Unboxing the Intel Core i5-12600K processor

Just like all of Intel’s 12th generation processors, the Intel Core i5-12600K is packaged inside a small blue cardboard box. Its design is simple and only tells you what processor you bought. There aren’t many technical specifications listed, except for the fact that the CPU is unlocked and that it uses the LGA1700 socket.

The packaging used for Intel Core i5-12600K

The back of the box is just as simple as the front, but it has a cutout that exposes the actual Intel Core i5-12600K processor. Inside the package, there’s only the processor and a small booklet that contains the installation manual and warranty details.

Unboxing the Intel Core i5-12600K processor is quick, as the package contains only the essentials. Unfortunately, the company doesn’t bundle a cooler with this CPU.

Hardware specifications

The Core i5-12600K is Intel’s mid-range option from the Alder Lake family of desktop processors. Its recommended price at launch is 289 ~ 299 USD, although that’s not the one we’ve seen in stores, where it’s listed for about 20 USD more. If you choose to spend your money on the Intel Core i5-12600K, you will get ten cores, 16 threads, 20 MB of Intel Smart Cache, and an integrated Intel UHD Graphics 770 chip.

A look at the Intel Core i5-12600K

As it’s built on the Alder Lake architecture, the processor’s cores are not all the same, and some are faster than others. Out of the ten cores, six are performance cores (also named P-cores) that run at a base clock of 3.7 GHz and turbo boost to 4.9 GHz. The other four cores are efficiency cores (or E-cores) that run at a standard frequency of 2.8 GHz and can reach a maximum speed of 3.6 GHz.

The P-cores handle the most demanding tasks, while the E-cores handle the less challenging tasks. Obviously, the performance cores are the ones that do the heavy-lifting in games and taxing applications. Another essential difference between the two sets of cores on 12th generation Intel processors is that the performance cores come with HyperThreading, while efficiency cores don’t. That leads to the unconventional number of threads. On the Intel Core i5-12600K processor that we’re testing today, we get 16 threads because it has 6 P-cores with 2 threads each (so 12 threads total), plus another 4 E-cores each with a single thread.

The underside of the Intel Core i5-12600K

The downside, so to speak, is that Intel’s Alder Lake processors need Windows 11 to run at their fullest. So while the Intel Core i5-12600K will run nicely on Windows 10 or Linux, for example, you’ll only get its real power in Windows 11 because, right now, it’s the only operating system that knows how to manage its different (performance and efficiency) cores. For more details, read Windows 11 vs. Windows 10 on 12th Gen Intel Core processors.

In terms of memory, the Intel Core i5-12600K supports up to 128 GB of either DDR4 or DDR5 RAM. You’ll have to choose the right motherboard before you buy the RAM because there are no mainboards on the market that can fit both memory types.

Moving on to PCI Express support, you have to know that the Intel Core i5-12600K supports both revisions 5.0 and 4.0. It has 20 PCIe lanes which can be split between the graphics card (x16) and the NVMe solid-state drive (x4). Alternatively, they could also be used in a configuration of two x8 components plus one x4.

Finally, a few words about power consumption: Intel abandoned the use of the standard TDP (Thermal Design Power) measurements for its 12th Gen processors, instead providing details about the Processor Base Power and Maximum Turbo Power values. PBP (Processor Base Power) specifies the amount of electrical energy required by the CPU in normal circumstances, while MTP (Maximum Turbo Power) specifies the maximum power requirements of the CPU when running at its highest turbo speed. In the case of Intel Core i5-12600K, the PBP is 125 Watts, and the MTP is 150 Watts.

Intel’s Core i5-12600K has excellent specs and an original architecture that make it a strong competitor in the mid-range desktop processors segment. Its maximum turbo speed is just shy of 5 GHz (4.9 GHz), which makes us believe that it’s a great CPU for gaming. Now let’s see what the benchmarks tell us:

Performance in benchmarks and games

We tested the Intel Core i5-12600K processor on a PC with the following hardware and software:

To get a clearer idea about the performance offered by the Intel Core i5-12600K, we compared it with its more powerful sibling, Intel Core i7-12700K (up to 5.0GHz, 12 cores, and 20 threads). However, one very important aspect is that, for the latter, we had a different hardware configuration when we reviewed it (ASUS ROG Maximus Z690 Extreme, Kingston FURY Beast DDR5 Memory, ASUS TUF Gaming GeForce RTX 3090). The numbers we got in benchmarks are influenced by the different hardware we used, but they should still be good indicators of the performance you get from the i5-12600K versus the i7-12700K.

We started by running CPU-Z to measure the processor's single-thread performance. We got an excellent score of 732 points, not far behind the 792 points achieved by the i7-12700K (which is 8.2% better).

We continued with a benchmark that evaluates the performance of processors in games: 3DMark CPU Profile. As most games today know how to multi-thread, we compared the all-core results. The Intel Core i5-12600K managed a score of 7962 points. It might look weak against the i7-12700K CPU, but it’s actually a very good result that describes this processor as an excellent choice for gaming.

NOTE: To avoid GPU bottlenecks as much as possible, for the game benchmarks, we used 1080p resolution and the lowest visual quality settings. However, as we mentioned at the beginning of this section, the results we got are with different hardware components, including the graphics unit. So, take everything from here on with a grain of salt.

In Shadow of the Tomb Raider, using the Intel Core i5-12600K, we measured a framerate of 191 fps. It's not very far behind what we got with the Intel Core i7-12700K.
