Intel overclocks the Arc A750 to 2.7GHz with a factory air cooler


In the context of: Intel Marketer Ryan Schrute joined veteran engineer Tom Petersen in the lab for further information on upcoming Arc Alchemist GPUs. This time they researched the cooling capacity and overclocking potential of the Arc A750 and Arc A770 Limited Edition cards.

For some contexts, Limited Edition cards are just Intel’s version of Nvidia’s Founder Edition cards – they are neither special nor limited. Schrute confirmed that they will be available from day one and in large quantities.

So the question is: Do you want one? Intel’s first foray into graphics card making, is It seems like They have done a decent job. Shrout and Petersen mainly focus on the Limited Edition A750 in this video, but from the looks of it, the Limited Edition uses an A770 PCB and a similar coolant.

The radiator itself is a dense assembly of aluminum fins sandwiched between two fans and a large copper vapor chamber. The vapor chamber contacts the GPU itself as well as the GDDR6 and VRMs, feeding four flat 10 x 3mm heatpipes that travel sideways through the card.

Under the radiator, the PCB contains the 8-pin and 6-pin connectors that feed the six VRMs located to the right of the eight GDDR6 modules that surround the GPU. An HDMI 2.1 port and three DisplayPort 2.0 ports provide output.

Petersen says the board is designed with excessive cooling that makes overclocking possible. To prove his point, he fired a machine with an A750 and took a shot at overclocking with Arc Control software.

As far as the overclocking methodology goes, Petersen isn’t the best. He started with the unexplained and meaningless “performance boost” slider, and when he pushed that higher stop affecting clock speed, he raised the power limit to the max, 228 watts, then began to gradually raise the voltage offset, eventually declaring himself It ended when the GPU exceeded 2700MHz at the 50mV offset.

There are no stress tests and no temperature tests. There is no explanation how to roll back the settings after pushing too far and causing the system to crash as well.

Petersen actually overclocked while Hitman 3 was running in the background – that’s kind of a stability gauge. Use the game to measure the performance increase from overclocking. At default settings, the GPU clocked itself at 2400MHz and clocked in at around 90fps. At 2719MHz, it hit around 96fps, resulting in a roughly 7% performance increase with a 13% overclock, which isn’t too bad.

It’s a bit odd that the A750 was running at 2400MHz to begin with, in fact. Game Clock – The only clock speed Intel offers Spec Sheet – 2050 MHz. Compared to this, 2400MHz represents an overclocking of 17% and 2719MHz represents an overclocking of 33%.

At the end of the video, Schrute and Petersen finally address the elephant in the room: price and availability. All they say is this: “We know you’re eager to get to that. We’re eager to share it too—it will be very soon.”
