Which is more important, the type of memory or the bit width.

All important. For example, the GPU (graphics card core, more important than the video memory) needs to process 50GB of data per second, and the amount of data shipped to the GPU by 256 bits of video memory is 256 8=32B each time, so in order to meet the needs of the GPU 50GB of data per second, the number of times the video memory needs to deliver data to the GPU in 1 second 50GB 32B = 50*1024 32=1600M s, that is, the 256-bit video memory needs to deliver 1600 million data to the GPU per second to meet the GPU The demand for data, the number of times the video memory is shipped per second is actually the frequency of the video memory, and the frequency of the video memory is determined by the type of video memory GDDR5 has the highest frequency, so now high-end card video memory is equipped with GDDR5, the purpose is not to follow the trend, but to achieve a higher frequency.

It's like a person running, the width of the stride is the size of the stride, the frequency is the speed of the stride, the same is 100 meters, the small pace can be increased by increasing the frequency to beat the big stride, anyway, so both are important.

The bits of width and height of the memory are all DDR5 high video memory.

The size of the video memory can be ignored by the rookie who likes 2G video memory haha.

Bit width is the most important thing I haven't seen a graphics card with 64 bits and 256 bits per second.

The type of memory directly determines the frequency of the memory. Compare the quality of the video memory and directly compare the memory bandwidth.

Then this comparison can be compared using the memory bandwidth formula, the larger the bandwidth, the better.

Bandwidth = Memory Frequency Memory bit width 8

Bit width is the most important, video memory 1G is enough, what is being advocated now 2G, it's all.

Bit width is one of the important parameters to evaluate the quality of a graphics card, and the type of video memory is just a technical name that likes to follow the trend.

Both are important.

It mainly depends on the memory frequency and bit width, memory type and stream processing.

For example, which is more important, eating or sleeping.

Yes, the memory bit width, the larger the memory bit width, the stronger the performance.

The main reason is: video memory bandwidth (GB s) = actual frequency of video memory (MHz) x video memory data magnification * video memory equivalent bit width (bit) 8, then in the case of the same memory frequency, the memory bit width will determine the size of the video memory bandwidth.

For 128-bit and 256-bit memory with the same memory frequency of 500MHz, the memory bandwidth is: 128-bit = 500MHz*128 8 equals 8Gib s, while 256-bit = 500MHz*256 8=16Gib S, the memory bandwidth of the 256-bit graphics card is twice the memory bandwidth of the 128-bit graphics card.

In the same model, it is natural that the larger the video memory, the better. If it is a different model of graphics card, it should be considered comprehensively, and you can't just look at the aspect of video memory. It's like the GTX 1050Ti has 4G VRAM, but the performance is not as good as the GTX 1060 3G VRAM version.
