Sorry, I'm late, slept in today xD
CPU: Jaguar is disappointing, but it sounds like MS has worked some "magic" to allow it to not be a bottleneck in most games. A switch to Direct3D 12, which allows CPU tasks to be offloaded to the GPU, which apparently means up to 50% lower CPU overhead.
GPU: It sounds like a beast for a console GPU. Basically mid-tier by PC standards, but thanks to optimization and some architectural "magic", it sounds like it's roughly equivalent to a significantly more expensive 1070 or Fury GPU
Memory: 12 GB at 326GB/s sounds like plenty. 3 more GB available to developers than they get on XB1/PS4 and 2.5 GB more than they get on PS4 Pro.
Hard Drive: 1 TB is kind of disappointing considering 2 TB drives are only like $18 more nowadays, but it is 50% faster which means loading times for Scorpio enhanced games will be the same as XB1 games, and faster for XB1/360 backwards compat games.
Size: Based on the size of the motherboard and compactness of the cooling solution, it seems like it will be smaller than PS4 Pro, which is good, maybe even close in size to XB1 S.
Cooling: Vapor chamber cooling, what's not to like. Scorpio should be a good bit quieter than PS4 Pro (which is as loud as the launch 360 when playing Pro enhanced titles).
Forza tech demo: Basically Forza 6 Apex running on Scorpio. At Xbox One equivalent settings (basically medium), it runs at 4K 60fps with 66% GPU utilization. At ultra settings, it ran at 4K 60fps with 88% GPU utilization, and I assume this demo was running on the current XDK, which only enables the use of about 80% of Scorpio's power (full system will be unlocked in the June XDK supposedly. All of that means that native 4K should indeed be possible in 900p and 1080p XB1 titles. Not only that, it sounds like we will get other graphical enhancements besides the bump in resolution. Whereas most XB1/PS4 games run at PC medium equivalent settings, we should see some Scorpio games that run at PC high settings, and first party games might even hit PC ultra (like the Forza 6 tech demo is able to).
Price: Because it uses Jaguar I do think $400 is possible, especially if MS is willing to sell at a bit of a loss in exchange for more adopters (which they were willing to do at one point in time, because more adopters means more peole buying games, accessories, and XBL subs, all things that MS makes a profit on). I can't see it costing more than $450, MS isn't crazy, they know Sony will drop Pro to $350 this Holiday.
