What is FLOPS Measurement?
FLOPS (Floating Point Operations Per Second) quantifies computational throughput for comparing AI hardware performance. FLOPS ratings guide hardware selection but don't capture full performance story.
This AI hardware and semiconductor term is currently being developed. Detailed content covering technical specifications, performance characteristics, use cases, and purchasing considerations will be added soon. For immediate guidance on AI infrastructure strategy, contact Pertama Partners for advisory services.
Understanding FLOPS measurements prevents mid-market companies from overspending on hardware that exceeds actual computational needs, with right-sized infrastructure saving 30-50% on cloud GPU budgets annually. Accurate FLOPS benchmarking reveals that a $3/hour GPU instance often outperforms a $8/hour alternative for specific model architectures. This knowledge transforms hardware procurement from vendor-driven upselling into data-driven decisions that align computational investment with genuine business throughput requirements.
- Measures theoretical peak performance.
- H100: 1,979 TFLOPS (FP8), 60 TFLOPS (FP32).
- Lower precision = higher FLOPS (FP8 > FP16 > FP32).
- Actual performance depends on memory bandwidth and utilization.
- Useful for comparison but not absolute predictor.
- PetaFLOPS (10^15) and ExaFLOPS (10^18) for clusters.
- Compare theoretical peak FLOPS against sustained throughput benchmarks, since real-world AI workloads typically achieve only 30-50% of advertised hardware specifications.
- Calculate cost-per-teraFLOP across cloud providers quarterly, as pricing shifts of 20-40% occur frequently during GPU supply fluctuations and new chip launches.
- Match FLOPS requirements to workload profiles: inference tasks need 10-100x fewer FLOPS than training, making hardware right-sizing essential for budget control.
- Factor in memory bandwidth alongside raw FLOPS, since transformer models are often memory-bound rather than compute-bound during practical inference scenarios.

Common Questions
Which GPU should we choose for AI workloads?
NVIDIA dominates AI with H100/A100 for training and A10G/L4 for inference. AMD MI300 and Google TPU offer alternatives. Choose based on workload (training vs inference), budget, and ecosystem compatibility.
What's the difference between training and inference hardware?
Training needs high compute density and memory bandwidth (H100, A100), while inference prioritizes latency and cost-efficiency (L4, A10G, TPU). Many organizations use different hardware for each workload.
More Questions
H100 GPUs cost $25K-40K each, typically deployed in 8-GPU nodes ($200K-320K). Cloud rental is $2-4/hour per GPU. Inference hardware is cheaper ($5K-15K) but you need more units for serving.
