    I think the honest answer is; it depends on what the developers want to do.
    If they want high frame rate; they will just reduce the graphics settings low enough such that both are running their maximum clocks.

    Of course. By itself, it's a good solution. Compared to XSX, not so much.

    Isn't it the saying "what's good for the goose is good for the gander"?

    none specific to PS5 announced yet. But they should have access to VRS and SFS type technologies. Other than that, there's no possible way that SSD could be a bottleneck on any game. So, I suppose there can be some changeson how engines work within the limits of the available memory.

    To be honest I am still confused with the explanation.

    Even on a pc cpu, with something like cool'n quiet for AMD, I believe your best option for saving power and reducing heat is to race to sleep. You want to use SIMD instructions as much as you can, get your work done 4x faster and then put the processor back into a low frequency or "off" state. Obviously if your frame rate is uncapped, you'll just be working all of the time, but if you cap your frame rate you'll save a lot of power in less demanding frames or engine ticks.

    I don't know how idle states work on Xbox One X or Series X to know if they do this, or if they just waste power by sitting at max clock all the time. I'm not sure that Sony's strategy of spreading out work really makes sense from a power saving perspective, but it does seem like there are wins in terms of increasing average performance.

    Like will it even ship in a case or just bare bone parts to be put on a desk?

    There are at least 2 systems:

    - Smartshift detects idle states on the CPU and give any available power to the GPU, so apparently based on load (not power consumption), but it's just from CPU to GPU and Smartshift doesn't modify the clocks.
    - The variable clocks system detects loads of both CPU and GPU and set the clocks to keep the load at <=100% in total.

    They haven't said that it has a case, so it must not have one. No case confirmed.

    They have shown the case already, it's a giant V

    That's for DevKits and Cats only.

    I think no-one's denying that either. It is a smart solution for the situation they are in (36CU limit).

    Oh yes, certainly sometime somewhere that will come to light. If it matters is another thing though, they will need to come with games that appeal, aslong it wont be a PS3 in that regard, it doesnt matter if it's 9TF or 10TF or somewhere between. If it's another PS2, it's a buy for me no matter what.

    What PS5 is doing sounds exactly like AMD Smartshift. It has a controller that adjusts power to the CPU or GPU based on workloads so they can achieve higher clocks.

    It's a smart solution in any situation. They way designed it there don't appear to be any drawbacks, just benefits over not having it.

    They more of had to, there are no drawbacks because otherwise, the clocks would not even be 2ghz for the GPU and 3 for the CPU. Therefore it has no drawbacks for Sony's PS5.

    I agree and that's my point... even if it's 9.2 or whatever, just get it over with. It not going to impact sales. It's a miniscule percentage of people that would ever be aware. Previous investment in a given ecosystem is going to hold people in their existing camps. So why not just share openly with the people that care? They have nothing to be embarrassed about. It's going to have great games at the end of the day and that's all that will matter.

    It's a good solution in a power or thermally constrained environment. That's why it was designed for laptops, but it does make sense in the console space. The only downside is whether devs that are trying to push the limits of the system find some dynamism in the performance annoying to work around. That of course would really come down to individual developers and how much variability the devs really notice. It sounds like any potential worst case would see clocks drop in the single digits, so it honestly shouldn't be too hard for them to work with.
