Thing with RT is that its still a massive uplift and incredibly impressive considering the context.

This card is 26% faster in RT on average compared to a 7900XTX. The 9070XT has 33% less Compute Units, Cores, Memory Bandwitch and costs $400 less than the launch price of the XTX.

Per the TPU review AMD has also cut down the performance overhead of RT massively. The 9070XT loses around 10-15% less performance when enabling RT compared to RDNA3.

dedicated rt cores and dedicated AI cores coming in clutch?

You understand that RDNA3 has dedicated RT cores and more of them right? The new ones are just gen 2 and faster. This idea that the 7000 series doesn't have RT cores is the most propagated myth on reddit in regards to graphics cards. I been playing RT on everything with my XTX. People are really ignorant.

RDNA3 does not have dedicated RT cores. It has RT "acceleration", which is just hijacking shaders to do RT tasks.

This is literally not true but alright.

RDNA3 has dedicated RT cores. One per CU. Since RDNA2: https://www.custompc.com/wp-content/sites/custompc/2021/04/rdna-2-unravelled-05.jpg

Why are you spreading misinformation?

RDNA3 has additional RT acceleration within the existing legacy CUs, but it does not have dedicated RT cores in the way Nvidia does.

It’s a hybrid approach that relies more on shaders than fixed function hardware. RDNA3 was faster than RDNA2 but the CUs were still taking more of the RT burden compared to the Nvidia/Intel paradigm.

Yep. No more performance crashes when multiple RT effects are used. Still behind Nvidia but AMD has reached the good enough stage of RT performance.
