Pentium G3258 Details

The Intel Pentium G3258 stands out in its class not for raw power, but for its unlocked multiplier—a rare feature in a budget-oriented processor. Launched in June 2014 as part of Intel's Haswell lineup, this desktop CPU was designed for mainstream users seeking a balance of performance and affordability. While it may seem dated by today’s standards, its unlocked multiplier simplifies overclocking and makes it a compelling choice for budget builders and enthusiasts looking to squeeze more performance from a modest investment. As of March 2026, the G3258 remains a niche option, especially in systems where integrated graphics and cost efficiency are priorities.

Built on Intel's 22 nm process, the G3258 features a dual-core, dual-thread design with a base frequency of 3.2 GHz and a turbo boost up to 3.3 GHz. It operates on the FCLGA1150 socket, compatible with H81, B85, H87, Z87, H97, and Z97 chipsets, offering flexibility for older motherboards. The processor integrates 3 MB of L3 cache, with 61 KiB of L1 and 244 KiB of L2 cache per core, supporting DDR3-1333 memory in dual-channel mode with a maximum capacity of 32 GB. Despite its modest core count, the G3258 achieves a memory bandwidth of 21.3 GB/s and supports ECC memory, a feature uncommon in consumer-grade CPUs and valuable for stability in light server or workstation environments.

The integrated Intel HD Graphics (Haswell) delivers a base frequency of 350 MHz and can boost up to 1.1 GHz, supporting up to three displays and offering decent performance for light multimedia and casual gaming. With a TDP of 53 W, the G3258 strikes a balance between power efficiency and thermal management, making it suitable for small form factor builds. It supports a wide range of modern features, including AVX2, FMA3, AES-NI, and virtualization technologies like VT-x and VT-d, ensuring compatibility with contemporary software and operating systems.

In benchmark testing, the G3258 scores 4,612 overall, placing it at #1,182 among 2,060 processors, with a single-core score of 4,694 (#1,151) and a multicore score of 4,488 (#1,247). These results indicate that while the processor holds its own in single-threaded workloads—especially given its high base clock and unlocked multiplier—it lags behind modern CPUs in multi-threaded performance due to its limited core count. It outperforms some older processors like the Core i3-8130U and Xeon E5620 but falls short of contemporaries such as the Core i5-2500K and Ryzen 3 2200U.

In conclusion, the Pentium G3258 is best suited for budget desktops, light office computing, and entry-level multimedia tasks. Its unlocked multiplier makes it a unique choice in the low-end market, appealing to users who want to overclock without investing in a high-end CPU. While it cannot compete with today’s top-tier processors in either single-core or multicore performance, its affordability and flexibility ensure it remains relevant in niche builds and retro computing scenarios.
