What is the difference between a mobile platform and a desktop platform video card

Comparison of specification parameters

The author investigates dozens of of the market with independent graphics card game notebook, they are equipped with graphics cards generally in GTX more than 950M, the highest several have used GTX 980 desktop version. It is important to note here that the performance is not enough to run the mainstream game of the GTX 940M is not listed in the range of comparisons, strictly speaking, it does not belong to the category of game graphics. As a contrast to the desktop Platform graphics card we chose the previous generation of GTX 750Ti to GTX 980 between several products, the reason is not to choose a new generation of graphics products, the main reason is that the structure and performance differences too large, and the current market share is not high. The result of game test in database is also deficient, the reference significance is not big.

Compared with our familiar desktop graphics card more uniform specifications, the mobile graphics market is less transparent, Nvidia for OEMs and ODM vendors prepared a variety of video memory configuration graphics scheme, GTX 950M has GDDR3/GDDR5 two types of memory, two versions of the performance difference is quite obvious. In addition, the GTX 965M also has two core versions of the old and new, using the first and second generation Maxwell respectively. and the desktop graphics card on the relative stability of more than the public version of the video card only in the core frequency is different, did not appear and mobile graphics the same chaotic situation.

From the core, the desktop graphics card and the mobile version of the notebook used in many models are using the same symbol of the display core. For example, the mobile version of the GTX 950m/gtx 960M and GTX 750Ti uses a nearly uniform display core of specifications, just slightly different frequencies. And the same display of the core of the video card on the memory to show a great difference. Mobile video card because of its power consumption and heat of the strict control, so the memory frequency will be relatively low, so that the frequency of the gap between the memory bandwidth of the larger gap, the performance caused a certain impact.

Benchmark Performance Test

In order to test the results more meaningful, notebook side we choose to use I7-6700HQ game notebook for testing, desktop test platform we have chosen with the majority of the game is equipped with I7-6700HQ performance similar to the i5-6600k platform for testing.
