Multi-GPU configurations using two or more graphics cards is one solution to boost gaming performance. This solution is commonly used by gamers and regular users if a graphics card is not sufficient to run their favorite games with a comfortable frame rate in the eyes.
For those of you who like to play games of the convenience factor is one important factor when gaming bet.
Currently there are two multi-GPU technology from two different manufacturers, an AMD graphics card with Crossfire and Nvidia with scalable Link Interface (SLI). Basically, they using the same technology that combines the capabilities of two or more graphics cards so that the frame rate on games or graphics applications can be increased. Of course, to use multi-GPU configurations required several conditions such as a motherboard that supports multi-GPU configurations, power supply with sufficient power output, and of course the driver with multi-GPU profile right.
Multi-GPU configurations generally use two add-on graphics card or more. But do you know if a multi-GPU configurations can be done using the add-on graphics card and integrated graphics card (onboard)? Both AMD and NVIDIA both have this technology, although it seems that only
AMD that still uses the multi-GPU technology like this.
Hybrid Crossfire is a multi-GPU configurations using onboard graphics card on the motherboard and graphics card add-on. Onboard graphics card that can be used as the HD 4290 on AMD 890GX chipset or HD 3300 to HD AMD 790GX chipset. While the type of add-on graphics card used is usually derived from entry-level classes such as HD 5450.
Continuing with Hybrid Crossfire technology, AMD today introduced the multi-GPU technology called AMD Dual Graphics. Basically how the AMD Dual Graphics are not much different from the Hybrid Crossfire. The difference is the graphics card is now replaced onboard integrated
graphics card on AMD’s APU Llano. This technology already come on the AMD platform Llano A-Series desktop and mobile versions. Although AMD Dual Graphics technologies promise to improve gaming performance, there are some limits on this technology. One of them is the limited types of add-on graphics cards that can be used. Besides AMD Dual Graphics is more optimal if used in graphics applications and games based tenologi DirectX 10 and 11.
By default, Llano wants to be the primary output. So, when you configure your BIOS, set up Windows, and get drivers installed, AMD says use the APU’s outputs. If there’s a discrete card installed, CrossFire gets enabled automatically. At that point you have to install the latest Application Profiles patch, disable CrossFire, shut the system down, and switch over to the discrete outputs. From then on, you won’t see a video signal until Windows loads up. Enable CrossFire, reboot again, and then you should be able to use Dual Graphics. At least once you get there, a Dual Graphics-enabled configuration makes Eyefinity a possibility. Using display outputs from each graphics processor, you can connect three or more displays
in an extended desktop configuration. Just be careful with the outputs you choose. Some motherboard vendors are implementing single-link DVI connectors, while others use dual-link. Of the boards we have here, they all also come with VGA and HDMI; only Gigabyte gives you
DisplayPort connectivity, too.
To run the configuration AMD Dual Graphics (in this case the desktop version) is required add-on graphics cards and AMD’s integrated graphics card on AMD’s APU Llano A-Series. There are two options for an integrated graphics card that is HD-Series 6550D in the A8 in the
A6 and HD-Series 6530D. While the add-on graphics cards that can be used is the AMD HD 6000 series with the highest type, HD 6670. For more details on the configuration of the AMD Dual Graphics, you can see the table below.
Seen in the table above, the configuration of the AMD Dual Graphics are creating a new type of graphics card. As seen on the combination of AMD’s HD 6670 and HD 6550D which creates graphics card called HD 6690D2. HD 6690D2 name seems to indicate the performance of this
graphics card will be above the HD 6670.
Enabling Dual AMD Desktop Graphics version with AMD Dual Graphics Enables feature is quite easy.
Here are the steps:
• First make sure you use the monitor cable connector mounted on a display located on the motherboard.
• Don’t forget to install the add-on graphics card on PCI Express x16 slot before turning on the system.
• Make sure the option “Dual Graphics / Surround View” on the motherboard’s BIOS menu is actived. This option usually appears in the BIOS menu after you install the add-on graphics card.
• The next step is to install the graphics card drivers and reboot your system.
• If the option “Enable Crossfire” on AMD’s Vision Engine Control Center already actived, then a check mark will show on AMD Dual-Graphics has been actived.
• This is the GPU-Z screenshot of the application when AMD Dual Graphics is in active condition.
Using multi-GPU configurations AMD Dual Graphics really delivers improved performance enough. As an example let us look at the performance of the HD 6670 + HD 6550D 6690D2 or the HD. 6690D2 HD performance not only exceeds the performance of HD 6550D but also exceeded the performance of the HD 6670. HD 6690D2 name seems quite appropriate given the performance that was carried over the HD 6670.
Overall, the use of AMD Dual Graphics configuration capable of delivering up to 30% performance improvement over the performance of the add-on graphics card, the graphics application or a particular game.
The results of the above test was also revealed interesting facts. As we mentioned in previous pages, AMD’s Dual Graphics features caused more optimal use in graphics applications or games that use DirectX 10 and 11. In DirectX 9 games, using a configuration makes the AMD Dual Graphics performance is not as firm as if using an add-on graphics card. If most of the games you play are still based on DirectX 9, using an add-on graphics card is a more appropriate choice. AMD Dual Graphics configuration is more appropriate to be used in DirectX 10 games and 11.
An improved performance feature offered by AMD Dual Graphics is quite tempting. But keep in mind to use this feature required graphics card add-on extra that means you have to spend more. Besides AMD Dual Graphics is also more optimal in DirectX 10 games and 11. Yet today
there are many game titles that use DirectX 9 technology.
The configuration of the AMD Dual Graphics is one attractive option to boost the performance of AMD’s GPU at APU Llano A-Series desktop version in addition to overclock the system memory.
