CPU Comparison

Intel Core i5-3320M vs Intel Core i5-2540M

A side-by-side comparison of specs, performance and value. The Intel Core i5-3320M is a dual-core mobile processor launched in June 2012 under the Ivy Bridge generation. Fabricated on a 22nm process, this chip was tailored for business and performance-mainstream laptops. It operates at a base frequency of 2.6 GHz and can turbo boost up to 3.3 GHz, providing a slight edge over the 3210M. With two cores and four threads, it handles multitasking efficiently for its era. The 35-watt TDP ensures it runs cool enough for standard laptop chassis. A key differentiator for this model is the inclusion of Intel Trusted Execution Technology (TXT), making it more appealing for corporate environments where hardware security is a priority. It also features the Intel HD 4000 integrated graphics, which dynamically scale from 650 MHz to 1200 MHz. While it shares the same 3MB L3 cache as its siblings, the higher clock speeds give it a tangible advantage in single-threaded workloads. Though long discontinued, it represents a strong value tier from the Ivy Bridge era.

Our Verdict on Each

A slightly faster, security-enhanced Ivy Bridge mobile chip ideal for old enterprise laptops, but unsuitable for modern use.

Best for: Buying a system with the Intel Core i5-3320M in the modern era is generally not recommended unless you have very specific needs. As a 3rd-generation Intel Core processor, it is fundamentally obsolete for modern workloads and lacks official Windows 11 support. However, if you are looking for a cheap, rugged, used ThinkPad for Linux experimentation, light coding, or as a typewriter, the 3320M is a capable chip. Its 2.6 GHz base and 3.3 GHz turbo, combined with four threads, can handle basic web browsing and document editing if paired with an SSD. Avoid buying this for gaming, streaming, or video editing. The presence of vPro and TXT makes it historically interesting for studying enterprise security, but for daily use, even a low-end Intel Celeron N4000 will offer better efficiency and modern feature support. Only purchase if the price is negligible.
