My gut tells me that was just a cookie cutter reply.
If I remember correctly, one of the things the AMD executives said last September as they made it official they had killed high end for RDNA 4 at least, was they had pivoted the entire team doing FSR to AI (upscaling and frame gen) around January of 2024 and one of the reasons was to boost battery life on handhelds.
So unless AMD is going to outright stop manufacturing and selling RDNA 3 and 3.5 based APUs, what they are saying currently makes no sense. Unless they were not certain what they were doing when they killed off high-end RDNA 4 last year. The exec also talked about AMD having something for enthusiasts that will use chiplet technology. While that doesn't mean RDNA 3, the easy win would be FSR 4 on the chiplet design SKUs of RDNA 3. That is unless they are planning to release UDNA this year or a dual chip version of the RX 9070 XT like they did for R9 295X2 which both seem highly unlikely.
The entire marketing or upselling people with RDNA 3 to buying RDNA 4 that people online are saying also makes zero sense to me. I own a RX 7900 XTX and game at 4K. Outside of ray tracing (and there is really only a small number of games with there is a meaningful improvement i.e. from a display refresh rate standpoint not fps number) there is no benefit gained from replacing the RX 7900 XTX with the RX 9070 XT. FSR 4 simply isn't enough of a reason and not at current prices or even at MSRP. Put it this way, I spend $1,200 on my Sapphire Nitro+ RX 7900 XTX. Why would I spend bother selling (for at best $800 bast on current prices on eBay) to then spend $800-$850 to get on average 10% less gaming performance on a RX 9070 XT just for FSR 4?
Even when I think about the RX 6900 XT I have in my Threadripper workstation, I would still just wait for whatever AMD do with UDNA or whatever the RX 1090XT(X) is based on (if AMD even return to the high end in the next gen of GPUs) before buying a new AMD GPU. I would then swap out the RX 6900 XT RX 7900 XTX. I have a RTX 2080ti in the Threadripper build as well. So, it's not like I'm chasing the latest and greatest from a professional AI/ML standpoint. The value proposition of the RX 9070 XT just isn't there for me not to just wait or even jump to team green and buy a used RTX 4090 if I really want the extra gaming and AI performance.
If all I had were the RX 6900 XT (or RX 7800 XT) and my Radeon VII which is in a box somewhere, then I could see a reason to go for the RX 9070 XT but not from a RX 7900 XTX or RX 7900 XT.
