Intel Pentium G4620: A Budget Processor for Basic Tasks in 2025

Introduction

Even years after its release, the Intel Pentium G4620 remains a popular choice for budget PCs. This dual-core processor based on the Kaby Lake architecture (2017) remains relevant due to its low power consumption and support for Hyper-Threading. In this article, we will discuss who the CPU is suitable for in 2025, how to build a system based on it, and what pitfalls to consider.

1. Key Specifications

Architecture and Process Technology

The Pentium G4620 is built on a 14nm process technology and belongs to the Kaby Lake generation, the last Intel family before the transition to hybrid cores (followed by Coffee Lake).

- Cores and Threads: 2 cores / 4 threads thanks to Hyper-Threading.

- Frequency: Fixed base frequency of 3.7 GHz (no turbo mode).

- Cache: L3 — 3 MB, L2 — 512 KB per core.

- TDP: 51W — can be easily cooled even with passive coolers.

Performance

Based on Geekbench 6 tests (2025):

- Single-threaded: 736 points — equivalent to Intel Core i5-7400.

- Multi-threaded: 1603 points — weaker than Ryzen 3 1200 (4 cores / ~2000 points).

Key Features:

- Support for Intel Virtualization for virtualization tasks.

- Integrated Intel HD Graphics 630 (basic video processing, no 4K 60 FPS).

- Compatibility with Windows 10/11 and Linux.

2. Compatible Motherboards

Socket and Chipsets

- Socket: LGA 1151 (version v2, not compatible with Coffee Lake motherboards!).

- Chipsets: H110, B250, H270, Z270.

Examples of Motherboards:

- ASUS Prime B250M-A (about $60-80 on the secondhand market in 2025).

- Gigabyte GA-H110M-S2H (from $40) — requires a BIOS update for Kaby Lake support.

Selection Features:

- Ensure that the motherboard’s BIOS is updated to the version supporting Kaby Lake.

- For overclocking (if available), a Z270 chipset is needed, but the G4620 does not support overclocking.

3. Supported Memory

- Types: DDR4-2400 (officially), DDR3L-1600 (on some boards).

- Maximum Capacity: Depends on the motherboard — typically up to 64 GB (but excessive for the G4620).

Recommendations:

- The optimal option is 8-16 GB DDR4-2400 (e.g., Kingston HyperX Fury, $25-50 for an 8 GB module).

- DDR5 and PCIe 4.0/5.0 not supported — this is a limitation of the platform.

4. Power Supply Recommendations

With a TDP of 51W, the processor has a modest impact on overall power consumption.

- Without a discrete graphics card: A power supply of 300-400W (Corsair CV450 — $45).

- With a graphics card (e.g., GTX 1650): A power supply of 450-500W (EVGA 500 BR — $55).

Important:

- Don’t skimp on the power supply! Cheap models (like Apevia) can damage components.

- For passive cooling, look for power supplies with a Zero RPM mode (e.g., be quiet! Pure Power 11 400W).

5. Pros and Cons

Pros:

- Price: New units (rare in 2025) — $50-70, used — $20-30.

- Energy Efficiency: Ideal for low-power builds (home servers, office PCs).

- Hyper-Threading: Better multi-threading vs. dual-core processors without HT (such as Pentium G4560).

Cons:

- 2 Cores: Modern games (Cyberpunk 2077, Starfield) require 4+ cores.

- Outdated Platform: No upgrade path to newer CPUs without changing the motherboard.

- Weak Graphics: HD 630 will not handle even Fortnite on low settings.

6. Use Scenarios

Office and Web Browsing

- Working with documents, browser (+20 tabs), Zoom conferences.

- Example: A PC based on G4620 + 8 GB DDR4 + 256 GB SSD — $150-200.

Multimedia

- Watching 1080p videos, streaming via Plex.

- For 4K HDR, an external graphics card is required (e.g., GT 1030).

Light Gaming

- Older titles: CS:GO, Dota 2 (60 FPS on low settings).

- Emulators: PlayStation 2, GameCube — handles them at medium settings.

7. Comparison with Competitors

AMD Athlon 3000G (2025 Price: $60-80)

- 2 cores / 4 threads, Vega 3 (graphics stronger than HD 630).

- Cons: Lower frequency (3.5 GHz), AM4 platform requires replacement for upgrade.

Intel Pentium Gold G5600

- 2 cores / 4 threads, 3.9 GHz, UHD Graphics 630.

- Price: $70-90. The performance difference with G4620 is up to 10%.

Recommendation:

If graphics are needed — go for the Athlon 3000G. For tasks requiring IPC (single-threaded performance) — choose the G4620.

8. Practical Assembly Tips

1. SSD is essential: Kingston A400 240GB ($30) will eliminate bottlenecks in everyday tasks.

2. Cooling: The stock cooler is sufficient, but for quiet operation, consider the Deepcool GAMMAXX 400 ($20).

3. Motherboard: Look for models with M.2 and USB 3.1 (e.g., ASRock B250M Pro4).

4. Upgrade: The best addition would be a GTX 1660-level graphics card (but the processor will become the bottleneck).

9. Final Verdict: Who is the Pentium G4620 Suitable For?

This processor is a good choice if:

- Budget is limited, and tasks are simple: office work, studying, HTPC.

- You need a quiet system (you can build a PC without fans).

- You plan to use old components (DDR4, motherboards from 2017-2019).

Alternative for 2025: If the budget allows $100-150, consider a used Intel Core i3-9100 (4 cores) or Ryzen 3 3100.

The Pentium G4620 is not for gamers or video editors, but as a "workhorse" for basic tasks, it is still relevant. The key is to understand its limitations clearly.
