Performance comparison with the benchmarks:


Performance comparison between the two processors, for this we consider the results generated on benchmark software such as Geekbench.


FP32 Performance in GFLOPS
AMD Radeon RX 6800M 12,240
AMD Radeon PRO W6400 3,580


The difference is 242%.


Single-precision floating-point format, also called FP32, is a computer number format that typically occupies 32 bits in PC memory. This represents a wide dynamic range of numeric values that employs a floating point. FP32 power helps assess the video card's capabilities for generating rendering workloads. Video games use INT32 and FP32 cores to manage calculations with integers and numbers with decimals in order to produce maps, bone matrices on which the vertex shaders will calculate the vertices. Values in single precision format are mainly used in video games and 3D software.
