Performance: Radeon RX 9070 XT vs Radeon RX 7800 XT
The Radeon RX 9070 XT is dramatically faster, around 41% ahead of the Radeon RX 7800 XT. That gap is enough to move it up a tier: the Radeon RX 9070 XT is comfortable at 4K with upscaling and native 1440p, while the Radeon RX 7800 XT is better matched to 1440p. The Radeon RX 9070 XT packs 4,096 stream processors versus 3,840 on the Radeon RX 7800 XT.
Price & Value
Right now the Radeon RX 7800 XT starts at $680 CAD against $1,000 CAD for the Radeon RX 9070 XT. Despite being slower, the Radeon RX 7800 XT offers the better performance-per-dollar, so budget-focused buyers should weigh it carefully. The Radeon RX 7800 XT still sits about $181 CAD above its $499 CAD MSRP. The Radeon RX 9070 XT still sits about $401 CAD above its $599 CAD MSRP.
Power & Efficiency
The Radeon RX 7800 XT is the lighter draw at 263W against the Radeon RX 9070 XT's 304W, making it the easier card to power and cool. The Radeon RX 9070 XT draws more in absolute terms but squeezes out more performance per watt, so budget for a beefier PSU if you go that route. Its more modern RDNA 4 architecture on a TSMC N4 process is part of why it does more with each watt.
Generation & Longevity
The Radeon RX 9070 XT is roughly 2 years newer than the Radeon RX 7800 XT (RDNA 4 vs RDNA 3), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 7800 XT or Radeon RX 9070 XT?
Choose the Radeon RX 9070 XT if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 7800 XT stretches your money further for only slightly lower performance.
