Quanteta Performance Indices

Five calculated 0-100 indices, normalized across the whole dataset. Each is a transparent formula over published specifications (compute throughput, bandwidth, clocks, TDP) — analytical indices, not measured game/render benchmarks, and never an editorial opinion.

Overall Performance Index (QOV)
Composite 0-100 index calculated from published specifications — not a measured benchmark. Weighted blend of Compute Strength (30%), Graphics Index (30%), Power Efficiency Index (20%) and Memory Bandwidth Density (20%), normalized across the whole dataset.
Compute (AI) Strength (QAI)
0-100 index for AI and compute workloads, calculated from specs (not a measured benchmark). Derived from FP16 throughput (45%), memory bandwidth (30%) and tensor-core count (25%). Cards with under 8 GB VRAM score 0 on this axis.
Graphics Index (QGP)
0-100 index for graphics / gaming workloads, calculated from specs (not a measured benchmark). Derived from texture rate (35%), pixel rate (25%), memory bandwidth (25%) and boost clock (15%).
Power Efficiency Index (QWP)
0-100 index measuring FP32 throughput per watt of TDP, calculated from specs (not a measured benchmark). Higher means more compute per watt.
Memory Bandwidth Density (QME)
0-100 index measuring memory bandwidth relative to VRAM capacity and bus width — i.e. how dense the memory subsystem is, not overall capability. Calculated from specs (not a measured benchmark). By construction this favours cards with narrow, fast memory and small VRAM, so some older / console GPUs rank highly here. Use it for memory-subsystem analysis, not as a performance ranking.
