Review: Acer Predator BiFrost Intel Arc A770 OC


The test configuration:

Lately, we have once again updated all our graphics using the latest drivers from NVIDIA, AMD and of course Intel. We also took the opportunity to slightly modify our test configuration. So here we go again for a new series of tests and therefore of graphics on this slightly modified configuration:

  • Motherboard: ROG Maximus Z690 APEX
  • Processor: Intel Alder Lake i9-12900K
  • Memory: 32 GB Corsair Vengeance 5200 CL38 DDR5
  • Graphics Card : Acer Predator BiFrost Intel Arc A770 OC
  • Cooling system : ROG Ryujin II 360
  • SSD : Western Digital Black SN750 2 TB + EKWB radiator
  • Power supply : Corsair AX1600i + 12VHPWR 600W adapter
  • Operating system: Windows 11 64 bits

For this test, we used a high-end configuration using an i9-12900K processor and DDR5. The use of a 144 Hz 4K display is also a prerequisite. For our tests we use a copy of the ROG PG27UQ.

Our test protocol:

All cards are tested at stock frequencies and without any optimization. For the various benchmarks, whether synthetic or gaming, we will opt for 1080p, 1440p and 2160p resolutions depending on the performance of the card. Here, with this mid-range model, we will only use 1080p and 1440p definitions.

As you can see, we have switched to Windows 11 and we have enabled the “ReSize BAR” in the BIOS, which is visible in GPU-Z. Now that you know everything about our test configuration, it’s time to start!
