Core i7-2655LE Details

Ranked #1126 in single-core performance with a score of 4735, the Intel Core i7-2655LE stands out for its surprisingly strong individual thread performance despite being a processor from the Sandy Bridge generation. As of March 2026, this chip is over eight years old, yet it still holds its own in the single-threaded domain, placing just behind high-end modern mobile processors like the Core i5-2400 and ahead of many mainstream and embedded CPUs. Its single-core strength is particularly notable given its 25 W TDP and embedded market focus, making it a compelling option for compact systems requiring responsive performance.

The Core i7-2655LE is built on Intel's Sandy Bridge microarchitecture, fabricated on a 32 nm process, and features a dual-core design with four threads thanks to Hyper-Threading. It operates at a base frequency of 2.2 GHz and can boost up to 2.9 GHz on a single core, with a 2.5 GHz boost on two cores. The processor includes a 4 MiB L3 cache and 0.5 MiB of L2 cache, with 64-bit support and a 64-bit wide data path. It supports DDR3-1066 and DDR3-1333 memory, with a maximum capacity of 16 GB across two channels, delivering up to 19.87 GiB/s of memory bandwidth. This makes it suitable for light multitasking and basic productivity workloads.

Integrated into the chip is Intel's HD Graphics 3000 GPU, featuring 12 execution units and a maximum frequency of 1200 MHz, capable of driving two displays simultaneously. While not powerful by today’s standards, it provides adequate graphics performance for office applications, media playback, and light content creation. The processor supports a wide range of Intel technologies, including Intel Turbo Boost 2.0, Enhanced SpeedStep, VT-x, VT-d, and AES-NI, ensuring efficient performance and security. It also supports ECC memory and Intel vPro, enhancing reliability and manageability in professional environments.

In multicore performance, the Core i7-2655LE achieves a score of 4512, ranking #1203 overall, which is slightly behind the single-core performance. This indicates that while the chip scales well across multiple threads, its older architecture and low TDP limit its ability to compete with modern multi-core processors. It trails behind contemporary embedded and mobile CPUs but remains competitive with some early 2010s desktop chips like the Xeon W5590 and Phenom II X4 840. In overall system performance, it scores 4646, placing it at #1152, showing a balanced but not dominant performance profile.

Given its age and power efficiency, the Core i7-2655LE is best suited for embedded systems, industrial automation, or thin clients where long-term stability, low power consumption, and reliable single-threaded performance are more important than raw processing power. While it no longer competes with modern high-end processors, it remains a capable workhorse in niche markets where legacy compatibility and energy efficiency are priorities.
