Core i7-875K Details

As of March 2026, the Intel Core i7-875K remains a notable example of early 2010s desktop performance, particularly for its era. Despite being over a decade old, it continues to hold a competitive edge in certain benchmarks, ranking #1345 overall with a score of 4439. This places it just behind mainstream processors like the Core i5-660 and A10-5700, but ahead of several modern low-power and embedded chips, demonstrating its enduring relevance in synthetic testing environments.

The processor is built on Intel's Lynnfield architecture, fabricated on a 45 nm process node, and operates at a base frequency of 2.933 GHz, with a turbo boost up to 3.6 GHz. It features four cores and eight threads thanks to Intel Hyper-Threading, allowing it to efficiently handle multithreaded workloads. The die contains 774 million transistors and spans 296 mm², reflecting the design priorities of its time—performance with moderate power consumption.

Memory support includes DDR3 with a dual-channel interface and a maximum rated speed of 1333 MT/s, though enthusiasts can push beyond this with overclocking. The memory bandwidth caps at 21.3 GB/s, which was respectable for its generation but now lags behind modern standards. The Core i7-875K uses the Socket 1156 platform and is packaged in FC-LGA8, requiring an H55, H57, or P55 chipset for full functionality.

Key specifications include 8 MB of L3 cache, 0.061 MiB of L1 cache, and 0.244 MiB of L2 cache, ensuring fast access to frequently used data. It supports a wide range of Intel technologies, including VT-x and VT-d for virtualization, TXT for trusted execution, and various SSE extensions up to SSE4.2. However, it lacks integrated graphics, meaning a discrete GPU is mandatory for visual output.

In terms of performance, the Core i7-875K achieves a single-core score of 4404, placing it at #1385, and a multicore score of 4491, ranking #1243. This indicates a balanced performance profile, though its multicore advantage is modest compared to modern processors. While it is outpaced by current-generation CPUs in both single- and multicore workloads, its performance is still comparable to some mid-tier modern chips, such as the Pentium J4205 and Core M 5Y10.

With a TDP of 95 W, the Core i7-875K demands adequate cooling, especially under sustained load or during overclocking, which is made easier due to its unlocked multiplier. Its PCI-Express Gen 2 interface supports up to 16 lanes directly from the CPU, enabling decent expansion capabilities for the time.

In conclusion, the Core i7-875K is best suited for legacy systems, retro builds, or budget retro gaming setups where integrated graphics are not required and modern performance is not the primary concern. It remains a solid choice for enthusiasts looking to maintain older platforms or for those seeking a cost-effective upgrade path in older hardware ecosystems.
