Intel Arc Revisit: 2023 driver update (Acer Predator BiFrost A770)

On this page we present some further benchmarks, directly comparing the Acer Predator BiFrost A770 16GB against Intel's A770 Limited Edition 16GB. For the Acer Predator card, we tested both the Default and Turbo profiles within the BiFrost software.

Power draw

There's a minimal difference, at best, in terms of power draw under load between the BiFrost and the Intel Limited Edition (LE). Even when using the Turbo mode, the BiFrost only drew 221.5W, so just 8 or-so Watts more than the LE. And when using the Default profile, power consumption was basically identical.

Clock speed

The small differences in power draw translate direct into clock speed. We saw no difference in average operating clock speed between the Intel LE and BiFrost when using the Default profile, as both hit 2400MHz. Using the Turbo mode did increase speeds fractionally, but only up to 2451MHz, so just a 2% difference.

Cyberpunk 2077

As expected, such trivial differences in clock speed means the real-world gaming performance of the two cards is functionally identical. We observed less than a single frame of difference comparing the LE to the BiFrost, even when using the Turbo mode, so there's no way you could tell the difference between the two cards while gaming.
