The top graphics card at present.

NVIDIA RTX3090 is the highest performance graphics card on the market.

As far as the core performance of graphics chips is concerned, the best graphics cards at present are high-end graphics cards produced by NVIDIA and AMD. NvidiaGeForceRTX3090 is one of the most powerful graphics cards owned by Nvidia, with 10496 CUDA cores and 24GBGDDR6X memory, which can provide excellent game and computing performance. But it is very expensive and suitable for professional users who need high-end games and computing tasks.

The size of the video memory also has a certain impact on the performance of the graphics card. Generally speaking, the larger the memory, the more graphics data the graphics card processes and the faster the image processing speed. At present, the memory size of high-end graphics cards is generally above 16GB. In addition, the bandwidth of video memory is also one of the important indicators of graphics card performance. The higher the video memory bandwidth, the faster the graphics card can read and write data, and improve the graphics processing speed. At present, the memory bandwidth of high-end graphics cards is generally above 400 GB/s.

How to reasonably match graphics card and CPU

When matching CPU and graphics card, theoretically, we should consider the performance positioning matching of both parties, and don't hold each other back. However, considering that most games require more graphics cards than CPU at present, it is generally suggested that friends who play games can control the graphics card budget to about 0.5-3 times that of 65438+CPU. Of course, budget and demand are the primary considerations, but the general installed capacity pays attention to cost performance. Under sufficient conditions, minimizing the installed budget is the pursuit of mass users.

In addition, if it is not the main game, such as the main design and video rendering, the game is mainly to play ordinary 3D games. In this case, the CPU is more important than the graphics card. In the case of limited budget, the budget is mainly allocated to the processor. For example, the CPU chooses i58500 1800 yuan, and the graphics card chooses GTX 1050Ti.
