However, the 8790M can potentially draw less power when idle (if not disabled by Enduro). The power consumption should be slightly higher than the previous 7690M chip when under load (2 Watt difference according to the desktop setup from Techreport).

Additionally, it now allows audio to output simultaneously and in parallel to multiple devices with the new Discrete Digital Multipoint Audio (DDMA) feature.

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). 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. PowerTune allows automatic overclocking and underclocking of the graphics card as long as the GPU is within its TDP limit.

Other features of the 8700M 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. Furthermore, the 8790M can directly support up to 2 connected monitors using Eyefinity Technology if Enduro is disabled. Called Enduro, the technology supersedes AMD's Dynamic Switchable Graphics and is similar to Nvidia's Optimus. The 8700M series also supports automatic graphics switching between the integrated GPU and discrete GPU. Multi-View Codec (MVC) and MPEG-4 part 2 (DivX, xVid) HD videos are now compatible as well. Compared to old TeraScale 2 chips, the GCN-based Mars architecture offers improved performance in this framework.įeatures of the 8790M include video decoding via UVD3 for decoding MPEG-4 AVC/H.264, VC-1, MPEG-2, and Flash directly from the AMD GPU. The 384 shaders can be used with OpenCL 1.2 for general-purpose calculations (as 6 compute units). Most games of 2013 can be played fluently in medium or high details and the WXGA resolution of 1366 x 768 pixels. The performance of the Radeon HD 8790M is similar to the Nvidia GeForce GTX 660M or GT 750M and therefore in the upper mid-range category. The core is clocked at 850 MHz (900 MHz Boost) with GDDR5 VRAM at 1125 MHz (4500 MHz effective). It is based on the Mars chip (28nm GCN architecture) with 384 shader cores, 24 TMUs, and 8 ROPs. The AMD Radeon HD 8790M (sometimes known as the ATI Mobility Radeon HD 8790) is a DirectX 11.1 graphics card for laptops. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.3D Printing, 5G, Accessory, AI, Alder Lake, AMD, Android, Apple, ARM, Audio, Benchmark, Biotech, Business, Camera, Cannon Lake, Cezanne (Zen 3), Charts, Chinese Tech, Chromebook, Coffee Lake, Comet Lake, Console, Convertible / 2-in-1, Cryptocurrency, Cyberlaw, Deal, Desktop, E-Mobility, Education, Exclusive, Fail, Foldable, Gadget, Galaxy Note, Galaxy S, Gamecheck, Gaming, Geforce, Google Pixel, GPU, How To, Ice Lake, Intel, Intel Evo, Internet of Things (IoT), iOS, iPad, iPad Pro, iPhone, Jasper Lake, Lakefield, Laptop, Launch, Leaks / Rumors, Linux / Unix, List, Lucienne (Zen 2), MacBook, Mini PC, Monitor, MSI, OnePlus, Opinion, Phablet, Radeon, Raptor Lake, Renoir, Review Snippet, Rocket Lake, Ryzen (Zen), Science, Security, Single-Board Computer (SBC), Smart Home, Smartphone, Smartwatch, Software, Storage, Tablet, ThinkPad, Thunderbolt, Tiger Lake, Touchscreen, Ultrabook, Virtual Reality (VR) / Augmented Reality (AR), Wearable, Wi-Fi 7, Windows, Workstation, XPS, Zen 3 (Vermeer), Zen 4ĪMD Radeon HD 8790M ► remove from comparison ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. It is measured in millions of texels applied in a second. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). This number is worked out by multiplying the total texture units by the core clock speed of the chip. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. It especially helps with anti-aliasing, HDR and high resolutions. The higher the bandwidth is, the faster the card will be in general. In the case of DDR RAM, the result should be multiplied by 2 again. It's calculated by multiplying the card's bus width by the speed of its memory. Memory Bandwidth: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second.
