AMD is using some innovative solutions to reduce TDP as much as possible
In recent years, each generation of new graphics cards has higher and higher requirements for PC power supply, and the improvement is quite obvious. AMD will launch Navi 3x series GPUs based on the RDNA 3 architecture this year, corresponding to the Radeon RX 7000 series graphics cards. According to the power calculator provided by Seasonic, the desktop high-end platform chooses Radeon RX 7800/7900 XT, and the recommended minimum power supply specification is 850W. If you switch to Radeon RX 7700 XT, the minimum power supply specification is 650W.
Recently, AMD senior vice president, enterprise researcher, and product technology architect Sam Naffziger accepted an interview with VentureBeat, saying that by 2025, the TDP of high-performance GPUs will reach 700W. Sam Naffziger did not talk specifically about the technical aspects of energy efficiency. However, it can be understood that AMD is using some innovative solutions to reduce TDP as much as possible, involving some design skills on the RDNA 3 and RDNA 4 architectures.
In fact, in another previous interview, Sam Naffziger said that the total power consumption of next-generation GPUs will increase. The increase in efficiency is to maximize performance on top of this, and the demand for gaming and computing performance is currently accelerating. At the same time the underlying process technology is slowing down, power levels continue to rise is a big trend, and efficiency improvements are just offsetting this curve as much as possible.
Sam Naffziger has been with AMD for 16 years and has been with the Embedded Graphics division since 2017, overseeing multiple product areas, focusing on driving performance-per-watt improvements, and one of the main drivers behind AMD’s chiplet architecture. Sam Naffziger is also currently working on AMD’s 30×25 project, in artificial intelligence (AI) training and high-performance computing (HPC) applications running on accelerated compute nodes by 2025, AMD EPYC series processors, and AMD Instinct compute cards will be 30 times more energy efficient.
