Manufacturing technology and platform
The manufacturing technology for the CPU cores is TSMC 4nm FinFET, while the I/O die uses TSMC 6nm FinFET technology. The total number of chiplets in the package is 3. The processor uses the CPU Socket AM5 and is compatible with A620, X670, B650E, and B850 chipsets. The technology for boosting CPU performance is Precision Boost 2.
Advanced features, overclocking and operating systems
The processor is unlocked for overclocking and supports AMD EXPO Memory Overclocking technology. It also offers Precision Boost Overdrive and Curve Optimizer Voltage Offsets for fine-tuning voltage. For advanced management and monitoring, AMD Ryzen Master support is available. The processor's instruction set is x86-64. Supported extensions include AES, MMX-plus, SHA, and SSSE3. Supported operating systems include Windows 11, Windows 10, RHEL x86, and Ubuntu x86.
Connectivity, expandability, cooling and operating conditions
The processor offers 4 native USB 3.2 Gen 2 ports and 1 native USB 2.0 port. It supports PCI Express version PCIe 5.0 with a total of 28 native lanes, 24 of which are usable. Additional usable PCIe lanes from the motherboard vary depending on the chipset; for example, the X870E provides 8x Gen4. NVMe support includes Boot, RAID0, RAID1, RAID5, and RAID10 modes. A cooler is not included with the processor. For optimal performance, a liquid cooler is recommended to effectively manage heat dissipation. The maximum operating temperature is 95°C.
Memory support and integrated graphics
The system memory type is DDR5, and the processor supports 2 memory channels. The maximum memory capacity is 256GB, and the supported subtype is UDIMM. ECC support is available but requires motherboard support. The processor includes the integrated AMD Radeon Graphics model. The graphics unit has 2 cores and operates at a frequency of 2200MHz. It also supports USB Type-C DisplayPort Alternate Mode for connecting a monitor.

Processor cores and threads
To a certain extent, processor cores function as separate processors, handling computing tasks independently of each other. 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, enabling it to handle sixteen processes at once.
Processor frequency
The operating frequency indicates the processor's speed. 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 under heavy load (Turbo Boost).
L2 and L3 cache
To work as fast as possible, a processor needs fast storage where it can save temporary data. This is what the on-chip L2 and L3 caches are for. While these memories are significantly smaller than RAM, they are also faster. L2 and L3 are the first storage areas the processor interacts with, and generally, the bigger the better.
Processor socket
Before you choose a new processor, you should know which 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 RAM. 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 at maximum load, while also suggesting its energy consumption. A lower TDP means the processor uses less energy and generates less heat, which is ideal for laptops or energy-efficient systems. Conversely, processors with a high TDP offer higher performance but require advanced cooling to prevent overheating.
Processor cooling
A processor, much like a graphics card, generates heat during operation that 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 sufficiently cool your processor's performance, get an external one. External CPU coolers come in various sizes and performance levels, and many support stylish RGB backlighting. You can get a classic air-cooled version or a modern liquid-cooled one.Specifications
