Performance comparison: which is faster?
Pentium G3258 (Intel, 2014) and Core i3-2100 (Intel, 2011) 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: Pentium G3258 is about 6.7% faster
The sockets differ (LGA1150 / LGA1155), 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 | Pentium G3258 | i3-2100 |
|---|---|---|
| Performance Score | 3,200 | 3,000 |
| Generation | Pentium | 2nd Gen |
| Socket | LGA1150 | LGA1155 |
| Release Year | 2014 | 2011 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon HD 7850 | GeForce GTX 1030 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Pentium G3258 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i3-2100 (the lower model is often sufficient) |
Pentium G3258 is about 6.7% higher by score (Pentium G3258: 3200 points / i3-2100: 3000 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.
Pentium G3258 is Pentium, while i3-2100 is 2nd Gen.The sockets differ (LGA1150 / LGA1155), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon HD 7850 pairs well with Pentium G3258 and GeForce GTX 1030 pairs well with i3-2100. If either GPU is too strong or too weak, one part holds the other back.
