Dimension comparison
Overview
When comparing the Intel Boxed Core I7-6700 and the Intel Core i7-8700K, the latter stands out with its advanced features and higher performance capabilities. The i7-6700 is priced at $96.99, while the i7-8700K comes in at $185.37, making it about 91% more expensive. The price difference reflects substantial upgrades in processing power and efficiency.
Performance
The Intel Core i7-8700K significantly outperforms the i7-6700 in terms of processing speed and capabilities. With six cores and a maximum turbo frequency of 4.7 GHz, the i7-8700K is designed for high-demand applications and gaming, offering 3.70 GHz base clock speeds. In contrast, the i7-6700 features a base clock speed of 3.40 GHz with four cores, which may be sufficient for everyday tasks but lags behind when it comes to multitasking and performance in demanding environments.
Graphics
When it comes to graphics capabilities, both processors support Intel UHD Graphics, but the i7-8700K offers a more integrated experience. It is compatible with Intel Optane Memory, enhancing its ability to manage and speed up data access, which is particularly beneficial for gaming and graphics-intensive applications. The i7-6700 supports a display resolution of up to 4096x2304, which is impressive, but lacks the advanced features found in the i7-8700K, limiting its performance in modern gaming scenarios.
Memory Support
The i7-8700K supports system RAM of type DDR4, which is faster and more efficient than the DDR3L support of the i7-6700. The i7-6700 can handle DDR4-1866/2133 and DDR3L-1333/1600 memory types, but as technology progresses, DDR4 becomes the standard for newer systems. This makes the i7-8700K a better choice for users looking to build or upgrade to a future-proof system that can handle newer memory standards effectively.
Compatibility
In terms of compatibility, the i7-6700 is compatible with LGA 1151 motherboards and Intel 100 Series Chipsets, while the i7-8700K requires motherboards based on the Intel 300 Series Chipsets. This means that if you are considering an upgrade to the i7-8700K, you might need to invest in a new motherboard as well, which adds to the overall cost. However, the enhanced performance and features of the i7-8700K may justify this additional expense.
Power Consumption
Looking at power consumption, the i7-8700K operates at a TDP (Thermal Design Power) of 95W, similar to the i7-6700, which suggests that both processors are designed to be power-efficient. However, given the higher performance output of the i7-8700K, users may find that it delivers a better performance-per-watt ratio, especially for demanding tasks such as gaming and heavy multitasking.
Use Cases
The Intel Boxed Core I7-6700 is a solid choice for users who primarily need a processor for basic computing tasks, such as web browsing, office applications, and light gaming. Its price point of $96.99 makes it a budget-friendly option. Conversely, the i7-8700K is tailor-made for gamers and professionals who require robust processing capabilities for tasks like video editing, 3D rendering, and high-performance gaming, justifying its higher price tag.
Which should you buy?
Ultimately, the decision between the Intel Boxed Core I7-6700 and the Intel Core i7-8700K depends on your specific needs and budget. If you are looking for a cost-effective solution for general computing, the i7-6700 at $96.99 is a reasonable choice. However, for those seeking superior performance and willing to invest more at $185.37, the i7-8700K is the clear winner, offering advanced features and capabilities that are well-suited for demanding applications and future-proofing your system.
