Your issue here is that yu do not understand what the tech is actually being used for, or more so, what kinda tech you need to achieve certain things.
I know what it's being used for. What you don't understand is that pound for pound, dollar for dollar, you will get much more power from the Orion-based PS6 than the handheld. The handheld is devised to be a low power machine, watt for watt, the Orion console can't come close.
Having that as premise, it doesn't make sense to leave the next-gen saturation to the handheld device that is even less powerful than a PS5 in raster, when you have an Orion console that is leaps and bounds more powerful by just being $100 dollars more.
Canis makes sense to exist as a handheld and as a complementary to a moderately priced PS6 home console.
Lets look at this from the two things the PS6 will address. Lets call this device A and device B
A console capable of doing native 1080p-1440p and upscaling that to 4K plugged into a living room TV. This console would run PS6 games at the highest possible fidelity and will offer the overall best experience.
That's not gonna happen with just 30GB of RAM vs 20GB of RAM. You get the best fidelity on PC with everything maxed, but it's not the RAM that takes you there, it's the 500watt GPUs.
You will get the same game with the 20GB PS6 but with less uncompressed audio and texture. New compression techniques will be the new craze.
You won't even need to think of what ifs because even PC GPUs will be conservative when it comes to RAM. Only the $2000 GPUs will have 32GBs.
To ensure that this console can keep doing that for the next 10 years and not become outdated, you need minum, 4Ghz CPU, 3 GHz 56 CU GPU, 160-bit bus, 30GB RAM, which means around 26GB available for devs/games, at least 1TB SSD....etc.
No, you don't need that as a minimum. Canis handheld already exist.
PS6 Pro can exist with 30GB or more for those who want it. Up to Sony. But I think they should do it.
This is your baseline for the next generation. This baseline will cost the consumer around $600-$800. This is device A.
The baseline has to be cheap enough. Sony don't need to absorb unnecessary losses when they can cut the BoM cost by reducing memory components.
The Pro can go bonkers with specs, price doesn't matter.
Now the second thing..
You need a device that can run what device A can run, but instead of targeting lower settings, lower peak framerates, and lower native resolutions. So now you are trying to run games at 360p-540p native and upscale that to 1080p.
The baseline PS6 can also target lower settings just like this low power, low raster, low watt, low bandwidth device.
And you get much more power, raster, path tracing, and pixels pound for pound dollar for dollar in the Orion PS6.
Preferably, primarily used on a 7-9" handheld screen, but giving the option to plug it into a TV. To do this, you need a much smaller GPU, less bandwidth, less RAM, and when you tie all those things together, it will fit into a handheld form factor. This device will cost consumers anywhere betwen $400-$500. This is device B. (to help you with some context... 360p is 16x less than 1440p, some napkin comparison would tell you that the PS6 handheld could technically be about 8-16times weaker than a home console GPU and still be able to handle PS6 games... if they make the right decisions in the right areas).
The handheld is a great idea. But it should not replace the idea of an affordable PS6 console set top box.
This is where you should start making your analysis from.
A "proper" PS6, costs what it costs because that's what it costs to make a proper next-gen console today; you do not cut back on that in such a way that you are releasing an underpowered, incapable machine because you are trying to save a few bucks. The best thing to do is to make two separate products that are in the same family. Hence a home console... and then a handheld. If you do this right, one of them is not holding back the other. You make a product for the people willing to spend no more than $500, and you make a product for the people willing to spend as much as $800.
I am adding this part because I feel I may need to explain everything and trying to avoid that... the right areas are that both PS6 and PS6H are based off the same architecture and have an identical feature set, PS6h will have RAM close to the PS6 in capacity and bandwidth at about a third to half in speed.
The switch has shown that you do not need a 30GB $800 console to sell 100M.
This is the one crucial detail you are ignoring and likely explains why, in all this stuff, you say you talk like the PS6h doesn't exist.
It does, and its for a reason. The PS5 handheld addressing a lower budget, 1080p market, is the sole reason a proper PS6 in the traditional sense can exist in this day and age.
PS6 Pro can exist to fulfill our ultimate PS6 wetdream. But an affordable baseline PS6 should exist before that.
The handheld can't be that "baseline" device because dollar for dollar it doesn't make sense.
