Intel Arc B580 vs AMD Radeon RX 6600

On paper, the Intel Arc B580 carries more memory (12 GB against 8 GB), the Intel Arc B580 has more shading units, and the Intel Arc B580 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.
