As per one of the leading technology websites for Linux hardware and benchmarks, Phoronix, 200 patches of AMD’s Radeon Linux driver that have just been released by the company consist of support for a graphics card codenamed ‘Sienna Cichlid’.

Since the name doesn’t reveal any possible information about the card, it means they urge to keep things under wraps until they are ready to launch the major product. However, the patches show that Sienna Cichlid is a Navi-based graphics card with DCN 3.0 (Display Core Next and VCN 3.0 support on the video encoding side. On the contrary, existing Navi products run with version 2.0 on both those fronts.

Putting it differently, this could be a point to step on from the RDNA architecture to RDNA 2, which will be utilized in AMD’s upcoming next-generation graphics cards, led by Big Navi or Navi 21.

A lot has been heard about the Big Navi GPU. Most recently, it revealed that Big Navi GPU will come in four different flavors. Although the specifications of the card are already circulating on the internet, we don’t have any idea of its performance compared to its rival NVIDIA’s GPUs.

And if we talk about RDNA 2 architecture in the Big Navi graphics card, it offers a 50% increase in its performance per Watt compared to the original RDNA architecture. That’s one promising thing by the company about this card.


Previously, AMD announced that Big Navi will arrive later in 2020. So far, it was expected to be launched by the company in September, when NVIDIA would also be releasing its next-generation Ampere GPUs.

But the recent Linux driver spillage points that Big Navi launch might happen in October. That’s because the company won’t introduce Sienna Cichlid patches until the Linux 5.9 merge window opens in August.
