AMD's RDNA 3 Interview With Tom's Hardware

The next-generation GPUs are going to need more power. That's what Sam Naffziger, Senior Vice President, Corporate Fellow, and Product Technology Architect at AMD, told Tom's Hardware in a recent interview (opens in new tab). Team Red will be pushing the power levels with RDNA 3, he said, to "drive better performance per watt."

Naffziger was behind AMD's chiplet approach for Ryzen Zen and Epyc CPUs, and he explains here that it will take a slightly different approach when applied to graphics cards. For one thing, he says that the chiplets won't operate in parallel and will instead share a single memory subsystem. That allows the GPU to use a much higher clock speed than it would have been able to run at if each core ran separately.

In addition to the increased clock, Naffziger says that RDNA 3 will allow the GPU to do simultaneous encode and decode of AV1 video. That means it will be able to join Intel's Arc and Nvidia's RTX 40 series in offering content creators a more efficient way to process their videos. The increased frequency of the media engine will enable it to offer performance up to 1.8x better than RDNA 2, he adds, cutting down export times. AMD's new AI cores will also contribute, and Naffziger promises improved video encoding and conference call quality thanks to them.

Naffziger didn't give a specific date for when the new graphics cards will be available, but he did say that they will arrive later this year and early next. He added that they will be more affordable than the RTX 20 and RTX 30 series, which have launched recently.
