In contrast, the i7 8700K is a desktop-grade processor based on the Coffee Lake architecture, boasting 6 physical cores and 12 logical cores.
Clock Speed and Turbo Boost
The Xeon E5 2689 has a base clock speed of 2.6 GHz, while the i7 8700K has a base clock speed of 3.7 GHz. Both processors support Intel Turbo Boost technology, which dynamically increases the clock speed of active cores under load. The Xeon E5 2689 can reach a maximum turbo boost speed of 3.6 GHz, while the i7 8700K can reach a maximum turbo boost speed of 4.7 GHz.
Cache Memory
The Xeon E5 2689 features a massive 45 MB of L3 cache, providing ample space for frequently accessed data. The i7 8700K, on the other hand, has a smaller 12 MB of L3 cache. A larger cache can significantly improve performance in applications that require frequent data access.
Memory Support
The Xeon E5 2689 supports up to 1 TB of DDR4 ECC memory, while the i7 8700K supports up to 64 GB of DDR4 non-ECC memory. ECC (Error-Correcting Code) memory helps detect and correct single-bit memory errors, making the Xeon E5 2689 more suitable for mission-critical applications.
PCIe Lanes
The Xeon E5 2689 provides 40 PCIe 3.0 lanes, while the i7 8700K provides 16 PCIe 3.0 lanes. PCIe (Peripheral Component Interconnect Express) lanes are used to connect expansion cards such as graphics cards, network cards, and storage devices. More PCIe lanes allow for greater flexibility and scalability.
Power Consumption and Thermal Output
The Xeon E5 2689 has a TDP (Thermal Design Power) of 145 watts, while the i7 8700K has a TDP of 95 watts. TDP represents the maximum amount of heat that the processor can generate under load. A higher TDP requires more robust cooling solutions.
Applications and Use Cases
The Xeon E5 2689 is an excellent choice for server-based applications that require high core counts, large cache sizes, and ECC memory support. These applications include virtualization, database management, and high-performance computing.
The i7 8700K is ideal for high-performance desktop applications, such as gaming, video editing, and 3D rendering. Its higher clock speeds and lower power consumption make it a great choice for enthusiasts and overclockers.
