Core 2 Duo T5800 Details

As of March 2026, the Intel Core 2 Duo T5800 remains a relic of an earlier era in computing, representing the transition from dual-core desktop processors to more power-efficient mobile designs. Though released over a decade ago, it was once a cornerstone of Intel’s mobile lineup, targeting budget-conscious laptops and entry-level business systems. The T5800 was built on a 65 nm process and featured a 2.0 GHz clock speed with a 400 MHz front-side bus and a 35 W TDP, making it one of the more power-efficient dual-core CPUs of its time. Despite its age, the processor still holds relevance in niche environments where legacy system compatibility is critical.

The Core 2 Duo T5800 is based on Intel’s Core microarchitecture, an evolution of the NetBurst design that brought significant improvements in power efficiency and performance per watt. It features two cores and two threads, with no Hyper-Threading support. The processor operates at a base frequency of 2.0 GHz and includes a burst frequency of 1.86 GHz under Turbo Boost, though this capability is limited due to the older generation of Intel's dynamic frequency scaling technology. The integrated Intel HD Graphics GPU supports a maximum frequency of 792 MHz and can drive up to two displays simultaneously, a modest feature by today’s standards but sufficient for basic multimedia and office applications.

Memory support is limited to DDR3L 1333 MHz, with a maximum capacity of 8 GB across two channels, delivering a peak memory bandwidth of 21.32 GB/s. The CPU supports a variety of advanced instruction sets, including SSE, SSE2, SSE3, SSSE3, SSE4.1, and SSE4.2, along with AVX and AVX2, indicating strong multimedia and computational capabilities for its time. It also includes features such as Intel VT-x for virtualization, AES-NI for encryption, and EIST for power management. However, it lacks support for ECC memory, which restricts its use in enterprise environments.

In benchmark testing, the Core 2 Duo T5800 achieves an overall score of 4211, ranking #1660 out of 2060 processors. Its single-core performance is rated at 3981, placing it at #1779, while its multicore score stands at 4557, ranking #1150. While these scores are far behind modern processors—where top-tier CPUs exceed 8,000 in single-core and 12,000 in multicore—the T5800 still competes with some low-end mobile and desktop chips from the early 2010s. Notably, it is slightly slower than the Core 2 Duo E4600 and faster than the Pentium T4300, indicating its position as a mid-tier mobile CPU in its original market segment.

Today, the Core 2 Duo T5800 is best suited for legacy systems, educational use, or embedded applications where low power consumption and basic processing are more important than raw performance. Its lack of modern features such as support for DDR4, PCIe 4.0, or advanced security technologies limits its viability in contemporary computing environments. For users seeking a reliable, low-power dual-core processor for non-demanding tasks, the T5800 remains a viable, albeit outdated, option.
