Computing power of OC graphics card
genuine, rtx2070s is the most cost-effective, money is better, and you don't need to pay attention to parameters
in terms of brands, the public version graphics card is preferred, which has stable performance and is suitable for rendering, while other brands need time to adapt after the public version driver is updated, which is prone to small problems
moreover, the gap between the 20 series and the 10 series is not very big, and even 1080ti games are not as good as rtx2080s
if you are not sure about the old card, you can choose the shop with warranty, and Taobao Jingdong can guarantee it
currently recommended combination: 2600 + 10703600 + 1070ti, 3700x + 1080ti
why not recommend 1080? Because 1070ti is more powerful than 1080, please refer to cgdirector professional evaluation.
The differences between the graphics card with OC and ordinary graphics card are: different overclocking, different service life, different heat dissipation performance
1. Graphics card with OC: the graphics memory of graphics card with OC can automatically overclock2. Ordinary graphics card: ordinary graphics card can't automatically overclock, but can manually overclock
Second, the service life is different1. For the graphics card with OC, the service life of the graphics memory particles of the graphics card with OC is longer than that of the ordinary graphics card
2. Ordinary graphics card: the service life of ordinary graphics card is shorter than that of graphics card with OC
3. Different heat dissipation performance1. Graphics card with OC: the heat dissipation performance of graphics card with OC is better than that of ordinary graphics card
Ordinary graphics card: the heat dissipation performance of ordinary graphics card is weaker than that of graphics card with OCOC is the abbreviation of English overclock, which means overclock
before leaving the factory, this kind of graphics card has been properly overclocking the display chip. Therefore, in the graphics card with the same level chip, the speed of running the game is faster, but the problem is that the heat is large, the price is expensive, and the service life is short
in the case that the original manufacturers do not support overclocking, players often force overclocking through both hardware and software channels, such as enhancing the external frequency of the system, adding voltage and other brutal ways. Previously, it was popular to modify the registry, call out hidden properties or install overclocking software, and start with improving the utilization of chips
although these methods are effective, they are accompanied by high risks. If the heat is not cooled in time, the service life of components will be greatly damaged
overfrequency mode:
one is the video card driver with FM
the second is to develop special software, such as the shadow gtx1070ti Hall of fame, which has a special software called "shadow magic disk" to provide overclocking services and customize parameters
the third is physical unlocking. Some of them have a button on the graphics card, which is specially used for overclocking. Players only need to press it. When the GPU is running, they can overclock themselves to solve the problem
1. Different overclocking capabilities:
the OC version of the graphics card supports automatic overclocking (the default frequency is higher), and the ordinary version requires the user to manually turn on the overclocking
2. Different heat dissipation performance:
in order to meet the needs of overclocking players, the OC version has made more optimization and improvement in heat dissipation than the ordinary version, so as to rece the greater heat brought by overclocking
3, different service life:
OC version graphics card uses a longer service life than ordinary version, so as to ensure that it can maintain high-frequency operation for a longer time
extended data
the graphics card is mainly responsible for converting the display signal sent by the host computer to the general electrical signal, so that the display can understand what the personal computer asks it to do. Graphics card is mainly composed of graphics card motherboard, display chip, display memory, radiator (radiator, fan) and other parts
the main chip of the graphics card is called "video chipset" (also called GPU or Vpu, graphics processor or visual processor), which is the main processing unit of the graphics card. There is also a memory similar to computer memory on the graphics card, which is called "display memory" for short
in the early stage, the graphics card was only a simple one, which only played the role of signal conversion; We generally use graphics card with 3D picture operation and graphics acceleration function, so it is also called "graphics acceleration card" or "3D acceleration card". The earliest graphics card on PC is MDA and CGA two-dimensional acceleration card on 5150 personal computer launched by IBM in 1981
the graphics card usually consists of bus interface, PCB board, display chip, video memory, RAMDAC, VGA BIOS, VGA function pin, D-sub socket and other peripheral components. Most of the graphics cards also have VGA, DVI display interface or HDMI interface, S-Video terminal and display port interface
Renderers are divided into CPU and GPU renderers,
because the floating-point computing power of GPU is much higher than that of CPU,
simply speaking, GPU renderers are faster than CPU renderers
the old GPU render is octane
therefore, C4d CPU standard render is not as fast as octane render.
since R19, C4d has added GPU render prorender,
prorender is still in its infancy in R19,
there is no way to compare with other GPU render,
whether prorender can surpass octane render,
at least depends on the update of C4d R20
the advantage of prorender is that it supports a card and N card.
however, most GPU renderers such as octane and redshift only support N card
Demo04: OC renderers are suitable for those who don't like the late AE, because the effects rendered by OC are very late. Of course, if you watch too much, you will get tired of it. For example, many domestic people who do digital advertising such as mobile phones like to finish a lot of work in C4d and use a little AE, while those who do column package financial news titles will use a lot of 3D and late AE Contrary to the nature, 3D is softer than space machine in the later stage.
