The core frequency of the graphics card, the memory bit width, the memory frequency, and the role of

In fact, the parameters of the current graphics card are not as much as the previous graphics card, and there are very few shrinking graphics cards, and the indicators are already relatively balanced.

The core frequency is the processing speed of the display core. Of course, bigger is better, but it's also related to the core architecture. High frequencies inevitably lead to high power consumption.

The architecture of the graphics card is very different from the CPU, and the number of stream processors can be regarded as the number of cores, which I personally think is more important than the frequency).

Video memory is the temporary storage of important data for the core so that it can be accessed immediately. Video memory is important during a large number of renderings. If it is a reservoir, the size of the memory is the volume of the reservoir.

Then the bit width can be regarded as the diameter of a water pipe that is stored to the core, and of course, the larger the better. He decides the amount of data that can be transferred in one clock cycle.

Memory frequency is the number of clock cycles in one second of video memory. He can be seen as the flow rate of the water in this pipe. Therefore, the high memory frequency can compensate for the lack of bit width.

GDDR5 has an extremely high memory frequency, so in order to balance the cost, the memory bit width has been reduced, but it does not affect performance in any way.

In simple terms, memory speed = memory bit width x memory frequency.

Your set of configurations is very strong, 5770 is a fast card, it depends on how you use it.

It's really tiring to type Just 4890 More than 100 watts of power consumption, I won't choose him if I die, buy it to make a barbecue. The power consumption of the HD5000 series card is very reasonable, I don't think D11 is a selling point, I just like the low power consumption and heat dissipation convenience brought by the 40nm process, which is also the guarantee of the life of the graphics card.

Mid-range gaming graphics card 5770 5750 is the absolute first choice. 5830 is not much, the cost performance is poor, and it is directly ignored.

If you just look at the high please, a piece of HD5570 is enough, and it is of course best to play games with HD5700 series and above.

At present, the most important indicator to measure the quality of the graphics card is the number of stream processing units, why HD5770 is so much worse than HD5870, because the stream processor has been cut in half, why HD5870 is so much stronger than HD4870, because RV870 is actually RV770*2, just a process improvement.

Memory frequency, bit width, and capacity are put together, the memory frequency is the size of the memory access speed of a clock cycle, the bit width is the size of the data that can be passed at one time, and the GDDR5 is four times the transmission rate, and the high memory frequency makes up for the lack of bit width, so to speak, 128bit GDDR5 = 256bit GDDR3 (different frequencies). In general, when comparing bandwidth, bandwidth is the most important. However, in some special tests, 128-bit GDDR5 is weaker than 256-bit GDDR3, and bit width is sometimes irreplaceable.

Needless to say, the memory capacity is very important, and it is less than 512M direct pass

Trade-off order: number of stream processors (n cards multiplied by 5), memory capacity, memory bandwidth, and core frequency.

Your configuration is OK, HD5750 performance is acceptable, hard disk is recommended to choose 320G or 500G

In fact, HD5750 is not as cost-effective as HD4860.

PS: DX11 games are basically missing for HD5750, and the performance is too weak. If you really want to play DX11 games, it is recommended to wait for the GTS400 series, and replace it with an integrated display for the time being.

At present, it seems that the performance of the N card DX11 is far better than that of the A card HD5000 series, the main FERMI is redesigned for the DX11, while the HD5000 series is copied from the original design, the more special effects there are in DX11, the lower the processing efficiency. In this prediction, the A card HD6000 series will definitely lose to Fermi, because HD6000 is still copied, and Fermi will really be powerful when the process matures, wait and see.

Memory bit width x frequency = memory bandwidth, which affects the performance of the graphics card together with the core frequency and memory capacity. Compared to those, the number of stream processors of the graphics chip, ROP and light and shadow units, and DX versions are also critical.

Is the AMD frequency X4 945 or X2 545? Neither is recommended to buy. X6 six-core AMD is about to go on the market, the lowest price is said to be about 1000, and then the 945 will either drop sharply or be delisted.

The X2 545 is not cost-effective, unless it is a guaranteed core version. The processor recommends around 500 Athlons X3 435 and 700 X4 630

In addition, the graphics card has changed recently, HD5770 already has 799 second-line brands (Shuangmin, etc.), you can also consider it if the workmanship is not bad.

1. Take the N card as an example, introduce the specific steps to reduce the frequency of the graphics card, that is, the opposite step to overclocking, which can be completed with the help of the N card overclocking software NVIDIA Inspector

3. Run the installed software, click the display overclocking at the bottom of the main interface to see the overclocking interface, which is basically a Chinese display, and most people who have some knowledge of hardware can understand it.

The first is the frequency of video memory,Generally, you have to go online to check how much value is appropriate,You can reduce it little by little,If there is a problem, there will be a blurred screen,Crash。 The second is the core frequency, the same reason, but the reduction will be smaller, not much each time, and the other same video memory frequency. The last one is voltage regulation, which the software detects from the bottom of the boot program to the highest and lowest levels, these two values are the voltage range in which the GPU chip operates, if it is below this voltage may cause unstable operation, if it is too high, it may burn the chip.

Since the normal amplitude of overclocking almost does not require the help of voltage control, and the large adjustment of the voltage increases the probability of the display chip burning, it is not recommended for ordinary users to adjust this voltage significantly.

The leftmost one is the fan speed, if you want to overclock, you must turn on the fixed fan speed, which is generally determined according to the overclocking amplitude (the minimum is more than 70% and the highest can be 100%).

It is recommended that you can turn off the overclocking software or use the downclocking when dealing with general daily applications, which is good for the life and power consumption of the graphics card.

After the adjustment, you can directly click on the frequency and voltage, and it can take effect.

Xiaobai don't overshoot, there are a lot of overclocking software on the Internet, small ones will be used, but it is not recommended for Xiaobai to use, I won't say what software, overclocking should be careful.
