if theres one thing i learned from actually putting a PC together, its that you can not actually compare the two. consoles games are always better optimized, and with PC you always have to ask yourself if there is a slightly better part you could get for a few bucks more. the ecosystems are so different that it really is impossible to do a proper spec/price comparison.

Well the price of Memory chips is rising again since last summer instead of dropping because production is running at full capacity and still not able to fully meet demand. All other parts will probably not go down by much until then, so, it could actually end up costing more by release of scorpio intead of being cheaper.

Also, a 390X would be more on point with the calculating power of the Scorpio than a 480X. Or at least taking an OCed one to make up the difference instead of just picking the cheapest 480X in the list.

I agree. But the rest of the game needs memory too, and my guess is that most AAA games are going to use between 4 GB and 6 GB for the GPU. Allocating less than 2 GB for the CPU just seems so little.

Yeah I have to agree with this.  The optimisations on console games is the really big plus.  Developers know exactly what people will have and that makes it much easier on them. 

No more than 499 $ by the end of the year. Which is why I'm certain Scorpio will launch for 399 $ or less.

I do not think they are targetting PC gamers. Xbone was released at 500$ and without Kinect 400$. I cannot see them selling Scorpio considering its specs less than 450$. I will not be surprised if it is 500$

Also we need to wait and see the performance of Scorpio with all the games. Comparing with it Forza6 alone it is impossible to tell which TBH is very well optimized for even Xbone.

No.

Microsoft has freed up the CPU from having to do some processing tasks, the CPU isn't dramatically faster outside of general clockspeed boosts and latency reductions (Likely to counter the higher latency GDDR5 memory and the removal of eSRAM.)
It's still Jaguar or a derivative. It's still a heap of low-end shit.

Remember... It's based on AMD's Cat cores, it's meant to compete against Intel Atom, ARM etc'. It's still got nothing on Intel Core or Ryzen, heck even Bulldozer based CPU's.

PC doesn't need to worry about any of that, because the PC doesn't tend to use Tablet-levels of CPU performance for gaming and thus need to make ends meet with other 'unique' approaches.

As for Direct X 12. You need to keep in mind the entire API hasn't been moved onto the GPU. Only a part of it in the Command Processor.
And the gains from the improvements done on Scorpio on that front is most certainly going to be very game-engine and game dependent. It will not be applicable to all titles.

If you think this somehow transforms Scorpio into a High-End PC, then you are kidding yourself. Scorpio can punch above it's weight, sure.

Switch is using nVidia hardware. Not AMD. Microsoft has nothing to do with it.

The 12GB DDR3 is a bad idea anyway. And can actually reduce performance due to the missmatched capacities. Better off with 8GB or 16GB.
8GB of System memory is enough for PC gaming at the moment... Even if you had 128GB of Ram, you still will not earn a single extra framerate if the game is still only using 6GB or less (Plus a few GB for Windows/other tasks) of memory.

The other caveat is that the PC doesn't reserve 4GB for the OS and background tasks. Windows will be happy with about 1.5GB for itself.

You could shave a good chunk off that build anyway by going with the FX 6300, ditching the optical disk (No one uses them) and having 2x4GB Ram sticks.

To be fair, Forza 6 is also extremely well optimized on PC.  The engine is good at what it does.

Scorpio will perform sooo much better than a PC with similar specs, so why to bother...

I dont think you need that extra 4gb of ram, since the GPU has its own 4gb, that it doesnt share already.

It would be better to get two cheaper dual channel pair of ram of 4gb each (4gbx2=8gb total).

And minor stuff like that, you could probably get prices down by like 50$.

500$ PC with overclocking the GPU should get close to a Xbox Scorpio.

there is no DDR5 memory out yet. The Standard for it is only about to be set even.

What you mean is GDDR5. That G stands for Graphics and is derived of DDR3 memory. It comes with a much larger Bandwith, which graphic card needs, but at the costs of much longer latencies (making it unsuitable for CPU RAM) and much more power consumtion.

The build is using DDR3 because it's the only kind of memory the Bulldozer Chip can handle anyway. More modern processors, like Ryzen, would use DDR4 memory.

As for the Blu-Ray 4K drive, there ain't one on the market yet right now as far as I know. Which is why a Blu-Ray writer is installed instead, and the extra costs of the writing heads make up a bit for the 4K read capacity.

499$ is also what I expect at launch, but will drop soon because it will not sell. Too few good exclusives and having such a big price compared to the PS4 pro will force the Scorpio to drop in price fast.
