thus able to obtain an overall score of 15440 points and 15141 if we isolate the GPU score. It’s a very good thing that overclocking is easier than at launch, hoping to see the memory frequency unlocked in the coming weeks.
