Intel CloverTrail+ processor mops the floor with its competitors

Intel Clover Trail Current Draw Comparison

There’s no denying that smartphones are becoming pretty powerful; quad-core processors are now the standard in high-end handsets and clock speeds are creeping up into laptop territory as well. However, the one big problem that mobile technology still faces is the limitations imposed by running processors on a battery.

The results show a benchmark score followed by the average and peak current draw during the test. Intel’s chip scores highest on the most tests and draws the least current, and it’s only beaten by the Exynos 5 Octa when it comes to GPU performance.

We’re mostly interested in the CPU performance and current draw results from this test, as GPU performance is dependant on other chip manufacturers. Three of the processors scored roughly the same CPU result (around 5000) including the CloverTrail+ chip, the Exynos 5 Octa, and the Qualcomm Snapdragon 600. The test pretty much matches the initial Lenovo K900 benchmark that we saw earlier this year.

Just looking at the base CPU score alone, the dual-core CloverTrail+ comes out on top by a couple of hundred points, followed by the four Krait 300 cores in the Snapdragon 600, and Samsung’s Exynos 5 Octa chip, which houses four Cortex A15 and four A7 cores, following closely behind. But the real surprise can be seen if you glance over slightly to the right: the CloverTrail+ draws significantly less current than its competitors.

The average CPU drain on the Lenovo K900 was just 0.85 amps, whilst the supposedly energy efficient Exynos 5 Octa Galaxy S4 drew an average of 1.38 amps, and the Snapdragon 600 drew a massive 1.79 amps on average. Peak current draw is even more telling, 1.05 amps peak for the Z2580, 1.71 amps peak for the Octa, and 2.10 amps for the Snapdragon 600, making the CloverTrail+ not only the fastest but also the most energy efficient processor out of these current top of the line components.

ABI engineering Vice President Jim Mielke summed up the company’s findings:

The ARM architecture used by nearly all of Intel’s competitors is well known for its low power performance but in bringing the processing power up closer to PC levels, the current drain has taken a significant hit.

The closest competitor to the current draw of the CloverTrail+ is the rather outdated Tegra 3, which uses four ARM Cortex A9 cores rather than the newer, and more power hungry, Cortex A15 cores found in the Exynos 5 processors. But the old Tegra 3 languishes really far behind in terms of performance, scoring only half as well as Intel’s processor.

It seems that Intel has finally managed to find the right balance of power and energy efficiency after some dubious performance results with its previous Atom chips. But we’re still waiting to see more handset manufacturers implement Intel’s processor technology.

BayTrail will be even better

With high-end smartphones pushing the performance and energy boundaries, Intel seems to have found the sweet spot. …read more
