The third netbook in our today’s test session is Asus Eee PC 1015B, which may be considered some kind of an analogue of the 1015X but built with hardware components from AMD. In other words, it is a system with a 10-inch matrix based on the junior Brazos modification.
The CPU in this particular netbook is Ontario. This is a dual-core processor with Bobcat microarchitecture working at a relatively low clock speed of only 1.0 GHz, but at the same time boasting very low TDP of 9 W.
Note that even though memory in Brazos based netbooks is single-channel one, it boasts higher bandwidth than the memory in similar Intel systems. AMD platform supports DDR3-1067, so the frequency difference is 266 MHz and it matters a lot for the integrated graphics core, which shares the memory capacity as well as bandwidth with the processor cores.
As for the graphics, Asus Eee PC 1015B uses the Radeon HD 6250 graphics accelerator integrated into the Ontario processor. The functionality of this graphics core is incomparably better than that of Intel’s GMA 3150. For example, Eee PC 1015B can easily play HD video in any popular formats, and its 80 shader pipelines working at 277 MHz frequency can even deliver decent 3D speed.
However, Ontario processor may be not powerful enough for the highest-performance netbooks out there. That is why there is another Brazos modification equipped with Zacate processor. This platform is used, for example, in Asus Eee PC 1215B. Just like its ION-based counterpart, this system features a 12-inch matrix. Moreover, its other characteristics are actually just as competitive.
Zacate processor is actually a dual-core Ontario but with higher clock frequency of 1.6 GHz and therefore, with increased TDP of 18 W. All other basic characteristics of these two processors are very similar.
I have to admit that the default graphics core in Zacate is also faster. Its frequency has been increased to 492 MHz, which makes it the fastest netbook graphics solutions out there, which on top of that supports contemporary DirectX 11 interface.
All other parameters of the netbooks selected for our today’s test session are the same. They all come with 2 GB of memory and use SATA-300 HDDs with 5400 RPM spindle rotation speed.
However, the most important thing for us in the light of the upcoming comparison of the systems’ consumer qualities is the fact that all of them use the same 56 W*h battery.
In conclusion to our description of the tested netbooks, we would like to offer you a summary specification table:
During our test session we installed identical operating system onto all netbooks – Windows 7 Home Premium SP1 x86. Here is the list of additional drivers that we used:
- ATI Catalyst Driver 11.9;
- Intel Chipset Driver 184.108.40.2060;
- Intel Graphics Media Accelerator 3150 Driver 220.127.116.11.7.2230;
- NVIDIA GeForce/ION Driver 280.26.
