New Navi 20 members on RDNA 2 are revealed in unit data

The fact that the autumn looks like it will bring a revived war between AMD and Nvidia on the graphics front does not come as news to the enthusiasts, where the top cards built on the architectures RDNA 2 and Ampere seem to be something in the way of horses. That “Big Navi”, “Navi 21” or “Sienna Cichlid” will be a high-performing giant has previously been reported, but the rest of the new family has lived a more anonymous existence.

Now digging @_rogame on Twitter produced device ID for a total of four circuits in the Navi 20 series – where a novelty is the supposed minimum Navi 23. “Big Navi”, or Navi 21 is thus accompanied by two dedicated graphics circuits, while two integrated graphics components in APU processors at names “Van Gogh” and “Van Gogh Lite” enter the scene. The latter will land in the upcoming APU family “Cezanne” in 2021.

According to Wccftech’s estimate, the Navi 23 will be the next generation midrange board for AMD, while Van Gogh forges pixels in the next generation APU processors. For the Ryzen 5000G series, the aging Vega graphics found in the Renoir family are thus seen to be ironed out, while the Navi 22 may replace the recently launched Radeon Pro 5600M with HBM2 memory in Apple’s computers.

Whether the Navi 22 will once again be a special circuit with HBM2 for the mobile market remains to be seen, but if so, AMD’s next generation graphics card consists of only two new dedicated graphics circuits. Navi 21 and 23 will in all probability be launched in several versions with varying numbers of calculation units, or Compute Units (CU), and exactly what the Radeon RX 6000 series will look like at launch is still unclear.

No less than four Navi 21 variants have previously appeared in connection with data on recycled Navi 10 circuits, which with production on TSMC’s refined manufacturing process of 7 nanometers may provide support for the Navi 20 circuits in the middle class. On paper, however, Navi 10 and 23 end up on a collision course with similar circuit surfaces – possibly Navi 23 may focus on lower power consumption in the entry-level class.

As a curiosity, it can be mentioned that AMD seems to make a departure from previous naming with the launch of RDNA 2. Historically, each generation of flagship circuit has been gifted with a code name with a suffix in even tens, but with the Navi 20 series instead the top model looks that become Navi 21 with massive circuit area 505 mm².

The first RDNA 2 graphics cards are said to be based on Navi 21 and are expected to reach retail this autumn.
