Intel Celeron G3902E vs Intel Celeron G1820TE: comparison
Comparison of Intel Celeron G3902E and Intel Celeron G1820TE: key differences and a full specification table.
Key differences
Intel Celeron G3902E has a lower TDP (25 W vs 35 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 G1820TE has a higher base clock (2.2 GHz vs 1.6 GHz) and a higher maximum integrated graphics clock (1 GHz vs 950 MHz).
Both processors match on: core count (2), thread count (2), L3 cache (2 MB), 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.
