Core i7-3667U Details

As of March 2026, the Intel Core i7-3667U remains a relic of the early Ivy Bridge era, having been released in June 2012. Despite its age, it still holds a place in the broader performance hierarchy, particularly for legacy systems or low-power mobile platforms where its 17 W TDP provides efficient operation. The processor is built on a 22 nm process and features a dual-core design with Hyper-Threading, enabling four threads to be processed simultaneously. Base clock speed is set at 2.0 GHz, with a turbo frequency reaching up to 3.2 GHz, allowing it to handle modest workloads with reasonable responsiveness. The chip integrates Intel HD Graphics 4000, capable of driving up to three displays at a maximum frequency of 1.15 GHz, though its performance is limited by today's standards. It supports DDR3 memory up to 1600 MHz in a dual-channel configuration, with a maximum capacity of 32 GB and a peak memory bandwidth of 25.6 GB/s. Cache hierarchy includes 61 KiB of L1, 244 KiB of L2, and a substantial 3.8 MiB of L3 cache, contributing to its ability to manage data-intensive tasks efficiently for its time.

In terms of real-world performance, the Core i7-3667U achieves an overall Passmark score of 4556, placing it at #1228 out of 2060 processors in the database. Its single-core performance is slightly stronger, scoring 4626 and ranking #1199, while its multicore score of 4451 lands it at #1319. These results indicate that the processor is better suited for single-threaded applications, a trait that remains relevant in many productivity and office environments. However, its multicore performance lags behind modern CPUs, with only a narrow margin over older and lower-tier processors like the FX-4100 and Athlon X4 845. In comparison to top-tier CPUs, the Core i7-3667U is far behind leaders such as the Ryzen Threadripper PRO 9995WX (score: 9492) or the Core Ultra 9 285K (score: 8530), highlighting the significant advancements in CPU design over the past decade.

The processor supports a wide range of modern features despite its age, including Intel's AVX and AVX2 instruction sets, AES-NI encryption, and Intel Virtualization Technology (VT-x and VT-d), making it suitable for virtualization tasks. It also includes features like Enhanced SpeedStep (EIST) for power efficiency and Secure Key for enhanced security. However, the lack of support for newer technologies such as DDR4 or PCIe 4.0 limits its appeal in contemporary systems. The locked multiplier restricts overclocking, a common limitation for mobile processors of its generation. For users seeking a balance between performance and power efficiency in a lightweight notebook, the i7-3667U remains a functional, if outdated, option. Its primary value today lies in niche use cases such as retro computing, embedded systems, or low-demand office workloads where energy efficiency and compatibility outweigh raw performance.
