Performance Analysis
The MI300X vastly outpaces the RTX 2080 Ti in AI-relevant compute: 1307 TFLOPS FP16 supports accelerated training of deep neural networks, where half-precision computations reduce memory use without sacrificing accuracy. Its FP32 performance of 163 TFLOPS exceeds the RTX 2080 Ti's 10.1 TFLOPS, benefiting general-purpose simulations requiring single-precision arithmetic.
Memory specifications transform real-world workloads. The MI300X's 5300 GB/s bandwidth and 192 GB HBM3 VRAM enable massive batch sizes in model training, fitting billion-parameter LLMs entirely on one GPU and minimizing data transfer bottlenecks. The RTX 2080 Ti's 616 GB/s and 8-11 GB GDDR6 limit it to smaller batches, often necessitating gradient accumulation or multi-GPU setups.
Power and form factors reflect deployment scales: MI300X at 750W in OAM with Infinity Fabric and PCIe 5.0 suits clustered supercomputing, while RTX 2080 Ti's 215W PCIe design fits desktops but struggles with sustained high-throughput inference.
