Intel Core i5-520M Processor SLBNB
Used mobile dual-core Intel Core i5-520M processor (SLBNB, Socket G1 / rPGA988A, up to 2.93 GHz) with Intel HD graphics. Great for older ThinkPad T410 or Dell E6410 laptops.




Intel Core i5-520M SLBNB Mobile Processor (Socket G1 / rPGA988A) – Proven First Generation Core Performance
Are you looking for a reliable replacement part to repair an older laptop, or an affordable way to restore your device's functionality? The mobile Intel Core i5-520M processor (with sSpec code SLBNB) from the first successful Core generation (Arrandale architecture) offers a balanced performance and high stability for everyday office work, web browsing, and schoolwork.
Thanks to Hyper-Threading and Turbo Boost technologies, this processor can efficiently accelerate the responsiveness of older laptops, ensure the stable operation of the Windows operating system, and extend your computer's lifespan without unnecessary expenses on a brand-new machine.
Key Features of the Intel Core i5-520M (SLBNB) Processor
- 2 physical cores and 4 threads with Intel Hyper-Threading technology for smoother multitasking.
- Base frequency of 2.40 GHz with Intel Turbo Boost, which automatically overclocks the processor up to 2.93 GHz under heavy load.
- Integrated Intel HD Graphics core for seamless Full HD video playback and standard multimedia tasks.
- Proven 32nm manufacturing technology guaranteeing a long lifespan with optimal thermal output (35W TDP).
- Designed for widely used laptop motherboards equipped with Socket G1 (rPGA988A).
Smart Technologies for Everyday Multitasking
The Intel Core i5-520M processor features a 3MB Intel Smart Cache. Thanks to the combination of Hyper-Threading (the operating system sees the processor as a quad-core) and Turbo Boost, it dynamically adapts to your current workload. It operates efficiently during word processing but automatically increases power when opening complex files or browsing with multiple tabs, preventing annoying system stuttering.
Integrated Graphics for Standard Multimedia
An integrated Intel HD Graphics core is built directly onto the processor die. It reliably ensures smooth operating system rendering, high-definition video playback on YouTube, and handles less demanding older games. This integrated solution stands out for its high reliability and helps maintain optimal temperatures inside the laptop.
Compatibility and Service Application
This processor with the SLBNB code is exclusively designed for laptops with motherboards featuring a **removable Socket G1 (rPGA988A)** and Intel 5 series chipsets (most commonly HM55, HM57, QM57, PM55).
It represents an ideal replacement part or upgrade for proven, durable corporate laptops of its era, such as:
- Lenovo ThinkPad T410, T510, L412, L512, Edge E420 / E520
- Dell Latitude E6410, E6510, E5410, E5510 / Inspiron N5010
- HP EliteBook 8440p, 8540p / HP ProBook 4520s, 6450b, 6550b
