Intel Pentium B915C vs Intel Xeon E3-1105C: comparison
Comparison of Intel Pentium B915C and Intel Xeon E3-1105C: key differences and a full specification table.
Key differences
Intel Pentium B915C has a higher base clock (1.5 GHz vs 1 GHz) and a lower TDP (15 W vs 25 W).
At the same time, Intel Xeon E3-1105C has more cores (4 vs 2), more threads (8 vs 4) and a larger L3 cache (6 MB vs 3 MB).
Both processors match on: 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.
