Xbox One X – 15 New Things You Need To Know Before You Buy Microsoft’s Next Big Console

12 GB GDDR5 RAM

The Xbox One had roughly 8 GB GDDR3 RAM with a bandwidth of 68.3 GB/s. Another 32 MB of ESRAM was included which brought its own bandwidth of 109 GB/s. The major caveat with the Xbox One was that only 5 GB of RAM plus ESRAM was available for games. The Xbox One X, meanwhile, has a whopping 12 GB of GDDR5 RAM, of which 9 GB is for games, with a memory bandwidth of 326 GB/s. Whichever way you slice, that’s a ton of memory and bandwidth to play with.
