Radeon RX 7800 XT vs Radeon RX 6800: In-Depth Breakdown

Performance: Radeon RX 7800 XT vs Radeon RX 6800

The Radeon RX 7800 XT is significantly faster, around 19% ahead of the Radeon RX 6800. Both cards sit in the same broad class, well suited to 1440p.

Price & Value

The Radeon RX 6800 currently lists from $4,676 BRL, $1,713 BRL less than the Radeon RX 7800 XT at $6,389 BRL. Despite being slower, the Radeon RX 6800 offers the better performance-per-dollar (~14% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6800 still sits about $4,097 BRL above its $579 BRL MSRP. The Radeon RX 7800 XT still sits about $5,890 BRL above its $499 BRL MSRP.

Power & Efficiency

On power, the Radeon RX 6800 is the gentler choice at 250W versus 263W. The Radeon RX 7800 XT is more efficient per watt because it's faster, but its higher 263W draw means more heat and a bigger PSU. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.

Memory & Bandwidth

The Radeon RX 7800 XT's memory is faster — 624 GB/s versus 512 GB/s — which helps feed the GPU at 4K and with heavy textures.

Generation & Longevity

The Radeon RX 7800 XT is roughly 3 years newer than the Radeon RX 6800 (RDNA 3 vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.

Which should you buy: Radeon RX 6800 or Radeon RX 7800 XT?

Choose the Radeon RX 7800 XT if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 6800 stretches your money further for only slightly lower performance.

Frequently Asked Questions

Is the Radeon RX 7800 XT better than the Radeon RX 6800?
