The developer kit for the Xbox Series X console reveals how much GDDR6 memory game producers have received. 2x more than Xbox Series X.

This fall, it’s been two years since the premiere of the Xbox Series X console, known to be the most powerful console you can buy today. As we already know from the official specs, the Microsoft device offers a total of 16 GB of GDDR6 memory, of which 10 GB uses the 320-bit bus, which translates to 560 GB/s bandwidth. The remaining 6 GB uses a 192-bit bus and a bandwidth of 192 GB/s. So far, no specific information has appeared confirming what the console’s configuration will look like in the case of the so-called devkit, a special variant of game developers. However, material made by Gamers Nexus appeared on the web, confirming the use of much more memory. The decision seems obvious, but it is unfortunate that the final product in stores does not offer more VRAM.

Images showing the inside of the developer version of the Xbox Series X console appeared on the Web.Game producers have received much more GDDR6 memory, that is, 40 GB.

It turns out that the Xbox Series X controller has exactly 40 GB of Samsung GDDR6 memory soldered to the motherboard. All bones are labeled with K4ZAF325BM-HC14, which means they have an effective clock of 14 Gbps and a density of 16 Gbps (each cube is 2GB). Microsoft placed 10 bones of GDDR6 on either side of the motherboard. All memory runs on a 320-bit bus, offering a bandwidth of 560 GB/s. As you can see, the console hardware does not divide memory into faster and slower, as in the consumer version of the Xbox Series X.

Why did Microsoft decide to put up to 40 GB of GDDR6 memory? The biggest memory buffer by default is to help game developers debug new games while using uncompressed textures, even before the actual optimization process. Interestingly, the cooling system also looks extensive – everything looks like a large steam room, although there are copper heat pipes connected to an aluminum heat sink. An interesting project, but it’s a pity that the final product doesn’t provide even a few gigabytes of memory more.
