Performance comparison: which is faster?
Celeron N5105 (Intel, 2021) and Celeron G5905 (Intel, 2021) 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: Celeron N5105 is about 18.4% faster
The sockets differ (BGA / LGA1200), so switching requires a motherboard replacement. 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.
| Item | Celeron N5105 | Celeron G5905 |
|---|---|---|
| Performance Score | 4,500 | 3,800 |
| Generation | Celeron | Celeron |
| Socket | BGA | LGA1200 |
| Release Year | 2021 | 2021 |
| Type | Laptop | Desktop |
| Compatible GPU Example | GeForce RTX 4050 Laptop GPU | GeForce GTX 950 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Celeron N5105 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | Celeron G5905 (the lower model is often sufficient) |
Celeron N5105 is about 18.4% higher by score (Celeron N5105: 4500 points / Celeron G5905: 3800 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.
Both are Celeron-generation CPUs.The sockets differ (BGA / LGA1200), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 4050 Laptop GPU pairs well with Celeron N5105 and GeForce GTX 950 pairs well with Celeron G5905. If either GPU is too strong or too weak, one part holds the other back.
