The Radeon RX 9070 XT outperforms the RX 9070 by 12 percent on average

The Radeon RX 9070 XT provides a 12 percent performance advantage over the standard RX 9070 across a wide range of gaming benchmarks at both 1440p and 4K resolutions. While the two cards share identical memory specifications, including 16GB of 20Gbps GDDR6 on a 256-bit bus, the XT variant features a 14 percent higher core count and significantly higher clock speeds. The non-XT model is generally priced about 11 percent lower than the XT version, making the price-to-performance ratio nearly identical between the two cards. Under-volting both GPUs can improve performance by providing more thermal and power headroom, allowing the cards to maintain higher average clock speeds. The XT model's performance lead is most pronounced in demanding scenarios, such as ray tracing, where it can pull ahead by over 20 percent in specific titles. Ultimately, the choice between the two depends on whether a user prefers a 10 percent lower cost or a 12 percent performance increase.

The Radeon RX 9070 XT features 4,096 cores compared to 3,584 cores in the non-XT model. The RX 9070 XT maintains a 12 percent average performance lead over the RX 9070 at 1440p and 4K.

Both GPUs utilize 16GB of 20Gbps GDDR6 memory on a 256-bit bus with 64MB of Infinity Cache. The RX 9070 XT typically costs about 11 percent more than the non-XT model in the US market.

Under-volting both cards can increase performance by allowing higher sustained clock speeds through improved power and thermal headroom.
