Head-to-head, with the AI-workload verdict.

GPU Comparisons

Comparisons take two or three GPUs readers actually consider against each other and walk through them with an AI workload lens — not a gaming review lens.

How this category works

Every comparison starts from the same question structure: which card holds more of your target workload, how much faster is the headline winner at the same quality settings, what does price-per-image-per-second (or per-frame) look like at street prices, and what is the resale floor on the loser two years out.

Where the canonical answer changes by workload, the article makes that explicit. A 5090 versus 4090 verdict shifts depending on whether you're running SDXL Hires Fix or Flux Dev at 1024×1024, and we say so rather than collapsing the comparison to a single 'winner.'

Used-market matchups (3090 vs 4090, used 3090 vs new 4070 Super) deserve special attention in 2026 because the used market shifts roughly every quarter as new generations release. Every comparison guide notes the date of the last price check at the top.
