AMD has extended its line-up of mobile GPUs with a few brand-new models filed under its latest class of Radeon: the HD 8000M-series. The new chips deliver better performance, but are expected to do so with reduced power consumption, lower thermals and prices similar to their HD 7000M-based predecessors.
A Radeon HD 8700M trounces a GeForce 650M G5 in a variety
of internal (i.e. possibly somewhat exaggerated) AMD benchmarks.
The new line-up will feature an entirely 28nm-based Graphics Core Next (GCN) architecture. It's interesting to note this is not exactly a die shrink, as AMD's highest-end 7000M offerings were already 28nm; however, most of its 7000M line-up remains 40nm. Being GCN-based means all HD 8000M models will feature full Direct X 11.1 support and utilize ZeroCore, a technology which essentially powers down unused cores in an effort to save energy.
Equipped with a Radeon HD 8555M GPU, the Asus Vivobook U38DT currently being sold in Germany is the first notebook to see 8000M-series silicon. The 8500 series features an "up to" 650MHz core with 384 stream processors and the option of either GDDR3 @1125MHz or DDR3 @1000MHz.
Other GPUs set to be released soon include 8600M series models (384 stream processors, 725/1125MHz), 8700 series models (384 stream processors, 850/1125MHz) and a higher-end 8700M series which boasts 640 stream processors, 700MHz core and exclusively uses GDDR5.
The highest-end models are likely to turn up in Q2, which will take aim at uncompromising gamers and enthusiasts.
The HD 7950 has 2048 SPUs, 128 TAUs and 32 ROPs. The only other ports are on the I/O panel where you'll find a dual DL-DVI connector, a single HDMI 1.4a port, and two mini-DisplayPort 1.2 sockets. Supports a max resolution of 2560x1600 on up to 3 monitors.
