The main types of
The onboard cache can be divided into two types: integrated into the display buffer inside the Northbridge chip and a separate display cache onboard, the market most of the onboard display cache the motherboard is the former, such as the common 865G / 845GE motherboard; while the latter is relatively rare, such as elite "game Titans" series of motherboards, onboard the SIS Xabre 200 independent display cache, and has 64MB of dedicated graphics memory. Motherboard onboard display cache history has a very long history, from the earlier VIA chipset MVP4 later Intel's 810 series, 815 series, 845GL / 845G / 845GV / 845GE, 865G / 865GV and the upcoming 910GL / 915G / 915GL / 915GV chipsets and other integrated graphics cache. Intel also is relying on the integrated display buffer, only occupy a larger share of the graphics chip market. At present the major motherboard manufacturers have integrated graphics chipset motherboards cache, and integrated motherboard all motherboard makers also have a corresponding. Maker Intel platform integrated chipset Intel, VIA, SIS, ATI and other manufacturers AMD platform chipset has integrated VIA, SIS, NVIDIA, and so on. From a performance point, Intel platform showed the highest cache performance ATI's Radeon 9100 IGP chipset, and AMD platforms showed the highest cache performance is NVIDIA's nForce2 IGP chipset.
mainstream
of dedicated graphics memory
These are the onboard memory of the past, now, more onboard memory independent memory particles to the board, for example, now more popular AMD 785G chipset are integrated directly on the motherboard memory particles, generally 128M. In contrast, the performance of such a motherboard integrated graphics memory is generally much stronger than sharing graphics performance. Thus, the high cost motherboard motherboard onboard memory particles, it is a good choice.
However, onboard graphics will occupy part of the system memory as video memory, causing confusion for some users of Memory "less" of. Graphics do not want to take up memory, you should configure the graphics card or motherboard with onboard graphics memory.
Now the graphics card manufacturers to produce more shared main memory, graphics card, so put on some graphics cards carrying memory PCB called the "on-board memory," shared main memory of memory called "shared memory."
Unika UR780GX motherboard
always attached importance to the integration platform to launch a variety of Unika in the AMD 780G chipset based products, and recently for HTPC introduced a user using M-ATX board design new products --UR780GX, in addition to the video output interface with HDMI / VGA / DVI, including, also onboard 128M DDR2 memory, allowing users to enjoy high-definition movies HTPC's You can play mainstream games. Then, in the popular online games / 3D games it in the end to have the kind of performance? Relative terms it is not onboard 780G graphics memory how about the performance boost it? Unika UR780GX [quote parameter picture] motherboard uses a red PCB , M-ATX board design, fits easily into a small HTPC chassis. Based on AMD 780G + SB700 motherboard chipset supports AMD Socket AM2 / AM2 + interface processor.
