Is Qualcomm S4' s mobile phone worth buying? Will its performance be killed by eight nuclear or quad-core of A 15 at the end of the year?

First, there must be a 15 dual-core architecture this year, and the probability of a 15 4 core is only half and half. The karyotype of a 15 8 is estimated to be next year, which may not have appeared yet. At present, chip manufacturers are waiting for the arm V8 instruction set and its architecture released by ARM in the third quarter of 20 12. If the performance of the new architecture is satisfactory, the a 15 8 core will be abandoned.

At present, Samsung exynos5450 has been developed by a 15 4 core. If the fixed frequency is 1.5-2.0ghz, the highest performance will be 4x5.0x2000 = 40000mips, and the fixed frequency may not be 2.0ghz.

At present, a 15 dual-core confirms the core omap5430 and omap5432 of Samsung exynos5250, with a fixed frequency of about 1.5ghz, and the performance is expected to be 15000 MPs, which is close to quad-core a9. Because there is little difference between a9 4 core and a 15 dual core, TI gave up a9 4 core and went directly to a 15 dual core.

Secondly, Qualcomm Snapdragon s4 is a big category, including msm8960 (including msm8260a without lte baseband), msm8930 and msm8974. More precisely, s4 is krait architecture, s3 is Scorpio architecture dual core, s2 is 45nm Scorpio architecture single core, and the definition of s 1 is confusing.

Msm8960 is 9900mips at 1.5ghz. At present, some models are equipped with 2g ram to counter a9 4 core+1g ram. 2.5ghz Krait4 core can reach 4x3.3x2500=33000mips, which supports 40-bit addressing expansion and theoretically supports 4g-8g ram. Generally speaking, Qualcomm s4 can expand ram through manufacturing process to compete with a9 4 and a 15 dual-core and a 15 4 core.

Third, there is excess performance and limited performance improvement.

At present, Android system is running in software and hardware, which leads to other systems being forced to follow up. The hardware of Android system has developed too fast, and the current system, software and games have failed to give full play to the rapid performance of hardware. Android plays a multi-core dual-thread role, and the 4.0 version of forced gpu rendering has not been popularized, let alone the 5.0 version will come out again. In the case of single thread, the current Android hardware tends to have excessive performance, and a9 dual-core can not be fully utilized, let alone a 15 architecture.

For Android, 2g ram, 10000 mips is enough.

The emergence of dual-core is due to the limited frequency increase of single core, and the performance of an a9 dual-core is equivalent to that of an a9 single core with twice the frequency. But when two people cooperate, no one cooperates alone, and the dual core is also 1+ 1 < 2. The hint range of 4 cores is smaller than that of single core, and the more cores, the lower the performance improvement. Many people have made great improvements to Android by referring to the arm 1 1 architecture. If you compare and refer to the a9 dual-core of Android now, the prompt experience you can get will not be great.

In short, with the current msm8960+2g ram model, a9 4 core+1g ram with 40nm process can be suppressed by 28nm process core 2g ram. This configuration will not be eliminated in the next three years.

Can use seconds, at least there must be an obvious gap of more than 1 times, a 15 dual-core, a9 4 krait dual-core is not more than 2 times, a 15 4 krait 4 core is not, talk about seconds, anyway, it is a temporary disadvantage in theory, that is, the difference between high-end and high-end. Ordinary applications can't find much gap unless it is some games that consume performance.
