Pentium G620 Details

Ranked #1411 in single-core performance and #1516 overall, the Intel Pentium G620 delivers modest computational power by modern standards, yet remains a testament to the efficiency of early Sandy Bridge architecture. Launched in May 2011, this dual-core desktop processor is now over a decade old, placing it firmly in the legacy category. Despite its age, the G620 still holds relevance for basic computing tasks, especially in systems where integrated graphics and low power consumption are priorities. Its 2.6 GHz base clock and 2.8 GHz turbo frequency, paired with a 65 W TDP, reflect a design focused on balanced performance and thermal efficiency for its time.

Built on Intel's 32 nm process and based on the Sandy Bridge microarchitecture, the G620 features 504 million transistors and a 131 mm² die size. It supports dual-channel DDR3 memory at up to 1066 MHz, with a maximum capacity of 32 GB and memory bandwidth of 17 GB/s. The processor uses the FCLGA1155 socket and includes 3 MB of L3 cache, with 0.061 MiB of L1 and 0.244 MiB of L2 cache per core. While it lacks simultaneous multithreading, the processor does support a range of modern instruction sets, including AVX, SSE4.1, SSE4.2, AES-NI, and Intel's virtualization technologies such as VT-x and VT-d.

Integrated into the G620 is the Intel HD Graphics (Sandy Bridge) GPU, which operates at a base frequency of 850 MHz and can boost up to 1100 MHz. This GPU supports up to two displays and provides sufficient graphical capability for light multimedia use and basic office applications. The processor's locked multiplier limits overclocking potential, a design choice common among Intel's Pentium lineup, which prioritized affordability over enthusiast performance.

In benchmark testing, the G620 achieves a single-core score of 4381, placing it just behind higher-end processors like the Core 2 Duo E8600 and the Pentium 2020M. Its multicore score of 4200 ranks it at #2010, outperforming older dual-core CPUs such as the Core 2 Duo T7300 but falling short of modern integrated solutions. The overall Passmark score of 4309 reflects a processor that, while outdated, still holds up in entry-level environments. In comparison to the top 50 processors in the current market, the G620 is significantly outpaced by contemporary offerings such as the Ryzen Threadripper PRO 9995WX and Core Ultra 9 285K, which exceed 9000 in overall performance.

As of March 2026, the Pentium G620 remains a viable option for legacy systems, light office computing, or as a replacement in low-cost builds where raw processing power is not a primary concern. Its low power draw and integrated graphics make it suitable for older desktops, network appliances, or embedded applications. While it is no longer competitive in performance-intensive scenarios, the G620 continues to serve as a reliable workhorse in environments where simplicity and energy efficiency are paramount.
