RX 7800 XT vs RX 6800 XT
The RX 7800 XT and RX 6800 XT are effectively tied: within 2% of each other at every resolution.
Quick verdict: buy whichever is cheaper on the day, or whichever has the feature you care about.

| Estimated FPS · 4K | 60 | 59 |
| Video memory | 16 GB | 16 GB |
| Board power | 263 W | 300 W |
| Launch price (MSRP) | $499 | $649 |
| PCI Express | 4.0 ×16 | 4.0 ×16 |
| Release year | 2023 | 2020 |
| Series | AMD RX 7000 Series (RDNA 3) | AMD RX 6000 Series (RDNA 2) |
Estimated FPS at 1080p, 1440p and 4K
1080p: the RX 7800 XT leads by 2%. 1440p: the RX 7800 XT leads by 2%. 4K: the RX 7800 XT leads by 2%. These figures come from our performance model, calibrated against published benchmark averages. They are estimates for comparing the two cards, not results measured on your PC.
Estimated FPS in Popular Games at 1440p
| Game (settings) | RX 7800 XT | RX 6800 XT |
|---|---|---|
| Cyberpunk 2077 (High, no ray tracing) | ~80 | ~80 |
| Fortnite (High, DirectX 12) | ~130 | ~125 |
| Call of Duty: Black Ops 6 (High) | ~115 | ~115 |
| Counter-Strike 2 (High) | ~240 | ~235 |
Per-game figures scale each card's modelled 1440p average by how demanding the game is relative to our test blend, rounded to the nearest 5 FPS. Counter-Strike 2 is usually limited by the processor well before these numbers.
Verdict: RX 7800 XT or RX 6800 XT?
The RX 7800 XT and RX 6800 XT are effectively tied: within 2% of each other at every resolution. At that distance you will not see the difference without a frame counter, so memory, features, power draw and price should decide it.
Both cards have 16GB of video memory, so memory is not a reason to choose one over the other.
At launch the RX 7800 XT was $499 and the RX 6800 XT $649, which works out to $5 and $6.6 per frame at 1440p. On those prices the RX 7800 XT is the better value, but street prices move every week, so check before you buy. The RX 6800 XT is rated for 37W more board power, which means more heat, more fan noise and possibly a bigger power supply.
Beyond raw speed, the RX 7800 XT brings FSR 3 frame generation and AV1 encoding, while the RX 6800 XT offers FSR 3 frame generation, with first-generation ray tracing.
Bottom line: buy whichever is cheaper on the day, or whichever has the feature you care about.
Pairing Either Card With a Processor
A faster graphics card only helps if the processor can keep up. Each card's own page lists the slowest CPU that will not hold it back at every resolution:
- Radeon RX 7800 XT: best CPU pairing and bottleneck
- Radeon RX 6800 XT: best CPU pairing and bottleneck
- Check your own processor in the bottleneck calculator
Power supply: a common rule of thumb is the card's board power plus about 150W for the rest of a gaming PC, with 30% headroom. That points to roughly 550W for the RX 7800 XT and 600W for the RX 6800 XT. Check the card maker's own recommendation too.
