Price: For technical reasons, we cannot currently display a price less than 24 hours, or a real-time price. This is why we prefer for the moment not to show a price. You should refer to the respective online stores for the latest price, as well as availability.

We can better compare what are the technical differences between the two graphics cards.


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 7800 XT 37,325
AMD Radeon PRO Vega II Duo 28,180


The difference is 32%.


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.
