Performance comparison: which is faster?
Xeon Platinum 8490H (Intel, 2023) and Xeon Platinum 8380 (Intel, 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: Xeon Platinum 8490H is about 57.1% faster
The sockets differ (LGA4677 / LGA4189), 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 | Xeon Platinum 8490H | Xeon Platinum 8380 |
|---|---|---|
| Performance Score | 110,000 | 70,000 |
| Generation | Xeon | Xeon |
| Socket | LGA4677 | LGA4189 |
| Release Year | 2023 | 2021 |
| Type | Server | Server |
| Compatible GPU Example | GeForce RTX 4060 Laptop GPU | Radeon RX 6650 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Xeon Platinum 8490H |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | Xeon Platinum 8380 (the lower model is often sufficient) |
Xeon Platinum 8490H is about 57.1% higher by score (Xeon Platinum 8490H: 110000 points / Xeon Platinum 8380: 70000 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 Xeon-generation CPUs.The sockets differ (LGA4677 / LGA4189), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 4060 Laptop GPU pairs well with Xeon Platinum 8490H and Radeon RX 6650 XT pairs well with Xeon Platinum 8380. If either GPU is too strong or too weak, one part holds the other back.
