ATI Mobility Radeon HD 4200 isAMD M785G chipset based solution (integrated). The characteristics of this integrated graphics almost completely coincide with the parameters of the older solution - HD 3200. This is the previous integrated map in the series. Consider the main characteristics of this integrated solution, as well as the results of testing in games and the most successful laptop models based on this card.
Options
It should be borne in mind that today is not releasedlaptops based on this chip. The video card was released a long time ago, and even at the time of release it could not boast of high performance. Yes, and at the time of release it could be called new with a very big stretch, because ATI Mobility Radeon HD 4200 specifications are almost completely consistent with the parameters of ATI's HD3200 card. Partly because of this, the decision of the buyers was not met very well.
The core of the card is made according to the 55-nm process technology, and itsfrequency is 500 MHz. It uses a total of 4 texture units, as well as 40 stream processors. The bus width is 64-bit, the frequency is 400 MHz (the effective one is 800 MHz).
New and unique technology thatused in the new ATI Mobility Radeon HD 4200 card, was the ATI Stream. This is an analogue of Nvidia's CUDA technology, which allowed the use of a video card resource for non-graphical calculations. At that time there were very few applications that would support this technology, but over time they became more. There is also support for HDMI interface version 1.3 (instead of the outdated version v1.2), so you can output 8-channel quality sound directly to the TV.
Also in the ATI Mobility Radeon HD 4200 video cardAn updated version of the UVD 2 decoder was used, which uses more resources of the graphics core when playing HD content. This removes some of the load from the processor. Interesting is the technology ATI PowerPlay, which can change the frequency of the graphics core in a dynamic mode, depending on the load. This results in energy savings in idle mode. The technology saves battery power, which is extremely important when operating the device offline.
ATI Integrated Card Test ResultsMobility Radeon HD 4200 showed that it is capable of playing modern games with a comfortable FPS value and at a resolution of 1024x768. The closest competitor to this video card is the Intel GMA 4500MHD integrated graphics, which is inferior in performance to the considered Radeon model.
Testing in games
Определенно точно можно сказать, что карта не ways to ensure consistently high FPS in modern games. But the games that came out in 2004 and 2005, it is able to “pull”. At a minimum, FEAR’s popular shooter of the time on average graphics settings will show an average of 23 FPS. The high settings of the same FEAR are "non-playable" on this chart. About the game, released in the period 2006-2009 in general can not speak. The system with this video card can only pull the Devil May Cry game at low settings with more or less normal FPS (about 20 frames per second), but even then artifacts and "braking" in games are not excluded. But for popular shooters like Crysis or Battlefield, the ATI Mobility Radeon HD 4200 speed will not be enough. Only old and undemanding games will go on systems with this video card.
Laptops based on this adapter
Among the laptops working on the basis of this chip, the most successful are the models:
- HP ProBook 6545b with an AMD Turion II processor and 4 GB of RAM.
- Toshiba Satellite C650D with an AMD Athlon II Dual-Core processor and 3 GB of RAM.
- Asus K51AE with an AMD V-Series M120 processor and 2 GB of RAM.
- HP Compaq 625 with AMD Turion II Ultra CPU and 3 GB of RAM.
All these models were not created for games, they were positioned as office or home solutions for work and surfing the Internet, no more.
Conclusion
This integrated chip in the processor core was notthe best solution at the time of release, and especially did not become after them. Now it is impossible to buy it separately, you can only find old broken or even working laptops with this chip. Now they are no longer produced and sold only by hand.
