The one thing I don't believe is the 160W target. Since when Sony is interested into low power consumption in their consoles at the cost of performance? not when low power modes is definitely possible on PS6 too so that would satisfy their recent californian ideology.
PS5 Pro can consume up to 250W in some games and they didn't get sued by anybody because of this.
You just don't get it. It's not about being environmentally friendly. It's about having lower power draws in datacenters.
I mod the /r/xCloud subreddit. xCloud engineers hang out there getting feedback. xCloud runs on Series S profiles on custom Series X server blades. Everyone had assumed they ran Series S profiles in order to double capacity by running two Series S instances per X APU, since X APU could run four instances of One S.
But back in April, one of the main engineers confirmed they only run one single instance of Series S per X APU. That it wasn't possible to run two per X APU since Series S games were coded with full CPU cores availability.
So the main reason they ran Series S profiles was because xCloud is limited to 1080/60 currently. They don't need 4k/60 streaming on mobile. 2nd biggest reason is that electricity and cooling costs are their biggest expense in a datacenter.
Sony wants to expand PS6 streaming to other devices or they're going to be left behind in the future. But they also want to keep costs down, you do that by having 160 watt 4k/60 mode in the hardware that will be used as custom chips for cloud streaming. And the power draw can be lowered even more for 1080/60, thus the low power mode
Sony is trying to find the right balance.
MS will be using Magnus in the Cloud also, but MS will likely keep it to 1080/60 or 1080/120 profiles for Gamepass streaming. Then they're working on Cloud Only tiers that will offer better streaming quality to 4k/120. But that will be additional costs. Either an addon Fee, or Ultimate pricing goes higher.
Sony can't make PS+ Premium pricing higher unless they start including Day One games.
So the power draws are all about streaming costs.
