I'm a bit disappointed that AMD might not be targeting the high-end market this time around. I was hoping to see a successor to the RX 7900 XTX that could rival Nvidia's top offerings. But if they can significantly improve ray tracing performance and offer better price-to-performance, I guess that's still a win for consumers.

Thanks for sharing these rumors and specs about the upcoming AMD RDNA 4 Radeon RX 8000 series! A few thoughts:

Launch Timing and Lineup

• Launching in late 2024 (Q3/Q4) seems reasonable, giving AMD time to further refine the architecture.
• Having two main GPUs (Navi 48 and Navi 44) targeting different segments makes sense strategically.

Specs and Technology

• The 256-bit bus with GDDR6 for Navi 48 and 128-bit for Navi 44 aligns with positioning them as higher-end and midrange offerings respectively.
• 3GHz+ clocks on partner cards would be impressive if they can pull it off with good power efficiency.
• Monolithic design on TSMC N4P sounds like a proven approach, leveraging a mature node for cost and yields.

Pricing and Positioning

• Focusing on the midrange around the $400-500 price point is smart. Lots of volume and less competition there.
• AMD needs compelling options to counter the inevitable RTX 4070 Ti Super and whatever else Nvidia releases.

Performance

• If the RX 8800 XT can match the RX 7900 XT and beat a 4070 Ti Super, that would be a very strong showing.
• 10-30% ray tracing uplift over RDNA 3 is decent, but AMD still needs to close the RT gap with Nvidia.

Overall, I'm cautiously optimistic about RDNA 4 based on these rumors. The specs sound reasonable, and the pricing and performance targets make sense. As always, waiting for independent reviews is wise. But I'm excited to see how RDNA 4 turns out and if it can keep AMD competitive in the GPU market through 2024 and beyond.

The rumored specs for Navi 48 and Navi 44 look promising. If AMD can achieve those clock speeds and improve the architecture, we could see some impressive gains over RDNA 3. I'm curious to see how they'll stack up against Nvidia's upcoming RTX 50-series cards.

So there will be no RX 8900 XTX / RX 8900 XT ?

I expect consumer GPU development and performance to be disappointing in the coming years due to a few industry trends:

1. GPU makers are prioritizing AI and data center products over consumer cards, so development resources and advanced fabrication for gaming GPUs is reduced.

2. High demand for AI accelerators is driving up chip fabrication costs, which translates to pricier consumer cards as well.

3. Supply limitations on advanced memory like GDDR7 keeps costs too high for feasible use in mid-range consumer cards in the near future.

On the positive side, growth in advanced memory like HBM for AI purposes may ultimately improve supply and reduce costs enough to reemerge in high-end consumer cards in a few generations.
