AMD Radeon HD 8830M

AMD Radeon HD 8830M

The AMD Radeon HD 8830M is a 28nm DirectX 11 graphics card based on the GCN (Graphics Core Next) architecture. Built primarily for medium-sized laptops, the card is positioned in the lower performance category as of 2013. Compared to the similar Radeon HD 7850M, the 8830M offers slightly reduced clock speeds and significantly slower DDR3 memory.

The design of the Radeon 8800M series has its roots to the Cape Verde chip as found, for example, on the desktop Radeon HD 7770 with 640 1D shader cores and 40 texture units. However, the core clock of the 8830M is only 575 MHz (Boost up to 625 MHz) versus the 1000 MHz of the HD 7770.

As a result of the low clock rate and the DDR3 memory, the 8830M is the slowest model of the 8800M series and competes with the GeForce GT 645M. Current and demanding games like Far Cry 3 should run fluently in medium resolutions and detail settings.

The 640 shaders can be used with OpenCL 1.2 for general-purpose calculations.

Features of the 8830M include video decoding via UVD3 for decoding MPEG-4 AVC/H.264, VC-1, MPEG-2, and Flash directly from the AMD GPU. Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos are now compatible as well.

The 8800M series also supports automatic graphics switching between the integrated GPU and discrete GPU. Called Enduro, the technology supersedes AMD's Dynamic Switchable Graphics and is similar to Nvidia's Optimus. Furthermore, the 8830M can directly support up to 6 connected monitors using Eyefinity Technology if Enduro is disabled.

Other features of the 8800M series include ZeroCore for reducing power consumption when the display is turned off and Power Gating to power down areas of the chip that are not used. PowerTune allows automatic overclocking and underclocking of the graphics card as long as the GPU is within its TDP limit. For example, the chip may be underclocked when running FurMark and OCCT, but will overclock in certain games like Lost Planet, Crysis or Resident Evil 5.

The integrated HD audio processor is able to transmit HD Audio (TrueHD or DTS Master Audio) over HDMI and DisplayPort (e.g., for Blu-Ray videos). Additionally, it now allows audio to output simultaneously and in parallel to multiple devices with the new Discrete Digital Multipoint Audio (DDMA) feature.

Power consumption of the 8830M should be suited for laptops 15-inch or greater.
