Intel Core i7-12700K vs AMD Ryzen 7 5800X Performance Review

  • A lot of questions appear when it comes to picking the best gaming CPU and GPU. This review compares Intel’s i7-12700K with AMD Ryzen 7 5800X, two high performing CPUs for today’s market.
  1. The “ryzen 7 vs i7” is a comparison of the performance of the AMD Ryzen 7 5800X and Intel Core i7-12700K. The review will include benchmarks, gaming tests, and a conclusion.

We’ve reached the Intel Core i7-12700K processor 12th Generation Intel Core Processor, which is part of the Core i7 family, in our evaluations of the new Intel Alder Lake CPU product stack. We will be able to evaluate the Intel Core i7-12700K and compare it against the AMD Ryzen 7 5800X thanks to MSI giving us with the Intel CPU and MSI motherboard. Because these two CPUs are in direct competition, what better way to compare them and perform a “versus” evaluation in benchmarks and gaming? This is a comparison of the Intel Core i7-12700K and AMD Ryzen 7 5800X processors.

On October 27th, 2021, Intel released their 12th Generation Intel Core Processors. We’ve only tested the Intel Core i5-12600K processor on DDR4 thus far, and then compared DDR4 vs. DDR5 performance with the 12600K. Check out our evaluation of the 12th Generation Processors to learn more about what makes the Alder Lake design unique. We also won’t go into DDR5 in this review; instead, see our DDR4 vs. DDR5 comparison to learn all there is to know about DDR5.

To refresh your memory, the Intel Core Processors of the 12th Generation are built on a hybrid design that includes both Performance Cores (P-Core) and Efficiency Cores (E-Core) components. Hyperthreading is supported by the P-Cores, but not by the E-Cores. The Intel SKUs for these CPUs are made up of a mix of these cores, as well as changes in cache and frequency. These new CPUs are capable of supporting both DDR5 and DDR4 memory. It depends on the motherboard, and PCI-Express 5.0 is supported by the new Intel Z690 chipset.

The Intel Core i7-12700K lies above the Core i5-12600K we tested in the product stack. This is a speedier CPU with more cores and a greater turbo power. There are a total of 12 cores in the Intel Core i7-12700K, including 8 performance cores and 4 efficiency cores. The 12600K has two extra performance cores, but the same amount of efficiency cores. Because Intel hyper threading is supported by Performance cores, the 12700K can handle a total of 20 threads. The eight Performance Cores produce 16 threads, while the four Efficiency Cores each deliver one thread, for a total of 20 threads. This is an increase of four threads over the 12600K.

In addition, the Intel Core i7-12700K has greater L2 and L3 cache than the Intel Core i7-12600K. It contains 12MB of L2 cache in total, which is 2.5MB more than the 12600K. The L3 Cache on the 12700K is 25MB, which is 5MB greater than the 12600K.

In terms of frequency, the Intel Core i7-12700K may eventually outperform the 12600K. To begin with, the 12700K supports Intel Turbo Boost Max Technology 3.0 at speeds up to 5GHz, but the 12600K does not. This might allow the 12700K to boost faster than the 12600K. The 12700K’s P-Core Max Turbo Frequency is up to 4.9GHz, the same as the 12600K, but with to the aforementioned Turbo Turbo Max Technology 3.0, it might boost to 5GHz under the appropriate conditions. The E-Core Max Turbo Frequency is up to 3.8GHz, which is faster than the E-Cores on the 12600K, which run at 3.6GHz. As a result, the E-Cores on the 12700K should be significantly quicker.

The Processor Base Power of the 12700K is 125W, exactly as the 12600K, however the Maximum Turbo Power is 190W, compared to 150W for the 12700K. As a result, you’ll need to use the higher 190W power level to reach that high 5GHz boost. The 12700K also has Intel UHD Graphics 770 and up to 128GB of DDR4 or DDR5 memory.


As previously said, MSI bought our CPU for us, so thank you to MSI for donating the hardware. Above you can see the iconic Intel packaging; ours is an i7-12700K S-spec SRL4N Socket LGA1700 Alder Lake-S 841 retail CPU with product code and batch number.

In terms of RCP Pricing (USK 1K), the 12700K costs $409 against $289 for the 12600K. According to internet prices, it has been offered for as little as $400 to as much as $450. The AMD Ryzen 7 5800X may be obtained for a bit less, although prices have fluctuated a lot and are now between $355 and $400. So, we’ll see whether the somewhat greater cost of the 12700K is justified.
