Intel Celeron 4205U vs Intel Celeron 3867U: comparison
Comparison of Intel Celeron 4205U and Intel Celeron 3867U: key differences and a full specification table.
Key differences
Intel Celeron 4205U has a higher maximum memory size (64 GB vs 32 GB).
At the same time, Intel Celeron 3867U has a newer PCIe version (3 vs 2).
Both processors match on: core count (2), thread count (2), base clock (1.8 GHz), L3 cache (2 MB), TDP (15 W), process node (14 nm), memory channels (2), maximum integrated graphics clock (900 MHz).
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.
