Chip Samsung Exynos 5 Octa was not as powerful

Initially, the company Samsung has introduced two versions of its flagship Samsung Galaxy S4 – with eight cores Exynos 5 Octa (model GT-I9500) own production and quad chip Snapdragon 600 (model GT-I9505) of Qualcomm. A number of Western observers have tested both the smartphone in synthetic tests and found out what their differences.

Exynos 5 Octa was slightly faster in some synthetic benchmarks (within 10%) ahead of a smartphone with a Qualcomm Snapdragon processor 600, but the latter in this case showed the best results in longer battery life. So between the two versions, in principle, did not yield to each other.

However, resource Anandtech has performed a detailed review of both the smartphone and the variations found very interesting thing – in normal mode graphics accelerator in the Exynos chip is clocked at 480 MHz, while the popular benchmarks (Quadrant, AnTuTu, GLBenchmark) it automatically overclocked to 532 MHz, gave him immediately increase by 11-13%. After the release of these applications was the frequency in its place.

It is said that Samsung deliberately decided to put its own chip in the best light for browsers and potential buyers – they are all guided not just by words, but also on the benchmark results. And they were rigged – in reality Exynos 5 Octa was no better than the Qualcomm chip which, moreover, is more energy efficient.

In the same popular synthetic benchmarks has been elucidated yet another interesting thing. The frequency of the processor after the launch of these applications is automatically set to the maximum – and it concerned with Snapdragon smartphone versions 600 and Exynos 5 Octa.

Thus, it allows to achieve the best results in each test. Under normal circumstances, the processor before starting the test is always in quiet mode with low frequency and “accelerated” to the maximum only after clicking the start of testing.
