That's hard to guess in advance, but it'll certainly be many millions.How many units over say 5 year period?
Because what they're imo doing here is actually competing with mainstream OEM and DIY gaming PCs, not PS6.
And most of those gaming PCs they're competing with will be either slower, more VRAM-limited, or much more expensive.
Think about it: Even at a price of $999, $1099 or even $1199, they'd still seriously undercut most new gaming PCs of similar performance in price.
If you can get an entire Xbox PC for the price of a single 5080/6080, a lot of people will be going XbPC.
I mean, good luck getting a decent mobo, PSU, NVMe SSD, 12C Zen6, 32GB RAM and 5080-class GPU (and a legal Win11 license) for about $1K total in 2027.
Nevermind that this Xbox PC will have the advantage of a shared memory pool, so the GPU might have more than 16-18 GB at its disposal in games that need it.
With Xbox PC, MS can also ask a much higher price for the same hardware than they could for a "pure" console, and still be hella price-competitive vs. "normal" PCs.
In console-only space, they'd have a hard time against PS6, due to lack of exclusives and lack of graphics edge. But in PC space, they might be competing against PCs with 8C + 8-12GB gfx cards on price, yet against 12C + 5080+ on performance.
In fact, that might be one of the reasons AMD killed AT1:
They knew of MS' plans, and knew almost nobody would buy a 48WGP AMD dGPU at $1k+ anymore if - in addition to potentially strong competition from 6070Ti/6080 - people could get an entire XboxPC with a 34WGP GPU and large shared memory pool for the same money.
