Manufacturing process, manufacturing process of the display card and hp g56-106sa laptop keyboard
CPU, is to use a micron to measure the machining accuracy of. Graphics
manufacturing process in 1995 years, from 0.5 micron, 0.35 micron, 0.25
micron, 0.18 micron, 0.15 micron, 0.13 micron, 0.11 micron has been
developed to present the latest and nano.
The core frequency, refers to show the core work frequency, a bit like
CPU work main frequency. Here needs to point out that is not the core
frequency work on behalf of the graphics performance is strong. Such as
9600 pro core frequency up to 400 MHZ, more than 9800 pro 380 MHZ is
high, but the performance is stronger than 9800 pro absolute 9600 pro.
In the same level of chip, the core of high frequency is better hp g56-107sa laptop keyboard
, and improve the performance of some core frequency is one of the ways card overclocking.
Memory usage frequency, memory card in the work frequency, with MHz
(MHz) as the unit. Video memory frequency to a certain extent reflects
the speed of the memory. Video memory frequency with the type of
memory, performance different and different, DDR3 memory is the most
widely used high-end graphics memory type. In addition, different memory
can provide the memory usage frequency also difference is very big,
basically have 400 MHZ, 500 MHZ, 600 MHZ, 650 MHZ, high-end products and
800 MHZ, 1200 MHZ, 1600 MHZ, or even higher. Nvidia GeForce 8700 m GT
and above type of memory usage frequency has reached 800 MHZ.
Render pipeline, also known as the rendering pipeline, it is display chip hp g56-108sa laptop keyboard
internal graphics processing signal independent parallel processing
unit. The number of rendering pipeline is decided to display chip
performance and grades of one of the most important parameters in the
same graphics core frequency, more rendering pipeline means greater
pixel fill rate and grain filling rate, from graphics rendering line
number can be roughly tell graphics performance high and low class. The
number of rendering pipeline is generally "pixel rendering pipeline ×
the number of each line texture unit quantity" to show. For example,
GeForce 6800 rendering pipeline is 12 multiply one, he says it has 12 a
pixel rendering pipeline, each contains 1 grain filling pipe.
RAMDAC, decided to refresh the discretion of the frequency, MHz for hp g56-110sl laptop keyboard
unit, and display "bandwidth" meaning approximate. Its operating speed
is high, the more wide frequency band, high resolution of the picture
quality is better. This value determines the enough memory, graphics in
support of the highest resolution and refresh rate. Such as: if you
want to in the resolution of 1024 x 768 to 85 hz resolution, RAMDAC
rate is at least 1024 x 768 x 85 x 1.344 ÷ 1.06 ≈ 90 MHZ. At present
the mainstream graphics RAMDAC can reach 350 MHZ and 400 MHZ.
DirectX by Microsoft development USES a wide range of API, include
Direct Graphics (Direct 3 d + Direct Draw), Direct Input, Direct Play,
Direct Sound, Direct Show, Direct Setup, Direct Media Objects, and
other components hp g56-113sa laptop keyboard
, and is a complete set of multimedia interface scheme. It should be
said that the public begin to pay close attention to mobile video card
products its corresponding part DirectX has basic is the DirectX 7.0
began to dive. On the market now DirectX 7.0 related products have
already out of season. The latest DirectX10, can provide a new dynamic
program flow control, displacement mapping and render target, times of
surface scattering, soft shadows, environment and ground shadow, global
illumination and other new technical characteristics, showing a sense
of reality, compared to the first all version if use "qualitative leap"
to describe it too much.
