As soon as October is about to enter, NVIDIA RTX 3070 will be on sale, and 3060 may also be on the market. For the October 28 rdna2 architecture RX 6000 Series graphics card, the pressure is not small.

Through the mining of ROCM 3.8 software, Mac OS Big Sur 11 beta and other systems, more details of Navi 2x core based on rdna2 come out of the water.

Among them,The large core Navi 21 code named Sienna cichlid has built-in 80 sets of Cu, that is, 5120 six processors. The GPU acceleration frequency can reach 2050mhz. Navi 21b can touch 2200MHz, which corresponds to the thermal design power consumption of 220 ~ 238w


In terms of performance, only single precision (fp32) is achieved, Navi 21 is 22.5tflops. In simple comparison, this is 24% less than RTX 3080's 29.8t, but 10% higher than RTX 3070 (20.4t), and more than double that of our own RX 5700 XT

Navi 22, Navy flonder, 40 sets of Cu,It is said that the acceleration frequency is as high as 2500mhz, and the power consumption is only 170 watts. In other words, compared with the previous generation core RX 5700 XT, the frequency is 31% higher, the single precision is improved by 30%, and the power consumption is reduced by 55 watts.

NAV 23 code named dimgrey cavefish has only 32 sets of Cu (2048 stream processors).

Interestingly, apple system has also stolen the Navi 31 core. Is it the RX 7000 Series graphics card of rdna3?
