Tablet computing has revolutionized field sales as we know it. This change can be felt throughout the consumer goods industry and across the broader retail landscape as sales reps, managers and even drivers leverage cellular technologies and consumer-inspired business apps to get their jobs done each day.
While GreatVines Mobile is based on the HTML5 standard and essentially platform agnostic, many GreatVines clients rely on the convenience of using iPads, and each new version of the hardware has included significant performance improvements. Going from the 2nd generation to the 3rd, there were moderate gains, while significant boosts were a highlight of both the 4th generation and the Air.
One of the most pertinent hardware upgrades in the iPad line occurred in the 3rd generation, which was the first to receive 1GB of RAM vs 512MB on the previous generations. For this reason, the GreatVines mobile application is not supported on versions prior to the iPad 3rd Generation.
Also worth noting is that while the iPad 3rd and 4th generations and Air all have 1GB of memory, all memory is not created equal. The iPad Air utilizes 1GB of DDR3 RAM, which is a lower power and faster performing hardware.
This chart details the evolution of the CPU and SOC (system on chip) specifications on the various models, showing performance boosts from generation to generation.
iPad 2nd & 3rd Generations
While the iPad 3rd generation device did receive an upgrade to both its RAM and its SOC, it utilizes the same CPU as the iPad 2: 1 GHz dual-core ARM Cortex-A9 chip. It is worth noting that the iPad 2 launched with this CPU on March 1st, 2011, making this CPU now effectively 3 years outdated.
iPad 4th Generation
The iPad 4th generation was released in November of 2012, finally receiving an upgrade to its CPU, and the first significant overall performance boost in the history of the product line. This device has a marked improvement over the previous generations.
Released one year after the 4th generation device, the iPad Air consists of new CPU and SOC hardware, and continued significant leaps in performance. Rumors are that a 6th generation iPad may be released in the coming months along with the iPhone 6. From a GreatVines perspective, we would love to see an even faster CPU and memory increase, as these are the primary drivers behind the WebKit (Safari) which is at the heart of our HTML5 Cordova application.
