Intel Core 5 120: A Comprehensive Overview of the Processor for a Reasonable PC Build

Introduction: The Return of Legendary Numbering

In 2023, Intel made an unexpected move by reintroducing digital numbering to its desktop CPU lineup, reminiscent of the early Core i5 days. The new Intel Core 5 120 (part of the Raptor Lake Refresh lineup) is positioned as an affordable yet powerful chip for modern tasks. This move sparked lively discussions within the community: is it a marketing gimmick or a genuinely new philosophy? In this article, we will delve into what this processor has to offer, its place in the market, and who will find it the ideal choice.

1. Key Specifications: Architecture and Performance

Codename and Process Technology The Core 5 120 processor is built on the updated Raptor Lake-R (Refresh) microarchitecture. This is an evolutionary development of the successful Raptor Lake, featuring firmware-level optimizations and potential improvements in the manufacturing process. The process technology used is Intel 7 (10 nm Enhanced SuperFin), which is well-established and demonstrates an excellent balance between performance and energy efficiency.

Core Configuration and Cache At the heart of the chip is a hybrid architecture, but this model utilizes only 6 performance cores (P-cores) Golden Cove. Energy-efficient cores (E-cores) are absent. Each physical core processes two threads thanks to Hyper-Threading, resulting in a total of 12 threads. This is a classic configuration for modern CPUs, well-suited for gaming and most productivity applications.

The level 3 cache (L3) is 18 MB, a solid figure for this segment. A large cache positively influences performance in gaming and tasks that involve active data exchange between cores.

Clock Speeds and Graphics The base clock speed of the performance cores is 2.5 GHz, but this is just the starting point. In Turbo Boost 2.0 mode, the processor can boost up to 4.5 GHz on a single core, and under multi-core loads, the frequency remains high due to an efficient power and cooling system. The integrated graphics core is the Intel UHD Graphics 730. This is basic graphics capable of driving multiple monitors, playing 4K videos, and handling office applications. It is not designed for gaming.

Performance Tests Results from synthetic tests help gauge the positioning of the processor. Geekbench 6 Single-Core: 2197 points is an excellent score that indicates high responsiveness in everyday tasks, browsing, and single-threaded games. Geekbench 6 Multi-Core: 9257 points showcases confident multi-threaded performance that can handle rendering, video encoding, and other parallel computing tasks.

Key Features

• Intel Thread Director Technology (relevant in hybrid models, but part of the technological stack): Although the Core 5 120 lacks E-cores, thread optimization in Windows 11 is present.
• PCIe 5.0 Support: Up to 16 lanes for graphics cards and 4 lanes for storage, providing future-proofing.
• Intel Application Optimization (APO): An exclusive technology for the 14th generation that dynamically optimizes thread distribution in supported games, potentially increasing FPS.
• Advanced Instructions: Support for AVX2, AVX-VNNI to accelerate AI tasks and data processing.

2. Compatible Motherboards: Choosing the Foundation

Socket The processor uses the LGA 1700 socket. This is a versatile platform that supports three generations of CPUs: Alder Lake (12th), Raptor Lake (13th), and Raptor Lake Refresh (14th). This offers tremendous flexibility in choosing a motherboard, including options on the secondary market.

Chipsets and Recommendations The optimal choices for the Core 5 120 are motherboards with B760 or H770 chipsets.

• B760 - the "golden mean." It offers full RAM overclocking (XMP 3.0), adequate PCIe 4.0 lanes for storage, and quality power delivery (VRM) for stable processor operation. Prices start at $110-130. For example, motherboards from ASUS TUF Gaming B760 or MSI B760 GAMING PLUS.
• H770 - provides slightly more PCIe lanes and USB/SATA ports. Suitable for those needing maximum expandability without paying extra for the high-end Z-series features. Prices range from $140-160.
• Z790 - excessive for the Core 5 120. Motherboards on this chipset support processor overclocking (which is locked in this model), have the most powerful VRM and maximum ports. It makes sense only if you plan to upgrade to a K-version processor in the future. Prices start at $200.
• H610 - budget option. Suitable for office or media center builds but has serious limitations: no RAM overclocking (often runs at 3200 MHz for DDR4), minimal ports, weak VRM. Price ranges from $70-90.

Practical Advice: For a balanced gaming or work build, choose the B760. Ensure that the selected model has modern M.2 connectors for NVMe drives and VRM cooling.

3. Supported Memory Types

The Intel Core 5 120 supports both DDR4 and DDR5 RAM. This is a key advantage of the LGA 1700 platform, allowing you to select the optimal solution based on price and performance.

• DDR4: A more budget-friendly option. For this processor, RAM with a frequency of 3200-3600 MHz and timings of CL16-18 would be optimal. This ensures high performance in games with minimal expenses. A 2x8 GB kit costs around $35-50.
• DDR5: The technology of the future with higher bandwidth. Recommended frequency is 5600-6000 MHz. In gaming, the difference from high-end DDR4 may be small (5-10% depending on the task), but in some productivity applications and using integrated graphics, the advantage is more noticeable. However, it is essential to keep in mind the latencies (timings). A 2x16 GB kit of DDR5-6000 costs between $90-120.

Practical Choice: If your budget is tight, DDR4 is a sensible and tried-and-true savings option. If you plan to use the PC for several years and intend to upgrade the graphics card, DDR5 will be a better investment, providing future-proofing. Ensure that the motherboard supports the selected memory type (motherboards are usually oriented toward one type).

4. Power Supply Recommendations

The processor's nominal TDP is stated at 65W. However, it is important to understand that this is the heat package under base load. In turbo boost mode (PL2), power consumption can briefly reach ~100-120W.

When choosing a power supply, consider not only the processor but also, primarily, the graphics card - the most power-hungry component.

• Build with a budget graphics card (e.g., NVIDIA RTX 3050/3060 or AMD RX 6600): A quality power supply with a capacity of 500-550W will be sufficient (e.g., Deepcool PF550 or Corsair CX550).
• Build with a mid-range graphics card (RTX 4060 Ti, RX 7700 XT) or for workstations: Recommended 600-650W (Seasonic Focus GX-650, be quiet! Pure Power 12 M 650W).
• For high-end graphics cards (RTX 4070 Ti and above): A power supply of 750W or more will be needed.

Critical Parameters When Choosing a Power Supply:

1. 80 PLUS Bronze, Gold, or higher certification. Ensures high efficiency and quality components.
2. Fully modular cables. Simplify assembly and improve airflow in the case.
3. Protections (OPP, OVP, UVP, SCP, OTP). Ensure the safety of components.
4. Quality Japanese capacitors. A direct indicator of reliability and longevity.

Do not skimp on the power supply. Saving $20 might result in losing the entire system.
