What is the difference between iphone 3gs and iphone 5

A higher pixel density translates into more clarity and sharpness for the images rendered on the screen, thus improving the quality of the viewing experience. Resolution is an essential indicator of a screen's image quality, representing the maximum amount of pixels that can be shown on the screen.

The resolution is given as a compound value, comprised of horizontal and vertical pixels. The bigger the screen size is, the better the user experience.

It was designed to overcome the main limitations of conventional twisted nematic TFT displays: limited viewing angles and low-quality color reproduction. You can operate the device easily, by pressing the screen with your fingers.

The device can display 3D images without the need for wearing special glasses. The display's special construction allows viewers to get a sense of an image's depth by tailoring its position to fit the user's perspective.

Performance 1. RAM 0. Random-access memory RAM is a form of volatile memory used to store working data and machine code currently in use. It is a quick-access, temporary virtual storage that can be read and changed in any order, thus enabling fast data processing.

CPU speed 1 x 0. The CPU speed indicates how many processing cycles per second can be executed by a CPU, considering all of its cores processing units. It is calculated by adding the clock rates of each core or, in the case of multi-core processors employing different microarchitectures, of each group of cores. The device has a standard memory slot such as an SD or micro SD card slot that enables you to extend the built-in internal storage with affordable memory modules, or easily retrieve data, such as photographs, from the memory card.

The internal storage refers to the built-in storage space available in a device for system data, apps, and user-generated data. With a large amount of internal storage, you can save more files and apps on your device. Small semiconductors provide better performance and reduced power consumption. Chipsets with a higher number of transistors, semiconductor components of electronic devices, offer more computational power. A small form factor allows more transistors to fit on a chip, therefore increasing its performance.

It also allows you to run bit apps. NX bit helps protect the computer from malicious attacks. AES is used to speed up encryption and decryption. Cameras 1. The number of megapixels determines the resolution of the images captured with the main camera. A higher megapixel count means that the camera is capable of capturing more details. However, the megapixel count is not the only important element determining the quality of an image. A dual-tone flash has LED lights with different color temperatures, delivering a better color balance to photos and videos.

A BSI backside illuminated sensor is a camera image sensor which captures better quality images in poor lighting conditions, and offers better overall sharpness and image quality. When recording movies they stay focussed and sharp. Slow-motion is an artistic video effect that makes time seem to go slower. It is achieved by recording a video at a higher frame-rate than the standard playback rate of 24fps or 30fps.

The iPhone 4 cost the same as it did before the 4S. They just charge more for the 4S. Posted on Aug 21, AM. To answer your question directly, no, the 3GS is not at all sluggish on iOS 5. Infact, not only does it work well on iOS 5, it will support iOS 6 when it is released in the fall. The beta versions of the software show minimal slowness on the 3GS.

The original poster said that his girlfriend was originally on OS 3. Now upgrading to that firmware has permanently slowed down her phone. Ckuan has clearly not used an iPhone 3G running iOS 4. The 3G was doomed from the start in my opinion. It has upgraded networking, and came with more features out of the box than the first generation iPhone, but it has the exact same processor and ram.

Out of the box, since day 1, I noticed it was slower than my first generation iPhone by 1 or 2 seconds loading normal apps. After iOS 4, it pretty much became a "dumb" phone instead of a smart phone, as the only thing it could do with bearable speed was make phone calls. The iPhone 3GS is probably the best step forward in speed compared to any other iPhone launch even the 4S. It's processor is actually the same exact processor used in the iPhone 4. Yes, as ckuan says, the iPhone 4 has a custom apple chip, but this chip is simply the overclocked version of the 3GS chip, repackaged with the graphics card which is the exact same , in one package.

It is nearly the same speed as the 3GS. In fact, benchmarks have shown the iPhone 4 to be slower at playing graphically intense games than the 3GS, due to it's high pixel density with the same graphics card as the 3GS, which only has a 4th of the pixels to push.

Due to this speed similarity, the 3GS runs nearly all the apps as the iPhone 4 does. Most app store apps support the 3GS and above. Apple still sells the 3GS. The 3GS has been selling for 3 years, and still hasn't been obsolete. When iOS 6 releases, the 3GS will have nearly the same features as the iPhone 4 actually, as of beta 4, the only feature that iPhone 4 has over the 3GS in iOS 6 is offline reading lists, which can be easily solved by downloading any similar app in the app store.

Since the 3GS is cheaper in your area than the iPhone 4, if the question is whether you should get a 3GS, the answer is a resounding yes. Older doesn't mean it's horrible. I actually believe the 3GS is probably the best iPhone ever made.

Just look It's got comparable speed to the iPhone 4, which is still considered to be new, and used by millions of users. It supports nearly all the apps in the app store. It's cheaper, but it's got nearly all the features of the iPhone 4 on iOS 6. Buy the 3GS, don't be dissuaded to pay extra for a newer iPhone, or buy some random android device just because the 3GS doesn't have "Apple custom chips" or is too old. Posted on Aug 21, PM.

It was impossible for her to use the facebook app, for example - would take about seconds to open, and feel very sluggish when scrolling down or up. Typing was also a pain - she could write almost a whole word before the input start to appear on screen.

I was hoping that the same would happen to the iPhone 3GS and iPhone 4, and as you said, that seems to be the case. Your explanation was very good, I will definitely buy the 3GS for her. She thinks that my iPhone 4 is too fragile because of the glass, and doesn't really care for the higher resolution, so I think she'll be pretty happy with it. It really is impressive that the 3GS will support iOS 6. Aug 23, AM in response to ckuan In response to ckuan.

Your experiences with 2 iPhones don't have any weight against all the thousands of 3G users who have complained over the lagginess of the 4. No difference. Please do your share of research before accusing me. I am actually quite amazed how you are a level 5 forum member with thousands of points.

And yes, the iPhone 3GS and 4 run on the exact same processor architecture. While it may not be the exact same chip, they are both Cortex A8 processors, clocked at different speeds, and packaged without and with GPU's for the 3GS and 4 respectively. As a developer, I clearly know that the 3GS and 4 are pretty much the same performance target for me while developing apps.

Aug 23, AM. The iPad 2 is actually faster than the new iPad in graphic intensive games. Aug 23, PM in response to tpulak In response to tpulak. You as a developer never heard of optimizing. All the software I wrote, I was able to at least double the speed in the new release. The processors are still the same. According to your remark, Android phones have higher specs so logically should be faster than the iPhone.

So decide now, are they the same or not? For my money they are different, Apple would not spend all that money just to put the apple logo on a chip that is the same. Now, finally for the exact arguments you have been saying. Aug 23, PM. I can confirm what tpulak says. I am actually using iOS 5.

Note that in comparison to 4S the front camera is missing, LED diode is missing and it is a bit slower.
