Early this morning, amd finally announced the RX 6000 Series graphics card based on rdna2 architecture. It launched the RX 6800, RX 6800 XT and Rx 6900 XT to replace RTX 2080 Ti, RX 3080 and RTX 3090 respectively. The starting price in China is 4599 yuan (US $579 overseas).

Data indicators,Compared with rDNA (Rx 5700 XT), the performance of rdna2 is doubled and the performance per watt is increased by 54%To achieve the goal perfectly.


Back to the GPU architecture itself, what attracts more attention is the newly introduced infinity cache and smart access memory, which is a set of innovative cache and video memory technologies.


AMD revealed that the Infinity Cache is based on Zen3 three-level cache adjustment, the three graphics cards are equipped with 128 MB, benefits including access to ray-tracing data, reduce frequent calls to memory ,256 bit width to achieve greater throughput bandwidth than 384 bit.

As for the intelligent access technology, it allows the CPU to access the full capacity video memory directly, instead of the 256MB previously locked by the PCI device. At the same time, it can reduce the video memory fragmentation and further increase the frequency.

However, AMD noted,At this stage, the intelligent access technology needs to be combined with the Zen3 architecture, Ruilong 5000 processor and 500 main board to use, as to whether it will be open to other Zen architecture processors or competitors in the future, the official said please wait.

As for the game side, some 3 A games have been adapted, but developers can further optimize.
