Intel Xeon E3-1245 vs Intel Xeon E3-1280: comparison
Comparison of Intel Xeon E3-1245 and Intel Xeon E3-1280: key differences and a full specification table.
Key differences
Intel Xeon E3-1280 has a higher base clock (3.5 GHz vs 3.3 GHz) and a higher maximum clock (3.9 GHz vs 3.7 GHz).
Both processors match on: core count (4), thread count (8), L3 cache (8 MB), TDP (95 W), process node (32 nm), maximum memory size (32 GB), memory channels (2), PCIe version (2).
These are specification values: they show differences between the models but do not determine a performance winner. For a specific workload, rely on independent benchmarks.
