Dual-core flagship processor: deyi omap4430, Qualcomm msm8260, hunters s5pv310, tegra2 horizontal advantages and disadvantages comparison

Qualcomm msm8260
Excellent: high frequency, generally about 30% higher than other brand products during the same period, resulting in improved CPU integer performance. General document processing and daily applications can reflect integer performance.
Lack: 1. Power Consumption. the power consumption of asynchronous dual-core under the 28 nm design should be lower than that of other A9, but the power consumption of 45 nm is higher than that of other A9 dual-core based on the 40/45 nm design.
2. floating point performance is poor. Asynchronization means that the second core is called only when one of the cores is fully loaded. From the perspective of floating point performance comparison, the 2/3 GB msm8260 is only of the GB exyons4210. Floating-point performance is mainly used for multimedia applications that require a large amount of computing bursts, such as soft-decoding videos and 3D games. Apply a metaphor: when a bullet hits the wall, there is a piece of earth falling, the floating point operation is strong, and the dust may also be shown.

NVIDIA tegra2
Excellent: GPU dedicated for game optimization. Needless to say, this is an old line on the desktop platform.
Missing: castrated neon. This disadvantage is very large, which leads to a low processing capacity for videos above 720 p during video playback. Only a few P/P formats can be played. Especially when videos of more than P are deployed on the network.

Ti omap4430
Excellent: 1. sgx540 video card, the most compatible (same as iPhone)
2. Superior Video performance.
Missing: no obvious defects. If the unit price is high, consider it as follows:). In addition, it supports 1 gb ram. For details, refer to the BlackBerry playbook.

Samsung s5pv310Exyons4210
Excellent: 1. the GPU performance exceeds the doubled (more than one) of the above U GPUs. It can be used with software for anti-aliasing (only in Android)
2. Superior Video performance.
Lack: the compatibility issue has not been completely solved, and about 10 3D games cannot be played or have bugs.

Finally, it is important:
1. In addition to Qualcomm, the above CPU performance is similar (all based on the same architecture, so basically only focus on the GPU part)
2. Fever. All dual cores are about half a half-width pair. In actual tests, it is easy to exceed 45 degrees within 15 minutes. Those with low Ti fever have been verified by lg3d to be pure yy.
3. the compatibility of the software (non-game) is not related to the CPU and GPU, but only to the resolution and screen ratio. The compatibility sorting is: WVGA> fwvga> qhd. Asynchronous dual-core is a bridge missing
