Performance Analysis
The MI300X delivers 1307.4 TFLOPS dense FP16 compared with 40.3 TFLOPS dense FP16 on the RTX 2080 which produces a ratio of roughly thirty two times greater dense FP16 throughput on the MI300X. The same pattern holds for FP32 where the MI300X supplies 163.4 TFLOPS against 10 TFLOPS on the RTX 2080. Memory bandwidth of 5300 GB/s on the MI300X versus 448 GB/s on the RTX 2080 permits substantially larger batch sizes during training and inference workloads. The MI300X further provides 2614.9 TFLOPS FP16 with sparsity which has no counterpart listed for the RTX 2080. These differences translate into the MI300X handling larger models at higher throughput while the RTX 2080 remains constrained by its lower memory capacity and bandwidth.

When to Choose the MI300X
The MI300X suits workloads that require 192 GB HBM3 memory and 5300 GB/s bandwidth such as large scale LLM training or scientific computing that utilize 1307.4 TFLOPS dense FP16. Its 750W TDP and Infinity Fabric interconnect support sustained operation in data center environments where the 163.4 TFLOPS FP32 figure accelerates precision sensitive tasks.
When to Choose the RTX 2080
The RTX 2080 suits workloads that fit within 8 to 11 GB GDDR6 memory and operate at a 215W TDP such as smaller inference jobs or development tasks that utilize 40.3 TFLOPS dense FP16. Its PCIe form factor and 10 TFLOPS FP32 performance align with power limited or legacy system deployments.
Use Cases
The MI300X supplies 192 GB HBM3 memory and 1307.4 TFLOPS dense FP16 which exceed the RTX 2080 limits for large model training.
The MI300X supplies 5300 GB/s bandwidth and 2614.9 TFLOPS FP16 with sparsity which support higher throughput inference than the RTX 2080 40.3 TFLOPS dense FP16.
The MI300X supplies 163.4 TFLOPS FP32 and 192 GB memory which accommodate fine tuning of sizable models beyond the RTX 2080 8 to 11 GB capacity.
The RTX 2080 operates at 215W TDP with 40.3 TFLOPS dense FP16 which suffice for moderate image generation workloads within its 8 to 11 GB memory.
The MI300X supplies 163.4 TFLOPS FP32 and 5300 GB/s bandwidth which accelerate compute intensive simulations beyond the RTX 2080 10 TFLOPS FP32.
