The iPad 3 vs. the iPad 4

What's new with the iPad 4?

If you are thinking about buying a used iPad, the iPad 3 and iPad 4 may offer the biggest savings. The iPad 3 was the first iPad to offer a Retina display. Still, other than a larger graphics chip to help power the higher resolution screen, it was mostly an iPad 2. The iPad 4 also has a Retina display, but it comes with a faster processor and a modern connector.

Overall Findings

iPad 3
  • Single-band antenna.

  • Old-style 30-pin dock connector port.

  • Relatively slow A5X processor.

  • Few available accessories.

iPad 4
  • Dual-band antenna.

  • Speedy Lightning connector.

  • A6X processor delivers twice the speed.

  • Many available accessories.

The iPad 4 was the first iPad to debut in fall rather than spring. With its new processor, it was the first major upgrade to the iPad since the iPad 2.

Processor Speed: A6X Shines

iPad 3
  • Relatively slow A5X processor.

  • Quad-core graphics.

iPad 4
  • A6X processor delivers twice the speed.

  • Quad-core graphics.

If Apple used the same system of naming the iPad that they used with the iPhone, the iPad 4 would have been named the iPad 3S, and the S would be for speed. The biggest difference between the iPad 3 and iPad 4 is a processor that produces twice the speed both with graphics and processing power.

Many thought the A6X might make its debut with the iPad 3, but Apple did not want to sacrifice any battery power in an iPad that already needed as much as possible to deliver the Retina display. The A6X was delayed to make sure it was ready for mass consumption, including being energy efficient.

Connector: Lightning Beats 30-Pin

iPad 3
  • Old-style 30-pin dock connector port.


  • Few accessories available.


  • Single-band antenna.

iPad 4
  • Fast Lightening connector is speedy.


  • Many accessories available.

  • Dual-band antenna.

Remember the old 30-pin connector? It may only be a few years since the Lightning connector replaced it, but it seems like ancient history. The Lightning connector got a lot of bad press when it first debuted, with many people believing it was simply a move by Apple to force people to buy new accessories.

Flash forward a few years, and we have an iPad Pro with speakers at each corner, a feature that might not have worked out as well with a bigger adapter at the bottom of the iPad. 

The lack of a Lightning connector may be the biggest detractor to buying an iPad 3 over an iPad 4. The lack of speed won't show as much when browsing Facebook or streaming movies, but the lack of a Lightning connector makes it harder to find accessories that fit the older iPad.

Cameras: Basically the Same

iPad 3
  • 5-megapixel back-facing camera.

  • Front-facing camera with VGA quality.

iPad 4
  • 5-megapixel back-facing camera.

  • Front-facing camera with 720p HD.

The iPad 3 and the iPad 4 both have a 5-megapixel back-facing camera with basic features such as face detection, backside illumination, and a hybrid IR filter. This camera is basically the same as the one found in the iPad Air. It wasn't until the iPad Air 2 that the back-facing camera moved up to 8 MP, and the newest iPad has a 12 MP camera.

The iPad 4 did improve the front-facing camera to a 720p HD camera, which is an improvement over the iPad 3's front-facing camera. However, unless you plan to do a lot of selfies, the iPad 3's front-facing camera is good enough for videoconferencing.

Wi-Fi: Dual Band Is the Way to Go

iPad 3
  • Single-band Wi-Fi antenna.

  • 802.11a/b/g/n compatibility.

iPad 4
  • Dual-Bank Wi-Fi antenna.

  • Accesses 2.4GHz and 5GHZ signals.

  • 802.11a/b/g/n compatibility.

The iPad 4 was the first iPad with a dual-band Wi-Fi antenna. In a technical sense, this means it is able to connect to both 2.4 GHz and 5 GHz 802.11n signals. In a non-technical sense, this means it can take advantage of some of the performance-enhancing features of newer routers.

The faster processor on the iPad 4 is great, but most of the time, mobile devices are limited by their weakest link. No matter how fast the iPad can process information, it has to get that information first, so faster downloads can certainly make a big difference.

Final Verdict

The iPad 4 is the all-around better tablet, with a faster processor, upgraded Wi-Fi, and a better front-facing camera. You'll find more accessories for it than for the iPad 3's 30-pin connector.

If you are looking to buy a used iPad and are deciding between the iPad 3 and the iPad 4, the fourth-generation iPad is worth some extra money, although both are showing their age.

Neither iPad can be updated to the newest versions of the operating system. The iPad 3 maxes out at iOS 9.3, and the iPad 4 can't be updated beyond iOS 10.
