Note II and 1.7 GHz Tegra 3+ in the HTC One X+. These would certainly perform better than their basic versions, but are not actually a different processor family, just one with a 0.2 GHz step overclock, so we wanted to stick with stock.That is why we gathered the existing quad-core mobile chipsets at the office table, and ran a few standard benchmark tests to decide who is who in the world of multicore. Of notable absence are the overclocked 1.6 GHz Exynos 4412 in the
LG Optimus G with its Snapdragon S4 Pro, the Samsung Galaxy S III with the Exynos 4412, the LG Optimus 4X HD with Tegra 3, and the new entrant - Huawei Ascend D quad XL - with its homemade K3V2 quad-core processor.We used the
As you can see from the results in the video below, all except one deliver a similar performance, with Huawei's processor delivering a pleasant surprise in the graphics department, and the Exynos proving to be a great all-arounder.
The big outlier is the S4 Pro, however, and we have to admit that Qualcomm has done a great job with this processor, whose cores are using instructions from the Cortex-A15 architecture of ARM, just like Apple's newly-minted A6 processor. The weakest performer most of the time was the Tegra 3 chip, which can be expected, as it was the first quad-core processor announced, and is done with the older 40nm process.
Next week is rumored to see the unveiling of a Samsung Nexus tablet with the real-deal Cortex-A15 processor of the Exynos 5-series, so we can't wait to see the benchmarks from that one.
