CPU bottleneck check, compatible CPUs, and AI models it can run
UHD Graphics 770 / Intel made / Integrated / Released 2021 Also known as: UHDGraphics770
UHD Graphics 770 (Intel, released in 2021, also listed as UHDGraphics770) is a graphics card with a performance score of 2,000 and Shared of VRAM. If CPU compatibility and performance balance are poor, a CPU bottleneck occurs, preventing UHD Graphics 770 from reaching its full potential. In our estimate, the CPUs that pair best with UHD Graphics 770 are Intel: Atom x7-Z8750 (estimated bottleneck: about 0%), and AMD: Ryzen 5 8640HS (about 44%). 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 UHD Graphics 770 already selected.
UHD Graphics 770 (UHDGraphics770) has a performance score of 2,000 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 |
|---|---|---|
| Atom x7-Z8750、Celeron N4100 | Great Match: 10% or Less | Optimal balance. Nearly all of UHD Graphics 770 performance can be used |
| — | Acceptable: 10–25% | Practical with no major issue. Consider a future upgrade if targeting high fps. |
| — | CPU Too Weak: Over 25% | A clear CPU bottleneck. Much of the GPU performance is wasted |
| Celeron N5105、Core Ultra 5 135U、Core i5-1335U | 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)
No major AI model in the data can run on this GPU’s 0GB of VRAM. A very large server-grade model would be required.

In our estimate, the best-balanced options are Atom x7-Z8750 for Intel (estimated bottleneck: about 0%) and Ryzen 5 8640HS for AMD (about 44%). 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.
Almost no desktop CPU is slow enough to waste much of the UHD Graphics 770 performance. On the other hand, CPUs such as Celeron N5105、Core Ultra 5 135U、Core i5-1335U are likely overkill for gaming.
UHD Graphics 770 has Shared of VRAM. Its VRAM is somewhat limited for comfortably running major generative AI models, so lightweight or quantized models are the main options.
UHD Graphics 770 is an integrated GPU, so standalone power draw (TDP) is not published. Its consumption is included in the CPU’s total TDP.
Its performance score is 2,000 points. CPU balance matters for gaming, while VRAM (Shared) matters for generative AI. Use the top 10 CPU list and AI model list above to check your use case.
