Good day everyone,
We performed some benchmarking tests on 2 tablet engineering samples that we have, 1 equipped with the Core i5 4202Y and the other Core M 5Y10c, and we thought we'd share our data since it might be informative to anyone else also interested in comparing the 2 architectures.
Both tablet samples have the same specs otherwise:
- 4 GB RAM
- 64 GB SSD
- 1920x1080 LCD touchscreen
- 6000 mAH battery
In both cases the OS used is Fedora 21 with Gnome 3.14 user environment and Linux kernel v3.17.8.
I've attached the benchmarking results for quantitative comparison, so I will just briefly summarize:
General performance -
Both the Core i5 and Core M models performed very well in start up & shutdown times, far better than most Android devices and comparable with high-end Windows 8.1 laptops/desktops. Battery life can't beat some of the energy-saving tablets out there like the iPad Air, but still beats out most laptops.
Web browsing -
Again both Core i5 and Core M models rendered web pages & dynamic HTML5 content very well, with little difference from each other, and significantly ahead of tablets & smartphones even with quad-core ARM chips.
This is where the Core i5 model has a visible lead over the Core M model. Multi-threading capabilities (e.g. compiling Linux on 8 threads) on the Core i5 are around 30% better than on the Core M, with similar results for scientific/engineering applications as shown by the CERN ROOT benchmark (which tests things like random number generation, curve-fitting, pattern-generation & Monte Carlo simulation).
3D Graphics -
To be honest this is where both models delivered only mediocre performance... integrated graphics has never been Intel's core strength I suppose. Still the Core i5 model again showed visible advantages over the Core M model in rendering 3D objects in OpenGL.
Other issues that emerged during our testing:
- Core i5's 7 hour battery life compared to Core M's 6 hours
- Core M's touchscreen doesn't work after waking from sleep
I believe these 2 issues are due to the Linux kernel not updated with the latest Intel ACPI drivers for Core M yet, leaving the OS to use the older ACPI drivers that aren't fully compatible with Core M. Given Intel's past and present contributions to Linux, I also believe it wouldn't take long for Intel to fix these issues, am I correct?
The Core M tablet wins out in price and weight, while the Core i5 tablet wins out in performance and track record.
(Multi-tasking & virtualization performance weren't benchmarked comprehensively enough at the time of writing to be included here.)
If anyone has any questions about our methodology or updates about Core M support in Linux or know of any methods for us to improve the results, please feel free to share with us.
We hope you found the info here helpful! =)
