CPU Comparison

Intel Core i5-3320M vs Intel Core i5-2557M

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.

Performance Compared

Productivity

Intel Core i5-3320M28

Handles office apps well but struggles with modern web apps.

Intel Core i5-2557M28

Noticeably slower than standard-voltage Sandy Bridge in sustained workloads due to thermal throttling in thin chassis.

Gaming

Intel Core i5-3320MBest18

Can play older titles like CS:GO on low settings, but nothing modern.

Intel Core i5-2557M12

Even weaker than the 35 W variant due to lower sustained clocks. Not viable for any modern game.

Virtualization

Intel Core i5-3320MBest20

Basic VM support, limited by 2 cores.

Intel Core i5-2557M15

Technically supports VT-x but too slow for practical virtualization use.

Efficiency

Intel Core i5-3320M40

Decent efficiency for 2012, but poor by modern mobile standards.

Intel Core i5-2557M40

17 W TDP was efficient for 2011 but modern chips deliver 10x the performance at similar power.

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.

The i5-2557M sacrificed significant performance to achieve its 17 W TDP, making it a poor choice even in 2011 for anything beyond basic tasks. Modern low-voltage chips deliver dramatically more performance at similar power levels.

Best for: None, this processor cannot be purchased separately
