Theory/Prediction: Sony is about to reveal a Portable PS4

1. The NUC is likely based on a diferent pricing model than a PS4 Portable. Retail price is most likely somewhere between 2x - 3x the cost of components, packaging, and shipping. Teardowns in the months to come will give a clearer picture.

Chip companies like Intel, AMD, nVidia and so on tend to try to go for 60% profit margin at a minimum. Ironically... That was also the rough profit margin on Ryzen which has pushed AMD into the green.

Now semi-custom designs like what is featured in consoles tends to have a different pricing model thanks to various agreements.

3. The Ryzen Mobile information in Permalite's link are for Raven Ridge, which is 14nm. PS4 Portable would have to be based on 7nm which see improved performance and TDP, along with a smaller die, and more cost reduction. It is the best indication of where we sit with AMD based X86 and Radeon tech for a mobile platform.

Hence why I stipulated AMD's "current" technology. ;)

We are closer to a PS4 Portable than some here are thinking. I see a lot of people looking at current desktop components as a barometer, but the PS4 does not use desktop parts. I also see people saying that PSP and PS Vita fell short of PS2 and PS3. You have to remember PS2 and PS3 were much different beasts than PS4. PS2 and PS3 went toe to toe with high end PC's on release. PS4 was using a weak mobile CPU and a mid range GPU on release.

In multiple different aspects, mobile technology has even surpassed the Playstation 4, especially in regards to the CPU.

Dismissing price is short sighted. Not only because price is a major factor in whether Sony pulls the trigger on this but because it aint going to be cheap. And there is no evidence that a portable PS4 is going to expand their market.

I dunno... Is a Playstation 4 portable possible right now? Shit yes.
Is a Playstation 4 portable affordable right now? That's up for debate.

The 2500U uses like ~25-26 watts in laptop systems, when playing games.

 

I think you are missing the point. The 2500U's CPU is still vastly superior to what is in the Playstation 4. It can be scaled back farther.

Plus the TDP is configurable, it can come under 25-26w, OEM's can implement the chip in different ways with different power states and voltage scaling to reduce power consumption. Plus better binning also helps.

If it was die-shrunk to 7nm, and ran PS4 games at 720p, do you think it would be able to do so?
And would people want a portable that played PS4 games @720p?

Even a drop to "12nm" (If we can call it that) would bring significant gains.

720P needs to die.

JRPGfan said:

A 70-80 mm² 2500U inside a portable *might* be able to run PS4 games (8threads ~1.2 Tflops) at 720p.

Here we go again... You clearly don't understand flops or how it's presented.
The number of flops is irrelevant. I say it again... Irrelevant.

The number of threads is also irrelevant.

Not sure what memory solution would be possible, to allow this though (but again if your running 720p instead of 1080p, memory bandwidth usage isnt nearly as high).

The Playstation 4's GPU is old, slow and inefficient.
You do not need the same amount of Bandwidth to achieve the same result.
