Intel Celeron 847 vs Intel Celeron B800: comparison
Comparison of Intel Celeron 847 and Intel Celeron B800: key differences and a full specification table.
Key differences
Intel Celeron 847 has a lower TDP (17 W vs 35 W).
At the same time, Intel Celeron B800 has a higher base clock (1.5 GHz vs 1.1 GHz) and a higher maximum integrated graphics clock (1 GHz vs 800 MHz).
Both processors match on: core count (2), thread count (2), L3 cache (2 MB), 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.
