Performance benchmark Cortex-A15 VS Samsung 5250

ARM area, Cortex-A15 of the current performance the most prominent is the latest processors, although at present, Samsung has launched a related product, but its good momentum of development for other mobile processor manufacturers off to a good start. Shortly before the launch of the Nexus 10 Chromebook by A15 architecture Exynos and Samsung 5250 dual-core processors, up to 1.7Ghz, from showing encouraging results. Currently has foreign developers in the Exynos 5 are installed on Ubuntu 12.04 operating system based on Linux kernel and NVIDIA Tegra 3, Intel Atom Z530/N270/D525 and the Core multidimensional compared i3-330M, case read.

Intel Core i3-330M:X86 (Nehalem) architecture, dual-core four threads, 32nm manufacturing process, frequency 2.13GHz, cache 512KB, three-level cache 3MB

Platform specific testing Description: Moschino new iPad case

Held prior to testing, to introduce today's leading Samsung Exynos 5250: Samsung Exynos 5250 integrates two ARM A15 CPU core frequency 1.7GHz, with a graphics core Mali-T604.

▲ Cortex-A15 architecture diagram

Test results are as follows:

▲ Pybench: the smaller the number, the better. I3-330M lead significantly, Exynos 5250 came in second, and outstanding than the Atom D525.

• Smallpt global illumination rendering: the smaller the number, the better. I3-330M-leading, followed by the Atom D525,Exynos 5,250 third, NVIDIA Tegra 3 is generally, at the bottom, compared with single core Atom there are gaps.

▲ Primesieve prime numbers sieves method, known as small as possible. I3-330M lead Atom D525 and Exynos 5250 gaps, Z530 and N270 opened a wide gap.

• Parallel parallel BZIP2 file compression, the smaller the number, the better. I3-330M-leading, followed by Exynos 5250,Atom D525 ranks third, the difference is not obvious. NVIDIA Tegra 3 performance was good.

▲ C-Ray multithreaded testing, the smaller the number, the better. I3-330M-leading, followed by Exynos 5250,Atom D525 ranks third, and this gap has still not evident. NVIDIA Tegra 3 easily exceeded a single core Atom.

▲ Timed PHP compilation compile test: the smaller the number, the better. I3-330M fast, Exynos 5250 with a tiny lead over Atom D525 ranked second.

• 7-Zip file compression, the larger the better. Exynos 5250 slightly inferior than the Atom D525, dual-core X86 play the advantage.

• H.264 video encoding tests, the larger the better. Exynos 5250 reached 10.62 FPS encoding speed, easy victory over Tegra-3 and Z520 and N270. D525 is slightly better than Exynos 5250,I3 continued to maintain its leading edge.

▲ SciMark benchmark tests, the larger the better. I3 comfortably ahead, not less Exynos 5250, was second, more than the dual-core Atom.

• I3 and leading, Exynos 5250 will also be far behind Atom series, this test examines single-core performance, D525 Z530 and N270 leading is not obvious.

• I3 is still riding the dust, Exynos 5250 came in second, but the gap is large, embodied by the Exynos 5250 solo performance.

▲ Exynos 5250 this 167.9 Mflops, Intel Atom chip (N270, Z530, D525) lag behind larger i3 processor speed topped 260.62 Mflops again.

• GMPbench test: the larger the better. Intel i3 lead significantly, slightly stronger than Atom D525,Tegra Exynos 5250 3 row after three, but also outstanding than the single core Atom.

▲ FFTE test: the larger the better. I3 lead significantly, stronger than Atom D525 Exynos 5250, multicore advantage is stronger than a single core.

▲ Dolfyn test: the smaller the number, the better. I3 optimal, Exynos 5250 lead Atom D525,Tegra 3 poor, nuclear Atom some distance behind the sheets.

• LAME MP3 Encoding audio encoding test: the smaller the number, the better. I3 came in first, Exynos 5250 ahead of Tegra 3 and single core Atom, the lead significantly.

▲ PHPbench test: the larger the better. I3 optimal, Exynos 5250 lead Atom D525,Tegra 3 also caught up with and outstanding than the single core Atom.

Summary:

Judging from the overall test result, Samsung Exynos 5250 test goes beyond dual-core Atom, the leading single core Atom has obvious advantages, A15 performance other people overlooked. Although the Core i3-330M in leading the way in this test, but since it's a notebook processor, power consumption and heat are the bottleneck, it is difficult to be used in mobile products, comparison meaningless. For now, the dual-core A15 has made a very good performance, it is reported that there will be a quad core A15 processor available, if power control is in place, performance of mainstream mobile products will be comparable with the desktop products. As you can imagine, when the desktop market will further erode the mobile device.
