Intel has officially presented their ARC A750 and A770 models for evaluation. This article will focus on the A770. The latest graphics card from Intel is aimed at the mainstream market, positioned just above the Radeon RX 6600 and GeForce RTX 3060. Intel has faced significant challenges during its product launch. Initially, the company introduced only the slower A380 SKUs in the Asian market, and upon the release of the ARC A770, it encountered issues with low availability. Additionally, various software problems have affected the hardware releases. A contributing factor to the delayed reviews is the insufficient number of sample kits provided by Intel. As a result, content creators on platforms like YouTube were prioritized over more technical media outlets, although there were some exceptions. On a positive note, since the launch, Intel has made notable improvements to its drivers. Our assessment indicates that the ARC A700 series provides a relatively stable platform, demonstrating strong performance in DX12 games, while its performance in DX11 games remains less impressive. It has come to our attention that the A770 was introduced in two distinct configurations: one with 8GB of memory and another with 16GB. The A770 Limited Edition currently under evaluation, while the standard 8GB model is available. Additionally, there is the A750, which features a slightly reduced specification and. It is important to note that these are the manufacturer's suggested retail prices, and actual availability at these prices is not found among retailers. In the United States, one might encounter the A770 conversely, in the European market, the cost may approach. Such pricing is excessive for a product positioned within this performance category.

Upon first glance, it is evident that Intel has successfully designed an aesthetically pleasing graphics card. The A770 features 32 Xe cores and 32 ray tracing units, operating at a frequency of 2100 MHz, with a maximum power delivery capacity of 225 watts. It is compatible with ray tracing and is equipped with robust first-generation RT cores. The 16GB variant offers a memory bandwidth of up to 560 GB/s, while the 8GB variant provides half the VRAM and a 9% reduction in memory bandwidth, utilizing 16 Gbps GDDR6 instead of 17.5 Gbps GDDR6. In contrast, the A750 is equipped with fewer cores and ray tracing units, totaling 28, operates at a frequency that is 50 MHz lower, and includes 8GB of VRAM, maintaining the same memory bandwidth of 512 GB/s, with a total board power rating of 225 watts. It is important to note that all models feature a 256-bit wide memory bus, support PCIe 4.0 x16, and require both an 8-pin and a 6-pin power input.

Intel customers will seek or may require a PC that is compatible with ReBAR.

It is important to recognize that these graphics cards rely heavily on the functionality of Resize BAR. Therefore, if you intend to install an Intel ARC card, your computer should ideally be no more than a few years old. Ensure that your motherboard's BIOS is updated to the latest version and that this feature is enabled. While the cards will still operate without it, you can expect a significant decline in performance. The Arc A770 and A750 require a CPU from Intel's 10th generation or AMD's Ryzen 3000 series or newer. The Arc Alchemist series benefits substantially from Resizable BAR, which is a feature found in processors from recent generations. Although these cards can function with older CPUs, their performance will be considerably diminished if ReBAR is disabled. We did not conduct a complete retest of our benchmark suite, as we observed performance variations of up to 25% in several games. For this review, we will focus on Intel reference cards, also known as Limited Edition, and we even had to remove the engineering sample labels for our analysis.
