Oops. I'm going to buy another PS4...................................................................................................................................................................................?

You comparing 32FP performance to 16FP.  It a common mistake since mobile apu advitise there 16FP performance while video cards/consoles almost always list there 32FP performance.

The Nvidia Tegra X1 FP32 performance is 512 GigaFlops.  less then half of the XB1 and PS4.  

That's the K1 in the 2014 Nvidia Shield Tablet, the X1 was released at CES 2015 and is the chip in the Nvidia Android TV box.

Nvidia showed two X1's running in a self driving car system, with a total power of 2.3 Teraflops, which is more then the PS4.

Imagine if they used that for the PS4.5 they could make it 10x smaller then the current PS4.

I love the sound of technical stuff, but it hurts my head. Can't wait to see how this goes over. Expect reasonable trade ins.

Is there somewhere a 'video; didn't watch'? I'm not going to watch a stupid video for information I could read in a minute or so if there was a written version.

Give it time, RAM requirements will sky rocket soon. As SSD prices fall larger files will start to become more prevalent. You have to have super fast storage in tandem with that amount of RAM, and once the market hss a high enough concentration of super fast storage, you will see this take effect.

8GB is on the very low end at this point. 16GB is pretty much a necessity if you want 4K and multi-tasking. 32GB would be overkill, but it would not be a generational leap. That is why we are seeing these moves from Sony, Microsoft, and Nintendo. There is tech that is worth upgrading to, but it is not enough to move from one platform to another. Thus these spec 2 and possibly spec 3 and 4 platforms will happen.

If the "mainstream-pc" with a GTX 970 or R9 390 is already 200-250% more powerful then the PS4 then how will it survive until 2024?

tsk tsk... its so sad to see so many hoopla over nothing.

remember the psp?
psp 1000
psp 2000
psp 3000

psp 3000 had more ram or something and what not... did anyone take advantage that it was better and released a game that the psp 1000 couldnt run?... yeah... nope.. only nintendo would be that dumb to allow that shyet to happen.

so, to everyone going bananas, take a deep breath and chillax

No read the first the pargraph of the article you posted.

"two Tegra X1 Chips, for an impressive total of upto 2.3 TeraFlops of compute power on FP16."

So 2.3/2 = 1.15 at FP16.  You need to divde again by 2 to get the FP32 performance which is 575 which basically what I said.  The PS4 is still more then double the performance at FP32.

PS4 will stay relevant through these tiered upgrades until a true generational leap can take place.

This PS4K will easily be as powerful as the HD7970 which had ~4TF of performance. It should also move to 16GB of RAM. 

With those stats, PS4 Spec 2 will hold its own with the big boys for another 3 - 4 years. Then a PS4 Spec 3 should take its place until the PS5 is released. 

The original PS4 will continue to see support throughout the entire life cycle, as it is more than capable of continuing to output 900p/30fps games  that are closer to the 1440p and 4K of the Spec 2 & 3 PS4's than the PS3/360 versions where in comparison to PS4/XBO titles. This will be a lot easier task than when devs where building for PS3/PS4/360/XBO/PC, as the tech between PS4 & XBO's upgrades will be nearly identical compared to the techs of those platforms.
