Performance comparison: which is faster?
Core 2 Quad Q9650 (Intel, 2008) and Core 2 Quad Q6700 (Intel, 2008) 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: 2 Quad Q9650 is about 20.7% faster
Both use the same LGA775 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 | 2 Quad Q9650 | 2 Quad Q6700 |
|---|---|---|
| Performance Score | 3,500 | 2,900 |
| Generation | Core 2 | Core 2 |
| Socket | LGA775 | LGA775 |
| Release Year | 2008 | 2008 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce GTX 480 | Radeon R7 360 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | 2 Quad Q9650 |
| Upgrade while reusing the current motherboard | Either works (same LGA775 socket) |
| Prioritize value and adequate performance | 2 Quad Q6700 (the lower model is often sufficient) |
2 Quad Q9650 is about 20.7% higher by score (2 Quad Q9650: 3500 points / 2 Quad Q6700: 2900 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 Core 2-generation CPUs.Both use the same LGA775 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce GTX 480 pairs well with 2 Quad Q9650 and Radeon R7 360 pairs well with 2 Quad Q6700. If either GPU is too strong or too weak, one part holds the other back.
