The Xbox Series X Dev Kit is equipped with 40GB of GDDR6 memory

GamerNexus shows what the XDK looks like from the inside

The fact that the new generation of consoles is strong is nothing new after the release of the Xbox Series X and PlayStation 5 a year and a half ago. However, we didn’t know that the most powerful Xbox dev series was even stronger than the last one. console version, as shown by GamerNexus. In possession of the Xbox Series X development kit, Steve Burke shows us that the developer version has 40GB of memory.

The developer package is delivered to developers even before the final release of the console, whatever it is. Apart from game studios, no one can have these. Burke says he bought one online, and the XDK (Xbox Dev Kit) pops up “from time to time.” The development package acquired by GamerNexus was already “banned” from the previous owner, meaning it can’t run games.

Steve did what he did best: opened the electronics and showed the details. After a long struggle to open the developer package and reveal a well-done structure, 40GB of GDDR6 memory is used. There are 10 2GB modules on each side of the motherboard, adding up to more than double the memory in the final consumer version of the Xbox Series X.

The console has 16GB of GDDR6 and this amount of memory is divided into two categories: the former has 10GB of faster memory, providing 560GB / s of bandwidth (14GBbps at 320-bit speed), and the latter 6GB is slower, reaching 336GB / s ( 14 Gbps on 192-bit). The developer-equipped memory runs at 14 Gbps (320-bit) and offers 560 GB / s of bandwidth.

Even the GeForce RTX 3090 Ti, the strongest gaming graphics card on the market, doesn’t have as much memory as it comes with 24GB. Only NVIDIA’s state-of-the-art workstation GPU, the RTX A6000, can bypass this value with its 48GB of memory. For specifications, the Xbox Series X has an AMD APU with 8 Zen 2 cores and an RDNA GPU with 56 computing units.
