fp16TFLOPS/bf16TFLOPS/fp8TFLOPS are still intentionally omitted — Intel's ark page for Arc consumer cards does not publish a per-precision matrix/tensor FLOPS breakdown at all, only the single "GPU Peak TOPS (Int8)" figure used here. shaderCoreCount (160) is ark's "Xe Vector Engines" count and matrixCoreCount (160) is its "Intel XMX Engines" count — both structural counts, not throughput figures.
