Which is better for 4K gaming?

The RX 9070 XT. Its 16 GB of memory and higher raster performance hold up better at 4K, and reviewers put it on par with or ahead of the 5070 Ti.

Is the 5070 worth it over the 9070 XT?

Only if you value DLSS 4, lower power draw and steadier drivers more than raw speed. The 9070 XT is the faster card, so the 5070 has to be clearly cheaper to make sense.

The RX 9070 XT, with 16 GB GDDR6 on a 256-bit bus against 12 GB GDDR7 on the RTX 5070.

Will either card fit my case?

Check clearance first. The 9070 XT is 12 in and triple-slot; the Gigabyte 5070 is 17 in long.

Do I need a new power supply?

The 5070 runs a single 8-pin at 250 W class. The 9070 XT draws more and most models use a second connector, so check your PSU's wattage and cables.

The 5070's dual-fan cooler and lower power draw usually make it the quieter card. Reviewers called the 9070 XT quieter than the 6700 XT, but it still runs hotter.
