Why it's important to know the functionality of VRAM? First of all, efficiency allows us to ensure data exchange between the RAM and VRAM GPU's endless and waterproof GPU, which is important for gaming, since most current games use highly developed systems for RAMDisc.
In addition, we can be sure that we do not have the capacity or frequency, something important in which the frozen models are worse.
VRAM functionality is flexible and very difficult to display
Although the opinion says: "VRAM bandwidth is obtained by doubling the VRAM speed by the bus and that this in-state data is accurate, the reality shows otherwise.
In our case and as a practical example, the GTX 1080 Ti has to offer in all its versions about 484 GB / s thanks to its 1375 MHz and its 352 rounds. How effective is your VRAM? To see it we will use the system vRAMbandwithtest, which you can download here.
The program is very simple and will only require us to provide a working version, where the MSDOS screen is opened and then the test starts, which will be divided into two different parts.
As we can see, in the first wave it will test VRAM based on different block allocations, where as we see in each assignment we will provide bandwidth resulting in GB / s. Recalls that we start from theoretical 484 GB / s, the 350 GB / s on average
The second part of the test is limited to the cache memory bandwidth tests, which, as expected, are much higher than that of VRAM.
As we can see, the performance of the cache is affected, because the GB / s it provides is directly determined by the VRAM bandwidth when running the test.
Therefore, as long as we have a decrease in performance when measured with vRAMBandwithtest Above 25-30%, it will show that everything is working fine, because measuring the actual VRAM performance is not possible without an official product benchmark.
When a system tries to copy files to provide the same bandwidth as a result, it must start working with the chip, which, though very fast, does not return that result to the system, but compares the read and write gains with subsequent loss of performance.
The result is the sum between both, so we have to keep this in mind so as not to be shocked.
