To avoid that, you need to check the operating temperatures of both CPUs at high load and possible cooling solutions that you can administer.

  • Ryzen 7 3700x

Similar to most AMD processors, the Ryzen 7 3700x is also shipped with a dedicated stock cooler. It is a fact that AMD’s stock coolers are pretty good, and users generally don’t need to buy a third-party air or water cooler for their AMD-based system. That being said, the Ryzen 7 3700x processor from AMD goes up to 70°C temperature while operating at heavy loads.

Such temperatures can be easily maintained by the included stock cooler. Thus, you can get a decent performance out of your CPU without spending additional bucks on a third-party cooler. Although, we will highly recommend liquid cooling your system if you are planning to overclock your CPU and use it at a higher clock speed.

  • Intel i7 9700k

Recently, Intel has stopped shipping stock coolers with its overclocking compatible CPUs. This includes the K series processors, which also includes our next competitor, the Intel i7 9700k. As this CPU is dedicated to gamers, most users are going to overclock their system. And for that, most users prefer a liquid cooling system or an AIO cooling system. Thus, Intel has removed the stock coolers to save some manufacturing costs and bring down the prices of its CPUs.

Paired with a standard air cooler, the Intel i7 9700k already offers lower operation temperatures as compared with the Ryzen. Under heavy load, the Intel i7 9700k operates at around 65°C temperature levels. And while overclocked, you will notice around 75°C temperature levels for the same. Also, a decent 3rd party cooler like Noctua or CoolerMaster can bring down the temperatures even further while maintaining a quieter performance for your system.

Power Usage

The power usage of a CPU indirectly affects your whole system. The power drawn by a CPU is mentioned in the TDP unit, which stands for thermal design power. If the TDP of a CPU is higher, it will require more power from your power supply. This will reduce the efficiency of your power supply unit and make your computer struggle in heavy tasks, which increases the power draw for other hardware as well.

  • Ryzen 7 3700x

AMD was infamous in the past because of its power-hungry CPUs when it was designing 14 nm processors. But, AMD has managed to turn the whole thing around with the release of 3rd generation Ryzen series processors designed with the 7 nm architecture.

The Ryzen 7 3700x mentioned here has a TDP of only 65W, which is nearly 40% less than its competitors. Even with such low TDP, Ryzen is offering a higher thread count, which is admirable.

A lower TDP CPU like the Ryzen 7 3700x will bring down your system’s running cost a lot in the long run. As less power is being consumed, Ryzen 7 3700x is a perfect choice for budget-focused productivity systems.

  • Intel i7 9700k

While the power requirement for Ryzen CPUs has reduced by a lot in the past few years, the power requirement for Intel CPUs is, more or less, the same.

But, the higher power draw on the Intel i7 9700k helps to keep a balanced performance output for the processor even when it is working at its peak capacity. As the peak clock speed of Intel i7 9700k is around 5 GHz, you will find it stable while playing heavy games at face lesser FPS drops.


Overclocked systems offer much higher performance compared to the default clock system as the overclocked hardware, whether it is your CPU, GPU, or RAM, gets more work done in less amount of time. Ryzen CPUs have always been popular with the OC favored community in the past, But, the current generation of Intel processors also offers great OC capabilities.

  • Ryzen 7 3700x

The Ryzen 7 3700x already offers you a larger number of threads. Thus, you will not notice a lot of difference if you overclock your Ryzen CPU with decent air or even a water cooler. You can expect about a 100 MHz additional speed with the CPU after overclocking which offers a few percentages of gain in the performance

Ryzen CPUs is equipped with smart PBO technology. The PBO stands for precision boost overdrive that automatically overclocks the CPU when required and keeps the clock speeds at the standard level when not necessary. Thus, you can save yourself from the trouble of overclocking and resetting your CPU time after time.

  • Intel i7 9700k

Overclocking is yet another parameter where Intel i7 9700k seems to take a lead compared to the Ryzen 7 3700x.
