Not sure about RX 9060 XT but RX 9070 XT are selling very well by amd's standards.
RX 9070 XT is above MSRP because people are buying it well. Look at RX 9060 XT 16GB it's even right now much sooner already at its msrp people probably are not buying it as well becouse of poor p/p ratio. You have 16GB of VRAM but weak performance in generel even for it's price and RTX 5060 Ti 16GB is similar story.
In this generation
50 Class gpus are weak RTX 5050 same as RTX 4060 for same price waste of two years zero gains
60 Class gpus are weak RTX 5060 Ti 16GB, RX 9060 XT 16GB weak performance for the money
70 Class gpus are only average RTX 5070 12GB, RX 9070 XT, RX 9070 only average nothing more (RTX 5070 Ti is the worst of those three)
80 Class gpus are weak RTX 5080 performance gain is extremely terrible
90 Class gpus are weak RTX 5090 average perfomance jump but price.... It's not a gaming gpu more like titan crap or something like that where you are paying for name not for actual performance.
50 Class: Will sell to a fault in emerging countries, and an eventual slot power 75W model has a nice niche all to itself in the HTPC/SFF market. AMD seems uninterested in the low-end dGPU segment, we haven't had anything here since the 6500 XT.
60 Class: Prebuilts alone cover this segment. It will sell an inordinate amount through DIY, and the 9060 XT needs better street pricing to make an impression. Buyers of 60 class GPUs are generally value sensitive and don't hesitate on having the absolute latest technology available to them, which should open this market to options the RX 6/7600 series, or the RTX 4060 duo of cards.
70 Class: The only place where AMD poses any meaningful competition. The 9070 is IMHO a better purchase than the 5070, and the 5070 Ti/9070 XT trade blows to an equal extent: customer has to decide what they prefer and what works better for their use case, with street pricing taken into account.
80 Class: This is where price concerns go out of the window, as AMD offers no GPUs worthy of being compared to the 80 Class this generation. It's a poor value proposition, most gamers would be better serviced by the RTX 5070 Ti or 9070 XT GPUs on a cost proposition, but the fact remains the RTX 5080 has an uncontested performance lead if price isn't taken into account. If AMD is smart, they'll position the Pro R9700 at the $1500 level, cheaper than the 5090 and certainly far less powerful, but with enough video memory to make a dent in the applications that don't run well on the 9070 XT due to its VRAM capacity (which are few, but exist). If AMD prices it like the RTX 5090, unless the application is validated/certified exclusively on Radeon Pro platform by the ISV or there is a mortal need for ECC memory support, it's an inferior product when compared to the RTX 5090 in every possible manner, regardless of use case.
90 Class: At 2x+ the competition's top generational performance... that's a wrap, they can charge practically whatever by this point. The RTX 5090 has no equal, and sets the minimum benchmark the the UDNA architecture has to beat by late 2026/early 2027.
