Intel discusses overclocking on Arc A770 video card

The Intel Arc A770, the heaviest model from Intel’s first series of video cards, would run at 2.7 GHz without too much effort, according to the GPU team.

That’s what Intel engineer Tom Petersen claimed in an extensive interview with HotHardware. In the video call, Petersen discusses, among other things, the great things behind Intel’s ray tracing pipeline and its own XeSS upscaling technology, but especially the overclockability of the flagship gave completely new insights.

By default, the Intel Arc A770 runs at a graphics clock of 2.1 GHz, but it could “with some tweaks in the [koelings]curve and some undervolting” can quickly be clocked 600 MHz higher. “And that is purely on air[koeling]Petersen underlined again.

Even before claiming the higher clock speed, it was already assured that Intel had not picked the most favorable gpu from the warehouse in Santa Clara. “We could have done that, but we were just experimenting with a random one [Arc A770].”

Temperatures and noise production were not discussed, but Petersen himself was apparently also surprised with the consumption of the overclocked A770 during a test phase with Hitman 3. With the chip at 2.7 GHz, the entire video card would have peaked no higher than 228 watts — just 3 watts above the official TGP: 225 watts.

During the conversation, Petersen also shared new presentation slides, in which the specifications of the Arc A770 and Arc A750 have been slightly tightened up. For example, the dichotomy of the A770 — with 8 GB or 16 GB of GDDR6 memory — can now also be found in Intel’s new information material. The updated overview was posted on the Intel Arc website, but can also be seen below.

Remarkably enough, the Arc A750 now has exactly the same TGP as the Arc A770: 225 watts. That while both the amount of Xe cores and the clock speed of the A750 are a bit lower. Both video cards basically run, just like the slightly lower Arc A580 (175 watts), on the same ACM-G10 chipset from Intel.

Despite all the transparent anecdotes, claims and new specifications, Petersen obviously dodged the only uncertainty for Intel Arc: a precise release date. A month ago, Petersen himself spoke of a “later this year” appearance for Arc desktop cards; at the beginning of this month, that was tightened to “very soon” for at least the Arc A7 segment.

Intel hinted in official reporting that the new cards will not necessarily appear exclusively in China, as was already the case for the Arc A380 in June. The first desktop card, like many Intel laptop GPUs, appeared primarily in the Asian market. In any case, Germany was mentioned as “important territory” for Intel’s more powerful line of video cards.
