Performance comparison: which is faster?
Core Ultra 7 165U (Intel, 2024) and Celeron N4100 (Intel, 2018) are compared here. Compare not only scores, but also whether the motherboard can be reused and which GPU class is balanced with each CPU.
Overall performance: Ultra 7 165U is about 580% faster
Both use the same BGA socket, so they can be installed on the same motherboard. For games, performance balance with the GPU (guideline CPU:GPU = 0.9:1) matters more than CPU speed alone.
Relative performance score (higher is faster). Actual speed varies by workload, cooling, and memory configuration.

| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Ultra 7 165U |
| Upgrade while reusing the current motherboard | Either works (same BGA socket) |
| Prioritize value and adequate performance | Celeron N4100 (the lower model is often sufficient) |
Ultra 7 165U is about 580% higher by score (Ultra 7 165U: 17000 points / Celeron N4100: 2500 points). For gaming, the GPU tier usually matters more than a few percent of CPU difference. For CPU-heavy work such as video editing and streaming, choose the faster CPU.
Ultra 7 165U is Core Ultra, while Celeron N4100 is Celeron.Both use the same BGA socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 4070 Laptop GPU pairs well with Ultra 7 165U and GeForce RTX 4050 Laptop GPU pairs well with Celeron N4100. If either GPU is too strong or too weak, one part holds the other back.
