PC architecture is different. It is segmented. If you have a PC with 16GB of System RAM and an 8GB GPU, the game cannot simply use your system RAM for textures without a severe performance penalty. The PCIe bus (the bridge between CPU and GPU) is fast, but it is not as fast as the direct access the console GPU has to its memory.
From the broken streets of Cyberpunk 2077 to the dense jungles of The Last of Us Part I , a troubling trend emerged: games that launched with severe stuttering on "recommended" hardware were being fixed by "8GB Patches." But these weren't patches that simply optimized code; they were patches that fundamentally altered the engine’s reliance on memory. For users with 8GB graphics cards, the message became clear: 8gb patch
These consoles utilize a Unified Memory Architecture (UMA). They do not have separate pools for system memory and video memory. They share a massive pool of ultra-fast GDDR6 memory—16GB of it. While the operating system reserves some of this, developers effectively have roughly 12GB to 14GB of high-speed memory to use however they please. They can allocate 3GB for game logic and 9GB for textures, or 8GB for logic and 4GB for textures. It is flexible and abundant. PC architecture is different
This has created a new tier list for PC gamers: The PCIe bus (the bridge between CPU and
