Core i3-4130T vs Core i5-5257U

Both the Core i3-4130T and Core i5-5257U share an identical 2-core/4-thread configuration. Boost clocks reach 2.9 GHz on the Core i3-4130T versus 3.1 GHz on the Core i5-5257U — a 6.7% clock advantage for the Core i5-5257U (base: 2.9 GHz vs 2.7 GHz). The Core i3-4130T uses the Haswell (2013−2015) architecture (22 nm), while the Core i5-5257U uses Broadwell-U (2015) (14 nm). In PassMark, the Core i3-4130T scores 2,876 against the Core i5-5257U's 2,837 — a 1.4% lead for the Core i3-4130T. Geekbench 6 single-core — the metric most relevant to gaming — records 890 vs 950, a 6.5% lead for the Core i5-5257U that directly translates to higher frame rates. Both processors carry 3 MB (total) of L3 cache.

The Core i3-4130T uses the LGA1150 socket (PCIe 3.0), while the Core i5-5257U uses FCBGA1168 (PCIe 3.0) — making them incompatible on the same motherboard. Maximum memory speed reaches DDR3-1600 on the Core i3-4130T versus LPDDR3 1866 MHz on the Core i5-5257U — the Core i5-5257U supports 200% faster memory, which can translate to measurable gains in memory-sensitive workloads. The Core i3-4130T supports up to 32 GB of RAM compared to 16 GB — 66.7% more capacity for professional workloads. Both feature 2-channel memory with ECC support. PCIe lanes: 16 (Core i3-4130T) vs 12 (Core i5-5257U) — the Core i3-4130T offers 4 more lanes for additional GPUs or NVMe drives. Chipset compatibility: H81,B85,Q85,H87,Q87,Z87,H97,Z97 (Core i3-4130T) and Broadwell-U (Core i5-5257U).

Neither processor supports overclocking. Virtualization support: VT-x, EPT (Core i3-4130T) vs true (Core i5-5257U). Both include integrated graphics — HD Graphics 4400 (Core i3-4130T) and Intel Iris Graphics 6100 (Core i5-5257U) — useful as a fallback for troubleshooting or display output without a dedicated GPU. Primary use case: Core i3-4130T targets Low Power Desktop, Core i5-5257U targets Mobile. Direct competitor: Core i3-4130T rivals A8-7600.
