3. Benchmarks: A Factor of Two
The two Sony portables fully meet current standards and are based on the new Centrino 2 platform.
Power Use Or Performance?
Sony has remained faithful to Intel and used Core 2 Duo processors in the new Vaios. The Z, which favors performance over battery life, uses a P9500 at a clock speed of 2.53 GHz. The TT uses an SU9400, which is designed for endurance. Operating at a lower clock speed (1.46 GHz) than the Z’s CPU, the TT’s SU9400 does have the advantage of drawing only half the power -– 25 Watts for the Z as compared to 10 Watts for the TT –— which accounts for the TT’s longer battery life.
Lots of Gigabytes
As for onboard memory, Sony has been generous with the gigabytes. Both models have 4 GB of RAM. It’s DDR3 in both cases, but varies in frequency depending on the model. The RAM is clocked at 1066 MHz on the Z and 800 MHz on the TT. But that’s not an overwhelming difference and doesn’t really reduce the TT’s overall performance.
Z Leaves TT in the Dust
Tested with PCMark Vantage (1024 x 768/no AA/8x anisotropic filtering), the two Sony ultraportables posted results that varied by a factor of two. With its power supply in high-performance mode, the TT racked up 2,326 points on the FutureMark benchmark. But the Z scored double that, with a total of 4,664.

Small correction: The Vaio Z has a 13.1" screen, not a 13.3".
Just to clear a little confusion on my side, can the laptops with their (relatively) weak graphics chips play Blu-Ray DVDs effectively ? I understood that even some desktop cards stutter under full 1080p playback. Perhaps someone could enlighten me.
lol i still don't understand why people would shell out so much money for a laptop. for $2300 i could get a desktop:
core i7
2 radeon 4870x2s
X58 mobo
6 gigs ram
for $2300 i can buy a really big Mac
the ones made ouuta bricks
