Celeron G1840T Details

The Intel Celeron G1840T represents a step down from its predecessors in the Haswell era, offering a modest upgrade in performance while maintaining the same foundational architecture. Released in May 2014, this processor is now over a decade old, placing it firmly in the category of legacy hardware. Despite its age, the G1840T still serves as a functional option for basic computing tasks, particularly in systems where cost and power efficiency are prioritized over high-end performance.

Built on Intel's Haswell microarchitecture and manufactured on a 22 nm process, the Celeron G1840T is designed for the desktop market and features a dual-core, dual-thread configuration. It operates at a base frequency of 2.5 GHz, with no turbo boost support, and includes 3 MB of L3 cache. The processor uses the Socket 1150 platform and supports DDR3 memory via a dual-channel interface. With a TDP of 54 W, it maintains reasonable power consumption for its class, though it lacks the modern efficiency improvements found in newer designs.

Integrated into the G1840T is Intel HD Graphics (Haswell), which provides basic graphical performance suitable for light multimedia playback and casual use. While not capable of handling modern games or demanding applications, the GPU supports up to three displays and includes standard video decoding capabilities. The processor also supports a range of instruction sets, including AVX2, AES-NI, and SSE4.2, enabling efficient data processing and encryption tasks, though it does not support simultaneous multithreading.

In benchmark testing, the Celeron G1840T achieves an overall score of 4379, placing it at #1431 out of 2060 processors. Its single-core performance scores 4403, ranking #1389, while its multicore performance reaches 4343, placing it at #1604. These results indicate that the G1840T holds its own against some older dual-core processors but falls significantly behind modern CPUs. Notably, it performs similarly to the Pentium G840 and Celeron G1820TE, both of which are from the same generation, but trails behind more powerful processors like the A8-7500 and Athlon II X4 631.

As of March 2026, the Intel Celeron G1840T is best suited for entry-level desktops, light office use, and embedded systems where integrated graphics and low power consumption are priorities. It remains relevant in legacy environments but is no longer competitive in the modern computing landscape. For users seeking improved performance, upgrading to a more recent processor would be necessary to meet current software and multitasking demands.
