AMD RDNA4 Architecture Speculation

NVIDIA definitely runs tensor and fp32 ops concurrently, especially now with their tensor cores busy almost 100% of the time (doing upscaling, frame generation, denoising, HDR post processing, and in the future neural rendering).

Latest NVIDIA generations have become exceedingly better at mixing all 3 workloads (tensor+ray+fp32) concurrently, I read somewhere (I can't find the source now) that ray tracing + tensor are the most common concurrent ops, followed by ray tracing + fp32/tensor + fp32.


The way I read this it seams that while the workloads are executed concurrently, they are still not dispatched concurrently (unlike on some other architectures). So some pipes will be underutilized.
 
According to ITHome, who are quoting their own sources now, the Radeon RX 9070 GRE is indeed coming. Presumably, this means another Chinese market exclusive; however, there were instances where AMD brought GRE models to the global market (RX 7900 GRE).

The media have no specs on this graphics card yet, but they assume that this means a 192-bit memory bus and, as a result, a 12GB GDDR6 memory configuration. This sounds a lot like an RX 9070-class GPU, except AMD already has one, and the RX 9060 XT is already confirmed to have a 128-bit memory bus.
 
Just like the RTX 5060 Ti, the Radeon RX 9060 XT will feature two memory configurations of 8GB and 16GB. The difference compared to GeForce is that AMD is sticking to GDDR6 technology and clocks of 20 Gbps.

Based on the most recent information we have from AMD board partners, the RX 9060 XT will launch with 2048 Stream Processors. This is, of course, nothing surprising, because the card was meant to use the Navi 44 GPU, which has half the core count of Navi 48.

We also have an update on clocks, and it looks very interesting. First, a reminder that the RX 7600 XT, the predecessor to the RX 9060 XT, featuring the Navi 33 XT GPU, had a game clock of 2470 MHz and a boost clock of 2755 MHz. The RDNA4 update will have much higher clocks. According to our information, the RX 9060 XT will ship with a 2620 MHz game clock and a 3230 MHz boost clock. But that’s not all, we also learned that some OC variants will have a 3.3 GHz boost.
 
Radeon RX 9060 XT should be like 5 % slower than GeForce RTX 5060 Ti. Why should it be $130 cheaper? Also, there's just $50 difference between Radeon RX 9070 XT and Radeon RX 9070. Why should be the Radeon RX 9070 GRE $150 cheaper? I'd expect $499 for the GRE (maybe $479 if Su's in a good mood), $399 for XT 16GB and $349 for XT 8GB.

That would be 4 cards in a $200 range. And only $100 between the 9070 GRE, “regular” and XT. Thats a tight grouping.
 
Approximately (+/- $30) $449 9070 GRE, $349 9060 XT 16GB, $319 9060 XT 8GB, and $269 9060 is my guess if tariffs weren't a factor. With tariffs...
