Comparing 8GB versus 16GB of graphics RAM.
Comparing 8GB versus 16GB of graphics RAM.
It’s simply how the system distributes resources. For instance, a game running on 32GB of DRAM can increase usage to 16-18GB. When it runs with 16GB, consumption drops to around 12. Programs often request more than necessary, and the PC will allocate the resource if it isn’t needed elsewhere.
8gb vram has been around for some time and seems to function adequately, but if you have the chance to upgrade to 12gb or 16gb vram without a significant price increase, I’d recommend doing so. Keeping your components longer might mean the cards with higher vram will last longer.
1080p with 8gb ram supports good textures. A 128 bit bus is sufficient, paired with 16 lanes.
1440p requires 10gb to 16gb for advanced settings. A 192 bit or 256 bit bus with 16 lanes is recommended, as fewer lanes may hurt performance on older hardware.
4k needs 16gb to 24gb and a 384 bit bus.
You won't probably notice the changes. VRAM is located in the graphics card and has become a marketing concern. It seems more about performance than functionality. A game should have most of its data in VRAM when it's used most often, which is somewhat similar to regular RAM. If a game needs something not in VRAM, it must transfer it across the PCIe boundary, hopefully from actual RAM and not from a hard drive. It doesn't add value to know how much of the available VRAM is filled. It's possible that much of what's there isn't necessary. What remains unclear is how quickly VRAM is exchanged. VRAM is controlled by the graphics card driver and the game itself, and effectiveness can vary between AMD and NVIDIA cards, as well as between different games.
There was an older performance test comparing 2GB with 4GB VRAM, which showed no significant difference. More recent tests also confirm this:

Moreover, no game developers aim to restrict their audience by demanding excessive VRAM. The VRAM available will match the card's specifications.
This typically happens when users adjust settings excessively in games that are already poorly optimized. Recently, much of the criticism has shifted toward developers for failing to optimize properly and for establishing overly ambitious graphics targets. 8GB is generally sufficient for most PC gamers.
But your approach relies on comparing system RAM instead of VRAM, and even if the principle remains consistent, proving it would require further clarification.
