  • CPU Speed

    The speed at which the processor operates in everyday use.

    During the execution of demanding applications (e.g. games), the frequency may automatically increase up to the Maximum Processor Frequency.

  • Cores

    The natural individual processing units that the processor has. The more cores a processor has, the more efficient it is in running multiple applications simultaneously. For simple use, 4 cores are sufficient, while for gaming and video processing, at least 6 are recommended.

  • Socket

    The processor socket type.

    The motherboard we choose should have the same socket in order for the processor to "fit in".

  • Maximum CPU Speed

    The maximum processor frequency is the frequency that the processor can reach when executing demanding applications that use one core. Generally, when running demanding applications (e.g. games), the frequency can automatically increase up to the Maximum Processor Frequency depending on the number of cores in use. (the fewer cores are active, the closer they can operate to the maximum frequency)

  • Unlocked

    Ability to change the processor clock settings to achieve higher operating frequency (overclocking).

  • Cache Memory

    Cache is a very fast memory that acts as an intermediary between the processor and RAM. It stores data that is frequently useful to the processor for faster access.

    The CPU is a performance monster for just €220 (boxed version, 3-year warranty).
    It has 6 cores, which games love, with high clock speeds, and in every game I’ve tried at 1440p, I haven’t seen it go above 70% utilization.
    It’s only 3–6% slower than the 9700X, which costs €230 (tray, because the boxed 9700X costs €267), 4–11% faster than the 9600X (costs €177 tray and €244 boxed), and a satisfactory 11–18% behind the 7800X3D in single-core performance (€280 tray & €345 boxed).

    Now, though, its biggest advantages aren’t the 6 performance cores with 5.3GHz turbo boost, but the 12 cores running at a lower 4.2GHz that it has inside. If gaming takes up 1/3 of your day, or even less—1/4—and the rest is spent on video rendering tests, app design and testing, virtual machines, streaming, mockups and AutoCAD for your work campaigns, and all the other things that, if I mentioned them, would fill the entire 65-inch TV in your living room with examples in the comments, then THIS IS FOR YOU! The processor with 18 cores (6 P-cores + 12 E-cores) makes the above tasks seem insignificant (at least at entry to mid level). I’ve paired it with 2*16GB 6400MHz CL32, a 2TB PCIe 5.0 SSD for projects, a 1TB PCIe 4.0 SSD for Windows + applications, and a Gigabyte B860M Aorus Elite Ice Wi-Fi 6E, and while I play WoW forever, I can effortlessly and continuously do things in the background on the other monitor. For cooling, I’ve installed an Arctic Freezer 36 ARGB White, and it stays well under control, even below 78–82 degrees while gaming and working simultaneously.

    If you’re not mainly a gamer, I recommend it so you can also get your work done without problems alongside gaming while you wait for things to finish.
    If you only care about gaming, go for the 9700X.

    The downside of Intel is that we no longer have new CPUs for LGA1851, so in 5 years, when it “gets old,” you’ll move to a new platform. With AM5, on the other hand, you start with a 9600X, with 5% lower gaming performance, and then “bam,” in 2029 you put in a 10800X3D for €350 and move to another level. With LGA1851 250K Plus, the only upgrade is the 270K Plus, which is simply 5–10% better in games and just +33% in multi-core, heavy-load tasks.

    The closest in performance for the work tasks mentioned above is the 9950X (16-core). In some scenarios one is better, in others the other, BUT it costs €450 (211% more money), and the €€ matter a lot when, for €500, you can get a basic 32GB DDR5 RAM kit?
