While it is not a custom ASRock version that has been available earlier, it is still a pretty sweet deal, as this is Intel's reference version with dual-slot dual-fan cooler. As spotted by Videocardz.com, the $199 is the lowest price seen for this graphics card.
In case you missed it earlier, the Arc A750 is based on a cut-down version of the ACM-G10 GPU, packing 28 Xe cores, or 3584 Stream Processors, and comes with 8GB of 16Gbps GDDR6 memory on a 256-bit memory interface, leaving it with 512GB/s of memory bandwidth.
In terms of performance, the Arc A750 8GB should be better than the Geforce RTX 3060. Of course, the newly launched RTX 4060 Ti is faster, but it also starts at $399. AMD's Radeon RX 7600 8GB should launch soon as well, with SEP set at $269, and we have yet to see where it fits with its performance.
So far, only the Arc A750 got the discount, while the Arc A770 remains at $329/$349.
