Intel Xeon E7-2850 vs Intel Xeon E7-8837: comparison
Comparison of Intel Xeon E7-2850 and Intel Xeon E7-8837: key differences and a full specification table.
Key differences
Intel Xeon E7-2850 has more cores (10 vs 8) and more threads (20 vs 8).
At the same time, Intel Xeon E7-8837 has a higher base clock (2.66 GHz vs 2 GHz), a higher maximum clock (2.8 GHz vs 2.4 GHz) and a higher maximum memory size (4 TB vs 1 TB).
Both processors match on: L3 cache (24 MB), TDP (130 W), process node (32 nm), memory channels (4).
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.
