1.A4 CPU single core1.0ghz.
2.PowerVR SGX 535 graphics processor
3.5 12M memory

Summary: The hardware parameters of Iphone4 are similar to those of Samsung i9000 and Meizu M9. They are A9 single-core processor, 1GHz main frequency and 45nm technology, which are basically the highest level among single-core processors. In fact, A4 processor is a slightly modified version of this processor. The difference is that the hummingbird processor is equipped with PowerVR SGX540 graphics processor, which is much better than 535 in performance and better in game control, especially 3D games.
However, based on the optimization of iOS system, the performance of Iphone4 is still much better than that of models such as i9000 even if it uses i9000 A4 processor. Whether it is running speed, multitasking or game performance, Iphone4 has unparalleled advantages. On the real performance of mobile phones, Iphone4 should actually be equivalent to or close to but slightly inferior to the second-generation models such as Samsung i9 100 (let's just say i9000 is the representative of the first-generation model), which is equivalent to the current sub-mainstream (slightly weaker than the mainstream) Android phone with dual-core 4.0-inch screen. Similar to Samsung i9 100, i9070, Meizu MX old dual-core, LG Optimus2X, htc Sensation, Xiaomi M 1, Motorola XT883, ME860, ME865, etc.
The main hardware configuration of Iphone4S is:
1.A5 CPU dual-core 800MHz
2.SGX 543 graphics processor
3.5 12M memory
4.960*640 3.54 inch IPS full screen
Summary: The hardware parameters of Iphone4S are similar to those of Samsung Orion processor, Galaxy Note and Meizu MX with dual cores i9 100. Adopt A9 dual-core processor, 1.2GHz~ 1.4GHz, with specifications of 45nm or 32nm. Similarly, the dual-core processor is basically the highest level (even with Qualcomm MSM8260, the dual-core processor with the highest frequency of 1.7GHz, because it is an A8 modified architecture, its performance may not be outstanding except for high scores). In the current Android camp, this configuration can only be regarded as the top match of the second-generation models at most (similarly, we regard the models equipped with quad-core processors such as i9300 as the third generation). At present, you can buy an Android phone with this configuration for 2000 yuan, but the price of 4S is nearly twice as high. The key lies in the excellent and powerful brand effect of the system. In fact, compared with 4, 4S, the performance improvement is not huge, far less than the gap between Iphone4 and 3GS; In addition, under the unremitting gradual optimization and improvement of Google, the shortcomings of Android system have been compensated to some extent. Therefore, the real performance of 4S can only be regarded as a little better than the mainstream (note that it is "mainstream") Android second-generation models. Similarly, Samsung Galaxy Note, Meizu MX new dual-core, Xiaomi 1S, htc One S, Motorola XT9 10 and other third-generation Android phones represented by Samsung i9300 and Meizu MX quad-core still have a certain gap and will be challenged by the latest Iphone5.
My suggestion: Apple represents a life attitude and a fashion concept. Even an arcade is sought after by thousands of people. The Excellence and uniqueness it represents are beyond the reach of many mobile phones in the Android camp at present. If the money is not bad, you can consider 4 S. It should be possible to continue to serve for two to three years or even longer without falling behind. But you can also consider the MX quad-core 16g (2399), Lenovo K860 (around 2000) and Xiaomi 2 (the futures of1999 are hard to buy) in the Android camp. These are all below 2500, and I prefer them. I won't list the rest one by one.
