Microsoft lists it on a 128-bit bus, with 8GB at 224GB/s and 2GB at 56GB/s. This is system memory (RAM), not the console’s SSD storage.
How the Xbox Series S memory is specified
Microsoft’s Xbox Series S specifications list 10GB of GDDR6 memory across a 128-bit-wide bus. The memory is described in two bandwidth tiers:
- 8GB at 224GB/s
- 2GB at 56GB/s
Those figures describe the console’s memory configuration and bandwidth, not a separate RAM upgrade or a user-adjustable setting.
RAM is different from storage
The Series S also comes with internal NVMe SSD storage, with Microsoft listing 512GB and 1TB configurations. Storage holds installed games and other data; it is separate from the 10GB of memory used while the console runs games and apps.

Microsoft’s cited product specification gives the total memory amount and bandwidth tiers, but does not state how much memory is reserved for the operating system or available to a particular game. The 10GB total therefore should not be presented as a confirmed per-game allocation.
