AMD Radeon RX 7600 XT vs AMD Radeon RX 7800 XT

On paper, the AMD Radeon RX 7800 XT has a wider memory bus. 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.

Reading the table

What the difference means.

A year apart

The RX 7600 XT (RDNA 3, 2024) is a year newer than the RX 7800 XT (RDNA 3, 2023). A newer architecture brings more than speed: newer video encoders and decoders, newer upscaling and frame generation, and a longer run of driver updates ahead of it.

Video memory

Both carry 16 GB, so neither has the advantage where memory is the limit: high resolutions, heavy textures and local AI models fill both at the same point.

Memory bus

The RX 7800 XT moves data over a 256-bit bus of GDDR6; the RX 7600 XT uses 128-bit GDDR6. The bus width and the memory type together set how fast the chip can reach its own memory, which shows at high resolutions where every frame moves more data. A narrow bus with fast memory can match a wide one with slow memory, so neither figure settles it alone.

Board power

The RX 7800 XT draws up to 263 W against 190 W. That is heat the case has to exhaust and current the power supply has to deliver: allow a supply of about 700 W for the RX 7800 XT with a typical processor, and check the card's power connectors against the supply's. A card that cannot shed its heat does not fail. It lowers its clocks after a few minutes, which is the frame rate that falls the longer you play.

Which to pick, on paper

A small case or a modest power supply: RX 7600 XT; 190 W against 263 W: less heat, fewer power connectors, quieter fans.

What no table says

How much of its speed a graphics card keeps after the first minute depends on the cooling and the power limit of the machine it is in. If you own one of these, measure it: the test is free and runs in this browser.

Questions

Is the RX 7600 XT better than the RX 7800 XT?: By need, on the specifications: a small case or a modest power supply: the RX 7600 XT. They share an architecture, so the table is a fair guide. Frame rates depend on the game and its settings, and how much speed either card keeps after ten minutes depends on its cooling, which is what a sustained test measures.
What power supply does the RX 7800 XT need?: Allow about 700 W with a typical processor, and make sure the supply has the power connectors the card uses. The RX 7600 XT at 190 W is easier on both.
Do the RX 7600 XT and the RX 7800 XT have the same features?: Yes. Both are RDNA 3 designs from AMD, so they share the same generation of video encoders and decoders, upscaling and driver support. What separates them is in the table: how much of the chip each one has, and how much power it is given.

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.
