Understanding ray tracing cores

Ray tracing cores is a numeric spec measured in raw units. On this metric, higher values are generally better, but returns diminish past category-typical thresholds — going from a low value to a mid value usually matters far more than going from a mid value to a high one. When comparing two products, focus on the percentage gap rather than the raw delta: a 200-unit lead means something very different at the low end of the range than at the high end. Pay attention to the unit, too — manufacturers sometimes quote peak or burst figures that are not sustained in real-world use. Cross-check the published number against independent measurements where possible, especially for performance and battery claims. Finally, remember that a single spec rarely tells the whole story; the Mars Score weighs ray tracing cores together with the rest of the spec sheet so one outlier doesn't distort the verdict.

This matchupIn this spec, GeForce RTX 5080 and Radeon RX 7900 XT are effectively tied at 84 — buyers can treat them as equivalent on ray tracing cores alone.
