What is the processor of iPad 4?

The processor of ipad4 is Apple A6X. The Apple A6X dual-core processor integrates two CPU cores and four GPU cores. Its CPU and graphics performance is twice that of the A5X processor. Each GPU core is divided into 9 sub-cores, 4 in a group, two identical sub-cores, plus a central core; this processing method will increase the maximum clock frequency, thereby bringing better graphics to the iPad 4 processing power.

#The operating environment of this tutorial: iOS 11 system, iPad4.

iPad (4th generation) is the fourth-generation iPad product released by Apple on October 24, 2012 (Beijing time) at a special launch event in California, USA.

The iPad (4th generation) has a traditional Home button on the front; the body color is black or white.

iPad (4th generation) equipped with Apple A6X dual-core processor; 2048 x 1536 pixel resolution; 9.7-inch IPS Retina display ; 5 million pixels on the rear and 1.2 million pixels on the front. In the GLBenchMark test, the iPad (4th generation) scored 2059 points.

Apple A6X processor

The A6X processor integrates two CPU cores and four GPU cores. Its CPU And graphics performance is twice that of the A5X processor. The A6X isn't just about cramming a little more stuff under the skin of the A6.

The GPU core is divided into several sub-cores. Each GPU core is divided into nine sub-cores, a set of four, two identical sub-cores, plus a central core. This processing method will increase the maximum clock frequency, thereby bringing better graphics processing capabilities to iPad 4.

Comparison between A6X processor and A6

The area of ​​A6 is 94mm², while A6X has 123mm², so in terms of area, A6X is also 30% larger than A6. The extra space is used to install the GPU core. The A6X’s GPU cores have been increased from 3 to 4. What's clear is that each GPU core is slightly larger than the A6's GPU cores.

Each GPU core of A6X is 8.7mm², and the size of a GPU core of A6 is 5.4mm². Therefore, how much space does A6X need to increase to accommodate 4 new GPUs? core. In other words, the A6X is 29mm² larger than the A6, and Apple uses 18.6mm² to increase the GPU core.
