Amd announced the launch of the radon Rx 6900xt on December 8 for $999

amd RX 6900 XT is the flagship model of rx6000 series and will compete with geforce RTX 3090 graphics card. In terms of parameters, RX 6900 XT has 80 computing units, namely 5120 stream processors, 16GB gddr6 video memory and 128MB infinity cache

Amd claims that the total power consumption of this video card is only 300W, 50W lower than rtx3090. The RX 6900xt has the same game / acceleration frequency as the RX 6800xt: 2015 / 2250 MHz

according to the test data of AMD, in the 4K game, Rx 6900xt and RTX 3090 have different levels in the open acceleration mode

extended information:

the first models include RX 6900 XT, RX 6800 XT and Rx 6800, which are all based on the Navi 21 core, followed by the RX 6700 series and the Navi 22 medium core

RX 6900 XT is most expected as a flagship card, but it can be confirmed that there are only public cards, and the number is limited, so there will be no non-public cards. AIB brands can only get RX 6800 XT at most

the performance of Rx 6900 XT is expected to basically catch up with RTX 3080, and Rx 6800 XT will be able to draw with RTX 3070 at most, which means that AMD has given up the competition for the commanding height and directly fought in the mid market

4. According to the latest statistical results of dramaxchange, a memory instry observer, the DRAM agreement price has broken through the highest point in the last 18 months. Only one month after entering 2017, the agreement price of 4GB DDR4 memory granule has risen from US $2.837 to US $3.347, up 18%! This is just the price of raw materials for the upstream manufacturers. The cost of memory controller, PCB and assembly in the middle is graally rising. It can be imagined that the retail price of a finished memory proct will rise greatly
DRAM particles are seriously out of stock
price rise is always inseparable from the supply and demand relationship of the market. Obviously, the price of memory is rising this time. This is the main reason. Why is DRAM grain out of stock

e to the sluggish memory market, slow upgrading and weak market demand, the major DRAM memory manufacturers have no plans to increase proction, and the main proction capacity will be transferred to 3D NAND flash, resulting in a shortage of DRAM memory supply and demand< DDR3 memory has been in service for eight years since 2007. Compared with Intel's update pace, memory development is quite slow. DDR4 was launched on a small scale in 2015, and the real large-scale market is 2016. Compared with DDR3, DDR4 memory is very different. The voltage, time sequence and frequency all change accordingly. Even golden finger is different. The factory turns from DDR3 to DDR4 memory, which is bound to cause temporary pressure on proction capacity
the RMB exchange rate continues to decline

DRAM in memory and NAND in flash memory are very dependent on imports, and the RMB exchange rate continues to decline. Under the US dollar based monetary system, price rise is an inevitable result. Not only SSD, memory, almost all of the digital electronic procts this year to a certain extent. In the DIY field, including motherboards, chassis, graphics cards and so on, there is a trend of price increase in the near future or the price has begun to rise
guess, there is still an invisible hand

Samsung, SK Hynix and Meguiar have shown a three-way posture in the global DRAM memory market, among which Samsung has absolute advantages in terms of technology, proction capacity and share. After the first mass proction of 20nm DRAM process in 2014, Samsung is leading the way again and has mass proced 18NM DRAM. According to South Korean media reports, Samsung converted 70% of its DRAM capacity to 20nm last year, and now it has entered the era of 18NM, further expanding its leading edge. In contrast, SK Hynix will mass proce 18NM DRAM early next year, while Meguiar is still on the way to 20nm.

5. 1. Pay attention to whether the CPU can be moved or not. The b365m is better to use the CPU with i7 9700K or above.
2. The rated power supply is more than 800W.
3. The length of the chassis should be enough. The b365m is a mATX small board, but the chassis has to use a large chassis to meet the length limit of the graphics card

6. A more standard term is video bandwidth. Calculation method: video memory bandwidth = working frequency × Display memory bit width / 8. For example, if the working frequency of a graphics card is 800MHz and the bit width is 192, the bandwidth is 800 * 192 / 8 = 19200mb / S = 19200 / 1024gb / S = 18.75gb/s. The bit width of the graphics card is very important. The larger the bandwidth is, the higher the bandwidth is. Because the frequency gap is not big, it is difficult to improve it.

Including Huaqing, ASUS, Dylan, gigabyte, Weixing, Zhenxun, sapphire, Xunjing and Yingtong, they will proce RX 6800 and Rx 6800xt graphics cards, which are expected to be available in November 2020

the public RX 6800 and the radon Rx 6800xt graphics card will be launched on November 18, 2020 at the price of 4599 yuan and 5099 yuan respectively. RX 6900xt was launched on December 8, 2020

extended data :

in terms of specifications, RX 6800 has 60 groups of computing units, 3840 stream processors, 1815mhz core game frequency, 2105mhz maximum acceleration frequency, 128MB infinity cache, 256 bit 16GB gddr6 video memory, and 250W whole card power consumption

compared with the competitive RTX 3070, the comprehensive strength is expected to lead by 10%; RX 6800 XT has 72 groups of computing units, 4608 stream processors, core game frequency of 2015mhz and acceleration frequency of 2250mhz. It can run above 2GHz almost all the way

8. I use ASUS v9999td, the temperature should be 65-70 degrees, this is the core temperature, so I suggest you replace the heat sink mole, PCB board should not be 80 degrees, because the temperature is not high now, it may burn in summer, in addition, we should pay attention to the problem of cooling ct in the chassis, it is necessary to install a fan
