Intel seems to have designed graphics cards Arc A770 perfectly capable of undergoing a significant rise in frequency.
While presenting the A770 Limited Edition card in detail, Tom Petersen and Ryan Shrout returned to the overclocking potential of the two main cards in the range, the A770 therefore, but also the A750.
Exceed base frequency… automatically
Through their presentation, the two Intel employees first explained how the Arc range works, namely that in a classic way, the GPU varies its frequency according to the load.
Basically, the Arc A750 is thus clocked at 2050 MHz when the Arc A770 goes a little further, at 2100 MHz. In the video example, the friends used the game Hitman 3which demanded a bit more power from the GPUs, especially the Arc A750.
Thus, we can observe that the GPU then goes significantly further than the base frequency and, on the Arc A750, we are now talking about a frequency of 2,400 MHz that ” everyone should be able to reach without having to do anything.
Up to 2.7 GHz on Arc A770
Beyond that, Tom Petersen insists in this video on the potential, in overclocking this time, Arc graphics cards. To do this, he first uses an Arc A750 that he handles in the easiest way in the world with Intel software, without having to leave the game.
On Hitman 3, the Arc 750 runs at 89 frames per second with a GPU frequency of 2400 MHz. With a few clicks, Tom Petersen gets 2580 MHz and the game goes to 93 fps before going up to 2648 MHz and reaching 95 fps. Certainly, the gain is not huge, but it still represents almost 7% more performance, without difficulty.
Tom Petersen specifies that the maximum frequency is even a little higher on the Arc A770 Limited Edition which is, as standard, at 2.1 GHz. You can reach 2.7 GHz on this card without modifying the cooling solution, which would reach a maximum of 39 dBA according to Intel with a GPU between 80 and 90°C.
To clarify, Tom Petersen points out that the frequencies advanced by Intel are frequencies guaranteed to work in practically all situations, but that it is possible to go significantly higher, and this, without needing to be an expert in the matter… We only ask to believe them, that said.
