ASRock’s ARC A770/A750 are based on the ACM-G10 chip, with 32 and 28 Xe cores of the Xe-HPG architecture respectively, of which the core clock of the former is 2.2GHz. Both products are equipped with 8GB of GDDR6 video memory, a video memory bit width is 256 bits, a video memory speed is 16 Gbps, and a dual 8Pin external power supply. ASRock has also confirmed that the A770 Phantom Gaming will not have a 16GB VRAM version.
The A770 Phantom Gaming OC uses the same cooling solution as ASRock’s own Radeon RX 6000 series Phantom Gaming. It was equipped with 5 6mm nickel-plated copper heat pipes, with a copper base plate to contact the GPU, and three double ball bearing fans, it also has RGB lighting effects. The A750 Challenger OC adopts a relatively simple and direct cooling solution, equipped with four 6mm copper heat pipes, which are in direct contact with the GPU, but the number of matching fans is reduced to two.

In addition to the DisplayPort 2.0 interface, ASRock’s ARC graphics cards all have at least one HDMI 2.1 interface, which means that a protocol converter chip is used to convert one of the DisplayPort 2.0 interfaces into an HDMI 2.1 interface. The A750 Challenger OC provides two HDMI interfaces, one of which is the HDMI 2.0b interface and the other is HDMI 2.1 interface.
TechPowerup said that the price of the A770 Phantom Gaming OC is $329, and the price of the A750 Challenger OC is $289, which is consistent with the manufacturer’s suggested retail price announced by Intel, but ASRock has not provided a specific time to market.
