The AMD Big Navi may have twice the performance of the Radeon RX 5700 XT, making it a graphics card that could be a serious competitor to the rumored Nvidia GeForce RTX 3080

According to tech leaker Rogame, the Big Navi GPU (currently believed to be codenamed Sienna Cichlid) will likely have 80 compute units (CUs) in its top configuration Previously, it was believed that Big Navi would have 72 CUs divided into two 36-CU clusters

However, Big Navi's maximum configuration may have twice as many CUs as the RX 5700 XT's 40 CUs The latter graphics card is the most powerful AMD GPU available for purchase today, and the Navi card utilizes AMD's latest RDNA GPU architecture

However, Big Navi will use the same RDNA 2 GPU architecture as the PS5 and Xbox Series X GPUs, promising more performance per watt than the previous generation RDNA the Radeon RX 5700 XT performance that was roughly comparable to the GeForce RTX 2070, we have high expectations for Big Navi

Rogame tweeted a table showing some of the specs for Big Navi, which is believed to be called Navi 21 inside AMD According to it, the upcoming GPU will have four shader engines, two shader arrays per shader engine, and 10 CUs per shader array All of this adds up to 80 CUs [According to WCCFtech, 80 CUs equals 5,120 stream processors, which means that if AMD can run Big Navi at a clock speed of about 1,700 MHz, Big Navi by itself can deliver 175 teraflops of computing power per second Combined with a powerful CPU, Big Navi is expected to make for a very powerful gaming PC

Leaked information to date suggests that Big Navi is 40% to 50% more powerful than the Nvidia GeForce 2080 Ti, the most powerful consumer graphics card available today It could also outperform the GeForce RTX 3080, which is expected to be announced between August and October

However, these specs and projected power need to be reflected in actual gaming performance This is often determined by GPU drivers, compatibility, and other optimizations So while Big Navi looks good on paper, it should deliver the promised performance in actual testing, which is expected to appear between September and November

It is also worth noting that this Navi 21 list may actually refer to other upcoming GPUs from AMD One of these cards could be the Radeon RX 5800, for example

If so, Big Navi could be even more powerful However, since there is no official announcement from AMD, we can only speculate

In any case, these leaks and other rumors together suggest that the Big Navi will be an impressive graphics card It would also have to be, given that Nvidia is introducing a new GeForce graphics card based on the new Ampere GPU architecture
