Performance comparison: which is faster?
Ryzen 3 3300X (AMD, 2020) and Ryzen 3 5300G (AMD, 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: nearly equal
Both use the same AM4 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 | Ryzen 3 3300X | Ryzen 3 5300G |
|---|---|---|
| Performance Score | 15,000 | 15,000 |
| Generation | Ryzen 3000 | Ryzen 5000 |
| Socket | AM4 | AM4 |
| Release Year | 2020 | 2021 |
| Type | Desktop | Desktop |
| Compatible GPU Example | GeForce RTX 5050 | GeForce RTX 4060 |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Ryzen 3 3300X |
| Upgrade while reusing the current motherboard | Either works (same AM4 socket) |
| Prioritize value and adequate performance | Ryzen 3 3300X (the lower model is often sufficient) |
Their scores are nearly identical (Ryzen 3 3300X: 15000 points / Ryzen 3 5300G: 15000 points). Choose the less expensive option or the one that fits your current motherboard.
Ryzen 3 3300X is Ryzen 3000, while Ryzen 3 5300G is Ryzen 5000.Both use the same AM4 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 5050 pairs well with Ryzen 3 3300X and GeForce RTX 4060 pairs well with Ryzen 3 5300G. If either GPU is too strong or too weak, one part holds the other back.
