Graphics card comparison problem, what does the difference in graphics card affect

Of course, 9550, you can find out which factory's 6200a is double 128.

If double 128 is not AGP's.

MSI's little strong.

AGP's 9550 is the price you say.

Nothing compares to the good of using DDRII video memory.

Recommended: Xunjing 6200A DDRiii, 499 yuan.

MSI's little strong.

AGP's 9550 is now 299.

It depends on whether you are mainly playing games or other software applications, if you play more games, I recommend using 9550, the effect is better than 6220. Otherwise, use 6220

1 All of all, first of all, you need to see what kind of speed your motherboard graphics card is: x4 x8 e-x16

Nowadays, the average hardware enthusiast doesn't care about its capacity, and some have a video memory of 512MB or even less than 128MB. Obviously there is not everything, its frequency and transmission speed are the fundamentals of performance.

The main thing to pay attention to should be the bit width, for example: 128MB graphics card, the bit width is 128D compared with 512MB 64B, the performance is still 128B advantage! Because of the wide bits, the bandwidth can be calculated!

Large bandwidth is the foundation of performance, which can give full play to the video memory, otherwise no matter how large the capacity of the video memory is, it can only be stuck like pouring water in a bottle (video memory capacity)!

Therefore, it is recommended to buy a bottle with a large mouth (bit width) and use 128 bit width, which can meet the performance of current business, games and so on.

Then there is DDR1, DDR2, DDR3, which is also the speed at which the table is obviously stored! This means that speed can be exerted in a wide channel!

Then there's the speed of the graphics card interface on the motherboard, agp:

1x 266mb/s

2x 532mb/s

4x 1g/s

8x, commonly referred to as x4, can be used exactly for 3D. For gaming performance, it's okay! Its data transfer rate can reach 1G!

It is recommended that you need to look for a performance ratio, preferably with PCI-E 16X can reach 8G!

Depending on what game you play, all games have a bottom line on the requirements for the graphics card, such as at least what level of API must be supported, and so on. As long as your graphics card can support the API (DX), you can play the game, and on this basis, the strength of its performance will determine how many effects to turn on, and how much resolution to use.

Can't get into the game! The game can't load After the game will Tommy is card

In general, the 40 series graphics cards have a great performance improvement compared to the 30 series graphics cards, taking the NVIDIA RTX 4080 and NVIDIA RTX 3080 as examples, which are mainly manifested in the following aspects: core architecture, process technology, frequency, sensitive TDP, and stream processor.

1. Core architecture: The NVIDIA RTX 4080 graphics card adopts the new Lovelace architecture, compared with the Ampere architecture of the NVIDIA RTX 3080 graphics card, the Lovelace architecture has been optimized in many aspects, such as higher CUDA cores, higher frequency, more RT cores and Tensor cores, etc.

2. Process technology: The NVIDIA RTX 4080 graphics card uses a more advanced 5nm process, while the NVIDIA RTX 3080 graphics card uses an 8nm process. More advanced processes can be incorporated to provide higher integration and lower energy consumption, thereby improving the performance of the graphics card.

3. Frequency: The base frequency of the NVIDIA RTX 4080 graphics card is 1925 MHz, which is also higher than the NVIDIA RTX 3080 graphics card of 1440 MHz, and it also supports GPU Boost technology, which can automatically increase the frequency according to the load.

4. TDP: The Thermal Design Power (TDP) of the NVIDIA RTX 4080 graphics card has also been improved compared to the NVIDIA RTX 3080 graphics card, which means that the NVIDIA RTX 4080 graphics card requires more sensitive power to run, but at the same time it can also provide higher performance.

5. Stream processors: The stream processors of the NVIDIA RTX 4080 graphics card have also come to 9728, which is more than 10% higher than the 8704 of the NVIDIA RTX 3080.
