After the beginning of the Radeon HD 7900 series Radeon HD around the model has completed 7950, followed shortly thereafter only entry-level variants based on the Radeon HD 7700 series, the middle segment, one of the Radeon HD since March 7800, the variations in The Radeon HD 7870 vs HD 7850 is available. On the so-called "Pitcairn" GPU-based cards can look forward to the full feature set of the Radeon HD 7900 and Malthus include innovations tested as zero core power, DirectX 11.1, to improved anisotropic filtering and much more. Only the number of execution units in vivid reduced and adjusted to the reference clock rates accordingly, we have the XFX Radeon HD 7870 Black Edition dual-fan, a factory overclocked version of Radeon HD 7870, lured for a detailed test to us.
The content of the Radeon HD 7870 packaging include the mandatory software and driver CD, a XFX Black Edition Case-Badge, a quick installation guide as well as various promotional materials. Also sets the XFX card has a DVI-HDMI
adapter and a CrossFire bridge, from which we will make on the next information is useful for that such a good and important sign Do Not disturb, I'm gaming" for domestic door manage protects versus unexpected guests, on the other cables, such as PCIe Molex adapter, is dispensed with entirely.
AMD's Radeon HD 7800 family currently consists of two models: Radeon HD 7870 and Radeon HD 7850th Both offspring are based on the 212 mm ² Pitcairn GPU, which has a 28 nm manufacturing technology underlying, and manufactured by TSMC partner, at about 2.8 billion transistors, the new AMD graphics core next-architecture and wants to put in force in the coming years, other products. These are authorized from longtime VLIW well and most important design with more dimensional Shader units and relies on a mix of scalar and vector units, this will raise the utilization of the shaders are raised and total operation the all GPU more efficiently.
Once the graphics wood registers this, GPU and memory are the several card and disabled it cadaver only the power consumption of the PCIe interface, also the fan blocks after that. This works well when using CrossFire configurations in which unused graphics accelerators are switched off and so much energy is saved, the maximum power consumption of AMD developers are using 175 watts or 130 watts on.
