When it comes to graphics cards, there are always a few models that some gamers call "IQ detection cards". Maybe many people don't know about this IQ check card, the so-called IQ test card here, in fact, refers to using an irrational state to choose a graphics card with very low performance, and then I think he is a good graphics card, the following models are often called IQ cards, such as GTX1030 GTX1050TI RTX2060 GTX1060 3G version, RTX3050, etc...... In fact, these graphics cards are not IQ cards in the real sense, and I will tell you about a real IQ card, which is still in use.
Today I will introduce you to a real IQ card, his existence is the ceiling of the IQ card, this graphics card is the GT610 4G version released in 2012. This card uses 64bit width, 40nm process, core frequency 810mhz, video memory type DDR3, video memory frequency 1800GHZ, 48 stream processors, video memory capacity of 1G 2G 4G and even some merchants brushed the video memory capacity of this graphics card to 1TB, which was also called the "mad cow version" by players back then. To be honest, 1TB of video memory capacity is indeed a bit crazy. A little bit of graphics card common sense will not choose him, but on the contrary, due to everyone's low awareness of hardware at that time, under the encouragement of merchants, many friends bought the GT610 4G version, which was known as the "king of cost performance".
To be honest, judging from this model alone, it is estimated that many friends can't see where his IQ is, and the apparent existence of 4G seems to be no problem in this era of 8G and 12G at every turn. But here I want to tell you that the 6 series high-end graphics card 690 is only 4G, as the 6 series of the bottom 610 graphics card, the processor stream is only 48, do you say he is on the 4G video memory is appropriate? You must know that according to the graphics card parameters of 610, it is not necessarily used up with 1G video memory, you say the last 4G and then raise the price, you tell me that he is not an IQ card, what is it?
Everyone must understand that the 610 is only an entry-level low-end card, and its performance is not as good as the performance of the core display. Some friends even joked that "please unplug the independent display to improve the performance of the core display". It means that it is more reliable to use this graphics card than to use the core display directly. But in that year, this graphics card was broken by merchants, and some manufacturers also launched a 4G version in order to cater to the market, and it was also known as the most cost-effective graphics card ever. However, paper can't contain the fire, and when the player gradually rationalizes from the joy of this big video memory, he finds that the big video memory is just a selling point, and the actual experience is really poor. But there is no way, I can only admit it by myself if I buy it.
It's funny to think about it now, because I almost bought it at the time. Mainly at that time, both graphics card manufacturers and sales stores were mainly promoting this so-called "super large video memory graphics card". And they also secretly changed the concept of the graphics card, saying that the game flow is not smooth, mainly depends on the video memory, and the larger the video memory, the better the performance. As for the key parameters of the graphics card, I don't talk about it. In addition, the price was indeed cheap, so many people were recruited back then. In fact, for the graphics card itself, the video memory does not represent its performance, it is only a core parameter of the graphics card, and the most important thing is to look at the architecture and core codename. These are the keys that really determine the smoothness of the graphics card.
Here is a way to identify Nvidia's low-end cards, we don't have to remember too many parameters, just look at the numbers. Generally speaking, Nvidia's three-digit graphics card, we only need to look at the second digit, as long as the second digit is below 4, it is a low-end graphics card, such as GT210 GT610 GT630 GT640 GT710 GT730 GT740, etc. For four-digit graphics cards after the 10 series, we can look at the third digit, as long as the third digit is below 4, it belongs to low-end graphics cards, such as GT1010 GT1030, etc...... The smaller the number, the lower the performance, which is like the 610 graphics card, which is the bottom of the low-end graphics card. With such a graphics card, no matter how much video memory you put on it, it is equal to zero. I don't know what other friends think about this, do you think those graphics cards should be called "IQ test" cards?
