After the birth of the RDNA architecture and navi core, AMD has released the RX 5700 series, the RX 5500 series, and then the RX 5600 series, but they are not enough to challenge NVIDIA’s dominance at the high end, and there is no real heir after the retirement of their own Radeon VII. According tomedia reports, AMD is preparing the code-named “Navi 21” of the large core, positioning the flagship level, based on the second generation of RDNA architecture, and the same second generation of 7nm plus manufacturing process, the core area will also reach 505 square millimeters, is the existing 251 square mm Navi 10 a full double!
By contrast, the Radeon VII Vega 20 core is only 331 square millimeters, the Navi 21 is half the size of it, and is close to the 545 square millimeters of the RTX 2080 TU104 core, although the latter is a 12nm process.
The second-generation RDNA architecture of the Navi 21 core includes hardware ray tracing support, but according to AMD, not all light-tracing calculations are handed over to the hardware unit, but are distributed in conjunction with software solutions.
The memory aspect naturally with the high-capacity GDDR6, professional graphics card is also expected to be paired withSK Hynix’s latest HBM2E, bandwidth than HBM2 increased by about 50%, with 1024-bit bit width can provide 460GB/s ultra-high bandwidth, while a single capacity of up to 16GB, is twice the current.
The Navi 21 core graphics card is said to be double the performance of the RX 5700 XT and is expected to be as low as the RTX 2080 Super, RTX 2080 Ti, and may be used to force the RTX 2080 Ti Super, or even the next generation of the RTX 30 series.
