NVIDIA GeForce RTX 3080

The RTX 3080's strongest measured trait is 4K retention at 64% of 1440p, which puts it in the 69th percentile — that metric describes how much of its 1440p frame rate survives the jump to 4K. Its weakest is frames per watt at 0.30 fps/W (42nd percentile). The spread is narrow, so the card behaves consistently across workloads rather than trading one strength for one weakness.

The RTX 3080 turns a 320W board power budget into 96.4 fps at 1440p, or 0.30 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 NVIDIA card from an earlier generation is the NVIDIA GeForce RTX 2080 Ti (2018), at 75.6 fps and 250W. The RTX 3080 is 28% faster and draws 70W more.

Every rendered pixel has to be fed from memory. At 1440p the RTX 3080 has 2,139 B/px of memory bandwidth available per pixel it draws, against a median of 1,808 B/px — comfortably fed, so its shaders are the limit before its memory is. 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 RTX 3080 ranks #21 in 3DMark Steel Nomad but #26 on the 1440p game average — 5 places lower 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 hardware on paper is ahead of what the driver and engine mix currently extract from it.

On memory capacity, the RTX 3080 carries 10GB against a median of 16GB across the 11 other cards within 10% of its 1440p frame rate. It has less memory than the cards it competes with on speed, which is the constraint to watch: a card fast enough to run high texture settings but short on VRAM to hold them stutters rather than slows.

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.
