AMD Ryzen7 3700X vs Intel Core i9-9900K: 8 cores with the same frequency

By  Adan Flannigan 2019-07-09 4818 0

The performance of AMD's third generation Ryzen should be taken into account in the evaluation. Therefore, we plan to measure interesting projects. Both the AMD Ryzen 7 3700X and the Intel i9-9900K are 8-core processors with 16 threads, but the standard frequencies are not the same, so the absolute performance is slightly different. What's gonna happen?

AMD Ryzen7 3700X vs Intel Core i9-9900K

Performance at the same frequency is one of the most important indicators of the pros and cons of architecture: in general, the stronger the performance at the same frequency, the greater the architectural advantage. Of course, the high frequency also represents the advantage of the architecture. Intel's advantage is that it can be operated relatively easily at 5 GHz. It is also a fact that AMD is difficult to break through 4.4 GHz due to cold air and water.

But today this frequency indicator will not be discussed for the time being. We try to bring the Ryzen 7 3700X and the i9-9900K to a frequency of 4 GHz. Let them fight together to see if Zen 2 is powerful or Core Coffe Lake is powerful.

Ryzen 7 3700X vs i9-9900K Parameter comparison


Ryzen 7 3700X





Process Node

7 nm





Clock speed



L3 cache












Ryzen 7 3700X uses TSMC's 7nm process, while Intel uses 14nm technology, which hasn't been heavily modified for many years.

The Ryzen 7 3700X's L3 cache is much larger, and the L3 cache performance is actually very high and it's worth looking forward to. In terms of frequency, the Intel Core architecture dominates, and for many years it has been the killer for gaming performance and single-core performance.

Also worth mentioning is the starting price, Ryzen 7 3700X from 2599, Intel i9-9900K from 4999. Both have a certain price reduction, but Ryzen 7 is much cheaper than i9.

Two processors, Intel core frequency off, AMD core acceleration off, PBO off, manual lock 40 times frequency, ie 4 GHz frequency, voltage auto, memory is also 3200 MHz, C14-14-14-34.

There are a total of 4 theoretical performance test projects, but what is unexpected is that 4 of them are all AMD victories. Although the lead is not large, it is basically able to complete the Zen 2 architecture.

3DMARK is able to relieve the physics of the CPU: In this test, the Ryzen 7 3700X is much stronger than the i9-9900K, which is about 13% ahead.

The difference in gaming performance between the two is not too big, but the Ryzen 7 3700X is slightly better. Given the CPU's impact on the game, there is no large graphics card, so the superiority of Zen 2 can still be expressed.

Ryzen 7 3700X vs i9-9900K: current consumption temperature test

 Power consumption and temperature test

Power consumption and temperature test: After all of the above elements were abused by AMD, this element finally gave Intel i9-9900K a lost trust. After both sides have been downgraded to the same level, the Core i9-9900K has lower heat generation than AMD and lower power consumption.

Finally the same frequency test summary

By default, the i9-9900K can achieve the single-core score advantage of the i9-9900K CPU-Z from turbo to single-core 5.0GHz, full-core 4.7GHz, and after this round of low-frequency strike testing, the i9-9900K's single-core score advantage was surpassed by the Ryzen 7 3700X. However, after shutdown, the i9-9900K consumes more power than the AMD processor and has a lower temperature.

This test shows that the same performance of the Ryzen 7 3700X and the i9-9900K is better than that of the i9-9900K, meaning that the AMD Zen 2 architecture has the same frequency IPC performance. Stronger than the Intel Core Coffee Lake, with a good architectural advantage to force 7nm.

 comprehensive performance comparison

Finally, a comprehensive performance comparison of all performance projects, Ryzen 7 3700X 4GHz comprehensive performance than i9-9900K be 7.8% stronger.

This is of course only a comparison test of the blocking frequency. As for the silent test, you can look down.
