The Laptop Parts
AMD's A-Series of parts for the laptop is broken into three different lines named A4, A6 and A8.
All three use the same architecture, which fuses an older K10 based processor with Radeon graphics. However, there are some significant differences between them.
The A4 is the least expensive and least powerful part. It's the only one that is dual core, but as a result the clock speeds are high relative to some of the A6 and A8 products. Radeon graphics come courtesy of 240 Radeon Cores clocked at 444 MHz. This is the least powerful graphics component on any A-Series APU, but still sufficient for basic 3D games and roughly on par with Intel HD 3000 graphics.
One step up is the A6, which is a quad-core part. In addition to the extra cores, the A6 ups the Radeon GPU to 320 Radeon cores, although they're clocked at just 400 MHz. This results in a modest performance boost.
Finally, at the top of the line, you'll find the A8. Again, this is a quad-core part. Clock speeds can be higher than the A6, but the slowest A8 has a lower clock speed than the fastest A6. The big change is the graphics, which are upped to 400 Radeon cores clocked at 444 MHz. This is sufficient for 3DMark 06 scores around 5500. Most 3D games will play well on this part, although detail settings may have to be kept low. True gaming laptops with discrete graphics are still several times faster.
