Teardown: Asus eeePad Transformer Prime
As a first; the Asus eeePad Transformer Prime is actually thinner than Apple's iPad2 (8.3 vs 8.8 mm).
"With the back off, we see the usual large battery, but once you start pulling things apart you can see a main board and a number of subsidiary boards – the touch screen controller, some switches, and the camera flash LED are all on separate boards", writes Chipworks. The main circuit board has the components all on one side. The iPad2 board is half the size, but components are distributed on both sides. This would also explain, why the eeePad is slightly thinner. Another comparison - both batteries have the same capacity (25Wh), making battery life similar. The teardown did not reveal a PoP for the processor, but that - in fact - the nVidia Tegra 3 processor (no markings on the back) and the 1-GB Elpida B8132B2MA memory are physically distinct. This is a WiFi only device, with the WiFi module being a AzureWave NH615.
