Overview of the Processors

The Intel® Core™ i5-11600K is a more advanced option compared to the Intel Boxed Core i7-6700, offering higher performance capabilities at a significantly higher price. Priced at C$390.63, the i5-11600K is designed for modern gaming and multitasking, while the i7-6700, available for C$141.44, presents a more budget-friendly choice with respectable performance for everyday tasks.

Performance and Speed

The Intel® Core™ i5-11600K boasts a maximum clock speed of up to 4.9 GHz, making it an adept processor for tasks requiring high computational power, such as gaming and content creation. In contrast, the Intel Boxed Core i7-6700 has a maximum speed of 4.00 GHz, which, while commendable, does not reach the peak performance offered by the i5-11600K. This difference of 0.9 GHz can translate to noticeable performance improvements in demanding applications for the i5-11600K.

Core Count and Threading

The i5-11600K features 6 cores, providing efficient multitasking capabilities, especially in modern applications that can utilize multiple threads. Meanwhile, the i7-6700 has 4 cores, limiting its multitasking performance relative to the i5-11600K. The additional cores in the i5-11600K can enhance overall system responsiveness and allow for better handling of concurrent processes, making it a more future-proof option for users looking to run multiple applications simultaneously.

Compatibility with Chipsets

The Intel® Core™ i5-11600K is compatible with Intel 500 series and select Intel 400 series chipset-based motherboards, allowing for more versatility in system upgrades. In comparison, the i7-6700 is designed to work with Intel 100 Series Chipset Motherboards. This difference in chipset compatibility means that users opting for the i5-11600K can choose from a wider range of modern motherboards, which may offer better features and support for newer technologies.

Memory Support

The i5-11600K supports Intel Optane Memory and PCIe Gen 4.0, enhancing data transfer speeds and system responsiveness. Conversely, the i7-6700 supports DDR4 and DDR3L memory but does not include Optane support or PCIe Gen 4.0 capabilities. The advanced memory and PCIe support in the i5-11600K can significantly improve the overall performance of a system, especially for users who intend to build a high-performance PC.

Thermal Solutions

The Intel® Core™ i5-11600K does not come with a thermal solution included, which means users will need to invest in an aftermarket cooler to ensure optimal thermal performance. On the other hand, the i7-6700 is boxed and typically includes a stock cooler. While this may initially seem like a benefit for the i7-6700, users of the i5-11600K often opt for high-performance cooling solutions to unlock the processor's full potential, which can be an additional expense to consider.

Price Comparison

The price difference between the two processors is considerable. The i5-11600K is priced at C$390.63, while the i7-6700 is significantly cheaper at C$141.44. This makes the i7-6700 an attractive option for budget-conscious consumers or those who do not require the latest in processing power. However, the investment in the i5-11600K may be justified for users seeking a processor that can handle more demanding tasks and provide better longevity in a rapidly evolving technology landscape.

Which should you buy?

Deciding between the Intel® Core™ i5-11600K and the Intel Boxed Core i7-6700 ultimately comes down to your specific needs and budget. If you are looking for superior performance, modern features, and the ability to handle demanding applications, the i5-11600K is the clear winner despite its higher price. However, if you are interested in a more budget-friendly option that still offers solid performance for everyday tasks, the i7-6700 remains a viable choice.
