The theoretical computing performance of the internal graphics unit of the processor with simple accuracy (32 bit) in GFLOPS. GFLOPS indicates how many billion floating point operations the iGPU can perform per second.
Some of the CPUs listed below have been benchmarked by CPU-Benchmark. However the majority of CPUs have not been tested and the results have been estimated by a CPU-Benchmark’s secret proprietary formula. As such they do not accurately reflect the actual Passmark CPU mark values and are not endorsed by PassMark Software Pty Ltd.
