Very difficult to fit 300W into a reasonable console BOM, or physical size, or noise figures. There is an exponential cost when going significantly above 200W. It's about the SoC power density starting to require expensive stuff.Do we have ideas about the cooling solution? If next-gen consoles have 250W or even 300W cooling solution with roughly the same BOM as current-gen consoles, then a lot of things can be eased such as frequency of SOC and power constraint.
This seems to confirm sony asked for some modifications to the silicon for this, otherwise this would be a simple pcie4 plus software. Or an external ssd controller, or on their southbridge, all of which wouldn't require any involvement from AMD.Reporter: I do feel like a lot of what we saw in the PlayStation 5 hinted at a lot of things you guys were working on. A big thing for them was no loading of levels. Was there anything in particular that could allow you to bring that to the PC market? PCI Express 4?
Su: PCIe 4 definitely helps. Things that Sony are doing, they’ve been very specific on their proprietary technologies.
Optimizations which sony asked to help ray tracing, and most definitely no dedicated RT silicon?Reporter: Given that Sony has already announced ray tracing as part of the PlayStation 5, can you tell us if that’s a Sony optimization, or part of RDNA?
Su: So we certainly have done very specific optimizations for Sony. They are a deep customer for us on semi-custom products. There are optimizations there. However, we view ray tracing as a very important element across the portfolio. So we’ll have ray tracing a number of other places... Look at that, you got me to say more about ray tracing!
David Wang, senior vice president of engineering at AMD: We started our RDNA development before the Sony engagement. RDNA is a revolutionary architecture; it’s also very flexible. So it can be optimized [inaudible].
Reporter: So it’s like an FPGA.
Su: I wouldn’t exactly say that.

They seems to imply the new arch is flexible enough not to need separate compute units for RT workload.
I'm overthinking it but the choice of words is interesting when amd talks about their clients, hinting at the scope of the alterations:Optimizations can be anything at this point. Sony/AMD could have retooled a certain amount of CUs (8, 10, 12, etc.) to only handled RT functionality only. Got rid of any logic fat that would have dragged RT performance down, and added any logic more purposeful or suitable for RT. So in many ways its still bespoke dedicated RT silicon.
I'm overthinking it but the choice of words is interesting when amd talks about their clients, hinting at the scope of the alterations:
1. Optimizations
2. Customizations
3. Proprietary technology
This is something I've raised when talking about customisation. There could be a lot of work to support PS4 BC.There's tweaks for backwards compatibility with the PS4 as well. A decent chunk of the ISA for GFX10 has moved to line up with the PS4's generation, but there are gaps.
In an interview at E3 last year Phil Spencer specifically mentioned ray tracing when talking about future things they were working on with their platform team."So we’ll have ray tracing a number of other places... Look at that, you got me to say more about ray tracing!"
In my mind Lisa Su basically said between the lines is that MS console will have RT...
Yea, the trouble is no one knows what it actually means when that is said, much like PS5 hardware RT.In an interview at E3 last year Phil Spencer specifically mentioned ray tracing when talking about future things they were working on with their platform team.
Surprised i haven't seen much discussion about that since that is the kind of nugget that usually get forums and blogs talking.
not too much to say unless we know how it performs while ray tracing.In an interview at E3 last year Phil Spencer specifically mentioned ray tracing when talking about future things they were working on with their platform team.

This is something I've raised when talking about customisation. There could be a lot of work to support PS4 BC.
Even if it was straight GCN if some instructions where removed or behaved differently, it could potentially needed more work than people assume. Their software stack isn't as abstracted as Xbox.

What leads you to this line of thinking?For the most part, the GPU should be mostly a plug-and-play situation towards BC
Don't remember thatOld news
2014:
The Xbox One could one day make use of a powerful rendering technique called "real-time ray-tracing," an advanced system used to achieve photorealistic lighting effects. Microsoft Studios executive Phil Spencer has confirmed that internal tests are already underway.
