Intel Arc A770 “Alchemist” GPU Overclocked Beyond A Record-Breaking 3.5 GHz

wccftech.com:

Intel's top Alchemist GPU, the Arc A770, has been overclocked to a record-breaking 3.5 GHz clock frequency, making it the fastest on the planet.

The record comes from overclocker and enthusiast, Skatterbencher who utilized LN2 cooling & the ElmorLabs EVC2. Skatterbencher already has a detailed guide that explains how to overclock Intel's Arc GPUs including the Arc A770 and how some limitations can be bypassed.

For the overclocking session, an Intel Arc A770 Limited Edition GPU was used which was mounted to the PCIe slot through a 90-degree riser, and a dual-layer tape was plastered around the GPU to make sure that the ACM-G10 "Alchemist" die was protected from the weight of the CPU container that was used to hold the LN2 since the standard GPU LN2 container wasn't compatible with the mounting layout of the card. It is told that there are five major limitations that hinder overclocking of Alchemist chips which include:

The process to bypass and manually tune each of these settings is explained here. In the end, the card was pushed all the way up to 3586 MHz with a voltage of 1.305V and a temperature of -50C. It was only good enough for a couple of seconds but the GPU would eventually crash. A frequency of 3400 MHz (1.285V) was good enough for light workloads while 3100 MHz allowed for some runs in 3DMark Test. Skatterbencher settled for 3012 MHz at 1.12V with -30C temperatures as that allowed for stable performance within all 3DMark benchmarks except one (3DMark Fire Strike).

The resultant scores for the Intel Arc A770 Alchemist GPU are very impressive with up to 26% gain in 3DMark Time Spy. In 3DMark Speedway Stree Test, the Intel Arc A770 GPU was able to achieve 3 GHz with 1.114V & total GPU power draw peaked out at 258W.
