The processor features 4 cores and 8 threads, which is standard for modern entry-level solutions. The Zen 3 architecture provides a significant IPC (instructions per clock) improvement over the previous generation, positively impacting the system's overall responsiveness.

• Base frequency: 4.0 GHz.
• Maximum Turbo frequency: up to 4.2 GHz.
• Cache: The configuration includes 64 KB of L1 and 512 KB of L2 cache per core, along with a total L3 cache of 8 MB. Efficient cache management is one of Zen 3's strong points.

Integrated Radeon Graphics
A key feature of the "G series" is the presence of a GPU on the same die as the CPU. The Ryzen 3 5305G utilizes an iGPU based on the updated Vega architecture.

• Execution units (EUs): 6.
• Maximum dynamic frequency: 1700 MHz.
• Note: This integrated graphics solution is not intended for running the latest AAA games on high settings, but it is sufficient for everyday tasks, 4K video playback, office applications, and less demanding esports titles.

Power Consumption and Overclocking
The nominal thermal design power (TDP) of the processor is 65 W. An important feature is the unlocked multiplier, which theoretically allows for overclocking both the CPU and the GPU. However, the real potential depends on the specific motherboard and cooling system.

2. Compatible Motherboards: Choosing on the AM4 Platform

The Ryzen 3 5305G uses the well-known and widely used AM4 socket. This provides access to a vast array of motherboards, but there are important nuances.

Key Compatibility Points:

• Chipsets: The processor is officially compatible with motherboards based on the A520, B550, X570 chipsets, as well as older B450 and X470 models. BIOS/UEFI updates may be required for 400 series motherboards.
• PCIe Support: The CPU supports PCIe 3.0 standard. This is important to consider when selecting a graphics card or high-speed NVMe storage. Motherboards with B550 and X570 chipsets support PCIe 4.0, but the lines from the processor will operate in 3.0 mode.
• Selection Recommendations: There is no need to buy a top-tier X570 board for this CPU. The ideal choice is a budget model based on the A520 or B450/B550 chipsets. Choosing a B550 motherboard gives you a more advanced power subsystem and additional features (such as more USB and SATA ports) for potential future upgrades. Always check the CPU Support List on the motherboard manufacturer’s website and ensure BIOS firmware is up to date.

3. Supported RAM

The processor has a dual-channel memory controller and officially supports DDR4 standard.

• Maximum frequency: DDR4-3200 is the rated frequency that guarantees stable operation.
• Bandwidth: Up to 51.2 GB/s in dual-channel mode.
• ECC Support: Absent, which is typical for the consumer segment of Ryzen 3.
• Recommendations: To unlock performance, especially for the integrated Radeon graphics, operating in dual-channel mode is critical. Install two memory modules (e.g., 2x8 GB). It is advisable to choose kits with low timings (CL16 or CL14 for 3200 MHz) since iGPU performance directly depends on the speed of the RAM, which acts as video memory.

4. Power Supply Recommendations

With a nominal TDP of 65 W, the Ryzen 3 5305G is a very power-efficient processor.

• For systems with integrated graphics: Even considering the motherboard, storage drives, and peripherals, a quality power supply with 400-450 W is sufficient. This leaves headroom for the future addition of a low to mid-range discrete graphics card.
• For systems with a discrete graphics card: The power supply rating should be based on the requirements of the graphics card. Pairing with models like the NVIDIA GeForce GTX 1650 or AMD Radeon RX 6400 will require a 450-500 W PSU from a reputable brand (Seasonic, Corsair, be quiet!, Cooler Master).
• Note: The quality of the power supply is more important than its maximum wattage. It is recommended to choose models with 80 PLUS Bronze certification or higher.
