AMD Ryzen 5 7400 Architecture

The AMD Ryzen 5 7400 processor is built on the Zen 4 (Raphael) core architecture with TSMC’s 5nm FinFET process using the AM5 platform. This processor is designed for users who are looking for a reliable processor. This processor features integrated AMD Radeon Graphics that allows designing a system without a dedicated graphics card. This is mostly practical for multimedia stations or office PCs where severe graphics requirements are not present. The AMD Ryzen 5 7400 processor provides full support for PCIe 5.0 for future connectivity expansions.

Architecture Components

The basic building blocks of the AMD Ryzen 5 7400 architecture include: Cores and Threads, Compute Die (CCD), I/O Die (IOD), Socket Type, memory, Integrated Graphics, PCI Express, Thermal Design Power, clock, memory controller, Instruction Sets, Compatible Chipsets, and software system.

Cores and Threads

The AMD Ryzen 5 7400 features 6 cores and 12 threads. A core is an independent physical hardware unit in the processor. Each core reads and executes program instructions on its own. A 6-core processor features 6 separate physical processing units. Threads in this processor are virtual paths used for software instructions. SMT allows each physical core to execute two hardware threads concurrently. AMD uses SMT (Simultaneous Multithreading) to divide every physical core into two threads

Compute Die or CCD

The CCD (Core Compute Die) in the AMD Ryzen 5 7400 architecture is the physical silicon chiplet that features the actual processing cores, a shared L3 cache, and their individual L2 caches. AMD uses chiplet architecture in place of designing a single, large part of silicon. The processor uses a chiplet-based design consisting of a CPU Compute Die (CCD) and an I/O Die (IOD).

I/O Die (IOD)

The I/O Die in the AMD Ryzen 5 7400 processor is a separate 122 mm² silicon chip, designed on a TSMC 6nm process. It handles system I/O operations, peripheral connections, and memory control. The I/O Die (IOD) acts as a central hub for memory and I/O connectivity. The I/O die manages key functions such as memory connectivity and PCIe/I/O interfaces between the processor and the rest of the system. Built on a TSMC 6nm manufacturing node, this I/O Die is physically divided from the 5nm CPU Compute Die that features the 6 Zen 4 cores.
