![]() The Cortex-A7 is basically a renewed and improved successor to the older Cortex-A8 which has been used in Apple's iPhone 4 (Apple-A4 SoC) among others. IP-core specialist ARM currently offers its customers three main designs (omitting the extreme low-end solution, the Cortex-A5): More than enough reason for us to analyze the current state with this article and to even take a glance at possible future trends.īoth the x86 and the ARM segment offer a number of different architectures for different market segments in terms of crucial criteria such as performance, power consumption and price. The end of this development is not hard to see: Instead of existing next to one another as before, ARM and x86 will increasingly have to compete for the same markets. Thus, x86 systems have finally become capable of being used in compact tablets and smartphones. Starting with the original Intel Atom CPU way back in 2008, Intel and AMD have managed to construct ever thinner and longer-lasting laptops thanks to increased integration densities and ever smaller power consumption levels. While ARM chips gain performance increases, ultra-mobile x86 CPUs take the opposite way. At the same time though, power consumption has risen too, resulting in throttling issues in smartphones and tablets becoming more and more common. Today's CPUs come with four cores, clock speeds of around 2.0 GHz and a drastically improved micro-architecture, yielding 10 times the performance. Four years ago, single-core CPUs with 1.0 GHz were the absolute maximum. X86 = performance, ARM = low power? Not anymore: While x86 peak performance hasn't seen much of an increase lately, ARM-based SoCs have gained steadily and quickly in the past few years, closing the gap. At 131648 points, the score is about twice as high as current-gen flagships from Samsung camp, rocking the Exynos 7420.For the original German article, see here. The overall score in Basemark X shows the S820 as a clear favorite as well, though the A9 is missing from the chart.Īnd back to our headline Antutu result. Most impressive is the comparison with the Exynos 7420 here, where Qualcomm’s solution manages almost twice as many frames per second. ![]() ![]() In the onscreen tests, where the test device has to push more pixels (2,560x1,600 resolution of the developer’s rig, versus 2,560x1,440 or even 1080p displays in the rest of the devices), the chip delivers respectable performance. In the offscreen Manhattan test of GFXBench, which is run at a standardized 1080p resolution, the chip is capable of twice the frame rate of the S810 or the Exynos 7420. The new Adreno 530, which according to the scarce information available on the matter appears to be an Andreno 430 with a few evolutionary tweaks, is actually mightily impressive. Snapdragon 820 developer unit against current chipsets in GeekBench Still, in this test, 4xKryo is comfortably ahead of 2xTwister. Multi-core results in the same benchmark show the Snapdragon 820 inching ahead of Samsung’s current-gen flagship silicon, but we’re yet to see what the Exynos 8890 is capable of. A near 60% improvement over Samsung’s Exynos 7420 in this respect, a score upwards of 2,300 points is still behind Apple’s single Twister core’s result. Over at the company’s headquarters working devices (non-commercial, naturally) were subjected to a battery of popular benchmarks and here are the findings.įor starters, single-core performance of the new custom Kryo cores, measured in GeekBench, is well ahead of anything in the Android realm. Judging by the results preliminary development units show, it may very well be capable of doing so. The Snapdragon 820 carries the huge responsibility to restore Qualcomm's leading-position in high-end mobile chipsets, undermined by the unfortunate Snapdragon 810.
