New graphics card is based on RDNA2 architecture，The efficiency and energy consumption ratio have improved significantly compared to RDNA1。The new architecture also brings high-performance CU computing units、The revolutionary Infinity Cache，Breakthrough high-core frequency design, etc.，And support DirectX 12 Ultimate and Light Trailing。
The first one released is RX 6800 XT，Equipped with 72 CU、128MB unlimited cache and 16GB GDDR6 graphics memory，Boost can reach 2250MHz，TBP is 300W。PPT performance is slightly better than 3080。11Sale from 18th of the month，Price ￥5099。
RX 6800 comes with 60 CU、128MB unlimited cache and 16GB GDDR6 graphics memory，Boost can reach 2150MHz，TBP is 250W。PPT performs better than 2080 Ti。11Sale from 18th of the month，Price ￥4599。
The finale RX 6900 XT is equipped with 80 CU、128MB unlimited cache and 16GB GDDR6 graphics memory，Boost can reach 2250MHz，TBP is 300W。PPT performs better than 3090。12Sale from 8th of the month，Price ￥7999。
Infinity Cache is a very interesting thing，AMD uses CPU L3 cache idea，Scan the 256-bit bit width and the bandwidth disadvantages of GDDR6 video memory。Can achieve equivalent bandwidth of 2.17 times，Reduce power consumption。This generation of graphics cards has a slight bonus effect with the "3A platform"，Smart Memory technology was introduced。
Light Trailing is not discussed in the press conference，We know that each CU contains a Ray Accelerator。According to the analysis of foreign media wccftech，The ray tracing performance level of this generation of graphics cards is about 3070。AMD has not come up with technology that benchmarks DLSS，Learn from The Verge's press release，AMD is developing its own supersampling capabilities。
Large video memory、high performance，6000It is a powerful opponent of NVIDIA，30There is a reason for the price reduction。The three graphics cards have the same memory size，CU and frequency are different，Except for the 6800 being a double slot card，The others are 2.5 SLOT cards。We'll see too，AMD focuses on game performance at this press conference，The ray tracing begins to make efforts，But NVIDIA is still leading the way in machine learning。
