AMD Big Navi Rumored To Be Twice As Powerful As Radeon RX 5700 XT
According to recent rumblings, Big Navi could have some big performance credentials backing it up, if a new report from ChipHell is accurate. The GPU running the show is reportedly called Navi 21 and it features second-generation RDNA 2 architecture (first-generation RDNA underpins the Radeon RX 5500/5600/5700 series).
But the big news is that Big Navi reportedly also features a whopping 80 CUs (Radeon Compute Units). This is exactly twice as many CUs as found in the Radeon RX 5700 XT, which could have us looking at a card theoretically offering twice the performance of AMD's current-gen top-end Navi card. This rumor definitely sounds promising, although we don't know what kind of thermal constraints AMD will be running into with the 7nm+ process that it will likely be employing for Big Navi.
Regardless, on thing is for sure and it's that AMD CEO Dr. Lisa Su has indeed confirmed that "Big Navi" is coming, on multiple occasions since CES 2020. "My main message to our fans is this is just a beginning for us in 2020. I’ve heard a little bit through Twitter and Reddit that people are wondering about, you know, Big Navi," said Su in a recent interview on an episode of The Bring Up. "I can say you’re gonna see Big Navi in 2020."
At this point, we don't know what the official product name of Big Navi will be, although we've seen product registrations submitted to the EEC that reference Radeon RX 5800 XT and Radeon RX 5950 XT. Hopefully, we'll find out soon enough...
