Intel Pentium 957 vs Intel Pentium U5400: comparison
Comparison of Intel Pentium 957 and Intel Pentium U5400: key differences and a full specification table.
Key differences
Intel Pentium 957 has a lower TDP (17 W vs 18 W), a higher maximum memory size (8.01 GB vs 8 GB) and a higher maximum integrated graphics clock (800 MHz vs 500 MHz).
At the same time, Intel Pentium U5400 has a larger L3 cache (3 MB vs 2 MB).
Both processors match on: core count (2), thread count (2), base clock (1.2 GHz), process node (32 nm), 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.
