Processor

CPU Model CPU Model – an encoded designation of the processor’s specifications. Higher numbers indicate a more powerful chip. The final letter shows special features: for example, U stands for low power consumption, H for high-performance graphics.

AMD EPYC 9124

Cores Number of Cores — the number of physical processing units within a processor. A minimum of two cores can handle basic tasks, while more cores boost overall performance, enabling faster and smoother operation of applications and games.

Threads Number of threads — the maximum number of data streams a processor can handle simultaneously. A higher thread count allows the CPU to process resource-intensive applications faster and more smoothly.

Base frequency, GHz Base Frequency — the number of instructions a processor can execute per second under light workloads, without boosting its frequency or generating additional heat. A higher base frequency means faster task execution.

3.0

Max frequency, GHz Max Frequency — the highest clock speed a processor can reach under heavy computational loads, such as running resource-intensive software or AAA games. Higher frequencies result in increased power consumption.

3.7

Cache L3, MB Cache (MB) — the processor’s internal memory that speeds up the handling of frequently used data by reducing the need to access slower system RAM. Cache sizes can reach dozens of megabytes, and the larger the cache, the higher the overall performance.

Power, W Power — indicates the energy consumption, i.e., the amount of power required for the processor to operate.

RAM

RAM type Each new generation of RAM consumes less power, allowing for higher bandwidth and faster system performance. The most energy-efficient variants are labeled with the "LP" prefix, indicating Low Power memory—ideal for mobile and ultra-thin devices.

TruDDR5 4800 MHz

RAM, GB RAM Capacity — the amount of memory installed in the device. A larger capacity ensures smoother performance and faster response. For resource-intensive tasks, at least 8 GB of RAM is recommended.

Maximum RAM

6 ТБ

Memory slots Number of RAM Slots — determines the maximum amount of memory the device can support. A device can have up to 4 slots, either occupied or empty. Maximum performance is achieved when using a pair of modules: 2 × 8 GB outperforms a single 16 GB module.
