Performance comparison: which is faster?
Core i3-8350K (Intel, 2018) and Core i3-8100 (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: i3-8350K is about 18.1% faster
Both use the same LGA1151 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.
| Item | i3-8350K | i3-8100 |
|---|---|---|
| Performance Score | 8,500 | 7,200 |
| Generation | 8th Gen | 8th Gen |
| Socket | LGA1151 | LGA1151 |
| Release Year | 2018 | 2018 |
| Type | Desktop | Desktop |
| Compatible GPU Example | Radeon RX 5500 XT | Radeon RX 590 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i3-8350K |
| Upgrade while reusing the current motherboard | Either works (same LGA1151 socket) |
| Prioritize value and adequate performance | i3-8100 (the lower model is often sufficient) |
i3-8350K is about 18.1% higher by score (i3-8350K: 8500 points / i3-8100: 7200 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 8th Gen-generation CPUs.Both use the same LGA1151 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 5500 XT pairs well with i3-8350K and Radeon RX 590 pairs well with i3-8100. If either GPU is too strong or too weak, one part holds the other back.
