I'm considering upgrading from a Radeon RX 6800 to an RX 9070 XT and would like to know how substantial the real-world difference would be. I play at 1440p and 4K, and my current system has an Intel Core i7-9700K, 32GB of DDR4 RAM, and a PCIe 3.0 platform. I'm especially wondering about performance gains, ray tracing, upscaling, and whether the older CPU could bottleneck the new graphics card.

I made essentially the same upgrade and found it very noticeable. At ultrawide 1440p, I went from adjusting settings on the RX 6800 to running modern games at high settings with steady native-resolution performance. The improvement is even more apparent in demanding AAA titles and ray-traced games.
The RX 6800 is still a capable card, particularly for standard 1440p gaming, so the upgrade is not essential if you are happy with your current frame rates. However, the 9070 XT offers much better ray tracing, newer FSR support, and more headroom for high settings and 4K. If you are keeping the 9700K for a while, upgrading the GPU now is reasonable, but a future CPU and motherboard upgrade would help you get its full potential.
Your i7-9700K may hold the 9070 XT back in some CPU-heavy games, particularly at lower resolutions or when targeting very high frame rates. At 4K, the graphics card will usually remain the main limitation, so the upgrade makes more sense there. At 1440p, it can still be worthwhile, but the benefit will vary by game.
Whether it is worth the money depends on your target frame rate and the games you play. Older or CPU-heavy games may show a smaller improvement, while newer AAA games, ray tracing, and 4K workloads should benefit considerably. If the RX 6800 is already meeting your needs, you could also keep it and save toward a complete platform upgrade.
Yes, it should be a significant upgrade, especially at 1440p and 4K. The 9070 XT is roughly 70–75% faster in conventional rendering and is also much stronger with ray tracing and newer upscaling features. The exact gain depends on the games and settings, but it is a substantial GPU upgrade rather than a minor sidegrade.
I’m using an i7-9700K with 32GB of DDR4 at 1440p and 4K. I’m mainly worried that the processor could limit the upgrade.

That makes sense. I play at both resolutions, so I may see the biggest improvement in 4K and in graphically demanding games.
