NVIDIA GeForce RTX 5090 vs AMD Radeon RX 7900 XTX

On paper, the NVIDIA GeForce RTX 5090 carries more memory (32 GB against 24 GB), the NVIDIA GeForce RTX 5090 has more shading units, and the NVIDIA GeForce RTX 5090 has a wider memory bus. Shading-unit counts are not directly comparable across different architectures, so read that row as context rather than a verdict. Specifications describe what each card is designed to do; how much of that either one holds under continuous load is a separate question.

A check marks the higher figure only on rows where higher is unambiguously better. Rows without one are not ties; they are specifications where “better” has no meaning.

More comparisons

Every figure on this table is a design target. None of it is a measurement.

Nothing above describes how a graphics card behaves twenty minutes into a sustained workload, which is where two chips with nearly identical specifications routinely diverge. A boost clock is a ceiling the vendor permits, not a rate the chip sustains, and whether it holds depends on the cooling, the case, the power profile and the room. None of those appear on a specification sheet.

We deliberately do not reduce these figures to a single score. A composite invented from specifications would look authoritative and measure nothing, and choosing the weights would be choosing the winner.
