AMD Big Navi GPU May Have 80 Radeon Compute Units; 15 Percent Faster Than NVIDIA GeForce RTX 2080 Ti

AMD’s enthusiast-grade Big Navi GPU is expected to launch around the same time as NVIDIA’s upcoming Ampere-powered GPUs, that is to say, sometime next month. Now, new information has surfaced about one of the alleged Big Navi GPUs and the number of its Compute Units.

The Big Navi GPU goes by the name Sienna Cichlid and goes by the codename Navi 21. According to a screenshot posted by rogame (@_rogame), the GPU could ship out with 80 Compute Units (CUs); specifically, those CUs consist of four shader engines, two shader arrays per shader engine, and 10 CUs per shader array. Multiply those numbers, and that’s 80 CUs in total.

On top of that, it’s also possible, if these numbers hold true from now until its imminent time of launch, we could be looking at approximately 5120 stream processors with Navi 21. That’s a monstrous amount of stream processors and precisely, double the number of stream processors found AMD’s Radeon RX 5700XT graphics card.

Despite those numbers, however, there is speculation that the card still won’t be up to par with NVIDIA’s alleged GeForce RTX 3080 Ti. According to the tech site Coreteks, it’s likely that AMD’s high-end GPU will be on par with its rival’s current RTX 2080 Ti. Technically, that isn’t bad thing, especially since it is NVIDIA’s most powerful consumer-ready desktop graphics card on the market.

Of course, this is all simply speculation and hearsay at this stage, so treat this news with a fairly heavy sprinkling of scepticism.
