AMD is scheduled to hold a financial analyst conference at its headquarters in California from 5:00 a.m. to 10:00 a.m. on March 6, Beijing time,CEO Dr Su Zifeng will announce the Radeon "Big Navi" graphics card. Allegedly, "Big Navi "is the flagship model of three new graphics card products, with single precision (fp32) floating-point performance up to 18tflopsThat is to sayIt's 80% higher than RX 5700 XT or RTX 2080, and 30% higher than radon VII or RTX 2080 ti. It's terrifying。
"Big Navi" or "RX 5950 XT" if the previous one is believed, the other two may be RX 5900 XT and Rx 5800 XT.
According to the rumor that RX 5950 XT has 80 groups of Cu (2 times of Rx 5700 XT), fp32 can also double. Under the core frequency adjustment, it really has the strength to reach 18tflops. However, there are also several problems, such as whether it is a "glue" double core, how to suppress the power consumption (TDP of 5700 XT is 225-235w), and the power consumption of the same 7 nm and 3840 stream processor's radeon VII has reached 300 watts.
Of course, combining the exposed NVIDIA ampere core "fat man" and "little boy", 18t is nothing. For 7552 CUDA and 6912 CUDA respectively, the calculation force of fp32 is as high as 33.5t and 27.9t.
