AnandTech Finds iPhone 11 Pro Has 50-60% Higher Sustained Graphics Performance Than iPhone XS

AnandTech today published its in-depth review of the iPhone 11 and iPhone 11 Pro, including a detailed overview of the processor and graphics performance gains of Apple's latest A13 Bionic chip. Starting with CPU performance, AnandTech found the A13 chip is around 20 percent faster than the A12 chip in last year's iPhone models, consistent with Apple's advertised claims. However, to fully achieve that improvement, the site claims Apple had to increase the peak power consumption of the CPU cores:In virtually all of the SPECint2006 tests, Apple has gone and increased the peak power draw of the A13 SoC; and so in many cases we're almost 1W above the A12. Here at peak performance it seems the power increase was greater than the performance increase, and that's why in almost all workloads the A13 ends up as less efficient than the A12.In terms of efficiency at the A13 chip's peak performance state, AnandTech believes the higher power draw will likely result in both the chip and the iPhone being more sensitive to temperatures and prone to throttling. Apple says the A13 chip is up to 30 percent more power efficient than the A12 chip overall, encompassing all levels of performance. In terms of overall performance, AnandTech emphasized Apple's lead in the mobile chip space, noting that the A13 posts almost double the performance of the next best non-Apple chip. The site also found the A13 "essentially matched" the "best that AMD and Intel have to offer" for desktop CPUs, at least based on SPECint2006, a suite of CPU-intensive cross-platform integer benchmarks.

Apple Says A13 Bionic Chip Was Designed With Performance-Per-Watt Focus

In a feature for WIRED, Om Malik sat down with Apple's marketing chief Phil Schiller and chipmaking engineer Anand Shimpi to discuss the A13 Bionic chip in the new iPhone 11, iPhone 11 Pro, and iPhone 11 Pro Max. Malik first provides an overview of the A13 chip's specs and performance improvements:8.5 billion transistors, an approximately 23 percent increase over the A12 chip's 6.9 billion transistors Six-core CPU: two 2.66GHz high-performance cores named Lightning and four efficiency cores named Thunder Quad-core graphics processor, an Apple-designed image processor, and an octa-core neural engine for machine learning that is capable of one trillion operations per second Up to 20 percent performance increase across all of the main components, including the CPU, GPU, and neural engine Up to 30 percent more power efficient than the A12 chipSchiller told Malik that one of the biggest examples of the performance increase this year is text-to-speech on iPhones. "We've enhanced our iOS 13 text-to-speech capabilities such that there is much more natural language processing, and that's all done with machine learning and the neural engine," Schiller explained. Shimpi noted that when designing its A-series chips, Apple focuses on both performance and efficiency. "We talk about performance a lot publicly. But the reality is, we view it as performance per watt. We look at it as energy efficiency, and if you build an efficient design, you also happen to build a performance design." The article notes that Apple's chipmaking team will study how apps are being used
