The Intel Atom Clover Trail processor is it really more efficient than competing ARM chips? One
analyst has decided to redo the benchmarks.
In the month of June, ABI Research caused a sensation by publishing a report in which it announced that the Atom 'Clover Trail' Intel chip consumes only 60% power of a rival ARM chip, a comparable performance. Today, another analyst shall simply because these results, especially since the author has revised its benchmark scales.
Following a new passage to the test bench, Jim McGregor of Tirias Research says that the chip Clover Trail 2 GHz found in the Lenovo K900 smartphone displays for the CPU, a result of 20 % lower than the benchmark AnTuTu, and RAM, a result of 50% lower. This benchmark, updated version 3.2.2, have been corrected after the release of pro-Intel chip tests. It seems that the software has jumped some steps, giving the advantage to the Intel chip. What does this mean? After the test, ABI Research said that Clover Trail chip present in the Lenovo K800 consumes only 47% power of the 300 Krait chip integrated into the American version of the Samsung Galaxy S4. If in terms of performance, both chips were comparable in terms of power-to-performance ratio, the Intel has a significant advantage.
New tests less favorable to Intel
But new tests provide more conclusive results, and the difference between the two chips is more consistent with what we know: the last always benchmarks indicate that Intel chips consume less power, but they are also slower. Jim McGregor has published a slew of benchmarks that show the chip 300 S4 Krait (or Exynos Octa present in some European versions of the S4) retained a significant margin on Clover Trail, up to 2.5 times in some benchmarks as Linpack Multi-Thread. But there is another problem. Power estimates made by ABI is based on DC, on the assumption that the operating voltages are roughly comparable. ABI did not measure the total power (probably because the CPU tested were housed inside a telephone, taking into account variables such as the screen resolution).
In early June, Lenovo has started shipping the K900 Asia. As long as there will be no smartphone incorporating a chip Clover Trail in the world - especially in Europe - we can conclude that the differences between the two chips remain quite academic.
