Introduction: The King of Gaming, 3D V-Cache AMD’s 3D V-Cache technology has been hailed as the “king of gaming performance” since its initial release. This technology, which vertically stacks L3 cache on top of the CPU die, expanding it from 384MB to up to 1,152MB, is precisely optimized for the random data access patterns prevalent in gaming. The Ryzen 9 9950X3D achieves a 54% FPS improvement in Baldur’s Gate 3 and a 37% improvement in Starfield compared to the standard 9950X. It also offers a 15% gaming performance boost over its predecessor, the 7950X3D. This is not merely a “slightly faster” improvement but a generational leap. ...

Conclusion: Disruptive Changes Created by UALink and OpenAI, and Cisco’s Leap Forward OpenAI’s expanded strategic investments and the growing market influence of the UALink consortium provide long-term growth momentum for Cisco’s data center business. OpenAI’s transition to a ‘Public Benefit Corporation (PBC)’ and the announcement of a large-scale infrastructure investment of approximately $1.4 trillion are leading to an explosive increase in AI workloads. As UALink, an 'open connectivity standard,' becomes mainstream in the evolution of AI infrastructure, network infrastructure flexibility and scalability are emerging as top priorities. With essential connectivity, security, and optimized network architecture becoming indispensable, Cisco is expected to benefit from both competition and partnerships. Background: OpenAI, UALink, and Changes in the Market Environment 1. OpenAI’s PBC Transition and $1.4 Trillion Infrastructure Investment Plan In October 2025, OpenAI transitioned from its non-profit parent to a ‘Public Benefit Corporation (PBC)’ that combines public benefit and profit, actively pursuing new investments and data center expansion. CEO Sam Altman unveiled a large-scale infrastructure investment plan of approximately $1.4 trillion, which corresponds to about 30 gigawatts (GW) of data center capacity. This scale, capable of supplying about 7.5 million U.S. households, signifies an evolution beyond a mere software company to an 'AI infrastructure utility.' ...

Cover Image Source: ADATA - The Future Trend of DDR5 Memory: A Comprehensive Analysis of UDIMM, RDIMM, and CUDIMM 10,000MHz DDR5 CUDIMM is a next-generation memory technology that dramatically enhances integrated graphics and on-device AI performance through a memory bandwidth revolution. It offers an approximate 78% performance improvement over conventional DDR5-5600 and, when combined with a Mixture of Experts (MoE) architecture, can significantly boost CPU offloading efficiency. What is CUDIMM? CUDIMM (Clocked Unbuffered Dual In-line Memory Module) is a next-generation memory technology that integrates a CKD (Clock Driver) chip into a DDR5 memory module. In conventional UDIMM (Unbuffered DIMM), the CPU’s memory controller directly sends clock signals to the memory chips. However, beyond 8,000MT/s, stability degrades due to clock jitter and signal attenuation issues. ...

Introduction: The ‘Hidden Value’ of Linux—The Only Alternative for Unsupported PCs, Environmentalism, and More In the previous two parts, we reached the practical conclusion that ‘Windows is more practical and cheaper’ in a modern desktop environment. However, this conclusion only holds true for new hardware. In areas where Windows falls short—older PCs/laptops, hardware not supported by Windows 11, end-of-life devices, and environmental responsibility—Linux offers an overwhelming and compelling alternative. It’s here, in the realm of sustainability and hardware longevity, that Linux truly shines. ...

Introduction: Between the Illusion and Reality of an “Easy Linux” Watching a Linux installation video on YouTube can make it seem like anyone can effortlessly jump to a Linux desktop. “Just a few clicks, plug in a USB, and follow the setup wizard!” But the reality is not so simple. Real-world testimonials from users who have settled into Linux after switching from Windows are filled with stories of troubleshooting right after installation: resetting the bootloader (GRub), partition errors, unrecognized network and graphics drivers, and input method/font issues. This is especially true for users in the CJK (Chinese, Japanese, Korean) character set, who face additional hurdles. ...

Introduction: The Pitfall of “Free” and Calculating the Real Cost Many people think, “Linux is free, so it must be cheaper than Windows,” when building a new PC or choosing an OS. It’s true that downloading an official Linux ISO costs nothing, while a retail copy of Windows 11 Home has a price tag of over $139. However, when you plan to actually use a desktop PC for work, daily tasks, school, or at home and switch from Windows to Linux, there are “hidden costs” to consider. This article will comprehensively analyze the actual transition costs for both Windows and Linux, and demonstrate with numbers why Linux often ends up costing more in terms of time and money. ...

Recently, the market landscape of the artificial intelligence (AI) industry can be described as a history of one company’s monopoly and the challenges against it. While Nvidia established itself as the exclusive “high-speed data highway” of the AI era, UALink (Ultra Accelerator Link) technology, created through the collaboration of major IT companies including AMD, is gradually gaining prominence. In the second half of 2025, a large-scale investment from OpenAI is transforming this technology from a simple open standard into the seed of an ‘industrial transformation.’ Today, we will delve deep into what UALink technology is, why it has been difficult to break Nvidia’s monopoly until now, and why OpenAI’s move is a signal that will shake the market. ...
