It is built on the architecture of Fermi and has full support for DirectX 11 Shader Model 5.0. Graphics Card GeForce GTX 480M has 352 cores CUDA, operating at a frequency of 850 MHz. It can be compared to the GTX 465 card for desktop computers, but with lower frequency and power-optimized. GeForce GTX 480M has 2 GB of fast memory GDDR5. This graphics card from NVIDIA supports technologies such as PhysX, 2-Way SLI, CUDA, PureVideo HD 1080p, PCI Express 2.0, OpenGL 3.2 and Dual-link DVI with HDCP. It is also fully compatible with the requirements of the operating system Microsoft Windows 7.
Graphics Card NVIDIA GeForce GTX 480M focused on high-performance mobile PC designed for the most demanding gamers. Direct competitor in the market NVIDIA is the production of AMD / ATI. First of all, this line of graphics cards ATI Mobility Radeon HD 5000 series, which debuted in early 2010. The architecture of these cards created by array of unified processors that provide processing of different kinds of data. Top product of this series is the graphics card Mobility Radeon HD 5870, which is essentially a modification of the "desktop" accelerator Radeon HD 5770 only with a lower frequency.
This card has a core frequency 700 MHz and memory frequency of 4000 MHz. It supports DirectX 11 hardware. Memory Interface Mobility Radeon HD 5870 has two 64-bit controllers that lead to a 128-bit memory bus. As a result, access to a maximum of 1024 MB of DDR3 or GDDR5 (512 MB GDDR3). Performance of the card lets you run on your laptop virtually all modern computer games and graphics applications running at the highest resolution and most detailed drawing. All video series Mobility Radeon HD 5000 has an improved video processor for decoding high-definition video (HD). Because high power consumption Card Mobility Radeon HD 5870 is only suitable for laptops with a good cooling system. At the same time very much reduced power consumption cards through the use of technology Memory Clock Scaling and Clock Gating. When choosing a laptop with some graphics should, above all, to decide which tasks are in front of the mobile device. If the laptop will only run office applications, the need for expensive graphics card just disappears. Powerful graphics devices as needed for computer games and work in graphic applications. It is worth to spend money on a laptop with a modern video card that has high performance and capable of solve various problems. Source: Electronics-review.ru – tests and reviews of computer hardware
