【 Weak current College 】 purchase video 5 big mistakes

Myth one: buy BGA memory video card

Current video main memory package divided into two TSOP. Use the most is the TSOP package graphics memory particles, because of its mature technology, low-cost, and therefore subject to many manufacturers of all ages. However for cost, cost considerations, most manufacturers only in some must adopt the high-frequency video MicroBGA packaging graphics memory. This package video memory chip PIN feet in the lower portion of the BGA packaging of IC can install 120 ~ 665 a PIN, connector, electrical properties are also not vulnerable PIN between electromagnetic signal interference. The benefits of using MicroBGA except electrical properties, thermal performance, there are distinct advantages. But from a performance perspective, the TSOP package graphics memory and graphics package MicroBGA and no gaps. While some manufacturers selling in order to pursue, in some low-end card also uses a slow MBGA graphics memory, for example in the use of 5ns GeForceFX5200 MBGA graphics memory, instead of such as choice and match 3.3ns even higher speed TSOP package graphics video card.

Myth two: RAM better

Many of my friends purchase a video card, always ask this video card is 64 MB of nor MB? this is the memory capacity. Current mainstream video cards are basically have 64MB or even 256MB 128MB. Video memory to system memory, the capacity of nature is bigger and better. But sometimes the video memory is not better, for different schemas, the different capabilities of the graphics core, the memory capacity requirements. Data processing power powerful graphics core, when used as anti-aliasing and other extra features to improve picture quality, you need to use more video memory, but for some low end graphics card, because the schema restrictions, even if you increase the memory capacity is not available to a significant increase in performance, more capacity can only increase the cost even more. For example, MX440 does not need MB graphics memory. But like GeForceFX5600, such considerable Radeon9550 strong core graphics, it's a good idea to mix 128MB capacity of video memory. For the game, you need at least Farcry MB graphics memory 3D game in General, such as the CS, 64MB graphics will be able to fully adjust the picture quality of CS to the best.

Myth three: the heat sink to big, fancy

Early video chip heat sink is a very simple heatsink. But now with the chip thermal growing by the day, the video card heatsink is also not only area more niaoqianghuanpao bigger and more powerful, fan, even the cold water is used. Like litai "hood", ASUS dual-fan, Rainbow of heat pipe and so on. As manufacturers, heat large, Tuxedo has also become a selling point. But the blind pursuit of radiator shape, not paying attention to the heat sink material as well as the real thermal effect, often counterproductive. There are many manufacturers of graphics look the heatsink is large enough for the spectacular enough, but the actual use effect is very bad. There are some video card with the gold of the extensive heat sink, but look closely, you'll find these fins have actually and video memory can contact, heat dissipation. In addition, a few manufacturers have to GPU heatsink with exaggerated, the key is, in most cases, these products are designed not to cross the border, but also to catch up with the product cycle, but to use a large heat sink to cover up the video of heat-related design flaws. Results market formed a circle, the radiator is small products but doubts is problematic, and finally eat dirt, or cut the odds users.

Myth 4: graphics 2D effects advance

The perspective from chip, current display Chip 2D output difference is very small, high speed of the RAMDAC module ensures precise DAC and signal stability. However, the video signal output before low pass filtering circuit can be an important component of shoddy work. NV and ATi's public Edition card for LPT circuit has a set of guiding design, but if the manufacturer does not follow the design of materials, resulting in 2D output problems. But that kind of put the filter capacitance of whole heap in the VGA port nearby is also not a good design, therefore, must not just listen to the so-called master of the low pass filter expression. If you want to guarantee equivalent 2D effects, be sure to buy the full version of manufacturing large public produced video card.

Myth 5: SMD capacitor must be the best

Capacitors, have always been decided a good Board performance and stability. The fundamental role of the capacitor is generally used for filtering, there are also used to stabilize the IC supply voltage voltage capacitor. The current frequency with the graphics chip, the increasing power consumption, at the request of the capacitor is getting higher and higher. In addition, the capacitor in the circuit is a certain resistance, if the power supply module with some low equivalent capacitance of the tandem of resistance, the GPU and memory have access to adequate current. At present, in various forums there is an unusual phenomenon that is on the SMD capacitor of idolatry, saw the Board on the use of plug-ins for capacitance reviled. This is clearly an abnormal psychology, this has also led manufacturers have to meet this abnormal state of mind, you will have excellent quality capacitance of Sanyo plug-in into the garbage SMD capacitor, but caused a decline in the quality of the video card.
