Intel Celeron G3900 vs Intel Celeron G1840: comparison
Comparison of Intel Celeron G3900 and Intel Celeron G1840: key differences and a full specification table.
Key differences
Intel Celeron G3900 has a lower TDP (51 W vs 53 W), a finer process node (14 nm vs 22 nm) and a higher maximum memory size (64 GB vs 32 GB).
At the same time, Intel Celeron G1840 has a higher maximum integrated graphics clock (1.05 GHz vs 950 MHz).
Both processors match on: core count (2), thread count (2), base clock (2.8 GHz), memory channels (2), 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.
