Xbox Series S Hitting VRAM Limits, 8 GB is the Magic Number
Microsoft launched two flavors of its Xbox Series console back in November of 2020 - a more expensive and powerful "X" model appealing to hardcore enthusiasts arrived alongside an entry-level/budget friendly "S" system that featured lesser hardware specifications. The current generation Xbox consoles share the same custom AMD 8-core Zen 2 processor, albeit with different clock configurations, but the key divergence lies in Microsoft's choice of graphical hardware. The Series X packs an AMD "Scarlett" graphics processor with access to 16 GB of VRAM, while the Series S makes do with only 8 GB of high speed video memory with its "Lockhart" GPU.
Games studios have historically struggled to optimize their projects for the step down Xbox model - with software engineers complaining about memory allocation issues thanks to a smaller pool of VRAM - the Series S CPU and GPU have to fight over a total of 10 GB GDDR6 system memory. Microsoft listened to this feedback and made necessary changes last year - an updated SDK was released and a video briefing explained: "Hundreds of additional megabytes of memory are now available to Xbox Series S developers...This gives developers more control over memory, which can improve graphics performance in memory-constrained conditions."
