What graphics card is recommended for the 785 and how is the 7850 graphics card?

I recommend 2 A-cards for you, one is MSI 5750

The other is Dilan Hengjin 4850 Star Diamond D5 1G. One is the 4 series and the other is the 5 series. Almost, 600 to 700. The performance is stronger than the latter, but because it is an old graphics card, the power consumption and heat generation are greater than the former.

The GTX780M is equivalent to the GTX660Ti, a desktop discrete graphics card.

The GTX860M is equivalent to the GTX750Ti, a desktop-class discrete graphics card.

The GTX870M is equivalent to the GTX660, a desktop discrete graphics card.

The GTX880M is equivalent to the GTX960, a desktop-class discrete graphics card.

。。The desktop version of the GTX780 graphics card is at the same performance level as the A-card RX470. Its performance is equivalent to the high point of the GTX970M for mobile graphics, or the low point of the GTX1060 3G version.

The GTX780 is slightly stronger than the GTX980M and weaker than the GTX780M SLI. (All of the above are silent frequencies).

The GTX980M is slightly worse, and the GTXM980 is a bit stronger.

At the moment, there is no graphics card on a laptop that can be compared.

The single card is over 1179, GTX1060 level, and the dual-channel small super is 1070 level, in general, the power consumption and video memory are outdated, but the performance is still high.

The performance of the graphics card is a part of the performance of the system, and its performance is determined by the above four steps, which is not the same as the performance of the graphics card.

The first step is for the CPU (the core of the computer composed of the combinator and the controller, called the microprocessor or ** processor) into the graphics card, and the last step is for the graphics card to send data directly to the display.

At present7850 a lot,There are a line of ASUS、MSI、Sapphire also has a second line of radium、Mingxuan、Weconex,So many brands are really difficult to choose, but I really know how effective it is when I actually use it,I received a quick ASUS dragon7850 2G version in the previous paragraph,It's a new version of the 1GHz graphics card,Go home and run the island、Metro2033、GTAThe fee card games,Efficient picture settings are basically stress-free,The temperature and noise are better than expected,Recently, the price seems to have been reduced to 1699, You can find out about it. Or go to JD.com or something.

The GT740 is much better. Here's why:

1. Although both are low-end cards, the performance gap is still large. GT is the identification letter of the low-end card of the N card, and GTX is the identification of the mid-to-high-end card;

2. GT820, GF117 architecture, 28nm process, 96 stream processors, core frequency 775 938MHz, ROPS TMUS 8 16;Memory DDR3, bit width 64bit, memory frequency 900MHz;

3. GT740, GF117 architecture, 40nm process, 384 stream processors, ROPS TMUS 16 32;Core frequency 993MHz, video memory GDDR5, bit width 128bit, frequency 5000MHz;

4. GT820 is a vest product of GT720. From the comparison of the above parameters, it can be seen that the performance difference between the two is still very large.

If Nvidia's graphics card models are all in the same ranking, it should be GT740! Because I don't know much about the configuration of the notebook, I can't guarantee it! At least, the graphics card of the desktop is ten digits, the higher the memory bit width, and the higher the grid!

+1 on the hundredth digit is an upgraded version of the original! 40 is several notches higher than 20!

The 7850 is still very expensive, which is the biggest problem, otherwise it is definitely 7850, the Hawk is even more expensive.

400w is a bit reluctant.

In fact, the performance difference between the 6850 and 7850 is only about ten to twenty percent under your CPU. An extra 500 dollars doesn't make much sense.

The i3 2120 plays games at best and AMD X4 955 a level. Actually, the card you typed wrong is just right. However, if you have a larger budget, the R 7850 Hawk will definitely improve the performance of the game, but it will not be a leap forward.

It's not that Hawk is more expensive In fact, now Hawk's MSI 78502G is more than 1300 points and I bought it. Anyway, don't buy ASUS ASUS is more expensive than other brands.

Sapphire is also very good A card boss Don't explain I don't recommend Dilan The workmanship and heat dissipation are not as good as the military materials of Sapphire and MSI.

7850 ... The power supply can be brought up... 6850400w will be no problem. The new 7850 architecture consumes less power and is no longer a problem.

CPU recommends using i3-3220 graphics card recommended sapphire hd775 platinum version, as long as more than 600, 28nm process, full load power consumption of more than 70W, now the computer hardware performance is excessive, most games can be played smoothly.

GT820M and GT730M Compared with GT730M, GT730M is better, GT820M is a low-end graphics card, it is an entry-level discrete graphics card in a notebook, and the following is a comparison of the parameters of the two graphics cards:

Video memory capacity: 2048MB for GT730M and 2048MB for GT820M.

Memory bit width: 64 bits for GT730M and 64 bits for GT820M.

Stream capacity: 384 for GT730M and 96 for GT820M.

Core frequency: 725MHz for GT730M and 625MHz for GT820M.

Both of these are garbage, and the graphics cards with the second number below 5 are all ultra-low-end products, 5 is entry-level, and 6 is mid-range.

It's all low-end graphics cards.,The gap is very small.,It's nothing for daily use.,If you're playing or drawing.,Change to a better configuration.。

820 and 730, the performance is half a catty, but 820 is more power-efficient, so it should be said that 820 is better.

However, both of them are low-end entry gadgets, that is, the performance is slightly better than the integrated graphics card, but the gap with the mainstream game graphics card is still obvious.

Most gamers think that x50 or above is a decent graphics card. Requirement to play big games is x60 or above.
