About Intel Core i5-2557M

The Intel Core i5-2557M is a 2‑core, 4‑thread mobile processor built on Intel’s 32 nm Sandy Bridge micro‑architecture, delivering a modest 1.7 GHz base clock that can boost to roughly 2.7 GHz under load. Its 17 W TDP keeps power draw low enough for thin‑and‑light laptops while still offering enough headroom for short bursts of performance. In synthetic testing the chip reaches 1,381 points in Cinebench R23 multi‑core and 776 points in Geekbench multi‑core, with single‑core scores of 195 and 382 respectively, showing a balanced but not spectacular capability. These figures slot the processor into the low‑mid tier of its era, making it competent for everyday tasks and light creative work. Even though newer cores have eclipsed it, the i5‑2557M still surprises with respectable throughput for a 2011 design.

The 2557M mobile chip pairs with a dual‑channel DDR3 memory subsystem that runs up to 1333 MHz and shares a 3 MB L3 cache between the cores, providing enough bandwidth for typical office suites and web browsing. Its modest power envelope translates into solid battery life, a key factor for users who value portability without constantly hunting for an outlet. Best suited for productivity, media consumption, light photo editing, and older titles that don’t demand high frame rates, the processor shines in scenarios where efficiency outweighs raw horsepower. This Sandy Bridge dual‑core also manages to pull 580 points in Cinebench R20 multi‑core, confirming that its architecture still handles multi‑threaded workloads with reasonable grace. If you’re on the hunt for a budget ultrabook that feels like a nostalgic experiment, the i5‑2557M offers a curious blend of legacy performance and energy‑friendly operation.
