What does a non public version of PCB mean

The plate structure is exquisite, who is stronger in the public version and the non-public version?!

You may often hear the terms knife version, public version and non-public version, graphics card chip manufacturers in the factory each new graphics card chipset, will announce its public version of the graphics card samples by the way, in the future, major graphics card manufacturers in the design of their own graphics cards in the design of the board type will be the same as the chip manufacturers announced the public version of the sample, and some manufacturers will also launch some different design solutions from the sample board type, in order to control costs, reduce ** to meet the needs of the market, this is what we usually call the public version of the design, Non-public design and knife design.

The biggest advantage of using the public version design is that it can provide the most stable performance. Since chip manufacturers have undergone strict testing when leaving the factory sample graphics card, including in terms of heat dissipation performance, stability performance and power supply performance, they have adopted the most suitable model design for the work of the graphics card chipset, so the biggest advantage of the graphics card with the public version design is that it has good stability and can give full play to the strongest performance of the graphics chip.

The non-public version design is generally designed by the graphics card manufacturer according to the needs of the market. The biggest feature of this part of the graphics card is that it is cheaper than the public version of the product, especially the graphics card with knife design, because it uses the same display chipset, and the board type can be reduced to better control the cost and reduce **, but there will not be much change in performance. Such as the 6600GT Player Edition of the Shadowrun and so on.

Since most of the products with non-public design, especially the knife version, are designed to save costs, the working frequency is generally not too high, and there will be a certain gap between the performance and the public version of the product. In addition, the strength of the manufacturer is required to be very strong, otherwise there will be a series of problems, and the potential for overclocking is not great. But its biggest advantage is that it is cheaper, even so, it is best to recommend ordinary users to choose the public version of the product, and stable work is what we want.

There are four types of graphics card PCBs.

One is more shrunken than the public one, very cheap, and the performance is generally lower than the public version, and the quality is controlled.

The second is the public version, which ensures a reasonable design, and the performance is only the benchmark performance.

The third is the ordinary non-public version, which is slightly stronger than the public version, and the same is true for **, which is suitable for home use.

The fourth is the flagship level, which is much stronger than the public version, and the design in all aspects is stronger than the public one, not just PCB, which is convenient for players to achieve higher frequencies and achieve higher performance.

You should be talking about the third type, a comparison with the second type of the public version.

As long as the chip of the graphics card is the same, the only thing that affects the performance is the frequency, such as a mainstream GTX750TI, the main frequency of the public version should be 1050MHz, and the third non-public version, depending on the brand and model, generally.

At 1100MHz and 1150MHz, the performance is not much improved, the top one has a ZOTAC, the main frequency is about 1250MHz, and the top flagship of the fourth type is at most 1300MHz

Finish. So the performance gain is not significant.

The main frequency of the more advanced GTX970 is much higher, the common model of the third type can reach about 1300MHz, some high frequency can be more than 1300, and the flagship card is at most more than 1400.

Is the performance not much improved?

Yes, it's not big.

But this kind of flagship card is also meaningful, because the more advanced the performance, the greater the difficulty of its improvement, and the more ** is needed to improve a little performance, so if you don't pursue this, it is naturally meaningless, for that kind of player, for local tyrants, it still makes a lot of sense to spend a little more money to improve this.

And this improvement is not only performance, more stable, luxurious materials, excellent appearance design, workmanship, these can also be improved, not only performance.

The difference between PCB is mainly that the power supply (capacitor materials) and heat dissipation are generally selling points are chips with higher factory silent frequency, such as GTX970 public version is generally 1053MHz ASUS Gigabyte or something is 1150 or even 1250 frequency, then in addition to the good chip physique, the capacitance of the backplane should also be better Because high frequency requires a higher power supply voltage, and the overclocking performance of the non-public is also better, and the non-public with good physique can be air-cooled to 1400-1500, It's because the PCB design is better.

If it's just a general thousand-yuan graphics card, the PCB experience will not make a difference, and only high-end cards or overclocking cards played by enthusiasts will have a noticeable feeling.

Let's not talk about which match, the impression is basically changed.

In terms of demand, there is no point in changing. You don't overclock the public version of the graphics card, and the heat dissipation design is there, which is absolutely proper. As long as the full load is not higher than 80, it is considered normal. It's the same with the heat dissipation you change. If you think 78-80 is too high, it is better to change the water cooling directly

So in terms of demand, if you just want to reduce a few, it is relatively simple to open the side case cover, and there is no cost

No, it should be said that TITAN X will not be non-public in the real sense, and the real non-public here refers to the graphics card with non-public PCB + non-public heat sink.

The GeForce GTX Titan series is a very special series in the NV lineup, the earliest model is the GTX Titan, which was released in February 2013. But if you take a look at all the brands of Titan, you will find that none of the brands of Titan use non-public PCBs, at most pre-overclocking or replacing the heatsink. For example, EVGA's Titan SC is pre-overclocked on the basis of the public version, while the PCB and heatsink are still the public version design.

Another example is the EVGA Titan Hydro Copper, which is actually preset with high frequency, but the public version of the air-cooled OTES heatsink has been changed to a cold head, which is convenient for water feeding, but the PCB is still the public version of the PCB. The situation is the same for other brands, at most change the heatsink and pre-overclock, but the public version is still used on the PCB. It can be seen from here that NV has not opened the authorization of Titan's non-public PCB, so the Titan on the market, strictly speaking, has a non-public model in the true sense.

In February 2014, NV released the GTX Titan Black, and the situation is exactly the same, there is still no model that uses non-public PCB, at most it is to change the heat sink + preset high frequency. The same goes for the Titan Z, which was released later.

Seeing this, you should understand, NV does not plan to open the non-public PCB of the Titan series graphics cards, so there will be no non-public Titan graphics cards in the true sense, and the same is true for the newly released Titan X.

980Ti (Assuming a normal digital model with the GM200 core.) It should be open to non-public, because it doesn't belong to the Titan series, you can take a look at the GTX780 and GTX780TI in the same time period as Titan and Titan Black, all of which have non-public versions, and there are a lot of them. So there should be no reason why the 980ti should not be open to non-publicity.

Others don't know, X has non-public, although not as much as the X80 series, because the public version has the largest profit for NVIDIA, so the highest level TT, TTZ, TTB, TTX, TTXP has no non-public, or very few non-public.
