The new AMD 880G chipset is based on Radeon HD 4250 graphics engine, which is a slower version of the graphics engine used on AMD 890GX (Radeon HD 4290). This way 880G-based motherboards are cheaper than 890GX-based ones. Let’s take a look at ASRock 880GXH/USB3, which brings USB 3.0 ports.
In the table below we provide a comparison between AMD 880G and other chipsets with integrated graphics from AMD.
|Chipset||AMD 890GX||AMD 880G||AMD 785G||AMD 780G||AMD 760G||AMD 790GX|
|GPU Clock||700 MHz||560 MHz||500 MHz||500 MHz||350 MHz||700 MHz|
|Engine||HD 4290||HD 4250||HD 4200||HD 3200||3000||HD 3300|
|South Bridge Chip||SB850||SB710||SB710||SB700||SB710||SB750|
|USB 2.0 Ports||14||12||12||12||12||12|
|RAID||0, 1, 5, 10||0, 1, 10||0, 1, 10||0, 1, 10||0, 1, 10||0, 1, 5, 10|
|ATA-133 Ports||1 (2 devices)||1 (2 devices)||1 (2 devices)||1 (2 devices)||1 (2 devices)||1 (2 devices)|
Other chipsets with on-board video from AMD include AMD 690V, AMD 690G, AMD 740G and AMD 780V. AMD 690V, AMD 690G and AMD 740G are based on a DirectX 9 graphics engine, while AMD 780V is based on a DirectX 10 one. AMD 780V is based on Radeon HD 3100 engine, which runs at 400 MHz – clock is the main difference between HD 3100, HD 3200 and HD 3300 engines.
As you may know by now, on systems with integrated video the video memory is achieved by stealing part of the main RAM. Chipsets from AMD have a feature called SidePort, which is an optional memory chip soldered on the motherboard in order to increase video memory. The portrayed motherboard doesn’t have this feature.
Now let’s take an in-depth look at ASRock 880GXH/USB3 motherboard.
