The market of mobile graphics adapters do not like the desktop market. Mobile analogues appear later and are generally inferior in terms of productivity of their desktop counterparts. Mobile boosters are not sold separately and do not have the colorful packages. Prepare a comparative review of the modern mobile graphics adapters is difficult. This is a desktop segment to build a test stand and in turn to install video card there. One mobile phone adapter - one laptop. The laptop, which has its own characteristics. Choose a laptop with the same processors, but different graphics cards pretty hard. It is for this reason that virtually no one takes the mobile video reviews. Today we have the opportunity to compare the two solutions company AMD. Graphics Adapters ATI Mobility Radeon HD 4850 and HD 3850, as expected under the laws of the genre, came out later on the desktop counterparts. Nevertheless, they were welcome. Functionally, they are no different from the desktop accelerators. However, Mobility Radeon HD 4850 runs at 500/850 MHz for the chip and memory, respectively, from the desktop version of the formula is equal to the frequency 625/2000 MHz. Accelerator Mobility Radeon HD 3850 was instead 670/828 MHz for the chip and the memory of all 480/600 MHz. Journalists from resource HEXUS.net tested two notebook MSI GT725 and GT735. Model GT725 received card ATI Mobility Radeon HD 4850 512 MB and processor support from Intel Mobile Core 2 Duo P9500, which runs at 2, 53 GHz. Graphic adapter Mobility Radeon HD 3850 512 MB and Processor AMD Turion Ultra ZM-82 (2, 2 GHz) were present in the product GT735. In addition, they added the results of a laptop Zepto Nox A15, which was a chip Intel Mobile Core 2 Duo P8400 (2, 26 GHz) and the adapter NVIDIA GeForce 9600M GT. Gaming applications only two - Enemy Territory:Quake Wars and Call of Duty 4:Modern Warfare. In the game Enemy Territory adapter Radeon HD 3850 yields even GeForce 9600M GT, the reason is very simple - a weak processor support from the Turion Ultra ZM-82. Graphics Card Mobility Radeon HD 4850 is 34% productive GeForce 9600M GT and 83% ahead of Radeon HD 3850. The whole blame low CPU AMD. In the same conditions, video card Radeon HD 3850 would show a very different result. shooter Call of Duty 4 less dependent on the performance of the mainframe. Do adapter Radeon HD 3850 and GeForce 9600M GT almost equal number of frames per second. And the Radeon HD 4850 Radeon HD 3850 is ahead by 62%. the conclusion that follows. While processor support AMD mobile processors is clearly not sufficient to demonstrate the capabilities of modern mobile accelerators. Unfortunately, a more or less fair outcomes is virtually impossible. You can certainly try to find a card in the MXM modules and install them in a special desktop motherboard. The question is one where ? Where are these boards ? For this reason, can only be satisfied by the data that exists. And навскидку assess the level of performance of different wireless cards.
