Performance comparison: which is faster?
Xeon Gold 6248R (Intel, 2019) and Xeon E3-1280 v6 (Intel, 2017) 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 Gold 6248R is about 150% faster
The sockets differ (LGA3647 / LGA1151), 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 Gold 6248R | Xeon E3-1280 v6 |
|---|---|---|
| Performance Score | 35,000 | 14,000 |
| Generation | Xeon | Xeon |
| Socket | LGA3647 | LGA1151 |
| Release Year | 2019 | 2017 |
| Type | Server | Server |
| Compatible GPU Example | Radeon RX 6700 | Radeon RX 6650 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Xeon Gold 6248R |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | Xeon E3-1280 v6 (the lower model is often sufficient) |
Xeon Gold 6248R is about 150% higher by score (Xeon Gold 6248R: 35000 points / Xeon E3-1280 v6: 14000 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 (LGA3647 / LGA1151), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 6700 pairs well with Xeon Gold 6248R and Radeon RX 6650 XT pairs well with Xeon E3-1280 v6. If either GPU is too strong or too weak, one part holds the other back.
