ASUS Taichi 21 (11-inch) - Dual Displays

Launch SRP: S$2698

Benchmarking and Performance

Benchmarking and Performance

Like most Windows 8 convertible Ultrabooks today, the ASUS Taichi 21 pulls double duty, as a big (and heavy) tablet when you need it to. However, it’s first and foremost an Ultrabook, with Ultrabook components such as a consumer-ultra-low-voltage (CULV) processor.

As such, its performance is expected to be on par, with other premium Ultrabooks (with SSD instead of a mechanical HDD) out in the market. To give you a gauge on where it stands, we’ve selected some of the latest Windows 8 Ultrabooks to compare it against. Also take note that the Sony Vaio Duo 11 scores are taken from a Core i5 variant, instead of a Core i7 variant stated in the table.

PCMark 7

PCMark 7 is a benchmark that puts the notebooks through a standard battery of tests. The tests puts stress on each of the machine’s components (CPU, GPU, SSD) and gives a score based on how well they hold up. An overall score is then given, which gives us an idea of how the machine performs.

Here, the ASUS Taichi with its 1.9GHz Intel Core i7 processor manages to stay slightly ahead of the rest. It shows that having a faster clock speed does translate to a performance boost. The advantage it has here is negligible in real world usage, but it can come in handy for more compute intensive tasks such as video transcoding and the likes.


3DMark 11 & Far Cry 2

The onboard GPU that comes with the Taichi’s Ivy Bridge processor is the same as those found in the other Ultrabooks. This means the Taichi’s graphic performance is the same as other Ultrabooks, even though it has a slightly higher clock speed.

This two benchmarks aren’t here to tell you that the Taichi can excel in gaming, because it can’t. Instead it’s here to show you that everyday tasks that involve the machine’s GPU like rendering of system animations and web pages, are no problem for the Taichi as it can definitely keep up with other Ultrabooks.

The Good
Dual full HD displays (one with touch capability)
Sturdy build
Good keyboard and trackpad
Novel approach to convertible notebooks
The Bad
Niche product
Battery life could have been better
Smudge prone exterior facing glass lid
Interior display should have been touch capable
