Intel Xeon D-2123IT vs Intel Xeon D-2145NT: comparison
Comparison of Intel Xeon D-2123IT and Intel Xeon D-2145NT: key differences and a full specification table.
Key differences
Intel Xeon D-2123IT has a higher base clock (2.2 GHz vs 1.9 GHz) and a lower TDP (60 W vs 65 W).
At the same time, Intel Xeon D-2145NT has more cores (8 vs 4) and more threads (16 vs 8).
Both processors match on: maximum clock (3 GHz), process node (14 nm), maximum memory size (512 GB), 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.
