How much memory do I need? One of the most frequently asked questions. The solution for this is 128MB would be sufficient. 64MB - not enough, with some exceptions, when an additional graphics card uses system memory usage, such as HyperMemory (ATI) and TurboCache (Nvidia). Demanding gamers need a volume of 256MB video adapter easier to work at high resolutions.
H Name of the technology speaks for itself, i.e. card uses the main memory of the laptop (RAM). Practically, the large difference between HyperMemory (ATI) and TurboCache (Nvidia) is not, but some prefer Nvidia. Be careful! The maximum amount of main memory used by the video card depends on the amount of memory itself, i.e. than its larger, the larger the volume can use the card. Always check how much dedicated video memory has a video card instead of selects from the system memory.
In recent months the world of portable computers has been a major boost, which also involved the narrowest scope of graphics chips: the release of new multimedia libraries of the Windows Vista operating system has accelerated the development of graphics cards capable of DirectX 10 support, and the more widespread use of optical drives compatible with the new Blu-Ray and HD-DVD has made it necessary to empower the GPU to decode the new high-definition video formats.
The market in a very short time has been literally flooded with new models that promise full compatibility with the new operating system from Redmond (and his very demanding Aero user interface) that allow hardware decoding of H.264, becoming the current standard in notebooks aimed at gaming and, more generally, digital entertainment.
It must be said, however, that not always this new generation of video cards have all the characteristics which we have just mentioned: the case of subsystems integrated video chipsets, which are currently lacking is support for DirectX 10 API set both decompression hardware MPEG-4, but is also the case for dedicated graphics card ATI Mobility Radeon X2300 and X2500, mounted on many notebook models and economic mainstream of the new generation. Even the ATI Mobility Radeon HD2300, unlike all other models in the series Mobility Radeon HD is not compatible with DirectX 10, although it is equipped with Avivo transcoder (as witnessed by the acronym HD High Definition).
Types of GPU for notebook graphics cards are not all equal
We can define three categories of video cards for notebooks:
- Dedicated (Nvidia Geforce - ATI Mobility Radeon)
- Integrated (Intel GMA and others)
- Professional (Nvidia Quadro - ATI Mobility FireGL)
The mobile workstation graphics cards, less widespread and more expensive than their gaming counterparts. It must be said that the chip in the graphics card Quadro / FireGL are the same as the GeForce / Radeon, the difference in hardware is often given only on the type and amount of dedicated memory, the rest is just tweaking the software. In many cases it is possible and convenient, modding your video card Geforce Quadro-to-Radeon FireGL, to achieve significant performance improvements in editing programs and 3D modeling.
As for the integrated graphics chips, are obviously the cheapest and therefore the least efficient, but as strengths have a smaller footprint, low consumption and a minimum level of heat dissipation, as well as a price close to zero because they are included in the Northbridge chipset. Advantages that make them the most suitable products for use in ultra-light notebook and entry-level, but are also recommended for those who prefer portability and autonomy and no plans to use the laptop for 3D games.
Graphic memory:
The amount of installed RAM is often the first parameter that evaluates the average user in choosing a video card. This is definitely a feature that affects the overall performance of the GPU, but it is not the only parameter to consider. The main role is played completely from the graph, which is the basis of performance pure video card. Just read the name of the GPU: 8600M GT, HD 2600 every model is almost always a different chip. The models are different then for the type and amount of memory installed, and the frequency imposed by the manufacturers. The GDDR3 is better than DDR2 performance, because they travel at higher frequencies, are made by adopting the most modern production processes that reduce consumption, and also allow overclock more motivated.
So rather than see how much RAM is installed on our mobile video card, try to find out what RAM is. The operation is often quite complex because a single type of graphics chip can be accompanied by different memories.
