AMD says its first graphics products based on RDNA 3 GPU architecture will debut later this year when the first Navi 3X GPUs arrive. And next year we’ll see the first mobile chips with RDNA 3 graphics baked in, when AMD launches its Phoenix Point processors that pair Zen 4 CPU cores with the company’s new graphics architecture.

So what can we expect from RDNA 3? According to AMD, a lot.

The company says its next-gen GPU architecture will deliver a 50% improvement in performance-per-watt compared with RDNA 2. That means the company will either be able to deliver 50% more performance without increasing power consumption, or RDNA 2-level graphics performance in energy-efficient designs that consume half the power.

That bodes well for Phoenix Point and other upcoming mobile processors expected to ship with RDNA 3 integrated graphics, since they’ll be able to offer better graphics performance without taking a significant toll on battery life.

AMD hasn’t provided a lot of details about how it’s going to deliver on that promise yet, but the company has dropped a few clues. First, RDNA 3 GPUs will be manufactured on a 5nm process, compared with the 7nm process used for RDNA 2. Second, the company says the new GPUs will use “next generation AMD Infinity Cache technology,” for increased memory bandwidth, and a chiplet-based design.

The move from a single-chip solution to a series of chiplets, which allows AMD to manufacture a series of small specialized chips for different functions and then put them together into a combined package.

The chip maker has also hinted that RDNA 4 graphics architecture will debut in Navi 4x GPUs sometime by the end of 2024, but the company hasn’t made any performance claims yet.

  1. Maybe AMD will dominate the gaming handheld market that’s been growing.

    There’s excitement over the upcoming 6600U/6800U handhelds especially compared to their Intel variants. We’ll see if this actually translates to more AMD handheld sales than Intel ones.

  2. I guess this is good news for future PC gaming hand-helds which mostly run on battery power. Other than less fan noise on laptop gaming machines, I am not sure how this improvement will be significant. I am only interested in how much higher stock clocks will be at the normal power point.

    1. I’m very much looking forward to improved efficiency. Given what we’ve heard so far about the increase in wattage for even the lower tier next gen Nvidia offerings, I really hope AMD is going to provide some more sensible options that don’t require burling through energy like it’s nothing (and the cooling and space requirements to go with it).

  3. Okay.
    Wake me in two years when they finally start coming down to MSRP and you can find them in stores.
    Just in time for the next paper launch, so you always feel either inadequate or cheated!
