Still all rumor on resolutionat target, nothing official. But I've never really agreed with the 10gb number. Does it make sense for 4k to 1080p games? Yeah, but I always thought it would match 1X's 12gb. Too many different RAM targets( 8g, 10gb, 12gb & 16gb). 10gb on Lockhart doesn't make sense unless OS tasks on Lockhart are not the same as SX(2.5gb) or 1X(3gb). So yeah, 12gb+an extra 4gb=16gb for 4K makes more sense.

The rumours state that lockhart has still the fast SSD. And with it even more bandwidth available than the series x which must load the higher rest textures etc
... but well I don't think SSD bandwidth will be that much of a game changer like some state. SSD latency will, but bandwidth .. I don't think so.
It would make sense to reduce the OS footprint. Like recording your sessions. I really don't think this feature is heavily requested on a lower end console. Screenshots, yes but videos ... I really don't think so.
But lets just say it has 7.5 GB available:
- reduces render target (saves bandwidth memory not so much)
- lower texture resolutions (greatly saves bandwidth and memory)
- lower shadow resolution
- maybe no RT (saves memory & bandwidth)
And still only data that needs to be in memory is loaded via SSD. So I really have no problem with the reduced capacity even with xbox one x in mind which had 12 GB. Yes it would not run xbox one x enhanced games because the memory might be missing but this is the low-end console.
If MS is generous they will still increase resolution (e.g. doubling pixel count) to run BC games because the GPU is more than capable of running this things. Even more texture detail should not be a problem like x-enhanced xbox 360 titles. But x-enhanced xbox one games could get a problem, unless they can somehow enforce even older game just to load the higher res textures and get rid of some things no longer needed somehow without patching xbox one games.
But I really don't think that this is needed. They will just straight of run the xbox one game and it will be ok.
Overall the OS might just not need the big memory footprint the xbox one OS needed, because it can load everything fast from the SSD. Even code from DLLs must not be persistent in memory as it can load fast enough from the SSD. Only the real important stuff has to still be in memory.
For the segment Lockhart is focused on price is most important.
