AMD Radeon RX 6700 XT

The RX 6700 XT's strongest measured trait is frames per $100 at 15.3 fps/$100, which puts it in the 58th percentile — that metric describes raw frames bought per hundred dollars, before any age weighting. Its weakest is ray tracing retention at 27% of raster (2nd percentile). That is a wide spread for a single card: it is specialised rather than balanced, and whether it suits you depends on which of the two you actually load.

The RX 6700 XT turns a 230W board power budget into 73.4 fps at 1440p, or 0.32 fps/W against a pool median of 0.32 fps/W. Power, not transistor count, is the binding constraint on a modern GPU — Dennard scaling stopped holding around 2005, and Esmaeilzadeh and colleagues showed at ISCA 2011 that the fraction of a chip that can be powered at full speed shrinks with every node (“dark silicon”). Frames per watt is the shortest honest summary of what an architecture is doing with that budget.

For scale: the closest AMD card from an earlier generation is the AMD Radeon RX 5700 XT 50th Anniversary (2019), at 53.1 fps and 225W. The RX 6700 XT is 38% faster and draws 5W more.

Every rendered pixel has to be fed from memory. At 1440p the RX 6700 XT has 1,419 B/px of memory bandwidth available per pixel it draws, against a median of 1,808 B/px — a tight ratio, which is why its frame rate falls off harder than its shader count suggests as resolution and texture quality climb. This is the roofline model applied to a game frame: Williams, Waterman and Patterson (Communications of the ACM, 2009) showed that any workload runs into either a compute ceiling or a memory-bandwidth ceiling, and that the ratio of the two is what decides which one you hit.

The RX 6700 XT ranks #44 in 3DMark Steel Nomad but #39 on the 1440p game average — 5 places higher in real games than the synthetic implies. Steel Nomad is a 4K, non-ray-traced pass with heavy async compute and no upscaling, so it rewards raw shader and bandwidth throughput and ignores driver overhead, geometry front-end limits, and everything a game engine does outside the compute path. A gap this size means the card punches above its raw throughput in actual games.

On memory capacity, the RX 6700 XT carries 12GB against a median of 8GB across the 10 other cards within 10% of its 1440p frame rate. It carries more memory than its performance class typically ships with, which mostly matters for high-resolution textures, local AI models, and viewport-heavy creative work rather than frame rate.

Method: percentiles are computed over the 77 non-legacy cards with a 1440p figure. Frame rates come from Tom's Hardware GPU hierarchy; specifications from manufacturer datasheets. Theoretical FP32 TFLOPS is deliberately not used as a cross-vendor comparison — RDNA 3 and 4 dual-issue FP32 doubles the paper figure without doubling game performance, and AMD itself declined to count it as extra shaders. The measured Steel Nomad score is used as the compute proxy instead. GPURanker does not run its own benchmarks.
