Performance comparison: which is faster?
Core i7-14700K (Intel, 2024) and Core i9-14900HX (Intel, 2024) 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: i7-14700K is about 8.3% faster
The sockets differ (LGA1700 / BGA), 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 | i7-14700K | i9-14900HX |
|---|---|---|
| Performance Score | 52,000 | 48,000 |
| Generation | 14th Gen | 14th Gen |
| Socket | LGA1700 | BGA |
| Release Year | 2024 | 2024 |
| Type | Desktop | Laptop |
| Compatible GPU Example | Radeon RX 7900 GRE | GeForce RTX 4090 Laptop GPU |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | i7-14700K |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | i9-14900HX (the lower model is often sufficient) |
i7-14700K is about 8.3% higher by score (i7-14700K: 52000 points / i9-14900HX: 48000 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 14th Gen-generation CPUs.The sockets differ (LGA1700 / BGA), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 7900 GRE pairs well with i7-14700K and GeForce RTX 4090 Laptop GPU pairs well with i9-14900HX. If either GPU is too strong or too weak, one part holds the other back.
