Arc B770 + Core Ultra 5 245K: how do they pair? is there a gaming bottleneck?
Compatibility analysis, performance by resolution and total build price.
The Arrow Lake Core Ultra 5 245K ensures the Arc B770 is never CPU-limited. An excellent combo for 1440p with room for future upgrades.
What gaming experience can you expect?
This combination's strength is 1440p. With ~66 fps at Ultra you'll enjoy demanding AAA titles — Cyberpunk 2077, Black Myth: Wukong, Alan Wake 2 — with high visual quality and no compromises. At 1080p you have even more headroom (~88 fps), enough to take advantage of a 75–144 Hz monitor. The Core Ultra 5 245K is no bottleneck: with only a 0% bottleneck, the GPU runs at full speed in all scenarios.

GPU — Arc B770
The Arc B770 performs well today, but in 1–2 years the most demanding games will pressure its 16 GB of VRAM. A jump to the mid-high range will be interesting.
CPU — Core Ultra 5 245K
The Core Ultra 5 245K is not the bottleneck in this build. When you upgrade the GPU, this processor will still be valid.
