That's definitely a school boy error on Xbox/Microsofts part. Why handicap your system like that, especially when it's went on to be the best seller for them so far this gen.Yeah. The One X has 12GB of RAM with 326MB/s bandwidth. The Series S has 10GB, split into 2 pools, a 8GB pool with bandwidth of 224GB/s. The remaining pool of 2GB is so slow it's only really suitable for background tasks and the OS, because the bandwidth is 56GB/s.
