In late 2005, ATI officially introduced a new generation of its chips under the name ATI Radeon X1000 Family. Key enhancements to the architecture provided by chip series ATI X1000, can be described as supporting Shader Model 3.0 and the new memory controller, which is made with the use of 512-bit (2 x 256) “ring” bus (Ring Bus). Moreover, technology has AVIVO. This functionality allows the ATI X1000 graphic cards to improve quality and productivity of working with video. An interesting and somewhat unusual, even for users was the possibility of withdrawal of multichannel audio content via HDMI using the built-sound decoder.
family of graphics adapters HD2000, HD3000 and HD4000 also receive audio decoder ATI HDMI Audio. Numerous forums explaining to customers how to deal with any emerging issues with this decoder. For example, the most common problem associated with the disappearance of the system after installing the sound drivers for the sound chip card. Having said that, it caused a lot of emotions of the user, with the negative. The problem was that the ATI HDMI Audio decoder detects the operating system as the main audio device and audio output at HDMI.Takaya problem is solved with a basic sound card destination device by default.
Many simply turn off ATI HDMI Audio for its tranquility, and, as it turned out to do. Our colleagues from the resource Hardware-Infos.com spent entertaining study. They assembled a test stand, which was staffed by a processor Core 2 Quad 9450, 4 GB of RAM and a graphics card ATI Radeon HD 4870 (Catalyst 9.6). As tools for measuring productivity, they used the game Crysis Warhead, Far Cry 2, GRAW 2, GTA IV, HAWX and Stalker: Clear Sky. Testing took place in the high-resolution modes and heavy, to ensure the maximum load on the graphics subsystem. Then in Device Manager, activate and deactivate ATI HDMI Audio.
As a result, was able to detect a performance improvement of up to 5% in the off decoder ATI HDMI Audio. Most responsive to the deactivation High Definition Audio emerged game GTA IV, HAWX and GRAW 2. Thus, removing the additional burden on the processing of sound from GPU, you can get a small increment. Growth, which is equivalent to a small acceleration.
German readers immediately raised several questions the authors of the study. They are most interested in the reduction of energy consumption and emissions of heat graphics chip, with the deactivation of High Definition Audio. Another, it was important to know about the possibility of testing, but with mobile graphics cards. Perhaps the answers to these questions will not be, but that needs to be done to improve productivity in 3D is already known.
Materials:
– Sapphire Radeon HD3870 – AMD does not give up!
– AMD Radeon HD 4770 – resistance is useless!
– XFX Radeon HD 4890 – the first test new GPU AMD RV790.
