Despite being similar in the above ways, these processors have some stark differences. The i9 9900k performs hyper-threading on 16 threads while the i7 9700k executes the same process on eight threads. With all cores activated, the i9 9900k processor can run at a speed of up to 5GHz while the i7 9700k maxes out at 4.7GHz. The i9 chip implements dual-channel memory with 2MB L2 and 16MB L3 cache memories while the i7 processor achieves the same using a 1.5MB L2 and 12MB L3 cache memories. The i9 9900k processor has a 95-watt TDP while the i7 9700k chip has a 140-watt TDP. Judging from this comparison, the i9 9900k is more potent than the i7 9700k processor.

Benefits of using 9th generation Coffee Lake processors

The i7 9700k and i9 9900k chips are both 9th generation Coffee Lake processors, and they provide the following advantages for you:

High-speed performance

This 9th generation Intel chips are both octa-core processors. This means that each chip has eight silicon cores to convert raw data into information. By having multiple cores, these processors make your computing experience very fast. They perform even quicker after being complemented with high capacity RAM chips and Graphical Processing Units (GPUs). With this type of processor in your laptop or desktop PC, you can complete tasks at a rapid pace and boost your productivity.

Energy efficiency

The i7 9700k and i9 9900k chips are designed to use minimal power for maximum output. They are also constructed using materials that dissipate heat rapidly. It prevents them from overheating and destroying other components or your motherboard. By operating with minimum electrical power, these 9th generation processors last longer and keep your computer running safely by minimizing the risk of short circuits, melting or fire. In these ways, the 9th generation processors are considered innovative and energy-efficient.

Increased compatibility

An exciting characteristic of 9th generation processors chips is that they are compatible with different motherboard models. This is great for gamers who enjoy taking a Do It Yourself (DIY) approach to building their gaming rigs. Thanks to their flexibility and compatibility, these chips can be installed in purpose-built aftermarket motherboards. Installing an i7 or an i9 series processor in your gaming rig grants you maximum processing capability for intense gaming.

Overclock capability

The i7 and i9 series processors are very resilient because of their robust construction. This means that they can be overclocked using special software without the risk of malfunction. Overclocking involves the direction of high voltage through the chip to increase its speed. Ardent gamers can push 9th-generation chips to their limit without worrying about the risk of melting or incineration.

They are future-proof

The 9th generation chips were unveiled in late 2017 and 2018 and have powered the newest laptop models ever since. Users are delighted with their performance, and many are comfortable to keep using these chips for many years to come. As such, the i7 and i9 are future-proof chips. They can keep operating effectively in laptops and desktop PCs in the next five years without going obsolete.
