Intel Pentium 3805U vs Intel Pentium 3550M: comparison
Comparison of Intel Pentium 3805U and Intel Pentium 3550M: key differences and a full specification table.
Key differences
Intel Pentium 3805U has a lower TDP (15 W vs 37 W) and a finer process node (14 nm vs 22 nm).
At the same time, Intel Pentium 3550M has a higher base clock (2.3 GHz vs 1.9 GHz), a higher maximum memory size (32 GB vs 16 GB) and a higher maximum integrated graphics clock (1.1 GHz vs 800 MHz).
Both processors match on: core count (2), thread count (2), 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.
