Seems that there are a few topics regarding which is better so this thread will purely compare them.
The Google Chromebook, Suddenly, Is An Enterprise Contender | ZDNet
The Google Chromebook:
- 1.7GHz dual-core Samsung Exynos 5 (ARM Cortex A15)
- 2GB RAM
- 11.6" 1366 x 768 HD display
- USB 3.0 and USB 2.0 compatibility
- HDMI port
Discussion: Exynos 5 (ARM Cortex A15) vs Tegra 3 (ARM Cortex A9)
- Tegra 3 quad core processor (ARM Cortex A9)
- 1GB RAM
- 7" 1280x800 HD display
- Only USB 2.0 compatibility
- No HDMI port
The Exynos 5 uses a dual-core, 1.7 GHz ARM Cortex-A15 CPU that can support up to 2560x1600 resolution, 1080p video at 60 frames per second, and USB 3.0.
The Cortex-A15 has been benchmarked running twice as fast as the quad-core Nvidia Tegra 3, which, coincidentally, is used in the Surface and the Google Nexus tablet.

The practicality of tablets vs laptops is another deciding factor. Picture yourself at work, school or a lecture. What do you see yourself doing?
The advantage of a tablet is its portability, however the Google Chromebook's size is also very portable.
Sometimes the Nexus 7 is seen as too small to be a practical computer. This is where the Google Chromebook beats the Nexus 7. The Chromebook can be used as a computer for office work, using Microsoft programs, and is much much faster. It has a fully functional keyboard.
Therefore, if you want something that is more practical and laptop-like while still be very portable, the Google Chromebook is for you.
However if you're just looking for a toy to play around with, occasional web browsing and gaming, then the Nexus 7 is for you.
Discussion: Technological viability
The Google Chromebook has many other features that the Nexus 7 doesn't have. This includes newer and faster CPU architecture, USB 3.0, HDMI port and more RAM.
USB 3.0 is a particularly attractive feature where uploading data into a computer may be several times faster than USB 2.0.
