TrendForce: Nvidia's Blackwell platform products drive TSMC's CoWoS production capacity to increase by 150% this year
Apr 17, 2024 pm 08:00 PM
According to news from this site on April 17, TrendForce recently released a report, believing that demand for Nvidia's new Blackwell platform products is bullish, and is expected to drive TSMC's total CoWoS packaging production capacity to increase by more than 150% in 2024. NVIDIA Blackwell's new platform products include B-series GPUs and GB200 accelerator cards integrating NVIDIA's own GraceArm CPU. TrendForce confirms that the supply chain is currently very optimistic about GB200. It is estimated that shipments in 2025 are expected to exceed one million units, accounting for 40-50% of Nvidia's high-end GPUs. Nvidia plans to deliver products such as GB200 and B100 in the second half of the year, but upstream wafer packaging must further adopt more complex products.

JavaScript tutorial: How to get HTTP status code, specific code examples are required. Preface: In web development, data interaction with the server is often involved. When communicating with the server, we often need to obtain the returned HTTP status code to determine whether the operation is successful, and perform corresponding processing based on different status codes. This article will teach you how to use JavaScript to obtain HTTP status codes and provide some practical code examples. Using XMLHttpRequest
AMD 'Strix Halo” FP11 package size exposed: equivalent to Intel LGA1700, 60% larger than Phoenix
Jul 18, 2024 am 02:04 AM
This website reported on July 9 that the AMD Zen5 architecture "Strix" series processors will have two packaging solutions. The smaller StrixPoint will use the FP8 package, while the StrixHalo will use the FP11 package. Source: videocardz source @Olrak29_ The latest revelation is that StrixHalo’s FP11 package size is 37.5mm*45mm (1687 square millimeters), which is the same as the LGA-1700 package size of Intel’s AlderLake and RaptorLake CPUs. AMD’s latest Phoenix APU uses an FP8 packaging solution with a size of 25*40mm, which means that StrixHalo’s F

Introduction to the method of obtaining HTTP status code in JavaScript: In front-end development, we often need to deal with the interaction with the back-end interface, and HTTP status code is a very important part of it. Understanding and obtaining HTTP status codes helps us better handle the data returned by the interface. This article will introduce how to use JavaScript to obtain HTTP status codes and provide specific code examples. 1. What is HTTP status code? HTTP status code means that when the browser initiates a request to the server, the service
How do C++ functions improve the efficiency of GUI development by encapsulating code?
Apr 25, 2024 pm 12:27 PM
By encapsulating code, C++ functions can improve GUI development efficiency: Code encapsulation: Functions group code into independent units, making the code easier to understand and maintain. Reusability: Functions create common functionality that can be reused across applications, reducing duplication and errors. Concise code: Encapsulated code makes the main logic concise and easy to read and debug.
