“AMD Radeon or Nvidia Geforce?”: This question is no longer relevant, at least in the price range between 250 and 400 euros. Anyone looking for a new graphics card to play with here has a third option: Intel Arc. The processor giant has done a lot in recent months to make its young graphics card portfolio competitive. As we explain in previous articles, thanks to many driver updates and a price reduction, an Arc graphics card is a valid option in the mid-range GPU. But which model is optimal? We answer this question in this article. Not only the three Arc versions A770 16GB, A770 8GB and A750 8GB were used for comparison, but of course also various Radeon and Geforce graphics cards.
This article is the third in a new series on Arc graphics cards. In the first part, we dealt with the game compatibility of the Intel driver in 2023, among other things. In the second part, we subjected the Arc graphics cards to a comprehensive post-test, with benchmarks from DirectX 9 to the latest ray tracing. Part 3 – what you are reading now – rounds off the review with a comparison of the A770 16GB and A770 8GB.
Intel Arc: Market Overview
Intel is new to the graphics card market and has yet to earn its stripes. Not only the customers, but also potential partners are reluctant, the selection of Arc graphics cards is still manageable – especially in Germany. While in other markets, for example, the manufacturer Gunnir is represented with Arc graphics cards, there is no trace in this country. The big brands, which dominate the AMD and Nvidia market with their own designs, stand out with particular restraint. Apart from an MSI variant of the Arc A380, which apparently is only available in China, none of the big players have released their own Arc designs. That also has something good: If you are interested in an A770, A750 or A380, you only have to choose between a few options. The intermediate model Arc A580, which Intel is still promising in 2022, is still a long time coming and, according to our estimates, will no longer appear. We assume that Intel will only release the 5 model with the upcoming Alchemist refresh in a few months – as long as the recently leaked roadmap is authentic.
If you want to buy an Arc graphics card for gaming, you basically only have three manufacturers to choose from: Acer, Asrock and Intel. Things are spiced up a bit by the fact that not all three manufacturers offer the same models. Let’s start at the top, with the Arc top model A770 16GB. So far, this is only offered by Intel itself and the graphics card newcomer Acer. The Acer A770 Predator Bifrost OC is the only model that combines 16 GiByte and factory overclocking (achieved through an increased power limit), while the Intel A770 Limited Edition is, quite simply, the reference card. What both models have in common is not only the amount of memory of 16 GiByte, but also the associated memory clock of 2,187 MHz or 17.5 Gigatransfers per second. Faster Arc graphics cards do not currently exist.
According to Intel, the board partners of the Arc A770 and the smaller model A750 can decide which memory configuration they use: 16 GiByte with 17.5 GT/s or 8 GiByte with 16 GT/s. The latter is an important differentiator; 8 GiByte models not only have half the memory, but also work with a reduced transfer rate from 560 to 512 GB/s. Interested parties don’t have a real choice, because there is currently only one graphics card that combines the features “A770” and “8 GiByte”: the Asrock A770 Phantom Gaming D 8GB OC. However, there is no Arc A750 with 16 GiByte, here you have the choice between the Intel Arc A750 Limited Edition and the Asrock A750 Challenger D 8GB OC. Here, without exception, 8 GiByte with 16 GT/s are offered.
That’s the full arc gaming portfolio, which we deliberately don’t include the entry-level A380. Since the following is about graphics cards for gamers that cost between around 270 and 400 euros, we summarize the most important performance features in a table. Factory overclocked models vary slightly.

The following article page gets down to business: What does an Arc A770 8GB do compared to its big sister Arc A770 16GB? And how does the cheaper Arc A750 perform? Numerous benchmarks with and without ray tracing provide information. Of course, we pay special attention to the storage capacity, because there are interesting things to report here.
