How to identify the graphics card model

The naming rules for the ATI Radeon HD series are: 1, the first number, such as 4850 and 5850, 4 and 5, which represent their generation. 2, the second number: 8 and 9 are positioned as high-end, 6 and 7 are mid-end, 4 and 5 are low-end products. For example, 4890,5890,5870 are the fourth and fifth generation of high-end products (dream luxury), while 4650,4670,5750,5770 are the middle end of the fourth and fifth generation of products (ideal high configuration), and then 4450,4350,5470 are low-end products (ordinary real goods). 3, the third digit: such as 5850,5870,5890, the first two indicate that it is the fifth generation of high-end products, the following 50,70,90 is in the high-end inside the low, medium and high-end. 5850 is the low end of the 58 series, 5870 is the middle end of the 58 series, 5890 is the high end of the 58 series.

NVIDIA graphics card Geforce 10th generation product "GeForce+ positioning + model +M" series naming rules: 1, positioning letter explanation (from high to low) : Ultra: Nvidia flagship product, the strongest in this series. (Almost never seen on the market) GTX: Its performance is between GTS and Ultra. Generally Nvidia's first high-end products. GTS: Always Nvidia's third strongest product (GeForce 2 GTS and GeForce 8800GTS can be shown), performance is below the GTX, and a little fuzzy compared to the GT. GT: Short for "GeForce Technoloty", the frequency and line are significantly improved over the LE GS SE XT. GS: Compared to GT, the reduction of the rendering line or video memory width, the frequency is generally below GT, and the performance is below GT due to specification limitations. LE: Short for "Limit Edition", representing a limited version, representing an entry-level product in a production series, mainly because the frequency and specifications are reduced compared to the standard version. 2, model number explanation: (similar to A card) such as Geforce GT 555 (a good graphics card), the first 5 represents the fifth generation, the second 5 represents the middle end, the third 5 represents the level in the 55 series. If it is 485, 470, 460 these four generations of high-end series with GTX to prefix, such as: GTX 485, GTX 470 and GTX 460, these are the real sense of high-end graphics cards, is the favorite of game enthusiasts. The general 55 series belongs to the top configuration of the general public, such as GT 555, GT 550,GT 540,GT 445, these are also quite good, and GT 525,GT 520,GT 420,GT 415 these performance will be worse, but the GT series is already a good graphics card. There are some such as: Geforce 410, Geforce 315, Geforce 310, etc., the middle of the omitted positioning letters are completely entry-level graphics cards, to play the game colleagues please choose carefully. 3, the letter M explains: Mobile, means mobile platform. The one without M is generally desktop, and the performance is stronger than that with M
