Intel positions its Arc A770 desktop graphics card as a midrange board for gaming. Many midrange graphics cards come factory-overclocked, but applying extreme overclocking to such GPUs isn't too common — you won't set a new overall performance record. But SkatterBencher decided to set a record for the fastest Intel Arc GPU and gave his Acer Predator BiFrost A770 the liquid nitrogen treatment, achieving impressive results.
SkatterBencher succeeded in pushing the Intel Alchemist GPU to 3586 MHz, up from the default 2400 MHz boost clock. Of course, the graphics processor became highly unstable at this level and the overclocker could only maintain this frequency for a few seconds before the screen froze, necessitating a system reboot. During this process, the temperature of the liquid nitrogen container was -80°C, while the GPU's temperature hovered around -50°C.
The overclocking results varied greatly depending on the type of workload as well.
- Light Workload: The GPU was able to reach a peak frequency of 3400 MHz at 1.285V. The GPU temperature was approximately -30°C.
- 3DMark Benchmark: During a 3DMark benchmark, the GPU could hit a maximum frequency of 3100 MHz. However, ScatterBencher was unable to complete more than one Time Spy game test at this speed.
- Complete 3DMark run: The GPU was able to run at 3012 MHz at 1.12V to complete a full 3DMark benchmark run. This frequency was necessary to achieve the top position in the 3DMark Night Raid benchmark among the A770 boards.
