Overview
The AMD Radeon RX 7900 XTX is AMD’s RDNA 3 (Navi 31) desktop graphics card with 24 GB of GDDR6 memory, 6,144 shading units and a boost clock of 2500 MHz. These are the manufacturer’s published figures. They describe what the chip is designed to do, not what your particular machine does with it, and the gap between those two is usually cooling. A boost clock is a ceiling rather than a promise, and how long a graphics card holds it under continuous load is the one thing no specification sheet can tell you.

Comparable within an architecture. Across vendors or generations it is not a like-for-like count.
Board power, not measured draw. A laptop GPU's power is a range the laptop maker chooses within.

What these numbers mean
Every figure on this sheet 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.
