| Processor manufacturer The manufacturer that produced the processor. | AMD |
| Processor socket Mechanical component(s) that provides mechanical and electrical connections between a microprocessor and a printed circuit board (PCB). This allows the processor to be replaced without soldering. | Socket AM4 |
| Compatible processor series A processor which is compatible with this device, belongs to a 'series' which is part of 'family' e.g Celeron D, Celeron G, Celeron M, or, in some cases, is the same as 'family'. | AMD Ryzen™ 3, AMD Ryzen™ 5, AMD Ryzen™ 7, 3rd Generation AMD Ryzen™ 9, AMD Ryzen 9 5th Gen |
| Supported processor sockets The sockets (plugs) for processors that are supported (can be used) by the device. | Socket AM4 |
| Memory | |
| Supported memory types Types of memory which can be used with the product. | DDR4-SDRAM |
| Number of memory slots | 4 |
| Memory slots type A memory slot, also known as a memory socket or RAM slot, is what allows computer memory (RAM) to be inserted into the computer. Depending on the motherboard, there will usually be 2 to 4 memory slots (sometimes more on high-end motherboards). The most common types of RAM are SDRAM and DDR for desktop computers and SODIMM for laptop computers, each having various types and speeds. | DIMM |
| Memory channels | Dual-channel |
| ECC ECC means Error Correction Code, and it is memory that is able to detect and correct some memory errors without user intervention. |
 |
| Supported memory clock speeds Memory clock speed is the time it takes for a computer to complete basic operations. It refers to the computer's processing speed and is measured in hertz. It is however not such a reliable measure of a computer's speed as it doesn't take into account other factors like RAM and cache size. | 2133,2400,2666,2800,3000,3200,3333,3466,3600,3733,3866,4000,4133,4266,4400,4466,4600,4800 MHz |

| Graphics | |
| Parallel processing technology support Parallel processing technology is the simultaneous use of more than one CPU or processor core to execute a program or multiple computational threads. Ideally, parallel processing makes programs run faster because there are more engines (CPUs or Cores) running it. In practice, it is often difficult to divide a program in such a way that separate CPUs or cores can execute different portions without interfering with each other. Most computers have just one CPU, but some models have several, and multi-core processor chips are becoming the norm. There are even computers with thousands of CPUs. | Not supported |
| Maximum resolution The maximum number of pixels that can be displayed in the image. It is usually quoted as width × height,: for example, "1024 × 768" means the width is 1024 pixels and the height is 768 pixels. | 3840 x 2160 pixels |

USB 2.0 connectors are usually colored black. | 2 |
| USB 3.2 Gen 1 (3.1 Gen 1) connectors This is a connector (normally attached to a cable) for USB 3.0. USB 3.0 is the second major revision of the Universal Serial Bus (USB) standard for computer connectivity. First introduced in 2008, USB 3.0 adds a new transfer mode called "SuperSpeed," (distinguishable from USB 2.0 by either the blue colour of the port or the initials SS) capable of transferring data at up to 5Gbit/s—more than ten times as fast as the 480 Mbit/s top speed of USB 2.0. | 1 |
| Number of SATA III connectors Serial ATA (Advanced Technology Attachment) (SATA) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives and optical drives. SATA III (revision 3.x) interface, formally known as SATA 6Gb/s, is a third generation SATA interface running at 6.0Gb/s. The bandwidth throughput, which is supported by the interface, is up to 600MB/s. This interface is backwards compatible with SATA 3 Gb/s interface. | 4 |
