Intel ARC A770 Gaming and Overclocking Performance
Intel released the Intel Arc brand Alchemist (DG2) discrete graphics card at the end of March, but only last month officially launched its first product for desktop platforms, the entry-level A380. The recently exposed slide shows that there are five ARC A series graphics cards on the desktop platform, namely A770, A750, A580, A380, and A310. The highest-end ARC A770 is positioned similarly to the GeForce RTX 3060 Ti and Radeon RX 6650XT.
Linus Tech Tips recently showed in the video not only the overall appearance of the ARC A770 graphics card but also the gaming and overclocking performance. There are also guests from Intel in the video, including Tom Petersen, an academician responsible for graphics technology innovation, and Ryan Shrout, director of GPU business marketing. This should be the first public demonstration video of the ARC A770 graphics card.
ARC A770 adopts ACM-G10 with complete specifications, with 32 Xe cores, 4096 ALUs and 32 ray tracing units, 16GB GDDR6 video memory, 256-bit bit width, and an 8Pin and a 6Pin external power supply interface. Through the interface of Arc Control, you can see that the core frequency of ARC A770 reaches 2.5GHz, and the GPU power consumption is 190W.
Tom Petersen briefly introduced the game optimization problem of ARC GPU. Intel has adopted a “three-layer optimization” strategy internally: the first layer is the game where ARC GPU runs the best, using DirectX 12 API, such as “Cyberpunk 2077”;
the second layer is DirectX12/Vulkan games that run well on ARC GPU, but there are fewer targeted optimizations; the third layer is games that are not optimized for ARC GPU, mainly DirectX 11 games.
In terms of overclocking, through the +20% performance configuration file, the voltage curve of ARC A770 is adjusted, which can increase the power consumption limit of the graphics card to 285W. The temperature limit was also raised to 125°C, but when it was raised further to +30%, running the game crashed.
