Xbox 720 Memory System Detailed? [RUMOR]
A schematic allegedly outlining the details of how the next Xbox will use its various types of memory has surfaced, and gives hardware buffs a better understanding of what to expect from Microsoft's next-gen console.
The "Durango" will feature two types of memory, 8GB of DRAM, and 32MB of ESRAM, according to VGLeaks. As you'd expect based on those numbers, the DRAM does most of the heavy lifting, supporting the CPU, GPU, Display, Audio, etc. The DRAM can push a read/write bandwidth of 68GB/second, across all of the console's processing functions.
Meanwhile, the ESRAM augnments the GPU and move engines to reduce latency. At a 102GB/second bandwidth, it a little bit of extra memory will go a long way to keep things running smoothly at high framerates.
VGLeaks has posted a series of schematics detailing rumored hardware architecture and specs for the Xbox 720, including a map of the system's supposed dual CPU system earlier this month. While none of this information is anywhere near confirmed, the language of their most recent report suggests this schematic may be the visualized culmination of "multiples [sic] replies and discussions."
For most gamers, this level of hardware speculation seems like random numbers and overly granular conjecture, but for those inclined to truly compare the merits of Xbox 720 and the PS4, these subtle difference make all the difference. It's not just about how much memory you've got, but how you use it.
