Intel Xeon E7-4820 v2 vs Intel Xeon E7-4830 v2: comparison
Comparison of Intel Xeon E7-4820 v2 and Intel Xeon E7-4830 v2: key differences and a full specification table.
Key differences
Intel Xeon E7-4830 v2 has more cores (10 vs 8), more threads (20 vs 16), a higher base clock (2.2 GHz vs 2 GHz) and a higher maximum clock (2.7 GHz vs 2.5 GHz).
Both processors match on: TDP (105 W), process node (22 nm), maximum memory size (1.5 TB), memory channels (4), PCIe version (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.
