Introduction to the CPUs

In this comparison, we will examine the Intel Boxed Core I7-6700 and the Intel Core i7-9700K desktop processors. The I7-6700 is priced at $96.99, while the I7-9700K is significantly more expensive at $276.77. This price difference of about 186% raises questions about the performance enhancements and features offered by the newer model.

Performance Capabilities

The Intel Core i7-9700K boasts a higher maximum clock speed of up to 4.9 GHz compared to the I7-6700's base speed of 3.4 GHz. This means the I7-9700K is designed for better performance, especially in demanding applications like gaming and content creation. With 8 cores and 8 threads, the I7-9700K is built for multitasking and heavy workloads, whereas the I7-6700 also has 8 cores but lacks the same turbo speed, which can impact performance in demanding scenarios.

Compatibility with Motherboards

The I7-6700 is compatible with Intel's 100 Series Chipset, while the I7-9700K requires a motherboard based on Intel's 300 Series Chipset. This means that if you are upgrading from an older system, you may need to invest in a new motherboard for the I7-9700K. While the I7-6700 can be used with existing setups that utilize the LGA 1151 socket, the I7-9700K's compatibility is limited to newer technology, highlighting a potential extra cost for a full upgrade.

Memory Support

When it comes to memory support, the I7-9700K leads with a maximum capacity of 64 GB and supports DDR4 memory at 2666 MHz. In contrast, the I7-6700 supports both DDR4 and DDR3L memory types but does not achieve the same bandwidth capabilities. The ability to support higher memory frequencies and capacities makes the I7-9700K a more future-proof option, especially for users looking to maximize their system's performance.

Integrated Graphics

Both processors include integrated graphics, but the I7-9700K features Intel UHD Graphics 630, which is a step up from the graphics capabilities found in the I7-6700. This improvement allows for better graphical performance in everyday tasks and light gaming scenarios. However, for dedicated gaming, users may still prefer a dedicated GPU, especially given the performance differences between the two CPUs.

Cooling Solutions

The I7-6700 comes as a boxed processor, which typically includes a cooling solution suitable for its power requirements. In contrast, the I7-9700K does not include any cooling device in the box, meaning users will need to invest in an aftermarket cooler to ensure optimal performance. This additional cost should be considered when evaluating the overall expense of the I7-9700K, as it could add another $50 or more to your setup.

Price Comparison

The price difference between the two processors is significant, with the I7-6700 retailing for $96.99 and the I7-9700K at $276.77. This makes the I7-6700 about 65% cheaper than its counterpart. For budget-conscious buyers, the I7-6700 presents a compelling option, especially if they do not require the latest advancements in CPU technology. However, the additional features and performance of the I7-9700K may justify the higher price for users with specific needs.

Which should you buy?

In conclusion, the choice between the Intel Boxed Core I7-6700 and the Intel Core i7-9700K ultimately depends on your specific needs and budget. If you are looking for a cost-effective solution for basic computing tasks or older games, the I7-6700 is a solid choice. However, for those who require superior performance for gaming or intensive applications, the I7-9700K, despite its higher price tag, offers better speed, memory support, and future-proofing capabilities. Therefore, weigh your performance needs against your budget to make the best decision for your computing setup.
