Intel Arc A750 and Arc 770 reviews released – graphics cards with potential but terrible drivers

The path of the Intel Arc A7 graphics cards to the market was long. The company originally planned to release them in the first half of the year, but something went wrong. As a result, in a week, on October 12, Intel will start selling its most productive graphics cards – Arc A750 and A770. Meanwhile, specialized resources have published reviews of these accelerators, comparing them with the solutions of competitors – and the new products have proven themselves quite well.

The Intel Arc A750 and A770 are based on ACM G10 GPUs with 28 and 32 Xe cores, respectively (3584 and 4096 FP32 units, 28 and 32 ray tracing units, and 480 and 512 XMX matrix engines). The frequencies are almost the same – 2050 and 2100 MHz, respectively. The Arc A750 graphics card is offered with 8 GB GDDR6 (16 GHz), while the Arc A770 is offered with 8 or 16 GB GDDR6 (16 or 17.5 GHz). In all cases, a 256-bit bus is used and memory bandwidth of 512 or 560 GB / s.

Intel itself counters the NVIDIA GeForce RTX 3060 graphics card with both the Arc A750 and the Arc A770, and tests confirm that both innovations are generally faster than the stated competitor. According to a review by Tom’s Hardware, the Arc A750 and A770 graphics cards were on average faster than the GeForce RTX in eight games with Full HD (1920 × 1080 pixels) and Quad HD (2560 × 1440 pixels) resolutions 3060 and Radeon RX 6600. At the same time, the GeForce RTX 3060 Ti and Radeon RX 6650 XT outperformed both Intel graphics cards.

It should be noted that Intel graphics cards are able to provide a frequency of more than 60 FPS in almost all games in Full HD, and they also conquer this level in some games in Quad HD. In addition, Arc A750 and A770 are capable of “pulling” games in 4K (3840 × 2160 pixels), but we’re not talking about 60 FPS here. In all cases, the tests were carried out with the maximum graphics settings.

At the same time, tests have shown that Intel graphics cards are extremely dependent on the API used. And Intel has warned about this, but the situation is still uncomfortably noticeable. As tests by Digital Foundry’s YouTube channel showed, when switching from DirectX 12 to DirectX 11, the frame rate in Shadow of Tomb Rider dropped drastically – in places from 120 to 48 FPS. The situation is a bit better for Control, but there is still a drawdown.


The tests of the PCWorld portal are interesting, as the Arc A770 graphics card was also tested with the ReBAR function deactivated, which gives the PC CPU full access to the graphics card memory. And the presence of this technology turned out to be extremely important for new video cards (Intel itself insists). With ReBAR disabled, the older Arc A770 proves to be slower than the Arc A750, and in places the FPS drop can be described as catastrophic. This is also confirmed by the tests by Digital Foundry: Without ReBAR in Assassin’s Creed Unity, the graphics card simply produces a slide show instead of gameplay.

But Intel graphics cards also have good sides. The older Arc A770 performed best in Red Dead Redemption 2 via the Vulkan API – here in Full HD resolution it turned out to be faster than the GeForce RTX 3060 Ti and even the Radeon RX 6700 XT. The Arc A750 and A770 also performed reasonably well in ray tracing games. According to the average test results, they again proved to be faster than the GeForce RTX 3060, and also outperformed the Radeon RX 6700 XT and even the RX 6750 XT.

It is also impossible not to mention Intel XeSS AI scaling technology, which is analogous to AMD FSR 2.0 and NVIDIA DLSS 2.0 solutions. Portal Tom’s Hardware didn’t start by comparing the performance of the A750 and A770 with and without XeSS to other graphics cards, but just showing what an increase the technology can offer. And the numbers are impressive – in 4K, XeSS technology allows graphics cards to deliver playable FPS, almost doubling the frame rate!

In general, as previously reported, Intel has big problems with drivers for Arc graphics cards. Incidentally, the installation itself is problematic – Nexus gamers are faced with the graphics card displaying a black screen until the drivers are installed. But what if there is no built-in graphics card? The question is rhetorical. Note, however, that at least some of the problems described above can be solved programmatically. This gives hope that the potential of the Arc A750 and A770 will be revealed in the future. But until now, reviewers don’t recommend buying these graphics cards unless we want to feel like beta testers.
