Unboxing the Intel Core i7-12700K processor is a fast and straightforward experience. You get exactly what you pay for: the CPU and practically nothing else. Unfortunately, there’s no bundled cooler in the box, and you need to purchase one separately.

Hardware specifications

The Intel Core i7-12700K is a higher-end desktop processor from the “Alder Lake” family. It counts 12 cores and 20 threads and, at a recommended customer price of about 420 USD, it aims to threaten AMD’s Ryzen 9 5900X and Ryzen 7 5800X processors. What’s interesting about the new Alder Lake CPU family is that it’s a new kind of architecture that uses specialized cores for demanding (foreground) tasks while also having “more traditional” cores for background services.

The Intel Core i7-12700K desktop processor

On the Core i7-12700K, out of the twelve cores, eight are P-cores (performance cores), and four are E-cores (efficiency cores). The performance cores are the ones that, obviously, are designed to deliver top performance, while efficiency cores are less powerful and are used for background services. While the P-cores support HyperThreading, the 4 E-cores don’t, thus the odd 20 threads count: 8 P-cores x 2 threads plus 4 E-cores equals 20 total execution threads. 🙂 This hybrid architecture is interesting, to say the least, and promises to deliver better and more efficient processors, but in order to do so, it needs the help of software. And right now, the only operating system that knows how to target and use the different types of cores to maximize performance is Windows 11.

The pins on the Intel Core i7-12700K desktop CPU

The P-cores on the Intel Core i7-12700K run at a base clock of 3.6GHz and can turbo boost up to 5.0GHz. The E-cores run at a base frequency of 2.7GHz and achieve a maximum turbo speed of 3.8GHz. The total amount of Level 2 cache memory is 14MB, 1.25MB for each P-core, and 2MB shared between the E-cores. As for the Level 3 cache, the processor comes with 25MB, shared by all the cores.

Regarding RAM specs, the processor supports both DDR4 and DDR5 memory. However, it can work with only one type of RAM at a time. Compatible motherboards can have either DDR4 or DDR5 support but can’t work with both types of memory

Starting with the 12th generation of processors, Intel doesn’t officially use the standard TDP (Thermal Design Power) measurements. Instead, for each CPU, the company specifies the Processor Base Power and Maximum Turbo Power. The first one tells us how much electrical energy the processor is expected to use in regular circumstances, while the latter lets us know the maximum amount of power it can consume when it runs at full turbo speed. For the Intel Core i7-12700K, the base power is 125 Watts, while the maximum turbo power is officially 190 Watts. Check the benchmarks section of this review to see what to expect in real life.

Intel Core i7-12700K supports PCI Express 5.0 for the graphics card slot (out of 20 lanes, 16 go to the GPU) and PCI Express 4.0 for the NVMe solid-state drive connected to it (using the other 4 PCIe lanes remaining). Last but not least, you should also know that this processor works on the new LGA1700 socket, and the only motherboard chipset that supports Alder Lake processors right now is the Z690. Therefore, if you want a 12th Gen Intel Core processor, take into account that you’ll also have to spend some money on a new motherboard. Furthermore, as the holes for the CPU heatsink have a new configuration, you might also have to invest in a new cooler for the processor, or at least buy an upgrade kit for your current one, if its manufacturer releases any.

The Intel Core i7-12700K has impressive technical specifications. Using a new hybrid architecture, it promises to deliver top-notch performance and goes right against some of AMD’s best-selling CPUs for enthusiasts, namely the Ryzen 7 5800X and Ryzen 9 5900X.

Performance in benchmarks and games

We tested the Intel Core i7-12700K processor on a PC with the following hardware and software:

To get a clearer idea about the performance offered by the Intel Core i7-12700K, we compared it with an AMD Ryzen 9 5900X (Zen 3 architecture, 12 cores, 24 threads). For this one, we used the same hardware but with two exceptions. The motherboard was an ASUS ROG Crosshair VIII Hero (Wi-Fi) built for AMD processors, and the memory kit was a HyperX Predator DDR4 RGB Memory (2 x 8GB, 3200MHz), as this CPU (and motherboard) can’t use DDR5 RAM.

We started with running CPU-Z to benchmark the processor's single-thread performance. We got an impressive score of 792 points. The Ryzen 9 5900X is left behind, as the Core i7-12700K is faster by about 18%!

Intel Core i7-12700K benchmark results: CPU-Z Single Thread

In CPU-Z's Multi-Thread benchmark, the Intel Core i7-12700K managed a massive score of 9299 points. But, even if the AMD Ryzen 9 5900X has the same number of cores, it has 4 threads more, and it kind of shows. 🙂 It got a slightly better score - 9539 points - which makes it a bit faster than the Core i7-12700K, by 2.5%.

In Blender, which counts the rendering time of various scenes, the faster CPUs get lower results. We decided to render the bmw27 and classroom scenes, and the Intel Core i7-12700K required 6.9 minutes to finalize them. That's a tiny bit more time than the AMD Ryzen 9 5900X needed, which was 6.9 minutes. To conclude, it looks like the Core i7-12700K is just as good a choice for video editors as the Ryzen 5900X.

3DMark also has a benchmark especially designed to assess the performance of your processor. It can show how fast a CPU is when using only some of its cores as well as when using all of its cores. Taking into account that most games and demanding apps today can use as many processor cores as there are available on your PC, we compared the all-core results from this benchmark. The Intel Core i7-12700K and the AMD Ryzen 9 5900X had similarly high scores (10054 and 10450 points), but the Intel CPU still offered a tiny bit more performance (3.9%).

In the end, we also tested the temperatures reached by the Intel Core i7-12700K, and for that, we ran AIDA64's stability tests. The maximum temperature we witnessed was 81 degrees Celsius (178 degrees Fahrenheit). It's a lower temperature than we expected, and that's excellent, but, as you can see in the following screenshot, the AMD Ryzen 9 5900X was even cooler. 🙂

Intel Core i7-12700K temperatures

As for the maximum amount of power consumed by the Intel Core i7-12700K in demanding workloads, it looks like it can draw up to 159 Watts, which is about 12% more electricity than the AMD Ryzen 9 5900X requires.

Intel Core i7-12700K power consumption

Intel Core i7-12700K is one of the fastest desktop processors we’ve tested. Its 12 cores and 20 threads allow it to deliver outstanding performance in any situation. Furthermore, after comparing it with the more expensive AMD Ryzen 9 5900X, we believe it’s safe to say that the Intel Core i7-12700K is the new king of the gaming processors division.
