Intel Xeon E5503 vs Intel Xeon E5507: comparison
Comparison of Intel Xeon E5503 and Intel Xeon E5507: key differences and a full specification table.
Key differences
Intel Xeon E5507 has more cores (4 vs 2), more threads (4 vs 2) and a higher base clock (2.26 GHz vs 2 GHz).
Both processors match on: L3 cache (4 MB), TDP (80 W), process node (45 nm), maximum memory size (144 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.
