Performance comparison: which is faster?
Xeon Platinum 8490H (Intel, 2023) and Xeon Platinum 8480+ (Intel, 2023) 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 15.8% faster
Both use the same LGA4677 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 | Xeon Platinum 8490H | Xeon Platinum 8480+ |
|---|---|---|
| Performance Score | 110,000 | 95,000 |
| Generation | Xeon | Xeon |
| Socket | LGA4677 | LGA4677 |
| Release Year | 2023 | 2023 |
| Type | Server | Server |
| Compatible GPU Example | GeForce RTX 4060 Laptop GPU | Radeon RX 6700 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 | Either works (same LGA4677 socket) |
| Prioritize value and adequate performance | Xeon Platinum 8480+ (the lower model is often sufficient) |
Xeon Platinum 8490H is about 15.8% higher by score (Xeon Platinum 8490H: 110000 points / Xeon Platinum 8480+: 95000 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.Both use the same LGA4677 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 4060 Laptop GPU pairs well with Xeon Platinum 8490H and Radeon RX 6700 XT pairs well with Xeon Platinum 8480+. If either GPU is too strong or too weak, one part holds the other back.
