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.
The Intel Core i5-3320M offers 2 cores and 4 threads with a max turbo of 3.3 GHz. It includes Intel HD 4000 graphics and TXT security, making it a solid choice for 2012 business laptops.

Architecture Overview
At the heart of the i5-3320M is the Ivy Bridge microarchitecture, Intel's pioneering 22nm Tri-Gate process. This design reduced power leakage significantly compared to the 32nm Sandy Bridge, allowing higher clock speeds within the same thermal envelope. The processor utilizes a ring bus topology connecting the dual cores, the 3MB L3 cache, and the system agent. Its integrated memory controller natively supports dual-channel DDR3-1600 memory, providing ample bandwidth for the era. The graphics subsystem, Intel HD 4000, features 16 execution units and supports DirectX 11, Quick Sync Video, and InTru 3D. Unlike lower-end chips, the 3320M includes support for Intel vPro and TXT, providing hardware-based security and remote management capabilities. The CPU's PCU (Power Control Unit) manages Turbo Boost 2.0, dynamically allocating thermal headroom to push single cores to 3.3 GHz when needed. The chip also supports advanced vector extensions (AVX) and AES-NI, accelerating encryption and scientific computations.

History
Introduced in mid-2012, the Core i5-3320M was a staple in many enterprise laptops, frequently appearing in Dell Latitudes and Lenovo ThinkPads. It was designed to offer a slight performance bump over the base i5 models while retaining the 35W power limit. During the Windows 8 transition, businesses sought machines with reliable CPU performance and enhanced security.
The 3320M fit this perfectly with its inclusion of TXT and vPro technology. It competed directly against AMD's A8 and A10 APUs, easily outclassing them in CPU-bound tasks but often falling behind in graphical workloads. The Ivy Bridge generation was also known for running slightly warmer than its predecessor due to Intel's use of thermal paste instead of fluxless solder on the IHS (though this mattered less for mobile BGA/PGA chips).
Ultimately, the 3320M served as a dependable workhorse in corporate fleets worldwide until it was superseded by Haswell in 2013, which brought massive battery life improvements.
Improvements over Previous Generation
- Higher graphics turbo (1200MHz vs 1300MHz)
- 22nm Tri-Gate process
- PCIe 3.0 support
Alternatives & Competitors
Should You Buy It?
Not Recommended for the right buyer
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.
