Mobility Radeon HD 5000 introduced: DirectX 11 from AMD for laptops
DirectX 11 goes mobile: AMD announced the launch of the Mobility Radeon HD 5000. The manufacturer also advertises best performance in power consumption, fps and multi monitoring. PC Games Hardware presents the details.
AMD's Radeon HD 5000 series conquers the notebook market. Thus all the features of the popular gaming graphics card family come to the mobile sector. AMd doesn't only wear the performance crown but also advertises features like DirectX 11, an improved performance to power consumption ratio and the multi display technology Ati Eyefinity. The new flagship of the product array, the Mobility Radeon HD 5870, is according to benchmarks made by AMD 30 to 50 percent faster than Nvidia's top dog Geforce GTX 280M - but as usual those results have to be taken with a pinch of salt. The chart below gives an overview of the whole series:
It's clearly visible: Actually the Mobility Radeon HD 5870 isn't a match even for the smallest desktop version of the HD 5000 series. Though both, the mobile and the desktop version, have 800 ALUs and 700 MHz chip frequency, the Mobility gets only 2 GHz fast GDDR5 memory (desktop: 2.300 MHz). Nevertheless the new graphics unit is fully useable for gaming and in matters of performance comparable to a Geforce 8800 GTX or a Radeon HD 4850. For the smaller variants AMD primarily reduces the number of active ALUs: The HD 5600/5700 series has 400 and the HD 5400 only 80 units - this is not really enough for modern high-end games.
The offered features are quite interesting, too: Besides DirectX 11 the Mobility Radeon HD 5000 offers UVD2, which enhances and accelerates HD videos - even for two streams simultaneously. Furthermore the high power consumption of the HD 4000 series has been dealt with and reduced noticeably. AMD notes an improvement of up to 50 percent. Ati Eyefinity, AMD's multi monitor technology, is also supported by the new chip - if the feature is available in form of the required display connectors, is up to the notebook manufacturers though.
Mobility Radeon HD 5650: First notebook test
Let's go to business. PC Games Hardware tested one of the first DirectX 11 notebooks. The Fire DTX from Deviltech uses the new middle-class in form of the Mobility Radeon HD 5650. In the benchmarks the device convinced with about 10 percent better performance than the predecessor HD 4650. For fans of image quality: The graphically impressive Supersampling Anti Aliasing is working well, too.
