Intel Celeron 787 vs Intel Celeron 857: comparison
Comparison of Intel Celeron 787 and Intel Celeron 857: key differences and a full specification table.
Key differences
Intel Celeron 787 has a higher base clock (1.3 GHz vs 1.2 GHz).
At the same time, Intel Celeron 857 has more cores (2 vs 1), more threads (2 vs 1), a larger L3 cache (2 MB vs 1.5 MB) and a higher maximum integrated graphics clock (1 GHz vs 950 MHz).
Both processors match on: TDP (17 W), process node (32 nm), maximum memory size (16 GB), 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.
