Intel Core i3-390M Details

Ranked #1403 of 2060 in overall performance, the Intel Core i3-390M sits in the lower tier of modern CPU benchmarks as of March 2026. While it once served as a mainstream mobile processor, its 2010 release places it well beyond current relevance, making it a relic in today's computing landscape. Despite its age, the chip retains value in legacy systems and embedded applications where power efficiency and basic processing are sufficient.

The Core i3-390M is built on Intel's Westmere microarchitecture, fabricated on a 32 nm process, and features two cores with four threads thanks to Intel's Simultaneous Multithreading (SMT) technology. It runs at a base frequency of 2.67 GHz, with a turbo boost capability up to 2.67 GHz, supported by a 2500 MT/s DMI 1.0 bus. The processor includes 3 MiB of L3 cache, 0.5 MiB of L2 cache, and 0.125 MiB of L1 cache, with 64-bit x86-64 instruction set support and a 35 W TDP. It uses a dual-channel DDR3-1066 memory interface with a maximum capacity of 8 GB and a peak memory bandwidth of 15.88 GiB/s.

Integrated into the chip is Intel's HD Graphics (Ironlake) GPU, which operates at 500 MHz with a burst frequency of 667 MHz and features 12 execution units. It supports up to two displays and provides basic graphics performance suitable for office tasks and low-demand multimedia. The processor supports a wide range of instruction sets, including SSE4.1, SSE4.2, AVX, AES-NI, and virtualization technologies such as VT-x and EPT, making it capable of running older virtualized environments.

In terms of performance, the i3-390M scores 4399 overall, with a single-core score of 4137 and a multicore score of 4793. Its multicore performance ranks #849, indicating that while it scales moderately under multi-threaded workloads, its single-core performance lags behind contemporary CPUs, ranking #1643. This disparity suggests that the processor is more effective in tasks that leverage parallelism rather than highly optimized single-threaded applications.

Compared to modern CPUs, the Core i3-390M is outperformed by nearly every processor in the top 50 lists, with even entry-level modern chips like the Ryzen 3 PRO 1200 or Core i3-7350K surpassing it in both single- and multicore performance. However, it competes closely with older mobile processors like the Core i3-2350M and Pentium G645, indicating it holds its own in its original market segment.

In conclusion, the Intel Core i3-390M is best suited for basic computing tasks in older laptops or as a replacement in low-power systems. While it lacks the performance and efficiency of modern processors, its integrated graphics and power efficiency make it a viable option for legacy environments. As of March 2026, it remains a testament to Intel’s mobile architecture from a bygone era, offering modest performance for non-demanding applications.