Demo04: OC has made improvements in the render program, which means that the program automatically processes the color in the later stage. Designers without the help of the post-processing teacher have to make a one-step effect and learn from octane directly. At least the things they make are bigger. Sometimes, they still want to default the render. Many ordinary people are not happy with it Those who like things with exaggerated colors are more flexible with the help of the late stage teacher. After all, what OC renders is that kind of taste
1、 The overclocking capability is different:
1. "OC" is "over clock" in the graphics card model, which means that the graphics card has overclocking before leaving the factory. To be exact, it is a graphics card whose frequency performance is higher than that of the official public design. OC version graphics card supports automatic overclocking (the default frequency is higher)
the manufacturer passed the stability test in the process of overclocking, and the stability was consistent with that of the ordinary version. But the performance is slightly higher than the ordinary version. OC version of the graphics card in order to work stably, the workmanship is better than the ordinary version, the material and power supply is more solid, so the cost is relatively high
2. The normal version needs users to manually turn on the overclocking. Materials and power supply are not as good as OC version< 2. Different heat dissipation performance:
1. In order to meet the needs of overclocking players, the OC version has made more optimization and improvement in heat dissipation than the ordinary version in order to rece the greater heat brought by overclocking. OC version of the graphics card in addition to the official provisions of the frequency, in the cooling conditions allow still can increase the frequency
2. The heat dissipation of ordinary graphics card is worse than that of OC version, and the temperature may be maintained at a higher level when it is used in overclocking
Third, the service life is different: 1. The OC version of the graphics card uses a longer life than the ordinary version to ensure that it can maintain high-frequency operation for a longer time
2. The grain constitution of the ordinary graphics card is not as good as that of the OC version. If it is used for a long time, the service life may be affected
the Ti of the graphics card is mainly a proct of NVIDIA. According to the habit of N card, if the graphics card sells well and the value is high in the long-term plan, ti will be added after a certain type of graphics card, such as the gtx550ti of that year and the gtx980ti of now. The main reason is that 550ti sells well at that time, the price and performance are reasonable, and the user is willing to pay the bill, But the high-performance version is too expensive, so there is a Ti version. The price and performance are between GTX 980 and Titan, that is, the enhanced version of gtx980, 660 or 550
Hawk is almost the "emperor version" in MSI, which is the final user's favorite and enhanced version in a certain model< br />
OC is the acronym for "over clock", which means "overclocking"
in the instry, the model of graphics card with OC usually means that the model of graphics card is pre overclocking by the manufacturer. That is to say, the frequency of this model of graphics card is higher than that of the public version card issued by the chip manufacturer (NVIDIA or AMD), and the performance is stronger
for example, the frequency of NVIDIA public 980ti GPU is 1000 (base) - 1076 (boost) MHz, while the GPU of 980ti supreme OC of a certain brand is 1253 (base) - 1355 (boost) MHz. Compared with the public card, the frequency is increased by 20-30%

video card overclocking precautions
1. When we adjust the video memory frequency and kernel frequency of the video card, we should not increase too much at one time, and it is better to make multiple adjustments at an interval of about 5MHz. If in the process of overclocking pixel errors or splash screen and other phenomena, we need to immediately adjust to the normal frequency, in order to prevent damage to the graphics card
2. Pay close attention to the temperature of the graphics card when overclocking, because when overclocking, the power consumption of the graphics chip will be large, resulting in a lot of heat. If the heat dissipation is not timely when overclocking, it will often lead to the damage of the graphics card
3. It's better to use the public version of the overclocking driver for your graphics card instead of using the public version of the overclocking driver. There may be some problems in the cooperation between the graphics card and the overclocking software, because the drivers that are not public versions are often modified on the public version of the driver
4. Understand the overclocking information of your own graphics card, and pay attention to the degree of overclocking of your own graphics card. Avoid overclocking amplitude is too large, too much overclocking will lead to the decline of the service life of the graphics card is too fast. Moreover, it will affect the efficiency of the graphics card
5. Many graphics cards can improve the performance by about 20% after overclocking. However, the software test results after overclocking often do not improve much. Why? Because the performance of the graphics card not only depends on itself, but also depends on the CPU. We can solve this problem by replacing a CPU with a higher dominant frequency< br />
