Intel Pentium 3558U vs Intel Pentium 3550M: comparison
Comparison of Intel Pentium 3558U and Intel Pentium 3550M: key differences and a full specification table.
Key differences
Intel Pentium 3558U has a lower TDP (15 W vs 37 W).
At the same time, Intel Pentium 3550M has a higher base clock (2.3 GHz vs 1.7 GHz), a higher maximum memory size (32 GB vs 16 GB) and a higher maximum integrated graphics clock (1.1 GHz vs 1 GHz).
Both processors match on: core count (2), thread count (2), L3 cache (2 MB), process node (22 nm), 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.
