AMD confirms increased power consumption for Radeon RX 7000 series
AMD will launch Navi 3x series GPUs based on the RDNA 3 architecture this year, corresponding to the Radeon RX 7000 series graphics cards. As the release time approaches, TomsHardware recently interviewed Sam Naffziger, senior vice president, corporate researcher, and product technology architect at AMD, about the development of Radeon graphics cards and what to expect in the future.
Sam Naffziger has been with AMD for 16 years, overseeing multiple product areas, and focusing on driving performance-per-watt improvements to improve AMD’s competitiveness in CPUs and GPUs. He is also one of the main drivers behind AMD’s chiplet architecture, and a similar line of thinking has been successful with the Ryzen and EPYC series of CPUs.
With the introduction of the 16Pin PCIe 5.0 power supply interface, the GeForce RTX 40 series graphics cards based on the Ada Lovelace architecture seem to have higher power consumption. Sam Naffziger said that the total power consumption of next-generation GPUs will increase, and the increase in efficiency is to maximize performance on top of this, the current demand for gaming and computing performance is accelerating. “It’s really the fundamentals of physics that are driving this,” Naffziger explained. “The demand for gaming and compute performance is, if anything, just accelerating, and at the same time, the underlying process technology is slowing down pretty dramatically — and the improvement rate. So the power levels are just going to keep going up. Now, we’ve got a multi-year roadmap of very significant efficiency improvements to offset that curve, but the trend is there.”
