Intel Xeon X5677 vs Intel Xeon X5680: comparison
Comparison of Intel Xeon X5677 and Intel Xeon X5680: key differences and a full specification table.
Key differences
Intel Xeon X5677 has a higher base clock (3.46 GHz vs 3.33 GHz) and a higher maximum clock (3.73 GHz vs 3.6 GHz).
At the same time, Intel Xeon X5680 has more cores (6 vs 4) and more threads (12 vs 8).
Both processors match on: L3 cache (12 MB), TDP (130 W), process node (32 nm), maximum memory size (288 GB), memory channels (3).
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.
