Processor core
The foundation of its computing performance is 64 cores with Zen 5 microarchitecture, operating at a base frequency of 3.2GHz. The processor supports Simultaneous Multithreading technology, providing a total of 128 computational threads. Under higher loads, the frequency automatically increases to up to 5.4GHz. A 64MB L2 cache and 256MB L3 cache ensure fast data access.
Platform and connectivity
The processor uses the AMD TR5 socket and works with WRX90, TRX50, and Pro 695 chipsets. It supports eight-channel DDR5 RAM with ECC support, ensuring high data throughput and reducing errors when working with large datasets. For connecting graphics cards, accelerators, and NVMe storage, 128 usable PCIe 5.0 lanes are available. This connectivity allows for system configurations suited for rendering and computationally intensive tasks.
Professional features and management
The AMD PRO technology suite includes security and remote management features designed for business environments. It contains, for example, AMD Memory Guard for RAM encryption. Advanced users can take advantage of the unlocked multiplier and technologies like AMD EXPO or Precision Boost Overdrive for manual adjustment of performance parameters and processor behaviour.

Processor cores and threads
To a certain extent, processor cores act as separate processors and can handle computing tasks independently of each other. This means that the more physical cores a processor has, the more tasks it can process simultaneously. Threads can be described as separate virtual cores, which all modern processors have. An eight-core processor typically has sixteen threads, meaning it can handle sixteen processes at once.
Processor frequency
The operating frequency indicates the speed of the processor. Generally, a processor with a higher frequency can execute instructions faster than one with a lower frequency. A higher frequency ensures snappier and faster responses in everyday computer use, such as launching applications, browsing the internet, or editing documents. It ranges from 1 to 5GHz. Some CPUs offer a short-term frequency increase (Turbo Boost) under high load.
L2 and L3 cache
For a processor to work as fast as possible, it needs fast storage where it can keep temporary data. This is what the L2 and L3 caches, located directly on the processor, are for. While these memories are significantly smaller than RAM, they are also faster. L2 and L3 are the first storage the processor works with, and generally, the bigger, the better.
Processor socket
Before you choose a new processor, you should know what hardware connector (socket) your motherboard has for the CPU. The processor and motherboard must have the same socket designation; this is the first step to a functional build. Another important factor is the type of operating memory. You should know what type of RAM you have.
TDP (Thermal Design Power)
TDP (Thermal Design Power) is a processor parameter that indicates the amount of heat it produces under maximum load, while also suggesting its energy consumption. A lower TDP means the processor consumes less power and generates less heat, which is ideal for laptops or energy-efficient systems. Conversely, processors with a high TDP have higher performance but require advanced cooling to prevent overheating.
Processor cooling
A processor, much like a graphics card, generates heat when performing, which needs to be dissipated to keep the processor itself cool. Some chip packages already include a cooler, but if you want to be absolutely sure you can handle the processor's heat output, you should get an external one. External CPU coolers come in various sizes and performance levels, and many support stylish RGB backlighting. You can get both classic air-cooled and modern liquid-cooled versions.Specifications
