Xeon E5345 Details

As of March 2026, the Intel Xeon E5345 remains a legacy processor from the early 2010s, designed for server and workstation environments. Built on a 65 nm process and based on the Core microarchitecture, this quad-core CPU operates at a base frequency of 2.33 GHz with a turbo frequency of 2.3 GHz, delivering a balanced performance profile for its time. Despite its age, the Xeon E5345 retains relevance in niche applications where legacy compatibility is essential, such as older server platforms or embedded systems utilizing LGA771 sockets.

The processor supports up to 8 GB of DDR3 800/1066 memory across two channels, with a maximum memory bandwidth of 17.1 GB/s. It features integrated Intel HD Graphics with a base frequency of 500 MHz and a burst frequency of 667 MHz, capable of driving two displays simultaneously. While the integrated GPU is limited by today’s standards, it provides basic visual output without requiring a discrete graphics card. The Xeon E5345 is also equipped with a 64-bit architecture and supports a range of advanced features including AES-NI, AVX2, SSE4.1/4.2, Hyper-Threading, and Intel VT-x and VT-d virtualization extensions.

In terms of benchmark performance, the Xeon E5345 scores 4,210 overall, placing it at #1665 out of 2060 processors in the PassMark ranking. Its single-core performance reaches a score of 4,049, ranking #1726, while its multicore score of 4,452 places it at #1318. These results reflect a processor that, while outdated, still competes with certain modern low-power and budget processors such as the Core i3-3225 and Pentium G3430, which share similar performance ceilings. However, it trails behind the majority of contemporary CPUs, particularly in single-threaded tasks, where even entry-level modern processors outperform it.

The Xeon E5345's TDP of 80 W indicates moderate power consumption, suitable for systems with adequate cooling and power supply. Its PCIe 2.0 support with up to 16 lanes enables connectivity to high-speed storage and expansion cards, though it lacks modern features like PCIe 4.0 or 5.0. Despite its limitations, the processor’s inclusion in Intel’s vPro and TXT platforms highlights its focus on enterprise security and manageability.

In conclusion, the Xeon E5345 is best suited for legacy environments where its compatibility with older server platforms is more valuable than raw performance. While it no longer competes with modern high-performance CPUs, its reliability and integrated features make it a viable option for non-demanding workloads in specialized settings. For users requiring modern computing capabilities, this processor is no longer recommended.
