How the Xbox Series X Velocity Architecture works, the "soul" of the console



The launch of Xbox Series X, the new generation console from Microsoft, is still scheduled for the end of this year and, given the strange situation that we are going through a pandemic, the news regarding its characteristics comes to us little by little through the official channels. The company is gradually explaining some details of Xbox Series X such as the sello Optimized for Xbox Series X ’seal or the Smart Delivery functionality.


This week the turn has come to Xbox Velocity Architecture, a technology that Microsoft defines as "the soul of Xbox Series X". In reality, this architecture is based on four components to ensure that the speed of the console reaches levels much faster than the current generation: specifically Microsoft talks about the Xbox Series X having a loading speed from storage 40 times faster than Xbox One.



How each of the four components of Xbox Velocity Architecture works


How do you do this? Well, thanks to the four components we were talking about before: the custom NVME SSD, the Hardware Accelerated Decompression, the New DirectStorage API and the Sampler Feedback Streaming (SFS). This new explanatory article on Xbox Wire explains one by one how each of these four components works and what it does, concluding that cooperating between the four they are capable of instantly loading 100Gb in the video game when it requires it.


  • Custom NVME SSD: The Xbox Series X Integrated SSD is capable of loading 2.4Gb of "raw" data per second. Forty times more than Xbox One. This technology also applies to memory cards that expand the storage of the console.


  • Hardware Accelerated Decompression: This is an algorithm capable of decompressing asset packages twice as fast. Taking this speed into account, Microsoft ensures that 4.8Gb per second can be loaded in the game, one hundred times more than the current generation.


  • New DirectStorage API: Microsoft claims to have redesigned the I / O loading APIs that have been standardized for 30 years, thus virtually eliminating loading times.


  • Sampler Feedback Streaming (SFS): with this component, we have been able to optimize the loads and readings of the game's data so that at all times it achieves an adequate performance that the game requires.



From Microsoft, they explain that the Xbox Velocity Architecture is the answer to the demand of video game developers who, until now, have had to look for tricks to prevent the player from noticing that the game is loading things: elevators, cracks in walls, narrow corridors … All those tricks that give the impression that there are no loading screens have already become very outdated and with the architecture of the Xbox Series X in combination with the potential of the new graphics engines, this will be reduced to practically zero.
