Xeon W3670 Details

Ranking #1135 of 2060 in overall performance, the Intel Xeon W3670 presents a surprisingly balanced profile for a processor launched in August 2010. While its 6-core, 12-thread configuration may seem modest by today's standards, it was a significant step forward in server and workstation computing at the time, particularly with its support for ECC memory and triple-channel DDR3. The processor operates at a base frequency of 3.2 GHz, with a turbo boost up to 3.466 GHz, and leverages Intel's Hyper-Threading technology to deliver effective parallel processing capabilities. Built on a 32 nm process using 1.17 billion transistors, the Xeon W3670 is a product of the Gulftown architecture, designed for high-performance workloads in professional environments.

The Xeon W3670 is packaged in an FC-LGA10 socket and requires a Socket 1366 motherboard, which was a standard for high-end Intel platforms during its era. It supports up to 128 GB of DDR3 memory, with a maximum bandwidth of 21.3 GB/s across its triple-channel memory interface. Despite its age, the processor supports a wide range of modern instruction sets, including AVX, AVX2, AES-NI, and Intel's virtualization extensions such as VT-x and VT-d, making it suitable for virtualized and data-intensive applications. The TDP of 130 W indicates a power-hungry design, necessitating robust cooling solutions, particularly in multi-socket configurations.

In benchmark testing, the Xeon W3670 achieves a single-core score of 4621, placing it at #1200 in the single-core rankings. Its multicore performance scores 4738, ranking it #919 in the multicore category, which suggests that while it is no longer competitive with modern processors, it holds its own in workloads that benefit from thread-level parallelism. The overall score of 4668 places it in the middle tier of processors, outperformed by contemporary CPUs like the Ryzen 7 9800X3D and Core Ultra 7 265K but still competitive with older models such as the Core i7-5600U and Xeon X5470.

Notably, the Xeon W3670 lacks integrated graphics, requiring a discrete GPU for visual output, which aligns with its server-oriented design. However, its extensive feature set—ranging from Intel's Turbo Boost 2.0 to Intel vPro and Trusted Execution Technology—makes it a versatile option for enterprise environments where security, virtualization, and reliability are paramount. While the processor is now considered obsolete in mainstream consumer and even many professional markets, its robust ECC support and multi-threaded performance continue to make it relevant in legacy systems and specialized workstations.

As of March 2026, the Xeon W3670 remains a testament to Intel's engineering in the early 2010s, serving as a bridge between the era of multi-core optimization and the modern age of high-efficiency, high-performance computing. Its primary use cases today are limited to retro computing, legacy server upgrades, and niche applications where its specific combination of core count, memory support, and virtualization features are still valuable.
