what I mean is to find out if my graphic card is a low, middle or high end graphic card ?What do you mean by spectrum? Are you asking about color, electromagnetic radiation that the card emits, the range of its clock frequencies, how it compares to other graphics cards?
Your question is too confusing to be able to answer properly.
Ah, now I see. The problem with answering that question is that the 'spectrum' or market class of a graphics card decreases over time. For example, an Nvidia GeForce GTX 1070 was an upper middle-end to low high-end graphics card when it first came out in 2016, but compared to the latest GPUs, it's now a low middle-end card.what I mean is to find out if my graphic card is a low, middle or high end graphic card ?
