    AMD Radeon fans could be in for a massive surprise in a good way as the company may be working on some insanely powerful next-gen RDNA 3 GPUs. According to the latest report by Twitter leakster Greymon55, the top of the line RDNA 3 (Navi 31) graphics card could come in with close to 92 TFLOPs of single-precision (FP32) compute power. This number is nearly four three times more than AMD's current best offering, the RX 6900 XT, which is capable of delivering 23.04 TFLOPs of FP32.

     

     

    The 92 TFLOP number is reached using a 3GHz boost clock for next-gen flagship Navi 31 GPU, which might be the Radeon RX 7900 XT. Navi 31 is rumored to feature a total of 120 Workgroup Processors (WGPs) or 240 Compute Units (CUs) for a total of 15,360 Stream Processors. This is how the rumored specifications compares with the RX 6900 XT:

     

      RX 6900 XT RX 7900 XT
    Workgroup Processors (WGP) 40 120
    Compute Units (CUs) 80 240
    Stream Processors 5,120 15,360
    Boost Clock 2,250 MHz 3,000 MHz (?)
    FP32 TFLOPs 23.04 ~92

     

    Additionally, earlier today, a driver leak suggested that AMD's RDNA 3 architecture is moving to a four SIMD32 design per CU up from two SIMD32. Hence, the total final performance of the 7900 XT may even end up being more than four times that of the RX 6900 XT.

    AMD's RX 7900 XT could be more than four times faster than the current flagship RX 6900 XT

     

    EDIT: Title changed from "...more than four times faster..." to "...four times as fast..." to correct this mathematically challenged journo. (92 - 23 = 69 faster = three times faster)
