Performance Analysis
The FP32 performance of the RTX 2080 stands at 10 TFLOPS against 19.2 TFLOPS for the RTX A4000. This difference indicates the RTX A4000 processes floating point operations nearly twice as fast in dense FP32 workloads. Memory bandwidth remains equal at 448 GB/s for both so batch size handling depends more on available VRAM capacity. The RTX 2080 provides dense FP16 at 40.3 TFLOPS while the RTX A4000 lists FP16 with sparsity at 153.4 TFLOPS. Direct ratios apply only within matching categories of dense or with sparsity.
