In the motherboard of Intel 810/815 or VIA 693A / 694X, we can often learn from the introduction to its own sound card is a soft sound card, which is generally compliant with the AC'97 standard, called AC'97 soft Sound card. In people's conventional understanding, AC'97 is synonymous with soft sound cards, unable to connect with high performance, and a noun for low-end integration motherboard. But I am watching a high-grade sound card, and I also indicate that this sound card is the standard of AC'97. Is this price that the high-grade sound card is not a soft sound card?
The reason is this: the so-called AC'97 soft sound card, just integrates a digital analog signal conversion chip on the motherboard, and the true sound card is integrated into the North Bridge, which has increased the work burden of the CPU. The so-called AC'97 hard sound card is integrated with a sound card chip on the motherboard. This sound card chip provides independent sound processing, and eventually outputs analog sound signal. This hardware sound card chip is relatively expensive than the soft sound card, so there will be a lot of reasons why it is also indicative of integrated Ac'97 standard sound card but the price is expensive. Numerous users buy motherboards that integrate AC'97 sound cards, but I will have to tell you that the protection of your investment and makes full use, it is recommended to use a hard sound card. Especially for those players who love 3D games and music enthusiasts to buy integration AC'97 hard sound cards are the most affordable choice. We made a trial in Haoxin AE25 integrated with the AC'97 hard sound card (CMI8738). The graphics card used in the experiment were the demon g 7600. In Quake3 we found that AE25 was extremely high at 1024x768 resolution and 800x600 resolution. It seems that the integrated hard sound card has played a small role in improving microscopic system, which greatly saves CPU resources, making CPUs more focused on processing with other information. And a motherboard integrated with a hard sound card is different from a price of the AC'97 sound card.
Another reason I recommend to buy an integrated Ac'97 hard card is that the AC'97 sound card is very dependent on the CPU for the process of the AC'97 sound card. It also takes a lot of CPU resources to the CPU. 3D games. Therefore, the burden on the CPU has greatly increased, and its FPS is not ideal. Its cmi8738 and the sound quality of the AC'97 soft sound card cannot be compared, and the CMI8738 does not say that the 6-channel support does not say, light listening to its clear, the transparent sound quality is enough to put the AC'97 uncomfortable noise far throws far away The back.
How do you feel after reading the above explains? Do you agree with my opinion? Finally, it is recommended to be more famous sound card chip: Best MIDI chip: YMF744; low-cost home theater chip: FM801; low price multifaceted chip: CMI8738 also has low-end products of innovative companies - Vibra 128 and PCI 128D; hero is late Chip - S90 and V1. These are quite a good hardware sound card chip.
