# GPU Perf Prophet GPU spec database (schema_version 1.0). spec_confidence: verified = vendor spec sheet/whitepaper, estimated = derived from architecture docs/cross-refs. peak_tflops are DENSE (no structured sparsity); AMD uses MFMA instruction peak, NVIDIA uses Tensor Core peak for BF16/FP16/FP8 and scalar CUDA-core for FP32; hbm_bandwidth_tbps is peak theoretical; ~ (null) means unsupported on that GPU. in_model_scope true = exposed as a v1 recommendation target, false = in the training corpus only (Blackwell family, edge GPUs, multi-SKU combos). aliases = every unique accelerator_model_name seen in MLPerf v4.1–v6.0 system JSONs for this GPU, incl. case/suffix variants without the "(xN)" count specifier.
