Many people hope that the memory of their graphics cards can be as large as possible. Many hardware players have done this so far, such as using RTX 3070 8GB upgraded to 16GB, but this is the first time I have seen the addition of a memory switch. Recently, a YouTube channel has given this to the RTX 3070. It can switch between 8GB or 16GB memory at any time. Although it feels useless, it still feels fresh.

Someone abroad has magically modified the RTX 3070 to have a physical switch of 8GB and 16GB memory, allowing you to change the desired capacity at any time.
Recently, the foreign YouTube channel Casual Gamers and Paulo Gomes teamed up to add an MSI Ventus 2X model RTX 3070 graphics card to the memory switch. They can choose whether the RTX 3070’s memory should be 8GB or 16GB according to their needs at any time. It looks like this. It’s a pity that they didn’t share too many details about how to modify it, nor did they show what the PCB looks like under the cooling fan:

For most players and users, the multi-memory switch of the graphics card looks cool, but in fact it is not helpful, because no matter what the purpose is, the maximum 16GB VRAM memory must be directly used to obtain the best performance.
It seems that the only purpose is that it is more convenient for hardware test channels like us and Casual Gamers. There is no need to prepare two graphics cards or spend effort to unplug and plug them in. You can easily get the performance of 8GB and 16GB with one RTX 3070. In this video, Casual Gamers does this to compare the performance gap of RTX 3070 8GB vs 16GB.
Casual Gamers tests many games, and the picture below is one of them, “Castle 4: Remastered.” In the highest quality setting of 1440p, the difference between 1% and 0.1% Low FPS is the most obvious, especially the 0.1%. Of course, the average FPS has also improved. The RTX 3070 8GB originally could not run 60FPS, but after changing to 16GB, it can reach 66.4 FPS:

The same is true for “The Last of Us”. The difference between 1% and 0.1% Low FPS is the largest, and the average FPS is smaller:

However, not every game has improved. For example, in “Forza Horizon 5”, even at the highest image quality setting of 1440p, the game performance of RTX 3070 8GB and 16GB is almost the same, without any improvement:

So in summary, it still depends on the games you play. For some, 8GB is really enough, and there is no need to use 16GB. Casual Gamers believes that for today’s games, it is best to have at least 12GB of video card memory, and 8GB is really not feasible.
I think if you don’t play AAA game titles and your budget is entry-level, then 8GB is still fine. You don’t have to go for 12GB or 16GB and spend more money.
