Review: Acer Predator BiFrost Intel Arc A770 OC


Temperature, consumption and nuisance:


In order to measure the temperatures, we opted for the Superposition stress test in Extreme mode. We opted for three 5 minutes runs with 10 minutes interval between each test. We took advantage of this benchmark in order to measure the power consumption of the graphics card for the table above.

In order to know the temperature in Idle, after having finished the three loops of the stress test, we let the card rest for 20 minutes before reading the temperature. It should be taken into account that most of the cards have the “0 dBa” technology and therefore, the fans turn off below a certain temperature, often between 50 and 55°C. This means that it takes longer to dissipate the heat after a period of stress testing or gaming. A card without this technology will be noisier than the others at rest. Small reminder: our temperature readings are taken in Open-Air. In a closed case, the cards will necessarily be hotter.

Our Predator BiFrost Intel ARC A770 OC is placed at the bottom of the graphic, which is not a very good thing in itself, but… the ventilation curve seems to us to be very well defined since the card is very quiet. We were afraid of the noise of the blower fan but no worries on that side.

Power consumption (whole configuration) :

We use a power meter by reading the power consumption on the outlet of our power supply. Our modular power supply is a CORSAIR AX1600i. The result we propose is the average of the total consumption of our configuration. Only the graphics card changes between each reading. It is therefore easy to calculate the difference between each graphics card.

Surprise but not really in a good way since the power consumption is above all its direct competitors. Even if we would have preferred a better energy consumption, we are on a first generation and we will be a little more indulgent with Intel.
