Xbox Project Scarlett, release in Holiday 2020

• AMD's Zen 2 CPU + Navi Graphics (previous leak suggest 8 core CPU that is quite low power)
• GDDR6 memory (up to 22GB 352bit bus)
• Fast NVMe SSD also used for virtual RAM
• Will have ray tracing (most probably it is marketing only!)
• 8K support (marketing only!), 1080 120fps and even may be 4k 120fps.
• Streaming services will be a big part of the console
• You won't be being able to resell games you bough
• Big role of rented games, can be that most games will be provided on subscription/rental scheme only
• Microsoft don’t have any plans for VR support, SOny also likely will drop their headset support

From the start consoles will be extremely underpowered compared to most good PCs, only advantage will be more RAM available for GPU. So if you intend to play new games look no less than 11GB for your next GPU and it'll be ok.

So, as we can see - it will be quite weak. SSD most probably will be QLC to maximally save on costs.

4GB now required for dashboard and stuff, huh. Quality of modern developers.

At peak it will consume 250 Watts and it is extremely low, as same 3700X overclocked consumes around 150 Watts, same is true for graphical system. Most probably here we will see first time same approach with notebooks - software will throttle things and all real performance will be restricted by thermal package and not real hardware limits.
