CPU bottleneck check, compatible CPUs, and AI models it can run
Intel Arc A770 8GB / Intel made / Arc / Released 2022 Also known as: ArcA770 / A770
Intel Arc A770 8GB (Intel, released in 2022, also listed as ArcA770 / A770) is a graphics card with a performance score of 14,000 and 8GB of VRAM, TDP 225W. If CPU compatibility and performance balance are poor, a CPU bottleneck occurs, preventing Arc A770 8GB from reaching its full potential. In our estimate, the CPUs that pair best with Arc A770 8GB are Intel: Core i5-8400 (estimated bottleneck: about 0%), and AMD: Ryzen 7 2700X (about 0%). Below are the top 10 compatible CPUs, CPUs to avoid, and generative AI models supported by this amount of VRAM.
CPUs are ordered by proximity to the ideal CPU:GPU ratio of 0.9:1. A lower bottleneck percentage means more of the GPU’s performance can be used.
The Bottleneck Checker opens with Intel Arc A770 8GB already selected.
Arc A770 8GB (ArcA770 / A770) has a performance score of 14,000 points. Using the same CPU:GPU ≈ 0.9:1 standard as the checker, compatibility by CPU score is shown below.
| Example CPUs to Pair | Rating | What It Means |
|---|---|---|
| Ryzen 5 2600X、Ryzen 7 2700、Core i5-8500 | Great Match: 10% or Less | Optimal balance. Nearly all of Arc A770 8GB performance can be used |
| Core i7-6700、Core i7-4790、Ryzen 3 2300X | Acceptable: 10–25% | Practical with no major issue. Consider a future upgrade if targeting high fps. |
| Core i5-7600K、AMD FX-8350、Core i7-4770 | CPU Too Weak: Over 25% | A clear CPU bottleneck. Much of the GPU performance is wasted |
| Core i7-10700、Core i7-10700F、Core i5-10600K | CPU Overkill | Likely overkill for gaming |
Note: Perceived results vary by resolution and game (GPU matters more at 4K, while CPU matters more at high-fps Full HD). For an exact estimate, use the Bottleneck Checker.
Runs Comfortably: Meets recommended VRAM / Barely Runs: Meets minimum VRAM (lower quality or quantization may be needed)

In our estimate, the best-balanced options are Core i5-8400 for Intel (estimated bottleneck: about 0%) and Ryzen 7 2700X for AMD (about 0%). A CPU-to-GPU performance ratio near 0.9:1 tends to use both parts effectively. See the top 10 compatible CPUs in the table on this page.
As a guide, CPUs such as Core i5-7600K、AMD FX-8350、Core i7-4770、Core i7-3770K push the bottleneck above 25% and waste much of the Intel Arc A770 8GB performance. On the other hand, CPUs such as Core i7-10700、Core i7-10700F、Core i5-10600K are likely overkill for gaming.
Intel Arc A770 8GB has 8GB of VRAM. It can comfortably run about 53 models, including Stable Diffusion and LLMs (for example, SD 1.5 (Q4 quantized), Stable Diffusion 1.5, SDXL Turbo).
Intel Arc A770 8GB has a power draw (TDP) of 225W. Choose a power supply that covers the GPU TDP plus CPU and other component power draw, with additional headroom. Check the actual CPU pairing balance in the bottleneck diagnosis above.
Its performance score is 14,000 points. CPU balance matters for gaming, while VRAM (8GB) matters for generative AI. Use the top 10 CPU list and AI model list above to check your use case.
